Correlation ID translation
The correlation ID is a DB2 field that identifies the task executed by DB2.
The correlation ID contains:
- For batch jobs
- Jobname
- For TSO applications
- Original authorization ID (the logon user ID)
- For applications using the DB2 call attachment facility
- Original authorization ID (the logon user ID)
- For CICS® transactions
- Connection type, thread type, thread number, and the transaction ID
- For IMS applications
- PST number and PSBNAME of the application
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).
