INITIMS Parameter

Determines whether CA OPS/MVS dynamically installs its own IMS AOI and CMD exits.

If you are a customer who has licensed the IOF but have z/OS images where IMS is never used, there is a performance advantage (CPU and storage) in setting the INITIMS parameter to NO on those systems.

When the INITIMS parameter is set to NO, the output of the OPSPARM SHOW(ALL) command processor does not include IMS parameters. The NO setting also inhibits the displays of IMSPARMS when you use OPSVIEW option 4.1.1. This characteristic reduces storage and improves performance. If you set the value of INITIMS to YES, all displays are available.

Default value

NO

Other possible values

YES

Note: Only those customers who have licensed the IOF component should set this parameter value to YES.
