Mainframe utilities

Last update : 9 November 2003

The CBT tape

  • Naspa MVS library (CBT tape) is THE site for MVS Freeware : The CBT Tape Home Page. The access to Naspa MVS library is now restricted. Sam Golob gives recent information about the CBT tape.
  • Here are on my site the utilities that were the most useful for me :
  • Showmvs is a must have (you may run it in batch or call it directly from TSO). You can unload SHOWMVS from Gilbert Saint-flour's site. Gilbert is the original author of Showmvs, enlighted contributors are now Roland Schiradin and Jerry Morris.
  • REVIEW is great for displaying VSAM files, SMF files, etc. It is accessible via CBT Tape file 134.
  • A very handy disassembler is DISASM. Rebuild the zones and the code in no time. It is accessible via CBT Tape file 217.
  • Free PDS version 8.5 is a useful (although not for newbies) utility to do whatever you want on PDS files, it is available on http://members.aol.com/freepds.
  • Vtocutil version 2.2 to list and change Format-1 DSCB information for DASD volumes with Indexed VTOCs.
  • The best dynamic allocation program is DYNAM (on CBT089).

    Xephon

    Xephon archives are incredible ! There are hundreds of mainframe related articles and programs for free ! Some are of big interest, like this super scratch program, or this general purpose subroutine to manage VSAM files or routines for accessing cross-memory storage in REXX.

    SHARE

    SHARE organization is working on a "MVS cluster" that provides interesting samples and presentations. I recommend SRS, a freeware based on the new SAPI interface, as a clever replacement for External Writers.

    SHARE Proceedings on the Web are a unique source of information (many presentations). Click on "sessions" to access the all of them.

    Free monitors

    Not every site can afford Candle's or BMC's or Landmark's tools. Here are good quality free monitors.
  • Doug Nadel's ISPF tools : Tasid, a free MVS monitor ; QueryENQ, a REXX function to return ENQ status on a data set or any rname/qname ; and many more ! Doug is a well known ISPF expert. Doug's old page on IBM's site has disappeared.
  • MXI (MVS eXtended Information) from SEC in UK is an ISPF-based application that enables the MVS Systems Programmer to display important configuration information about the active MVS system. I find it gives in-depth information.

    IBM

    OK, IBM is a money-maker - however they offer some free stuff.
  • TRSMAIN is a free IBM compression utility that is available on the Tech Support IBM site.
  • The OpenEdition Setup Verification Program (SVP) from IBM: a very good sample of REXX building and using panels on the fly.
  • OS/390 UNIX System Services Tools and toys.

    Hercules

    Hercules is an open source software implementation of the mainframe System/370 and ESA/390 architectures. Hercules was also available here. And you may also build Hercules for Windows. There is also a discussion group for users of the Hercules ESA/390 mainframe emulator. You may run OS/360 under Hercules, read the Introduction to Generating and Running OS/360 on Hercules.

    Other (mainframe)

  • MVS documentation: interesting documents from Clemson University.
  • TCP/IP monitor: Dave Alcock's freeware for monitoring TCP/IP from ISPF.
  • LPALIST: interesting utility from Michael Cleary to analyze your LPA.
  • REXXFP: useful system-oriented subroutines for REXX from Gerard Nicol.
  • The REXX Macros Toolbox : David McRitchie's utilities. David is also a SPF/PC fan.
  • Leonard Woren has various MVS & TSO programs, including TSO QUEUE and TAPEMAP.
  • Jan Jaeger's S/390 System Utilities: Standalone utilities for MVS, including editor, VTOC list, device list, DASD ZAP etc. I have no time to review them, but ZZSA (stand-alone utility for DASD handling) seemed of interest.
  • Info-ZIP is an excellent compression product, that can run under MVS and is compatible with PKZip !
  • Shareware utilities from ColeSoftware.

    Other more or less mainframe related freeware products that I use every day

  • QWS3270: Jim Rymerson's very useful "Windows Sockets 3270 Telnet" - I use it to get connected to MVS systems across the Net.
  • WS_FTP : a popular FTP utility, available for download.
  • Whois-IP (freeware) does a lookup in the RIPE, APNIC and ARIN databases to find IP address info.
  • SnadBoy's Revelation, to recover saved passwords from those charming asterisks.
  • Speedtest to test the bandwidth delivered by your provider.
  • UltraEdit is the best NotePad replacement.
  • Aida32: a good PC system information tool.
  • Other products (do a Google seach !): Spybot - Search & Destroy can detect and remove spyware of different kinds from your computer ; ZoneAlarm provides Internet security for any individual computer by blocking unwanted Internet connections or malicious programs, like Spyware and Trojan horse ; HashCalc is an easy-to-use tool that allows to compute message digests and checksums for files.
