Obtaining and applying the fix
When the problem is solved, a code is entered in RETAIN to close the APAR, and you might be provided with an APAR fix.
You can ask your Support Center about the progress of your APAR at any time, particularly if it is a high-severity problem. When the change team resolves your problem, the team might want you to test the fix. If you are asked to test the fix, provide feedback. When the change team is confident that the fix is satisfactory, you are notified, and the APAR is closed.
If the solution involves a change to a CICS® VR module, and no APAR is yet raised, you might be supplied with a ZAP or a USERMOD.
The change is distributed later as a PTF. If you want a PTF to resolve a specific problem, you can order it explicitly by its PTF number from the Support Center. Otherwise, you can wait for the PTF to be sent on the PUT.
