Applying service to CICS Transaction Server for z/OS

Service material for CICS® Transaction Server for z/OS® is distributed as APAR fixes and PTFs. 4Both types of change are called SYSMODs (SYStem MODifications).

Using SMP/E control statements, you can process SYSMODs in three stages:

  1. The RECEIVE control statement moves the SYSMOD into the PTF temporary store (PTS) data set. This operation is reversed by the REJECT control statement.
  2. The APPLY control statement moves the SYSMOD into the target libraries. This operation is reversed by the RESTORE control statement.
  3. At this point you can test the modified system.

  4. The ACCEPT control statement moves the SYSMOD into the distribution libraries. This operation is not easily reversed.

When you are dealing with APAR fixes, you should APPLY the SYSMOD, but not accept it. If you later obtain a PTF that solves the problem in a different way, you may be asked to RESTORE (that is, remove) the APAR fix and APPLY the PTF instead.

When you are dealing with PTFs, you should APPLY the SYSMOD, then test it. Afterwards you can ACCEPT it.

For background information about SMP/E operations, see the System Modification Program Extended: General Information manual. For more detailed information, see the System Modification Program Extended: Reference manual.


4.
An APAR (Authorized Program Analysis Report) is raised when you and your IBM® programming service representative agree that there is a CICS problem. You may then be given an APAR fix. When the problem has been analyzed, all users are sent a PTF (Program Temporary Fix) to correct the problem permanently on the current release. PTFs are incorporated into any future CICS release.
