If you are migrating to 12.6.00 from a previous release of CA 1, consider the following:
The TMC file and the AUDIT file can be shared between 12.6.00 and any supported release of CA 1.
If you are running an unsupported release of CA 1, it is possible that the TMC and AUDIT files can be shared. For more information, contact CA 1 support. You can share both a standard TMC or a TMC created with the TMSXTEND utility in 12.6.00 and earlier releases of CA 1.
The VPD and RDS used with either r11.0 or r11.5 can be used with 12.6.00.
A published PTF (RO10161) added new options and deleted others. These changes were carried forward to 12.6.00. If you have not applied RO10161, review the changes documented in RI10751.
The CAIRIM Control Statement has changed for 12.6.00. The INIT program was renamed from L0C0INIT to L0C6INIT, and the VERSION changed from L0C0 to L0C6. Make these changes to the CAIRIM control statements.
New sample jobs are supplied in the CAI.CTAPJCL library. CA 1 includes two EARL libraries, one for the source and one for the Copybooks (record layouts). These changes have been made to the new supplied sample jobs. When running EARL jobs on a 12.6.00 system, use the 12.6.00 JCL. When running EARL jobs on a r11.5 or r12 system, use the existing JCL.
The names of all the optional user exists are user-specified. We recommend that you resource all user exists and reapply them as part of the 12.6.00 installation. Determine if the exits are needed. For example, in most sites TMSXITB (now called Exit-B) can be eliminated by including some ABEND= statements in the RDS. Exits TMSXITU (now called Exit-U) and TMSXITE (now called Exit-E ) can be eliminated when the TMC is extended using the TMSXTEND utility.
If you are running CA 1 11.5 SP4 or lower, an IPL is required to implement r12.6.
Note: If you have installed any of the CA 1 z/OS usermods from a previous release, they can continue to be used until the next scheduled IPL. With the IPL, we recommend that you put in the r12.6 usermods. The usermods include the failsafe usermod, CBRXUENT, CBRUXEJC, CBRUXVNL, and IGXMSGEX.
If you are currently running CA 1 11.5 sp5 (which includes RO02572) or higher, you can upgrade without an IPL. If you upgrade to 12.6 from r11.5 (sp5 or sp6) or from 12.0 without an IPL, you can go back to 11.5 (sp5 or sp6) or 12.0 and you do not have to perform an IPL.
IMPORTANT! To remove 12.6 dynamically, SECWTO=YES is required. For more information about the security setup of the BATCH, DEACT, REINIT resources for TMSINIT, see the Programming Guide.
If you perform an IPL and bring 12.6 active, an IPL is required to go back to 11.5 or 12.0. The CA 1 load library must be APF authorized and added to the system linklist.CA 1 initialization requires CAIRIM processing and TMSINIT processing. CAIRIM initialization processing for CA 1 must complete successfully before TMSINIT startup.
Initialize CA 1 using the TMSINIT PROC. The TMSINIT PROC executes TMSINIT to initialize CA 1 resident modules and tables, and to activate the message intercept. A report is produced showing the CA 1 system specifications and detailing any errors found. Before you execute production tape jobs, examine the output thoroughly.
