Introduction __________________________________________________________ 1.3 What is [n]etiquette? Before posting or emailing a question, please use the available local resources, such as the OpenVMS manuals, the HELP, and the resources and information in and referenced by this FAQ. Please use these first. Also please specifically read the release notes and (if appropriate) the cover letter for the product you are using. (The release notes are generally placed in SYS$HELP:.) Quite often, these simple steps will allow you to quickly find the answer to your own question-and more quickly than waiting for a response to question posted to a newsgroup, too. These steps will save you time, and will also help ensure you have a good reputation with the folks that might be included to answer one of your future questions, a question not covered in these resources. Put another way, if you do not want your questions to be ignored in the future- and please remember that the folks in the newsgroups do not have to answer your questions-you won't want to "annoy the natives" by asking a question that has already been answered far more times more than you might have realized, or a question whose answer is readily available had you made a small effort. When posting, please consider the following suggestions: o There is no particularly reliable way to recall, erase, delete, or otherwise hide a message once it is emailed or once posted. Once your message has reached an external email server or multiple news servers, the entire text is effectively a permanent fixture of the network. And using the available search engines, a fixture that is easy to locate and to correlate. (Do not assume that all tools or archives will honor the do-not-cache attributes, either-postings marked as such can be among the most interesting ones to cache, after all.) For details on some of the many available archives, please see Section 1.2.3. 1-7 Introduction o Include a valid e-mail address in the text of your posting or in a "signature" appended to the end. Reply-to addresses in headers often get garbled. Anonymous addresses can also simply be ignored, as fake addresses are regularly used by folks that are "trolling" and by folks that are spamming. (Though to avoid spam-harvesting of your email address, consider adding characters or a field into the address-but remember to include details around which characters or fields should be removed or altered if you decide to be particularly clever here.) o If you are submitting a question, please be as specific as you can. Include relevant information such as processor type, product versions (OpenVMS and layered products that apply), error message(s), DCL command(s) used, and a short, reproducible example of problems. Say what you've tried so far, so that effort isn't duplicated. Keep in mind that there's not yet a telepathy protocol for the Internet. (The more detailed your description, the better that people can help you with your question.) o If responding to a posting, include in your reply only as much of the original posting as is necessary to establish context. As a guideline, consider that if you've included more text than you've added, you've possibly included too much. Never include signatures and other irrelevant material. o Please be polite. If the question isn't worded the way you think is correct or doesn't include the information you want, try to imagine what the problem might be if viewed from the poster's perspective. Requests for additional detailed information are often better sent through mail rather than posted to the newsgroup. o If you have a problem with HP (or any other vendor's) product, please use the appropriate support channel. Do not assume that newsgroup postings will get read, will be responded to by the appropriate developers, or will be later followed up upon. 1-8 Introduction o If you are posting from a web browser, news reader or if you are posting via email sent to INFO-VAX, please turn off MIME, vcard, attachments, and other mechanisms that assume anyone reading the post has the corresponding capability-use the text-only option of your web browser, news reader, or mailer. Usenet is traditionally a text-only medium, and many comp.os.vms participants will use tools that have this support disabled, or that do not have this support. If the message uses MIME or attachments or such, the text of your message will be buried in a large pile of gibberish, and some tools will send multiple copies of the text within a single posting. o If you find that the postings of a particular user are uninteresting, annoying, or off-topic, most newsreaders include a filter or killfile mechanism, and many mail clients have similar filtering capabilities. Please do not "flame"-to email or to post vitriol - any individual that might annoy you, please enable and filter all of that user's postings. Posting of vitriol and of "flames" will eventually come back to haunt you; netizens and the net itself have a very large and a very long memory. Similarly, readers that decide that your postings are not worthy of reading will similarly tend to filter or to killfile all of your postings. Please play nice, in other words. Before posting your question to the comp.os.vms newsgroup or sending your message to the INFO-VAX list, also please take the time to review available etiquette information, such as that included in the following documents: widftp://rtfm.mit.edu/pub/usenet/ news.answers/usenet/primer/part1 widftp://rtfm.mit.edu/pub/usenet/ news.answers/usenet/faq/part1 widftp://rtfm.mit.edu/pub/usenet/ news.answers/usenet/emily-postnews/part1 1-9 Introduction widftp://rtfm.mit.edu/pub/usenet/ news.answers/usenet/writing-style/part1 widftp://rtfm.mit.edu/pub/usenet/ news.answers/usenet/posting-rules/part1 This information will document the etiquette of newsgroups, as well as providing you with the knowledge the vast amount of newsgroup-related information that is readily available to you, and where to find it... Note Please do not post security holes or system crashers Rather, please report these problems directly to HP. Why? So that HP has a chance to