DFHSPP executable module

Entry points

DFHSPPNA

Called by

DFHESP, DFHSP macro

Description

The syncpoint program is invoked during a user-specified syncpoint (by a DFHSP macro) or at task termination. For a rollback request only, DFHSPP calls DFHDBP to restore recoverable resources. It scans the DWE chain invoking the appropriate DWE processors, and performs the necessary syncpoint logging. It dequeues all resources enqueued by the transaction. DFHSPP processes any DWEs connected with the resource manager, and processes the RESYNC command.

The main subroutines of DFHSPP are:

SPP00005 - Write DWE log data
SPP02020 - Build a DWE chain that can be logged
SPP03000 - End.
