Updating an existing CFRM couple data set

To update an administrative policy that you have created (or add a new administrative policy) in the CFRM couple data set, you must run the administrative data utility (IXCMIAPU) against the CFRM couple data set that contains both the active policy and the set of administrative policies. The utility adds or changes policy data in the administrative policies only. The utility does not change any information in the system's copy of the active CFRM policy.

For example, if you want to update information in your active CFRM policy, you would run IXCMIAPU to change the administrative copy of that policy. (You omit the DSN and VOLSER keywords in the IXCMIAPU utility when updating administrative policies.) To switch to the updated policy, issue the SETXCF START,POLICY command. This command causes the system to copy your updated policy to the active policy. It is possible that not all changes that you specified in the updated policy will take effect immediately. See Transitioning to a new CFRM policy for a description of how CFRM updates an active policy.

Another way to update your active policy without losing the ability to return to it later is to make a copy of the policy, apply the necessary definition changes, and rename the policy. For example, if your active policy is POLICY1, define a new POLICY2 with identical definitions except for those that you want to change. If, after you activate the newly created policy, POLICY2, you decide to return to the original policy, POLICY1, you can issue the SETXCF START,POLICY specifying POLICY1.
