COMPATLEVEL Considerations

If you want to run CA MIM in mixed-level mode, we recommend that you run your current CA MIM r11.7 MIMplex at COMPATLEVEL=11.7 before starting CA MIM r11.8 on any system in your MIMplex. This prepares your current MIMplex for an eventual migration to COMPATLEVEL=11.8.

The code associated with certain new release features is disabled if the new feature is incompatible with a lower level release of CA MIM running in the MIMplex. After the newer release of CA MIM has been installed on all systems in the MIMplex, issue the following command to activate certain new CA MIM features:

ACTIVATE COMPATLEVEL=xx.x

This capability lets you run newer and older releases of CA MIM in the same MIMplex without compromising data integrity and lets you control when certain new feature code is activated.

You can use the F MIM,DISPLAY MIM INIT command to determine the current COMPATLEVEL value of your active CA MIM tasks.

If you are running COMPATLEVEL=11.7 and you want to reach COMPATLEVEL=11.8, issue the following command. (This assumes that you are running CA MIM r11.8 on all systems in the MIMplex.)

F MIM, ACTIVATE COMPATLEVEL=11.8

Note: For more information about the CA MIM ACTIVATE COMPATLEVEL process, see the CA MIM Programming Guide.
