Setting up IMS notification exits

InfoSphere® Classic CDC for z/OS® uses its own versions of two IMS notification exits (DFSPPUE0 and DFSFLGX0) to inform the IMS log reader service about the start of IMS subsystems and the start and stop of DL/I batch jobs.

About this task

You must perform some tasks to set up these Classic versions of the IMS exits:

The partner program exit (DFSPPUE0): Informs the IMS log reader service about the start of IMS subsystems, enabling change data capture to include participating subsystems when they start during replication.
The logger exit routine (DFSFLGX0): Informs the IMS log reader service about the start and stop of DL/I batch jobs, enabling change data capture to suspend ordering operations for participating subsystems for the duration of each job step that issues DL/I calls and has the Classic logger exit installed.
