Correlation ID translation
The correlation ID is a Db2® field that identifies the task executed by Db2.
The correlation ID contains:
- Batch jobs
- Jobname
- TSO applications
- Original authorization ID (the logon user ID)
- Applications using the Db2 call attachment facility
- Original authorization ID (the logon user ID)
- CICS® transactions
- Connection type, thread type, thread number, and the transaction ID
- IMS applications
- PST number and PSBNAME of the application
- RRS applications
- The character string provided by the application during signon
Particularly for CICS and IMS it is useful to break the correlation ID into several parts, so that you can easily distinguish the transaction ID (for CICS threads) from the PSBNAME (for IMS threads).
