Version 55 Availability

Concurrent with the General Availability (GA) release of z/VM 6.2, VSSI announces the immediate availability of Version 55 of our product suite (VPARS and VTAPE).

Summary of Changes for Version 55
  • Version 55 supports all z/VM releases from 5.4.0 thru 6.2.0.
  • This version implements a new software licensing scheme. Each registered user of VSSI products will need to download the following files from the VSSI FTP site:
    • The software package (via public userid.191 MDISK; e.g., ZVM620 VPVT5502)
    • The license file (via private userid.192 MDISK). (e.g., if your userid is VPnnnnyy, download and expand Pnnnn.VMARC; if your userid is VTnnnnyy, download Tnnnn.VMARC).
    • After download, the license file needs to be copied to the VSSI CP PARM disk as VSSI LICENSE. The product will not run without a valid VSSI license file. The software license code uses the customer license key to check the VSSI expiration date and/or running machine CPUID, as follows:
License TypeDurationCPUID_Checked
Trial60 daysNo
1-Machine1 yearYes
2-Machine1 yearYes
3-Machine1 yearYes
Site1 yearYes
  • The following actions are taken based on the number of days remaining until expiration:
Days RemainingAction
Greater than 30 daysNo action, no messages; processing continues
Between 30 and 15 daysWarning message written to OPERATOR console; processing continues
Between 14 and 0 daysCritical message written to user and OPERATOR consoles; processing continues
Between 0 and -30 daysCritical message written to user and OPERATOR consoles; processing continues
Greater than -30 daysCritical message written to user and OPERATOR consoles; soft ABEND issued.
  • This version is designed to support a CPXLOAD/CPXUNLOAD environment. The code will be automatically loaded during an IPL; additionally, VSSI modules can now be dynamically loaded and unloaded by the Systems Administrator after IPL via the VSCPX EXEC, by component, as follows:
ComponentLoad CommandUnload Command
VSSI CommonVSCPX ENAble VS CF1VSCPX DISAble VS CF1
VPARSVSCPX ENAble VP CF1VSCPX DISAble VP CF1
VTAPEVSCPX ENAble VT CF1VSCPX DISAble VT CF1
AllVSCPX ENAble ALL CF1VSCPX DISAble ALL CF1
  • The VSCPX EXEC is copied to the specified PARM disk; you can use it by accessing the PARM disk in read-only mode after IPL. For CF1 above, substitute your CP PARM disk virtual address. On z/VM 6.2, the primary PARM disk is typically PMAINT CF0, not MAINT CF1 as set in prior z/VM releases.
  • VSSI has moved the bulk of product code to a TXTLIB used by the CPXLOAD commands in VSSI PARM disk CONFIG files to load the system. Several critical stub files, however, remain in the CP Nucleus (NUC). Future maintenance of the stub file code will require a system reboot; all of the TXTLIB code (approximately 95% of the code base) will not require a z/VM IPL.
  • This approach is designed to reduce or eliminate the number of CP BLDNUC and subsequent re-IPL disruptions required by the application of VSSI fixes.
  • This version is designed to support a CPEXIT environment. All hooks to IBM HCP modules, as well as all cross-component VSSI module calls, have been converted to CPEXIT calls. This conversion makes it possible for the customer to disable/enable VSSI exits (via the VSCPX EXEC described above) while the system is still running.
  • All previous fixes applied to VSSI version 53xx have been applied to this release.
  • The VSSI build EXECs have been upgraded to support a CPXLOAD environment. For example, the VSCOPY EXEC now invokes a new EXEC, VSBLDCFG, to copy generated CONFIG files to the appropriate PARM disk. Additionally, many EXEC build messages have been improved for clarity.
  • This version does not yet support the SSI facility in z/VM releases 6.2 and above; SSI support is forthcoming shortly.
  • This version drops previous requirements for modification of the DIRECTXA module. Previous VSSI DIRECTXA modifications involved the support of SPECIAL statements for VTAPE devices (e.g., V3480) in the user directory, which is no longer necessary since IBM provided directory COMMAND support. All users are therefore requested to change any directory SPECIAL VTAPE directory statements (e.g., SPECIAL V3480) to CMD DEFINE type (e.g., CMD DEFINE V3480) statements.
