Welcome to the Info-Stratus mailing list and newsgroup "comp.sys.stratus". This is a periodic message, last updated during 1998. It contains answers to some Frequently Asked Questions. Due to prevailing social conditions on the Internet, and to keep unwanted email messages from bothering people who have better things to do, I have made a systematic character substitution in all email addresses in this message. Anywhere you see a construct that looks like this: , before you send mail to it, you must substitute the commercial "at" symbol, so that it becomes . (The email addresses are also enclosed in angle brackets, as they may appear according to the Internet mail-header standard RFC-822. If your email program thinks that the addresses are badly formatted Web hyperlinks and hides them, you should look for an email program that does not try so hard to be clever.) ...Richard S. Shuford Info-Stratus List Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Stratus Computer, Inc., of Marlboro, Massachusetts, USA, makes and sells "Continuous Processing" transparently fault-tolerant computer systems. The pair-and-partner hardware architecture of the Stratus machines provides complete transparency in fault tolerance. If some hardware component fails, the application programs need NEVER become aware of it. The machine does NOT have to execute a "fail-over" script. No processes have to be re-started; no transactions have to be rolled back. Processing just keeps going as if nothing had happened. The still-operating computer can be remotely diagnosed by service personnel, and new replacement parts can be installed--without rebooting the machine, without downtime. Several different operating systems and software environments are found on various Stratus hardware, including VOS, FTX, Pick, HP/UX, and Windows-NT. ...- --- ... ...- --- ... ...- --- ... ...- --- ... ...- --- ... VV VV OOOOO SSSSS VV VV OO OO SS VV VV OO OO SSSS VVV OO OO SS V OOOOO SSSSS The original operating system developed for Stratus hardware was VOS. This is still a popular choice of many Stratus customers, and a basic description is available on the Internet Worldwide Web at the location pointed to by this Uniform Resource Locator (URL): http://www.stratus.com/cont/S600/p4.html VOS was designed from its inception as a high-security transaction- processing environment tailored to Fault-Tolerant hardware. It incorporates much of the design experience that came out of the famous MIT/Bell-Laboratories/General-Electric (later Honeywell) MULTICS project. Read about MULTICS from here: ftp://ftp.stratus.com/pub/vos/multics/multics.html (MULTICS pioneered some operating-system features we now take for granted, including the idea of writing the OS in a high-level language, hierarchical tree-structured directories, and access rings. The very word "Unix" is a kind of pun on MULTICS.) Along with its internal features, VOS supports a very large number of communication protocols. You may never encounter some of them, but somewhere in the world people do need VOS to speak "Airline Link Control", "Poll/Select", and "Datakit". If you are a complete newcomer to VOS, as long as you don't expect VOS to appear identical to some other operating system, you will probably find that it "does the right thing" for you and that its command structure is straightforward. For instance, the command to copy a file is "copy_file", and the command to show you a list of files is simply "list". Here are a few hints that may make your life easier: (1) VOS commands usually have a form-based interface for initial user input, which is supplemented by a "lineal" command form. The options for any command may be made visible by using the "-form" or "-usage" arguments. If you don't know which key on your keyboard invokes the form, you can still see what the form looks like by using both together: display -usage -form (2) An approximation to an "apropos" or "man -k" function is the construct help -match 'keyword' (3) If your terminal type is set wrong, and you are using a Televideo-955-compatible emulator, try set_terminal_parameters -terminal_type 'v103_ascii' Other supported types include ibm3161, vt100, vt320, and cac_xterm. Most Stratus asynchronous serial ports will default to odd parity. (4) Some terminal types define a "help" key, which can sometimes lead to greater knowledge, but eventually you'll need the real documentation. The publications "VOS Commands User's Guide" (for releases through 12) or "VOS Commands Reference Manual" (13 and up) are good places to start. (5) In VOS EMACS, Escape-P and Escape-N are previous- and next-page keys. (6) Be on friendly terms with your underscore key. If you can't use the Cancel key to stop a program, Control-C often stops programs. (7) The test_system_calls facility is handy in trying out