When we want to stop all the loading schedule jobs for system refresh, system upgrade, system migration in production. It is better to stop all the jobs before lock users and down the system to avoid the jobs fail or there is pending loading and loading table is not update correctly.
There are the standard program to do it.
1. Before run the program, there will be the Release jobs and active jobs
2. Run program BTCTRNS1, there is no input parameter, after execute all the release jobs will be suspended but the active jobs will be continue until it completed
However, for the PC loading, after the active loading is completed, the next loading will be suspended as well
The process will not error but if we see the status it will display there is no job. The process will not continue
We should remark on the ST13 what PC is not yet complete in order to double check when system is up again
3. After system is up and test complete, we can run program BTCTRNS2 to resume the jobs. There is also no input parameter
All the jobs will continue and provide the detail of delay in second
PC will be continue
After run the program to suspend, we still can run the schedule job manually, it is no blocking. The program will suspend only the current release job when program is executed.
