Close down your production system
- From the Service Functions dialog on the production system on the controller, deactivate job submission.
- Unlink all fault-tolerant workstations in the network by using one of the available IBM Workload Scheduler interfaces.
- Before you proceed with the next steps, wait until all the events are processed
in the EQQTWSIN and EQQTWSOU data sets. To verify this, use the sample utility EQQCHKEV,
provided in the sample library.
The EQQCHKEV utility checks the data set structure of EQQTWSIN and EQQTWSOU which are the input and output end-to-end event data sets from the version you are migrating. The utility provides an informational message indicating the number of events still to be processed. When the data set contains zero unprocessed events you can proceed with the migration. The utility also checks the integrity of the data sets and issues an appropriate error message in case of corruption or inconsistency.
- From the Daily Plan dialog on the production system controller, create a replan or plan-extend batch job. Change the job card to contain TYPRUN=HOLD, and submit the job. Save the JCL in a data set in case you have to resubmit it to correct an error.
- If you specified CHECKSUBSYS(YES) in the BATCHOPT statement used by the batch job, change it to CHECKSUBSYS(NO). In the BATCHOPT statement used by the batch job, comment out the TPLGYPRM and JRUNHISTORY parameters, if they are used.
- Using the Query Current Plan dialog on the production system controller, check which JS file is currently in use on this system.
- Stop the controller and server, release the daily plan from hold, and make sure it runs successfully.