certain system functions. (8) Learn to use the standard abbreviations and make your own for frequent activities. Remember that commands are case-sensitive. A compilation of advice gleaned from past Info-Stratus discussions resides at: ftp://ftp.stratus.com/pub/vos/doc/answers/ The files in the above directory contain attempts to answer many recurring, specific "how do I do X?" questions. Even if you are not satisfied with the answers, they can provide you with background to ask informed questions. Another source of information about VOS is the cumulative CAC Newsletters: look for these on your VOS system in this directory: (master_disk)>system>doc Although the information in some newsletters is rather old, they should be available on most VOS modules (at least they are installed by default along with the operating system). If they are missing from your system, you can also get them via the Internet from the Stratus FTP site: ftp://ftp.stratus.com/pub/cac/newsletters/ Definitions of terms may be found here: ftp://ftp.stratus.com/pub/vos/doc/reference/glossary.txt - - - - - - - - - - - - Many questions asked in Info-Stratus are of the form: "In Unix, I like to use tool XYZ. Is XYZ available under VOS?" Please do not suppose that all good software ideas come out of Unix. I wish that somebody would create a Unix equivalent to the VOS service s$parse_command() to alleviate argc/argv programming tedium and make life easier for the end user. getopt() isn't even close. Many popular software tools have been ported to VOS over the past several years. Last year, the collection on the FTP server at "ftp.stratus.com" was augmented with some long-requested items. For an overview of the holdings on that server, point a Web browser at this Uniform Resource Locator (URL): ftp://ftp.stratus.com/pub/vos/vos.html Paul Green has essentially completed a project to bring the greater part of the standardized POSIX computing environment to VOS. The "alpha-test" versions of his POSIX package may currently be found in: ftp://ftp.stratus.com/pub/vos/alpha/alpha.html This POSIX collection contains a preliminary version of Perl 5.004. After many requests, a "vi"-like editor for VOS has appeared on the scene. Now VOS users can enjoy the famous "insert" and "beep" modes! Leo Zvenyatsky has ported "stevie", a work-alike clone of the BSD Unix "vi" editor, to VOS. Also, the "elvis" vi work-alike (written by Steve Kirkendall) has become available for VOS, thanks to Joseph Felder. These "vi" workalikes, plus the 4.x version of Larry Wall's legendary "Perl" language/utility processor for VOS, are available from the selection at this URL: ftp://ftp.stratus.com/pub/vos/tools/tools.html In the VOS tools collection, you'll also find the "grep" utility and "lpr" for Berkeley-Unix-style printing. A version of cron is now available, although the VOS "batch" facility can do most of what people do with cron in Unix. ---- The files you retrieve must be unwrapped from three layers of packing before you can start compiling, so read these instructions: ftp://ftp.stratus.com/pub/vos/utility/README.txt ftp://ftp.stratus.com/pub/vos/tools/stevie.txt The "PACKAGENAME.save.evf.gz" files are compressed bundles created by the "bundle" and GZIP tools in ftp://ftp.stratus.com/pub/vos/utility/ When transferring a ".pm" executable file to a VOS system, try to login to the VOS module and use the VOS "ftp" client program to "pull" the file, rather than pushing it from a PC client program. Before issuing the "get" command, give this command to the VOS ftp client: ftp> type image 4096 then you can safely do ftp> get gzip.860.pm (or whatever is appropriate) (NOTE: gzip is more akin to the Unix "compress" program than to PKzip.) >>> As with all of this user-contributed software, >>> don't expect any official support from Stratus. >>> But you can ask questions to the readers of >>> Info-Stratus and "comp.sys.stratus". Information on how to use some of the above software: If you want to learn Perl, look to the llama: http://www.ora.com/catalog/lperl/noframes.html or to the camel: http://www.ora.com/catalog/pperl2/excerpt/ch01-01.htm Some have asked for a VOS "curses". For those that cannot use the native "ttp" facility, the proper approach is to explore the task of porting the new "ncurses" library to VOS. This package, developed by Zeyd Ben-Halim, Eric Raymond, and T. E. Dickey, is a freeware emulation of System V Release 4.0 curses. Source may be obtained by anonymous FTP via this URL: http://www.clark.net/pub/dickey/ncurses/ncurses.html Since VOS version 10.5, Stratus's OS-TCP/IP product provides implementations of the ever-popular TCP/IP applications "telnet" and "ftp". OS-TCP is the underlying transport mechanism for Open StrataLink and Open StrataNet. (The product "TCP2" is the older TCP/IP Release 2 protocol stack, which