Error description
ABENDS0C4-4 S0C4-11 in KO2CDSY+D46 at PM42983 level The same segment of the memory object is being used by two different control structures: ALLTHOUT and NC#CCPUS. One program freed the segment but continued using, and another program obtained the same segment. This is the result of the overlay. Storage is being freed when switching DB2s, but pointers are not cleared. Dump Title: OMEGAMON II FOR DB2: COMPID=5655OPE00, JOB=OMXD2DY , LMOD=KO2CDB2A#L, CSECT=#UNKNOWN, OFFSET=00C8CA 00 0159 00798938 PGM 011 077D1001 BCCAAD4E 00040011 00000048 00 0159 00798938 CLKC 077D1001 BCCAAD4E 00001004 00FDAC50 00 0159 00798938 DSP 077D1001 BCCAAD4E 00000000 40C76C90 00 0159 00798938 PGM 011 077D1001 BCCAAD4E 00040011 00000048 00 0159 00798938 PGM 004 077D1001 BCCAAD52 00040004 00000000 00 0159 00798938 *RCVY PROG

Pointers were not cleared, and the areas were re-used. Also, some storage areas were not freed but re-allocated for the new DB2. PROBLEM CONCLUSION: Clear pointers to freed areas. Ensure all storage is freed or re-used appropriately.
Problem conclusion
Clear pointers to freed areas. Ensure all storage is freed or re-used appropriately. KEYWORDS : ABEND0C4 KO2CDSY +D46 CPU STATISTIC DB2 SUBSYSTEM
