Hi, ASG recently provided fixes to eliminate use of user key common storage by TMONCICS. Past due but well done this provided not only a storage key change but leveraged MVS/ESA technology to eliminate some common storage use. Kudos to the TMONCICS development team for doing a complete job while they had the code open!
PTF TH02641 Resolution: The PTF reworks the use of the secondary addressing mode cross memory technique replacing it with access register mode usage in the Cross System Monitor. This change removes much the need for CSA storage and CSA resident programs. Remaining required CSA areas are allocated and updated using storage protect key 0. SRB related CSA storage is allocated for the life of the SRB only. No CSA workarea is required for tce session or system tasks. With the related updates to the LTSS200 via PTF level TQ01787 and the associated TH02650 and TH02651 PTFs, the TMON for CICS/TS system no longer uses CSA storage in any user storage protection key, and now has a minimal CSA/ECSA storage requirement. DEPENDENCY: The Specific PTFs required for the LTSS200 FMID are: TQ01784 TQ01787 Be sure the LMKLOAD dataset used for your ASG-TMON for CICS/TS product has this minimum service level installed. DOCUMENTATION: This is one of a set of three PTFs that remove the use of user key CSA storage by the TMON for CICS TS product. The three PTF's are: TH02641 - Updates to CSM region Modules (this PTF) TH02651 - Updates to CICS resident DCS Modules TH02650 - Updates to LFS Modules Messages and codes: ----------------------------------------------------------- TMONI0001W - Z/OS 1.8 COMPATIBLE OPERATION REQUIRES TSS PTF TQ01787 Reason: The support for removing use of user key CSA is applied to the Cross System Monitor, however, the corresponding support PTF TQ01787 (or later) has not been detected. The CSM will still operate normally if user key CSA allocation is allowed, however, some user key CSA allocated on behalf of the TCE product by The LTSS200 function will still exist. If the z/OS 1.8 option to prevent allocation of user key CSA is in place the CSM will fail when the user key CSA allocation attempt is made. User Action: Apply the required Strategic Services PTF level and restart the Cross System Monitor. ----------------------------------------------------------- Best Regards, Sam Knutson, GEICO Performance and Availability Management mailto:[EMAIL PROTECTED] (office) 301.986.3574 ManagementSpeak: This is a "best practice."