supported fewer features and which is being phased out.) A VOS NFS Server product for OS-TCP (S0135Vxxxx) is available from Stratus, which has a popular accessory packaged with it: a full RPC (Remote Procedure Call) library. Jim Richey has devised an NFS Client that works with the older TCP2 Release. Note that this client does NOT work with OS TCP/IP and is unsupported by Stratus. But it may be useful in some situations, so you can have a look at these two URLs: ftp://ftp.stratus.com/pub/vos/tools/nfs.txt ftp://ftp.stratus.com/pub/vos/tools/nfs.save.evf.gz A means of sharing a Windows-95 or NT PC's disks with a Stratus module using Open StrataLink (over Ethernet) has been devised by Dave Durant. This is NOT officially supported (nor are PC disk drives anything like fault-tolerant!), but some may find it useful: ftp://ftp.stratus.com/pub/vos/tools/pc_osl.txt ftp://ftp.stratus.com/pub/vos/tools/pc_osl.save.evf.gz Dave Durant has also released a Usenet news reader for VOS, which accesses a remote NNTP server. ftp://ftp.stratus.com/pub/vos/tools/read_news.save.evf.gz For sharing Stratus disk resources with Windows platforms via the SMB (Microsoft LANmanager) protocol, Erik Devriendt adapted the Samba program to run under VOS: ftp://ftp.stratus.com/pub/vos/tools/samba.txt ftp://ftp.stratus.com/pub/vos/tools/samba.save.evf.gz A general overview of Samba may be viewed at http://samba.canberra.edu.au/pub/samba/ At least two different version/configuration-control products are commercially available for VOS, but a simple "make" program is now freely available, thanks to Dave Thomas and Paul Roub. The source code in C may be obtained via anonymous FTP via this URL: ftp://ftp.stratus.com/pub/vos/tools/make.save.evf.gz Thanks to Grapevine Systems, there is now a port of GNU RCS (Revision Control System) for VOS: ftp://ftp.stratus.com/pub/vos/tools/rcs.save.evf.gz (There also exist several commercial products for VOS configuration control.) Version 6.0 of C-Kermit from Columbia University fully supports VOS, thanks to the efforts of David Lane and Kernie Brashier. This mature and versatile protocol implementation boasts features such as command completion, file-transfer recovery from point of failure binary-mode transfers only), support for TCP/IP, etc. Support for long packets and sliding windows can speed up Kermit transfers to within 2% of Zmodem's rate. Another nice feature is session scripting, which allows you to automate the interactions of a "telnet" session from within Kermit. (The recent prebuilt verions supposedly include the patch allowing C-Kermit to work from a window_term telnet session.) Connect using anonymous FTP to "ftp://kermit.columbia.edu/kermit/f/" to obtain C-Kermit either in source code form (in C) or as pre-built executable images (encoded to printable characters for transfer) for HP PA-RISC, Intel RISC, or Motorola-CISC-processor VOS machines. Be sure to read the file "cklker.bwr" which contains special instructions for VOS users. The full C-Kermit documentation is the book "Using C-Kermit" by Frank da Cruz and Christine M. Gianone, (Digital Press/Butterworth-Heinemann, ISBN 1-55558-108-0). See these three URLs: http://www.columbia.edu/kermit/manuals.html#ckb http://www.columbia.edu/kermit/newsn6.html#vos http://www.columbia.edu/kermit/ckermit.html (I personally bought this book; it contains very clear explanations, not only of how to use Kermit, but also of many general concepts in data communication.) As of this writing, release 6.1 of C-Kermit 6.1 is being adapted to VOS. >>> One "frequently asked question" asks for a VOS version of the >>> "Zmodem" file-transfer protocol. I know of at least one consultant who sponsored a port of Zmodem to VOS, but so far no one has advertised having such software available for sale. This is probably because of the terms under which Zmodem is licensed from its owner, Omen Technology. You can obtain information on how to purchase source code of existing versions by sending email to . [climb on soapbox] In the meantime, C-Kermit works quite well, and the Kermit protocol is more robust than Zmodem in the complex communication environments in which Stratus machines are often found. And if you set the tuning parameters correctly, the speed of Kermit's file transfer can be within 2 percent of zmodem's best speed. (Quite frankly, I am annoyed with the people who write user manuals for modems; without really looking into the details, they parrot the old assumption that Kermit transfers must be slow. Megahertz is one modem vendor employing parrots.) [climb down] But if you need to use the older "xmodem" protocol, you can find a VOS implementation at: ftp://ftp.stratus.com/pub/vos/tools/xmodem.save.evf.gz There is also an implementation of "ymodem" in the Async Gateway product of Knowledge Systems, Inc.

