AD2Z

Explanation

DB2 detected a deadlock and the CICS-DB2 attachment facility attempted a syncpoint rollback command for the transaction as DROLLBACK(YES) was specified for the DB2ENTRY or POOL. The syncpoint rollback command failed. Message DFHDB2070 is output to transient data detailing the transid involved and the EIBRESP2 from the failed syncpoint rollback command.

System action

The transaction is abnormally terminated with a transaction dump.

User response

Examine the eibresp2 value to determine why the syncpoint rollback request failed. One possible reason could be that the transaction running is a DPL server transaction which was DPLed to by a client transaction without specifying the SYNCONRETURN parameter. In this case syncpoints, or syncpoint rollbacks, cannot be taken by the server transaction, so DROLLBACK(YES) is invalid in this case.
