DFSFXC30
DFSFXC30 is the IMS Sync Point Manager. It coordinates all of the synchronization point processing in an IMS environment. A synchronization point might occur as the result of any one of the following:
· normal program termination
· abnormal program termination
· CHKP call
· SYNC call
· GU call to the I/O PCB
· ROLB call
· internal IMS ROLB call, for example if a deadlock is detected and a 'BC' or 'FD' status would be returned instead of a U777 abend
Hints
Most of the work for synchronization point processing is not done in module DFSFXC30. This module coordinates the function of the synchronization point processors.