These are separate products that have somewhat different realms of usefulness. Most new software will probably be written with Standard C. With releases of VOS newer than 11.0, the interpretation of C-language syntax and usage by the compilers has become stricter. To make your programs robust, take heed of "os_errno". If you really would like to see Stratus provide a C++ compiler for VOS, send e-mail to to provide impetus. VOS releases since 12.0 allow log-protected files, for functionality similar to the Unix Veritas file system. Various third-party commercial vendors can supply a VOS site with an SNMP (Simple Network Management Protocol) agent, or a Worldwide Web HTTPD server package. At the present time, I am still maintaining a page of links to Stratus- related sites and pages on the Worldwide Web: access my links via this URL (Uniform Resource Locator): http://www.cs.utk.edu/~shuford/terminal/stratus.html (Among other things, I have links to vendors of PC terminal-emulation software who make some effort to support Stratus terminal types.)

I'm not an FTX expert, but the short answer is that FTX is derived from the AT&T System V Release 4 code, with some kernel modifications and a few enhanced features, such as symmetric multiprocessing. From the user's point of view, it should perform like any well behaved Unix, unless you ask it to do something Berkelish. (In general, in the Unix world, BSD releases are increasingly eclipsed by SVR4-flavor variants, which include Solaris 2.x, IRIX, and HP/UX. Even Linux is more like SVR4 than BSD.) FTX complies with the SVR4 interface definition (SVID3), XPG3, and POSIX, and has been entered into the X/Open Unix Branding program. The Veritas log-based file system (VxFs) is incorporated into the FTX SVR4 virtual file system interface. An FTX system administrator can aid performance using several kernel tunable parameters. The X/Open status is announced from this URL: http://www.xopen.org/public/prods/stratus.htm Stratus Education offers course FTX-140 "Object Oriented Programming With C++". Call +1 508/481-9431 for details. The most recent release of FTX is described in this Worldwide Web page: http://www.stratus.com/cont/S600/p4.html and the server "ftp.stratus.com" has a section devoted to FTX files. There is an index page for your Web browser: ftp://ftp.stratus.com/pub/ftx/ftx.html Several popular but unsupported (by Stratus) tools for FTX are available from the FTP site, including the "top" system-monitoring utility, the zmodem file-transfer protocol (for i860), dbmalloc, and tcp_wrappers. ftp://ftp.stratus.com/pub/ftx/tools/ Custom files necessary for using gcc (the GNU C compiler) under FTX 3.x on PA-RISC are also found there. An FTX version of the Revision Control System (rcs) may be found in: ftp://ftp.stratus.com/pub/ftx/rcs/ GNU Emacs can be built under FTX after some tinkering with the configure script.

Issues not specific to operating system: A question sometimes arises about online documentation. The StrataDOC product is a workstation-based online documentation product, covering either FTX 3.x or VOS 13.x manuals on CD-ROM and featuring hypertext linking as well as full-text search and retrieval. StrataDOC requires (and supplies) a Framemaker reader on the supported platforms.. New manuals produced by Stratus are being adapted to HTML format for viewing with Web browsers. ____ ____ ____ Many items of documentation placed on the Stratus official FTP server are stored in one of the complex, proprietary data formats promulgated by Microsoft, such as Word-97 or PowerPoint. If you don't normally deal with such data formats, you may yet be able to read this documentation. Microsoft provides--for users of its Windows operating systems--a selection of free, read-only, document- viewing programs.

