How to make sure that events are not lost

About this task

Use one of these methods to ensure that events are not missed between the time IBM® Z Workload Scheduler is taken down and JES (JES2 commands are given in the example) is taken down:
Method 1
  1. Remove the system being stopped from the JES2 MAS by placing it into independent mode (issue $T MEMB(n),IND=Y, where n is the member number of the LPAR obtained from the $DMEMBER command output).
  2. Allow the jobs currently running on this system to complete.
  3. Stop the tracker (P OPCx).
  4. Stop JES.
  5. Re-IPL.
  6. Restart JES.
  7. Restart the tracker.
  8. Resume normal work by issuing $T MEMB(n),IND=N, where n is the member number of the LPAR obtained from the $DMEMBER command output.
Method 2
  1. Abend JES2 ($PJES2,ABEND).
  2. Stop the tracker (P OPCx).
  3. Re-IPL.
  4. Restart JES. This will be a hot start.
  5. Restart the tracker.
Method 3
  1. Take the tracker down (P OPCx).
  2. Bring it up again under the master scheduler (S OPCx,SUB=MSTR). Remember that a tracker cannot use JES services (SYSOUT data sets, JCC) if it runs under the master scheduler.
  3. Bring down JES.
  4. Take the tracker down (P OPCx).