resolve and distribute a fix before other customer sites can be affected. Most folks in the newsgroups are honest and deserve to know about potential security problems, but a few folks can and will make nefarious use of this same information. Other sites will hopefully return the courtesy, and will not post information that will potentially compromise your site and your computer environment. __________________________________________________________ 1.4 What OpenVMS user group(s) are available? Encompass, the Enterprise Computing Association, is a user group comprised of information technology professionals that are interested in the Enterprise- oriented products, services, and technologies of Compaq and of the former DIGITAL. Encompass offers newsletters, the Encompass website, and offers various gatherings and related services, including symposia events and local users group meetings. Encompass is a descendent of the organization known as DECUS, the Digital Equipment Computer Users Society. 1-10 Introduction For more information on Encompass, please visit the Encompass web site: o http://www.encompassus.org/ The organization comprised of customers of Hewlett- Packard Company (HP) that is probably most analogous to the Encompass organization is Interex: o http://www.interex.org/ Like Encompass, Interex offers various services and events of interest to folks that presently work with and/or that wish to learn about HP products and offerings. Please see the Interex website for details. __________________________________________________________ 1.5 OpenVMS Support, Questions and Comments? The following section includes contacts for OpenVMS Feedback, and information on how to obtain technical support information. _____________________________ 1.5.1 Corporate contacts for OpenVMS Business Issues? The HP corporate contact for OpenVMS business issues is Ann McQuaid, the HP General Manager directly in charge of OpenVMS and OpenVMS Engineering, while feature requests and other related matters should be routed to MaryJane Vazquez, the OpenVMS Business Manager. Ann and MaryJane will quite obviously respond best to cogently-worded OpenVMS corporate-level business issues or requests. With all due respect to all involved, neither Ann nor MaryJane are appropriate contacts for technical support matters nor for technical support requests, nor for any other non-corporate-related, non- business-related issues-these questions are best routed to the local or regional customer support center; to the support, technical and engineering teams. To reach Ann or MaryJane via electronic mail, place a dot between the first and the surname, and append the expected HP.COM domain. 1-11 Introduction _____________________________ 1.5.2 OpenVMS Ambassadors? The OpenVMS Ambassadors are senior HP engineers with advanced technical knowledge and advanced training in OpenVMS, with detailed knowledge of current and future OpenVMS releases and product plans, and with contacts directly with the HP and ISV hardware and software engineering organizations developing OpenVMS and OpenVMS hardware platforms, as well as layered products and tools. Further, Ambassadors are experienced with integrating HP OpenVMS and application-specific products and ISV applications to solve specific business requirements. OpenVMS Ambassadors are based throughout the world. Your HP sales representative or HP reseller will be able connect you with your local OpenVMS Ambassador. _____________________________ 1.5.3 Contact for OpenVMS Marketing Issues and Questions? Please see Section 3.4. _____________________________ 1.5.4 Contact URLs for OpenVMS Technical Issues? For technical issues and technical support, please contact your software support organization, or your local HP Customer Support Center or HP Reseller. In North America, you can call 1-800-HP-INVENT.

What is its history? OpenVMS, originally called VMS (Virtual Memory System), was first conceived in 1976 as a new operating system for the then-new, 32-bit, virtual memory line of computers, eventually named VAX (Virtual Address eXtension). The first VAX model, the 11/780, was code-named "Star", hence the code name for the VMS operating system, "Starlet", a name that remains to this day the name for the system library files (STARLET.OLB, etc.). VMS version X0.5 was the first released to customers, in support of the hardware beta test of the VAX-11/780, in 1977. VAX/VMS Version V1.0 shipped in 1978, along with the first revenue-ship 11/780s. OpenVMS was designed entirely within HP and specifically within the former Digital Equipment Corporation (DIGITAL). Two of the principal designers were Dave Cutler and Dick Hustvedt, though with a wide variety of other contributors. OpenVMS was conceived as a 32-bit, virtual memory successor to the RSX- 11M operating system for the PDP-11. Many of the original designers and programmers of OpenVMS had worked previously on RSX-11M, and many concepts from RSX-11M were carried over to OpenVMS. OpenVMS VAX is a 32-bit, multitasking, multiprocessing virtual memory operating system. Current implementations run on VAX systems from HP and other vendors, as well as on hardware emulators; for additional information on emulators, please see Section 13.12 and 2-1 General Information OpenVMS Alpha is a 64-bit multitasking, multiprocessing virtual memory operating system. Current implementations run on Alpha systems from HP, and other vendors. OpenVMS has also been ported to the Intel IA-64 architecture, and specifically to HP Integrity systems using microprocessors from the Intel Itanium Processor Family. This implementation of OpenVMS is officially known as "HP OpenVMS for Integrity Servers" and more commonly as "OpenVMS I64", and it operates in the native Itanium IA-64 architecture and 64- bit environment. OpenVMS I64 provides support for applications requiring 32- or 64-bit virtual addressing capabilities entirely within the native 64-bit Itanium execution environment. (For details on this and related terminology, please see Section 14.4.5.) For more details on OpenVMS and its features, please read the OpenVMS Software Product Description at: