AD2V

Explanation

The CICS-DB2 attachment facility issued a commit or abort request to DB2 but received a reason code 00F30805 indicating that connection to DB2 has been lost. This is due to DB2 terminating abnormally or being in the process of terminating abnormally. If the commit or abort request was preceded by a prepare request, DB2 may well still be indoubt. In this case, the CICS-DB2 attachment facility instructs CICS to remember the outcome of the UOW pending resynchronisation, which will happen when CICS and DB2 are reconnected. For an abort request not preceded by a prepare, i.e. a transaction abend or syncpoint rollback, DB2 will not be indoubt as the UOW was still inflight. DB2 will backout updates made by the UOW when restarted so there is no need for CICS to remember the outcome of the UOW.
