Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHDB2035 INDOUBT RESOLUTION FOR UNIT * * OF WORK X'xxxxxxxxxxxxxxxx' IS * * INCOMPLETE FOR DB2 SUBSYSTEM XXXX * * after restart of DB2. * **************************************************************** * RECOMMENDATION: * **************************************************************** DB2 abended while processing a PREPARE from CICS. The transaction handling the prepare on the CICS side abends since DB2 has gone away. CICS erroneously turned off interest in syncpoint for this UOW for DB2 and by implication assumed DB2 would not be indoubt. DB2 was indeed indoubt and on on a subsequent Resync CICS was unable to inform DB2 of the outcome of the UOW and assumed DB2 was invalidly indoubt (DFHDB2035). Additional Keywords: MSGDFHDB2035 AD3Z ABENDAD3Z ASP7 ABENDASP7
Problem conclusion
DFHD2D2 has been altered to set the lot_current_request to lot_prepare_abended when a PREPARE has abended. DFHD2EX1 has been altered to not turn uefmsync off when lot_prepare_abended is on.
