Register product using IFAEDREG service. 2. ISPF online monitor "DB2" and "LOOK" commands receive error message FPEM550 for Db2 13 subsystems. 3. Incorrect conversion routine date and time fields in Enhanced 3270 Thread History longest Waiter screen KDPHLWAT. 4. If Db2 data section is not present, we skip end user ID processing leading to message KO2D0001E. 5. While collecting data in Snapshot History (For PE Client interface) from Db2 data sharing group sporadic memory overlays happens for unknown reasons. 6. 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). 7. The logic for displaying the partition number was missing in the LOCKING report when the lock type is PART SPL. 8. In certain cases, generating a RECTRACE report for IFCIDs 411 and 412 may result in an ABEND S0C4.
Problem conclusion
1. OMEGAMON Db2 will now register the product at initialization using the register service IFAEDREG. 2. Corrected Db2 13 support for "DB2" and "LOOK" commands in ISPF interface. 3. Corrected conversion for date and time fields in KDPHLWAT. 4. Leave end user ID empty if it's not present. 5. Additional checks of data integrity added to avoid memory overlay. 6. 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. 7. Logic for displaying the partition number in LOCKING report when the lock type is PART SPL has been added. 8. Processing of IFCIDs 411 and 412 in the RECTRACE report has been updated to resolve the S0C4 abend.
