Notes:

  • IBM z/OS 2.4 has system changes that required updates to SMSDEBUG processing. For SMSDEBUG processing, upgrade to SL19287 or higher. Earlier versions of ACC will not provide correct results for SMSDEBUG processing.
  • IBM z/OS 2.3 has system changes that required updates to SRS ADDVOL processing for VSAM files. For VSAM ADDVOL recovery, upgrade to SL17353 or higher. Earlier versions of SRS will not get control to perform ADDVOL recovery.
  • IBM z/OS 2.2 has substantial changes to internal SMS control blocks that required source changes to ACC, SRS and SMSDEBUG. The updates affect all SMS controlled data sets – both VSAM and non-VSAM. Also, IBM made changes to internal EOV data structures that affected SRS. All previous releases of SRS will abend during ADDVOL recovery. Installations upgrading to z/OS 2.2 must install the latest release of SCC 6.1.
  • If APAR OA46827 (PTF UA76232 or UA76233) has been applied to z/OS 1.13 or 2.1, SCC must be upgraded to a minimum of SCC R6.1 SL15125. If your system(s) have either IBM PTF applied, SCC releases before SL15125 will not perform SRS ADDVOL processing on SMS files during space recovery attempts. For more information, examine the DTS61045 article in the support database.
  • IBM z/OS 2.1 has substantial changes to internal SMS control blocks that required source changes to ACC, SRS and SMSDEBUG. The updates affect all SMS controlled data sets – both VSAM and non-VSAM. If you are upgrading to z/OS 2.1, you must install the latest release of SCC 6.1.
  • IBM z/OS 1.13 has substantial changes to internal SMS control blocks that required source changes to ACC, SRS and SMSDEBUG. The updates affect all SMS controlled data sets – both VSAM and non-VSAM. Note: z/OS 1.13 installations must upgrade to at least SCC SL12051 to run DTS products..
  • IBM z/OS 1.12 no longer honors the unprotected page bit for nucleus storage backed by large pages (1 MB). The DIF memory update routine has been modified to use DAT OFF updates when necessary. Note: z/OS 1.12 installations must upgrade to at least SCC SL10320 to run DTS products.
  • Your current version information can be obtained with the following DIF console command: “F DIF,STATUS”
  • The Dynamic Install Facility (DIF) is not a licensed product, but is a required component under which all of the other DTS Software products run.
