You have the option
of using the administrative scheduler
to schedule tasks on query workloads, such as workload capture and
monitoring.
Without the administrative
scheduler, you can schedule tasks,
but you must keep the client application running on your workstation
and connected to the DB2® for z/OS® subsystem for the operations
to run when scheduled. If the connection to the subsystem is dropped
while scheduled tasks are running, those tasks cannot complete.