o http://h18000.www1.hp.com/info/spd/ OpenVMS typically uses SPD 25.01.xx, SPD 41.87.xx, and SPD 82.35.xx. Additional information on the general features of various OpenVMS releases, release dates, as well as the development project code names of specific releases, is available at: o http://www.openvms.compaq.com/openvms/os/openvms- release-history.html Additional historical information-as well as pictures and a variety of other trivia-is available in the VAX 20th anniversary book: o http://www.openvms.compaq.com/openvms/20th/vmsbook.pdf For information on the FreeVMS project, and on hobbyist and educational versions of OpenVMS, please see: o http://www.free-vms.org/ o http://www.openvmshobbyist.org/ 2-2 General Information o http://www.openvmsedu.com/ Also please see the related software licensing topics Section 2.8.4, Section 2.8.1, and Section 2.15. __________________________________________________________ 2.2 What is the difference between VMS and OpenVMS? VMS and OpenVMS are two names for the same operating system. Originally, the operating system was called VAX-11/VMS; it changed to VAX/VMS at around VAX/VMS V2.0. When the VMS operating system was ported to the Alpha platform, it was renamed OpenVMS, for both VAX and Alpha (and for the Itanium Processor Family), in part to signify the high degree of support for industry standards such as POSIX, which provides many features of UNIX systems. For those versions with POSIX, an OpenVMS license allows you to install and run POSIX for OpenVMS at no additional charge; all you need is the media and documentation which can be found on the Consolidated Distribution and On-Line Documentation CD-ROMs. Support for the POSIX package on more recent OpenVMS releases is not available, various parts of POSIX such as calls from the API are being integrated more directly into OpenVMS. For more information on POSIX for VMS see question SOFT2 What became confusing is that the OpenVMS name was introduced first for OpenVMS AXP V1.0 causing the widespread misimpression that OpenVMS was for Alpha AXP only, while "regular VMS" was for VAX. In fact, the official name of the VAX operating system was changed as of V5.5, though the name did not start to be actually used in the product until V6.0. __________________________________________________________ 2.3 What's in a Name? Terminology and Products? The proper names for OpenVMS on the various platforms are "OpenVMS VAX", "OpenVMS Alpha", and "OpenVMS I64". Use of "OpenVMS AXP" and of "VAX/VMS" are deprecated. 2-3 General Information The VAX and Alpha terms are largely interchangeably used as the names of platforms, of processor or microprocessor implementations, and of the respective computing architectures. Somewhat confusing to long-time OpenVMS users, Intel IA-32, IA-64, and EM64T, and AMD AMD64 are the names of various computing architectures and of architectural extensions. Only. These are not the names of any implementations, nor of any platforms. Intel Itanium is the name of a family of microprocessor implementations of the Intel IA-64 architecture, as Intel Pentium and Xeon are the names of families of microprocessor implementations of Intel IA-32 and (potentially) of the EM64T extensions. I64 is the generic name for the various HP Integrity platforms supported by HP OpenVMS for Integrity Servers (and more commonly as "OpenVMS I64"); for the platforms supported by OpenVMS I64. (For additional related terminology, please see Section 14.4.5.) _____________________________ 2.3.1 How do I port from VMS to OpenVMS? You already did. Wasn't that easy? Please see Section 2.2 for details. __________________________________________________________ 2.4 Which is better, OpenVMS or UNIX? This question comes up periodically, usually asked by new subscribers and new posters who are long-time UNIX or Linux users. Sometimes, the question is ignored totally; other times, it leads to a long series of repetitive messages that convince no one and usually carry little if any new information. Please do everyone a favor and avoid re-starting this perpetual, fruitless debate. That said, OpenVMS and the better implementations of UNIX are all fine operating systems, each with its strengths and weaknesses. If you're in a position where you need to choose, select the one that best fits your own requirements, considering, for example, 2-4 General Information whether or not the layered products or specific OS features you want are available, and considering the expected cost-of-ownership over the lifetime of the system installation. If you are asking this question, you are probably comparing OpenVMS to UNIX. It was once certainly true that OpenVMS and UNIX were quite different. In more recent times, there are tools and C APIs on OpenVMS that directly provide or that easily support porting UNIX programs and commands, and there are equivalent packages bringing various OpenVMS features and mechanisms to UNIX platforms. If you seek UNIX tools on OpenVMS rather than the more philosophical discussion found in this section, please see the GNV package and other GNU discussions in Section 13.2.6, and please see the plethora of C calls currently available in the HP C Run-Time Library documentation, briefly discussed over in Section 13.2.1. __________________________________________________________ 2.5 Is HP continuing funding and support for OpenVMS? Yes. Active development of new OpenVMS releases is underway, as well as the continuation of support. Please see the following URLs for details, roadmaps, and related information: o http://www.hp.com/go/openvms/ __________________________________________________________ 2.6 What OpenVMS distribution kits are available? Various distributions are available. For the most current information on the available part numbers and current products (OpenVMS distribution kits, media, documentation, etc) and the most current associated licensing information, please see the current OpenVMS Software Product Description (SPD) document, available at: o http://h18000.www1.hp.com/info/spd/ 2-5 General Information OpenVMS typically uses SPD 25.01.xx, SPD 41.87.xx, and SPD 82.35.xx.

