CA MIM 12.0 is only compatible with external systems that are running with COMPATLEVEL=11.81, 11.9, or 12.0. Bringing the compatibility maintenance to the current CA MIM release can be required, before installing CA MIM 12.0.
The following CA MIM PTFs provide support for COMPATLEVEL=11.81:
To determine the current COMPATLEVEL value of your active CA MIM tasks, use the F MIM,DISPLAY MIM INIT command.
The simplest method of upgrading to 12.0 is by changing COMPATLEVEL=12.0 in the INIT member. Then start CA MIM 12.0 on all systems with a control file and checkpoint file format. However, this change requires a global CA MIM outage. The following examples show alternate upgrade methods that avoid the global outage.
Example for upgrading from CA MIM 11.9 to CA MIM Release 12.0:
No special CA MIM 11.9 PTFs are required for CA MIM 11.9 before upgrading to 12.0. Follow the standard COMPATELVEL upgrade process. For more information, see the CA MIM Statement and Command Reference Guide and the CA MIM Programming Guide.
Example: Upgrading to CA MIM for z/OS Release 12.0 with VM systems in the MIMplex requires the following steps:
Note: CA MIM VM does not support COMPATLEVEL=11.9 or 12.0.
Note: For more information about the CA MIM ACTIVATE COMPATLEVEL process, see the CA MIM Programming Guide and the CA MIM Statement and Command Reference.
Example for upgrading from CA MIM 11.8 to CA MIM 12.0:
