The CTMWKLDT file in the IOA PARM library, which contains the Local Workload Policies, has a new format in version 9.0.20. Note the following effects of this change:
The new release supports the previous format of the file, so existing Workload Policies from releases earlier than 9.0.20 can be used in the new release. As soon as a Workload Policy from a previous release is updated, it is saved in the new format.
Workload Policy files from the new release are not supported in Control-M releases earlier than 9.0.20.
Sample Workload Policies provided in the new release do not work in Control-M releases earlier than 9.0.20. All provided samples are in INACTIVE status, to avoid impact on the Control-M monitor of any previous release. This is especially important when working in a Sysplex environment while upgrading to a new Control-M release, when some Control-M monitors may still be in an older release.
As soon as changes are made to Workload Policies, the CTMWKLDT member is no longer accessible through the on-line facility of a previous release. Therefore, it is recommended to save a backup of the Workload Policies local file CTMWKLDT in the IOA PARM before upgrading to the new release, in case you ever need to revert Control-M to a previous release.
If the Control-M monitor of a previous release is activated with a new version of the CTMWKLDT file in which one of the Workload Policies is activated, this may cause the Control-M monitor to fail.