HP customers with commercial licenses and support contracts can download software product distribution kits from the following HP website: o http://www1.sqp.com/ You can also find pointers to the Software Rollout Report and to the OpenVMS SPD listings via the above SQP website. Information on obtaining and transfering licenses is available in Section 2.6 and Section 2.8.4, while information on the OpenVMS Hobbyist licensing program and on obtaining hobbyist product distribution kits is in Section 2.8.1. __________________________________________________________ 2.7 In what language is OpenVMS written? OpenVMS is written in a wide variety of languages. In no particular order, OpenVMS components are implemented using Bliss, Macro, Ada, PLI, VAX and DEC C, Fortran, UIL, VAX and Alpha SDL, Pascal, MDL, DEC C++, DCL, Message, and Document. And this is certainly not a complete list. However, the rumor is NOT true that an attempt was made to write pieces of OpenVMS in every supported language so that the Run-Time Libraries 2-8 General Information could not be unbundled. (APL, BASIC, COBOL and RPG are just some of the languages NOT represented!) There are a large variety of small and not-so-small tools and DCL command procedures that are used as part of the OpenVMS build, and a source code control system capable of maintaining over a hundred thousand source files across multiple parallel development projects, and overlapping releases. __________________________________________________________ 2.8 Obtaining and Transfering OpenVMS licenses? The following sections describe hobbyist and educational license programs, as well as information on commercial licenses and transfers. For information on the available commercial OpenVMS licenses and for information on license transfers, please see Section 2.8.4. OpenVMS Hobbyist licenses are discussed in Section 2.8.1. For information on the licensing implementation, troubleshooting licensing problems, on the License Unit Requirements Table (LURT), and other related details, please see Section 5.39. For configuring and troubleshooting LMF, see Section 12.4. _____________________________ 2.8.1 Questions asked by Hobbyist OpenVMS licensees? If you are a member of an HP-recognized user group (eg: Encompass, Enterex, DECUS), and are considering acquiring and using a VAX, Alpha or (soon) IA-64 system for hobbyist (non-commercial) use, (free) license product authorization keys (PAKs) for OpenVMS VAX, OpenVMS Alpha, and (reportedly) OpenVMS I64, and layered products are available. In addition to the license keys, OpenVMS VAX and Alpha distribution CD-ROM distribution kits are available with OpenVMS, DECwindows Motif, DECnet and TCP/IP networking, compilers, and a variety of layered products. (A hobbyist distribution for OpenVMS I64 is expected.) (While the hobbyist CD- ROM distributions are intended for and tailored for OpenVMS Hobbyists, the contents and capabilities of the 2-9 General Information Hobbyist installation kits included within the OpenVMS Hobbyist distribution do not differ from the standard distribution installation kits. The products are chosen to reflect the most popular products and the space available on the media.) If you have questions on what else is authorized by the license agreement and on what other distribution media is available to you, well, please read the applicable software license agreement(s). For further information, please link to: o http://www.openvmshobbyist.org/ On the OpenVMS Hobbyist license registration form at the above website (as of August 2005), you are offered the choice of the "OpenVMS VAX" license(s), the "OpenVMS Alpha" license(s), and the "Layered Products" licenses. You will want the operating system license for your particular OpenVMS platform and you will want the "Layered Products" licenses. You will want to select and to acquire two sets of license PAKs. For vendors wishing to license products specifically for hobbyist use (and to not issue hobbyist PAKs), the program provides hobbyists with the license PAK OPENVMS-HOBBYIST. If you plan to use a hardware emulator (eg: VAX emulator) on a Microsoft Windows platform, make sure you have an OpenVMS distribution kit that can be installed and/or booted with the particular emulator package you plan to use. For additional information on emulators, please see Section 13.12 and particularly please see the emulator-related documentation. _____________________________ Vendors offering Hobbyist Licenses o GrayMatter Software http://www.graysoft.com/GSCHobbyPR.html http://www.graysoft.com/GSCHobbyPR.html o Argent Software http://jams.argent-software.com/hobby.html 2-10 General Information o Kednos http://www.kednos.com/ o LJK http://ljk.com o Process Software http://www.process.com/openvms/hobbyist.html o Raxco http://www.raxco.com/hobbyist/ o Software Resources International (SRI) http://www.softresint.com/charon-vax/Tools_and_ tips.htm Hobbyist license product additions, and any updates for products already listed here are welcome.

