DFHSPP
DFHSPP is the CICS syncpoint program. It can be invoked when an application program requests services such as a SYNCPOINT, SYNCPOINT ROLLBACK, ISSUE PREPARE, or the EXEC CICS RESYNC command.
DFHSPP is also called at task termination, a DLI TERM request, or during transaction restart.
Hints
If high activity occurs in this module, examine the syncpoint requests made by the CICS application programs.
