ASP3 An application has requested syncpoint, either via EXEC
CICS SYNCPOINT or implicitly via EXEC CICS RETURN. The coordinator of the syncpoint is not this CICS system but is remote. During the
syncpoint protocol the remote coordinator has decided that the unit of
work cannot be committed and must be backed out.
This error can occur with external resource managers connected to CICS via the resource manager interface (RMI) as well as CICS systems connected via LU 6.2, and MRO. If an external resource manager such as DB2 is the only recoverable resource updated in the transaction, the recovery manager (RM) domain can optimize the syncpoint protocol. In
this instance, the external resource manager becomes the syncpoint
coordinator. In this instance if the external resource manager returns
with a backed out response, an ASP3 abend results.
System Action: The transaction is abnormally terminated and recoverable resources updated by the unit of work are backed out. The EXEC CICS HANDLE ABEND command cannot handle this abend.
User Response: Refer to the remote coordinator system to determine why the unit of work was backed out.