For information on the hobbyist license program, please see Section 2.8.1. __________________________________________________________ 2.9 Does OpenVMS support the Euro currency symbol? OpenVMS can generate the %xA4 character code used for the Euro, and the DECwindows DECterm can display the glyph. Please check with the vendor of your terminal or terminal emulator for additional details. __________________________________________________________ 2.10 OpenVMS Ports? Itanium? Ports to IA-32, EM64T or AMD64 systems? OpenVMS has been ported to and is operational on four architectures: VAX, Alpha, IA-64, and IA-32. The first three have available native ports of OpenVMS, the fourth is available via emulation. VAX is the oldest architecture, and limited to 32-bit virtual and up to 34-bit physical addressing. The Alpha and IA-64 architectures are both 64-bit architectures, with 64-bit virtual addressing available. The available IA-32 emulation is provided for the OpenVMS VAX and other VAX operating systems, and provides a 32-bit VAX environment. For additional information on the emulation, please see Section 13.12. As for (the lack of) a native port for IA-32, OpenVMS Engineering presently and continues to believe that there would be insufficient market (read: profit, customer interest) to justify the cost involved in a native port of OpenVMS to systems using the Intel IA-32 architecture. In addition to the direct costs involved in any port and in addition to the substantial effort involved in moving backwards from a 64-bit 2-12 General Information environment on Alpha and on IA-64 to a 32-bit platform (such as IA-32), and the exceedingly non-trivial device qualification costs and the costs in moving backwards into older PCI and I/O environments (IA-32 systems more than a few years old have equivalently aged I/O support and buses), each organization and each person maintaining a product or a package for OpenVMS will have to justify a port to "OpenVMS IA-32", "OpenVMS EM64T" or "OpenVMS AMD64", akin to the decisions and the effort involved in porting a product from OpenVMS VAX to OpenVMS Alpha, or the port to OpenVMS I64. Platform ports of many of the various products can be easy, and many of the ports of applications using documented OpenVMS features are expected to require little more than a source rebuild. Other products can and do depend on platform-specific or undocumented features, and the associated ports can be more involved. Regardless, ports of operating systems are very large and involved projects. The prerequisite product requirements for an OpenVMS operating system port are also non-trivial, as well-compilers in particular are obviously required, and the suite of compilers provided must maintain a very high degree of source-level compatibility across the platforms. In the case of the HP Integrity port, OpenVMS I64 V8.0 used cross-compilers and cross-tools operating on OpenVMS Alpha systems, while V8.2 and later have various native compilers available. The OpenVMS I64 port was centrally built using the existing OpenVMS Alpha environment and around the work and the knowledge from the OpenVMS Alpha port, and OpenVMS Engineering fully expects that customers and ISVs will use and will continue to use OpenVMS Alpha systems to assist with their own ports to OpenVMS I64. OpenVMS Engineering fully expects to see customers using mixed-architecture clusters and fully shared file systems, as well. OpenVMS Engineering is well aware of the AMD AMD64 (64-bit) platform and processors. (At least one of the available VAX emulators can reportedly utilize parts of the AMD64 instruction set, please contact the VAX 2-13 General Information emulator vendor(s) or maintainer(s) for assistance and details on their products.) OpenVMS Engineering is also well aware of the Intel EM64T platform and processors. There are no plans to provide a native port of HP OpenVMS for any systems based on the AMD AMD64 nor Intel EM64T architectures. As part of the work leading to the Itanium port, senior engineers had extensively evaluated the products and the architectures available across the high-end 64-bit computing space, and chose to target Itanium for 64-bit environments-this while under the Compaq organization. This included looking at IA-32. HP (a co-developer of Itanium with Intel) had seperately chosen to target Intel Itanium for its high-end computer products. Compaq then announced plans for the future of Alpha through EV7-series products and platforms, and HP (entirely seperately) announced plans for PA-RISC products and platforms. The Itanium target has been maintained consistently since the Itanium port was announced by Compaq, and has also been consistently maintained by HP and by the combined company. For those folks prefering to follow the schedules and the product deliveries, OpenVMS Engineering had OpenVMS I64 V8.0 ready (internally) ahead of schedule-and with more features available within the release than had been originally planned for the release. (For information on and for schedules of future OpenVMS releases, please see the roadmap that is available at the OpenVMS website.) OpenVMS I64 itself does not require and does not plan to utilize the Itanium IA-32 32-bit environment for the operation of OpenVMS itself. OpenVMS I64 V8.0 and later run natively on the Itanium processor family, with no use of IA-32 instructions. While OpenVMS can and does support 32-bit OpenVMS applications and addressing on Itanium, this is done with sign- extension addressing techniques entirely analogous to what was done with 32-bit applications operating in the 64-bit Alpha environment. Both OpenVMS 32-bit and 64-bit applications operate within the native Itanium instruction set and run-time environment, and do not use the Itanium IA-32 environment. 