Problem summary
**************************************************************** * USERS AFFECTED: * * All DB2 11 for z/OS and DB2 12 for z/OS * * users of REORG TABLESPACE SHRLEVEL CHANGE * * utility * **************************************************************** * PROBLEM DESCRIPTION: * * REORG TABLESPACE SHRLEVEL CHANGE * * failed with ABEND0C4 DSNUGLGR * * OFFSET04DE in LOG phase * * processing REDO only update log * * record * **************************************************************** * RECOMMENDATION: * * Apply corrective PTF when available * **************************************************************** User ran a REORG TABLESPACE SHRLEVEL CHANGE against a table space defined with 32K page size. During REORG execution, concurrent DML resulted in an update operation where it required DB2 to cut a separate UNDO and REDO log record to record the before and after record image. When REORG processed this REDO only log record in the LOG phase, it failed with ABENDS0C4 in DSNUGLGR + x'04DE'. The reported problem is caused by a small timing window where REORG starts the log apply point in between the generation of the split UNDO/REDO update log records. This resulted in REORG processing only the REDO update log record and failed with the subject error.
Problem conclusion
Code has been modified for REORG to correctly process the REDO only update log record without abending.
