If your CICS application needs to use more than one PSB, you must use the method terminatePsb in class IMSServiceRequester to release the first PSB used, then use schedulePsb: to schedule the second PSB. The method terminatePsb is analogous to a TERM call and commits database changes.
"Issue a TERM call to end the PSB" serviceRequester terminatePsb.
When your program ends the PSB, CICS causes a CICS syncpoint, commits changes, and frees resources for other tasks.