2-14 General Information But yes, a native IA-32 port or a native AMD AMD64 or Intel EM64T port of OpenVMS would certainly be nice to have-this, of course, following the traditional Linux preference for having a Linux port available for most (all?) computer architectures known, and even for certain high-end refrigerators and toasters, and similar appliance-like devices. (The downside of this all-encompassing approach: this requires near-infinite engineering and support costs from the various vendors involved, and the qualification efforts and costs of most everything-everywhere. Or reduced or eliminated testing and support efforts. Or an unfortunate combination of these two. These costs are huge, and the benefits derived from the work are comparatively small when given the comparable costs of more targeted (and thus supported and supportable) hardware configurations-the platform targets are and must be carefully selected and considered by each vendor. Put another way, there are no plans to provide a native port of HP OpenVMS for systems based on Intel IA-32 processors, nor for systems based on AMD AMD64 nor Intel EM64T architectures and processors. All this material having been written, have you looked at the system configurations and pricing of the available HP Integrity Intel Itanium systems? Low- end computer hardware is clearly a commodity product, and the systems are priced, serviced, upgraded, and replaced accordingly. Intel Itanium is a commodity microprocessor presently used in platforms available from various hardware vendors, including (obviously) from HP. Further, Itanium is a microprocessor available from and supported by Intel, a semiconductor vendor known for exceedingly high-volume microprocessor fabrication process and production capabilities. For information on supported platforms and processors, please see the OpenVMS Software Product Description (SPD) at: o http://h18000.www1.hp.com/info/spd/ OpenVMS typically uses SPD 25.01.xx, SPD 41.87.xx, and SPD 82.35.xx. 2-15 General Information Please see Section 14.4.5 for Intel Itanium terminology. __________________________________________________________ 2.11 Are there any network-accessible OpenVMS systems?

Porting can range from simple to rather complex, and depends on the features used on the original platform. This section covers generic porting, and porting among OpenVMS VAX OpenVMS Alpha, and OpenVMS I64. (Porting among OpenVMS VAX, OpenVMS Alpha and OpenVMS I64 is often quite simple and involves little more than rebuilding from source, though a few applications using features specific to the platform or the architecture, or using undocumented or unsupported interfaces can and likely will require some additional effort to port.) Several manuals on porting from OpenVMS VAX to OpenVMS Alpha are available in the OpenVMS documentation set, including information on porting VAX Macro32 assembler code to the Macro32 compiler on OpenVMS Alpha, on management differences, on upgrading privileged code, and application migration: o http://www.hp.com/go/openvms/doc/ Documentation on porting to OpenVMS I64 is available, as well.

Please see other sections of this FAQ, and please see: o http://www.hp.com/go/dspp_catalog __________________________________________________________ 2.15 What resources are available to OpenVMS software developers? The HP Developer and Software Product Partner (DSPP) program is open to and intended to support and to assist HP OpenVMS software partners, consultants, and service providers: o http://www.hp.com/dspp/ DSPP provides members with various benefits, please see the website for details. 2-20 General Information For those not familiar with the DSPP program or with its history, the DIGITAL Association of Software and Application Partners (ASAP) program and the DIGITAL Independent Software Vendors Network (ISVN) program were incorporated into the Compaq CSA program, and the CSA program has subsequently been incorporated into the HP DSPP program. Please see Section 2.8.3 for additional details on the DSPP program. __________________________________________________________ 2.16 memory management, resource management, process scheduling, etc? So you have been instructed to write a school research paper on OpenVMS, and you need technical content on the OpenVMS Virtual Memory System, on any memory segmentation, on OpenVMS Resource Management, on the OpenVMS File System, on the OpenVMS user interface, etc. Invariably, your professor/instructor/teacher will ask you a series of questions. Most commonly, the questions will request descriptions of one or more of the following items, and at varying levels of detail: o process scheduling algorithm(s) o Interprocess comunications o Process or system synchronization constructs o Memory management and/or virtual memory implementation o RMS or XQP file structures o Resource management o History of HP OpenVMS o History of Compaq and/or of Digital Equipment Corporation (DEC) 2-21 General Information Any particular presentation or research paper, and particularly a scholastic presentation, can have many different potential target audiences, and very different presentation levels. Further, the usual underlying reason for scholastic presentations and scholastic research projects