Step 3. Apply maintenance

To apply maintenance to the target libraries, use the Generated JCL data set member:

• $15MAPLY (may include multiple products)
  or
• @xxM2APL (individual product)

To bypass any HOLDDATA, remove the period (.) from the end of the APPLY command and add the following parameter to the APPLY command:

($14MAPLY only) Comment out the SMP/E APPLY steps for any other products that may be present in the JCL.

After you review and modify the JCL, submit the job to start the apply process.

1. Run the job in a job class suitable for long-running batch jobs.
2. You may be required to have SMP/E restore a USERMOD prior to applying a PTF to a module. SMP/E messages inform you when this action is necessary. After the PTF is applied, you must then reapply the USERMOD.
3. It is advisable to run an APPLY CHECK before applying any maintenance.

4. An APPLY may end with a non-zero return code, even though the APPLY CHECK ended with RC=0. This is because the APPLY may invoke external utilities, such as IEBCOPY or the linkage editor, while the APPLY CHECK only checks the SMP/E environment. A return code of 4 is expected from the linkage editor with messages similar to the following:

   IEW2609W 5104 SECTION xxxxxxxx USABILITY ATTRIBUTE OF NON-REUSABLE
   CONFLICTS WITH REQUESTED USABILITY OF REUSABLE.
   
   
   IEW2609W 5104 SECTION xxxxxxxx USABILITY ATTRIBUTE OF REENTRANT
   CONFLICTS WITH REQUESTED USABILITY OF REFRESHABLE.
   
   
   IEW2454W 9203 SYMBOL module-name UNRESOLVED.

   IEW2480W A711 EXTERNAL SYMBOL xxxxx OF TYPE LD WAS ALREADY DEFINED
   AS A SYMBOL OF TYPE LD IN SECTION yyyyyy.
   
   
   IEW2482W A712 THE ORIGINAL DEFINITION WAS IN A MODULE IDENTIFIED BY
   DDNAME SMPWRK3. THE DUPLICATE DEFINITION IS IN SECTION zzzzzz IN A
   MODULE IDENTIFIED BY DDNAME AXFAMOD.
