Repeating agent 0C4 ABEND in RTGAR in Agent. 2. Incorrect conversion routine date and time fields in Enhanced 3270 Thread History longest Waiter screen KDPHLWAT. 3. ISPF online monitor "DB2" and "LOOK" commands receive error message FPEM550 for Db2 13 subsystems. 4. S0C4 ABEND LMOD=KO2PCTOF OFFSET=004CE2 Classic NTH or Enhanced 3270 UI Thread History is enabled. 5. S0C1 ABEND in recovery routine after timeout occurs. 6. Incorrect handling of records if IFI buffer size is bigger then 16MB for Thread History processing. 7. Incorrect handling of new version VSAM datasets for Classic NTH and Enhanced 3270 Thread History during migration from 550 to 610. 8. KO20135W ABEND follow with S0C4 if filter options like PLAN() CONN() CORR() are used in RKD2PAR(COPT<ssid>) member. 9. The logic for displaying the partition number was missing in the RECTRACE report when the lock resource type is an index manager tree (P-lock). 10. The logic for displaying the partition number was missing in the LOCKING report when the lock type is PART SPL. 11. In certain cases, generating a RECTRACE report for IFCIDs 411 and 412 may result in an ABEND S0C4. 12. TKO2SAMP members with Performance Database Descriptions are missing line numbers. 13. When the Accounting Reduce process runs with other significant below the bar memory residents present and an exceptionally large input file is processed, the regions storage can become fully exhausted, resulting in job failures. 14. Java Client does not show data for switched Data Sharing Group member. 15. When OMEGAMON collector started on z/OS 2.5 with VSAM or THVSAM options it will ABEND during VSAM switch. 16. If Db2 data section is not present, we skip end user ID processing leading to message KO2D0001E. 17. While collecting data in Snapshot History (For Java Client interface) from Db2 data sharing group sporadic memory overlays happen for unknown reasons. 18. Old product name is still displayed in PDS history summary workspace. 19. Old DPSYEXC table should not be used to display DSG summary data. 20. Incorrect data in DSC_SIZE field.
Problem conclusion
1. Suppress repeating RTGAR 0C4 ABEND messages. 2. Corrected conversion for date and time fields in KDPHLWAT. 3. Corrected Db2 13 support for "DB2" and "LOOK" commands in ISPF interface. 4. Historical record processing was updated to resolve S0C4 abends. 5. Recovery routine has been updated to avoid S0C1 abend. 6. Corrected handling of IFI buffer lager then 16MB. 7. Processing of previous version history VSAM datasets was fixed to avoid KO20136E errors. 8. Filter handling was corrected to eliminate ABEND. 9. Logic for displaying the partition number in the RECTRACE report when the lock resource type is an index manager tree (P-lock) has been added. 10. Logic for displaying the partition number in LOCKING report when the lock type is PART SPL has been added. 11. Processing of IFCIDs 411 and 412 in the RECTRACE report has been updated to resolve the S0C4 abend. 12. Missing line numbers for members with Performance Database Descriptions have now been added. 13. The region utilization driven externalization logic for Accounting Reduce process was redesigned to address job failures when large input data sets are used. 14. Fixed issue in Data Server when switching to selected Data Sharing Group member in Java Client. 15. Fixed how EXECUTABLE=NO is handled for z/OS 2.5 version to avoid S0C4 ABEND during VSAM switch 16. Leave end user ID empty if it's not present. 17. Additional checks of data integrity added to avoid memory overlay. 18. Correct product name. 19. Use new KPISTAT table to display DSG summary data. 20. Fix DSC_SIZE field display.