really has little to do with the subject matter, it is a task specifically intended to teach the student(s) (eg: you) how to perform the research. The instructor already knows most of (all of?) the information that you have been asked to collect. For very technical details on OpenVMS and OpenVMS internals, the book you want is the Internals and Data Structures Manual (IDSM), available in your school or computing center library, and the IDSM can also be purchased. Additional technical details of the Alpha microprocessor are available in the Alpha Architecture Reference Manual documentation that is available for download. (Pointers to Alpha technical documentation are available in Section 14.6, and elsewhere.) For higher-level (less technical) details, the OpenVMS documentation set is available on-line. The Programming Concepts and the File Systems manual are probably the best manuals to start with, depending on the particular level of detail the research requires. And please understand the hesitation of various folks to provide you with a completely-written research report on your topic. Why? We might have to work with you after you graduate-you need to know how to perform at least basic research on your own, regardless of the topic. __________________________________________________________ 2.17 Basic Units of Measurement? OpenVMS and the underlying hardware use various units of measurement for disk and memory storage, and related abbreviations also typically exist. This section covers the most common units, and the associated abbreviations. 2-22 General Information _____________________________ 2.17.1 How many bytes are in a disk block? A disk block is the minimum unit of disk storage allocation in OpenVMS. Under OpenVMS VAX and OpenVMS Alpha, the disk volume block size is consistent, with each block containing 512 bytes. The minimum disk allocation granularity actually permissible (in the ODS-2 and ODS-5 volume structures commonly used on OpenVMS) is determined on a per-volume basis, and is typically based on a combination of the total number blocks on the disk volume and the total size of the volume storage bitmap. The allocation granularity is known as the volume cluster factor- the cluster factor is the number of blocks in a disk cluster, and it is the smallest number of blocks that can be allocated on a particular disk volume. Prior to OpenVMS V7.2, the maximum permissible size of the bitmap requires larger cluster factors as volume sizes increase. Starting with V7.2, the bitmap can be larger, and cluster factors as small as one block can be used. The number of bytes in a file can be determined by multiplying the number of blocks allocated for the file times the number of bytes in a block. For sequential files (only), the FFB (XAB$W_FFB, in the File Header XAB) value can be used to find out how much of the last (XAB$L_EBK) block is used. FFB and EBK are meaningful only for sequential files, and only in a limited context-partial block allocations are not permitted. For other file formats, the EOF marker is not meaningful. Disk allocations always occur only in units of the cluster factors, which can be from one block up to (potentially) clusters of eighteen blocks or more, depending on the volume cluster factor. (OpenVMS V7.2 and later optionally provide for a cluster factor of one up to volumes of approximately 137 gigabytes.) 2-23 General Information OpenVMS assumes that the device driver and the underlying storage device will present the file system with addressable units of storage of 512 bytes in size, or the appearance of same. Various third-party CD-ROM devices, for instance, support only 2048 byte blocks, and such devices are incompatible with the standard OpenVMS device drivers. To determine the number of bytes required for a file from DCL, one option uses the f$file_attributes item EOF, multiplied by the size of a block in bytes (512). This does not account for the unused space in the last block of a sequential file, but it also does not have to differentiate sequential files from other files. _____________________________ 2.17.2 How many bytes are in a memory page? A memory page is the minimum unit of memory allocation in OpenVMS. With OpenVMS VAX, the memory page size matches the disk block size: it is always 512 bytes. With OpenVMS Alpha, the memory page size is variable, and it can range from 8192 bytes (8 kilobytes) up to 64 kilobytes. The current system page size can be determined using the sys$getsyi or f$getsyi PAGE_SIZE item. Programs with hardcoded constants for the memory page size (or page alignment) should always assume a page size of 64 kilobytes. On OpenVMS I64, the memory page size is also variable, ranging from 4096 bytes (4 kilobytes) up to 256 megabytes (MB) and potentially up to 4 gigabytes (GB). As with OpenVMS Alpha, sys$getsyi and f$getsyi and the PAGE_SIZE itemcode can and should be used to determine the current system page size. In general, OpenVMS I64 will use a page size of 8 kilobytes, or larger. On OpenVMS Alpha and on OpenVMS I64, a 512 byte area of memory- equivalent in size to an OpenVMS VAX memory page-is often refered to as a "pagelet". 