It depends on what libraries you want to save. You want to quiesce
the system to a point where there is no activity against the libraries you
want to save.
For example, on my system I need to quiesce to the point where all DDM,
ODBC, MQ Series, QBATCH and QINTER jobs are inactive because all of these
methods are used to access our production Customer Information System
libraries. This involves ending subsystems and certain TCP servers.
To identify what needs to be ended, check the locks on your application
libraries (WRKOBJLCK libname *LIB). All the jobs listed will need to be
ended for a few minutes while you obtain a checkpoint for the SWA.
In summary –
1. End all processes using the libraries you want to save.
2. Prevent any new access requests from starting until after a checkpoint
is reached.
3. Start your SWA save.
4. When the checkpoint is reached, restart the subsystems and servers you
ended in step 1. ==================================