CM post trap: Post notify or if_loop: mbuf has insufficient offset 0 These are harmless indications of some internal consistency checking that VOS is doing. Don't worry about them. If your site has a current Stratus service contract, then you may be able to access the Stratus Problem Report Search Service using its Worldwide Web interface, StrataSearch. With StrataSearch, you can directly view the explanations for these messages (and investigate other topics of interest). (For instance, you can search for item "otp-622" to see discussion of the mbuf message.) Be aware that you must set up an "RSN connection" password with your CAC before you can access the StrataSearch database, and this password sometimes takes a day to go into effect when you first set it up. This is NOT the same as the RSN password used by Stratus personnel to dial in. ____ ____ ____ There are several other syserr_log messages occurring in some releases of VOS that are generally considered harmless. You can generally ignore these: Unable to delete fence for user Username.Group Ptep=XXXXXXXX 000000 Code=1409. IOP[4]: [#23] GCI: (15) PERTEC_TAPE: Out Mbx int from dev# 0 IOP[4]: [#24] GCI: (16) OUT_MBX: Command= -7, data_16_1=1800, data_32_1=000000 iop[6]: [#8570] SCAN: full pass of scanner 0 not complete, pbus_status ____ ____ ____ The following errors are benign from the standpoint of the operating system, but they may mean that an application program is addressing memory strangely. mercury_mm_util: Invalid L1 table entry. root=02025000 vpn=00080000 atlantic_mm_util: Invalid root table entry for VPN 000DE097. ____ ____ ____ In recent releases of VOS (13.3.3 and 14.0.x) on a Continuum module, an mnt-826 error may be seen at boot time, saying: CC: Incompatible partition sizes, using actual size expected size = 948 actual size = 232 This occurs when the ReCC boot_paths partition was last burned with the version 1 info structure. The condition is benign and should cause no problem, but reburning the ReCC will eliminate the reporting of the message. ____ ____ ____ Some persons perusing system-supplied include files ask why there are structure elements named "mbz". This is a short way to say "must be zero." ____ ____ ____ Some users of VOS Emacs would prefer that files contain literal tab characters. To change the behavior for the current buffer, type: Escape R set_mode literal_tab on To change the default behavior, put the following in your start_up.emacs file: execute_request set_mode default_literal_tab on To print a file containing tabs, do: print -interpret_tabs At startup, VOS Emacs reads only the first 50 lines of a file; if you want it to proceed to read the entire file, type Control-G as your first keystroke. .-.. .- --.- .-.. .- --.- .-.. .- --.- .-.. .- --.- .-.. .- --.- One general question is sometimes asked by users of ALL computers: "Oops! Is there a way I can UNdelete a file on my disk?" On a personal computer that has only one person ever using it--running Windows-95, MS-DOS, or MacOS, or--you may be able to get a happy answer. HOWEVER, all the Stratus operating systems are multi-user, multi-processing environments, where many processes and users are sharing the same set of disks. When a file is deleted, the disk blocks containing its data are immediately marked by the operating system as available for storing the data for some other, unrelated file. On a busy system, therefore, the data from your deleted file will almost surely be overwritten before you could try to recover it. And, for a large file, VOS frees up the indirect blocks that link it together. That's why Stratus does not distribute an "undelete" program; that's why it's important to perform tape backups even for mirrored disks. Two features of the VOS filesystem can help prevent disasters with particularly important files. The first is the "safety switch", which stops the delete_file command in its tracks: set_safety_switch start_up.cm on delete_file start_up.cm delete_file: Operation invalid while file is protected by the safety switch. The second possibility in VOS is to delay the possibility of deletion: set_expiration_date start_up.cm 98-12-31 delete_file start_up.cm delete_file: The object may not be deleted before its expiration date. In the Unix operating systems (FTX or HP-UX), you can use the file modes to lessen the vulnerability of inadvertently trashing a file: % chmod 444 .profile (You'll have to use different digits if setuid or sticky bits are involved.) Another Unix technique is to create a dummy file in each important directory that will trick the "rm" command into asking whether files should be deleted. Create it as follows: % touch ./-i -- .. ... -.-. -- .. ... -.-. -- .. ... -.-. -- .. ... -.-. -- .. ... -.-. Another question is: "We just hooked up a Stratus module to our existing Ethernet using a K104 adapter, and the throughput is really slow. What gives?" The Stratus K104 Ethernet adapter requires that you use the SQE (Signal Quality Error Test) signal on AUI connections. If you don't, the Stratus module will believe that network collisions are occurring with almost every packet and will continually reset the LANCE controller chip, with resultant poor performance. Some other computer and network vendors (Sun and cisco among them) play fast and loose with Ethernet SQE, so a network that seems to be OK--connecting other types of machines--can first show this problem only when you plug in the Stratus module. Have your Stratus Systems Engineer or a good Ethernet specialist check your network configuration. For more information about Ethernet, IEEE 802.3, and SQE, see: ftp://ftp.syr.edu/information/faqs/big-lan.faq (especially Q-22.) http://wwwhost.ots.utexas.edu/ethernet/ethernet-home.html (Twisted-pair Ethernet, as from the K460 BIO Ethernet ports, does not experience this SQE problem.) .-.. .- --.- .-.. .- --.- .-.. .- --.- .-.. .- --.- .-.. .- --.- .... .- .-. -.. .-- .- .-. . .... .- .-. -.. .-- .- .-. . .... .-- Stratus builds its computers using commonly available processors, aided by proprietary logic that implements the "pair-and-partner" fault tolerance.