2-24 General Information _____________________________ 2.17.3 How do I convert? Disk Blocks? KB, MB, GB, TB? The smallest granularity of disk storage addressing is called a disk block, or sometimes a disk sector. Groups of disk blocks are usually organized together into the smallest unit of storage that can be allocated, and this unit is called a disk cluster. The number of blocks in a cluster is the cluster factor, and is established when the disk volume is initialized. Each individual disk block is composed of five hundred twelve (512) bytes, or one-half kilobyte. Each byte is comprised of eight bits. A bit represents the smallest unit of information, typically refered to as a one or a zero. OpenVMS tends to uses base two notation for disk storage, while disk storage capacity specifications from most storage vendors will generally use base ten notation. An OpenVMS disk block is 512 bytes in size; this is one-half kilobyte in base two notation. The following table describes the prefix, the abbreviation, and the associated base ten (as used by marketing and by storage vendors) and base two (OpenVMS and various other operating systems) values. Base Ten Base Two -------------------------------- ------------------------- Kilobyte (KB) 10**3 1000 2**10 1024 Megabyte (MB) 10**6 1000000 2**20 1048576 Gigabyte (GB) 10**9 1000000000 2**30 1073741824 Terabyte (TB) 10**12 1000000000000 2**40 1099511627776 Petabyte (PB) 10**15 1000000000000000 2**50 1125899906842624 Exabyte (EB) 10**18 1000000000000000000 2**60 1152921504606846976 The base ten representation of the 2**40 value is 1099511627776, which is obviously rather ugly. When viewed as a base eight or base sixteen (octal or hexadecimal, respectively) value, the value is far nicer. Specifically, the value is 10000000000 and 40000000 when represented in octal and hexadecimal, respectively. 2-25 General Information FAQ Notation Within the OpenVMS FAQ, a thousand bits (either assuming base two or base ten, as determined by the context) is refered to as a kilobit, and is always represented by the appreviation Kb, while a thousand bytes is refered to as a kilobyte and is always abbreviated as KB. Similar notational usage also holds for Megabits (Mb) and Megabytes (MB), and for the various other units. OpenVMS operating system references to system and storage are generally to the base-two version (eg: 1024, in the case of a kilobyte or kilobit) while storage hardware references and hardware specifications are generally to the base-ten version (eg: 1000). To convert OpenVMS disk blocks to (base two) kilobytes (KB; 1024 bytes), simply divide by two. To convert blocks to (base two) megabytes, divide by 2048. Blocks to (base two) gigabytes (GB), divide by 2097152. These particular divisions can also be performed using bitshifts: to divide a value by two, shift the binary value rightward by one bit position. To convert OpenVMS disk blocks to (base ten) kilobytes, divide by approximately 1.953125. For those folks with an interest in odd applications for prefixes, and particularly for those folks also rummaging around deep within the OpenVMS operating system, a microfortnight is approximately one second. 2-26 _______________________________________________________ 3 Documentation __________________________________________________________ 3.1 Where can I find online copies of OpenVMS manuals? The HP OpenVMS and HP Layered Product documentation is copyrighted material. HTML format on-line product documentation sets for specific HP OpenVMS products are presently available at: o http://www.hp.com/go/openvms/doc/ Documentation is offered on separately orderable CD-ROM media through a subscription to the Consolidated On- Line Documentation (ConOLD) product (see Section 2.6.) ConOLD manuals are readable with BNU, a viewer that is supplied with the documentation distribution. BNU can display HTML, Bookreader, and documentation in other formats. MGBOOK, a viewer for Bookreader-format documentation is available for character-cell terminals (eg. VTxxx) via the WKU VMS Freeware file server - see question Section 13.1 for details. Information on the XPDF DECwindows PDF viewer for OpenVMS is available in Section 13.1, and XPDF kits are available on various Freeware distributions.

The OpenVMS Internals and Data Structure manual (IDSM) explains how the OpenVMS executive works. The book covers the operating system kernel: process management; memory management; the I/O subsystem; and the mechanisms that transfer control to, from, and among these. It gives an overview of a particular area of the system, followed by descriptions of the data structures related to that area and details of the code that implements the area. 3-5 Documentation The first edition of the OpenVMS Alpha internals book describes Version 1.5. Although there have been several releases of OpenVMS Alpha since Version 1.5 (V6.1, V6.2, V7.0, V7.1, etc) and many details in the book are no longer accurate, it continues to provide a strong conceptual description of OpenVMS internals. This book has been split into five pieces, each to be updated separately. The first such volume, published in early 1997, was "OpenVMS Alpha Internals and Data Structures: Scheduling and Process Control," which covers the Version 7.0 implementation of true multithreading and the changed scheduling model it implies. The internals books are available through Digital Press, see Section 3.6 __________________________________________________________ 3.6 Where can new users find tutorial information about OpenVMS? First, see if your local site has information on this topic. Each site can have site-specific features and configuration. Some sites will have site-specific new user's documentation, covering various site-specific things that are difficult or impossible for the general OpenVMS documentation to cover. _____________________________ 3.6.1 Tutorial Websites?
