After a DB2 LUW Upgrade, Qlik Replicate tasks fail with:
"ReadNextBufferWait: Error reading buffer Error at 'Reading log records': Unexpected Error. Original SQLCODE -1263: ' message SQL1263N The archive log file "S0673464.LOG" is not a valid log file for database "REP" on database partition "0" and log stream "0".
Environment:
- Qlik Replicate
- DB2 LUW Endpoint
Resolution
Reload the task using the DB2 LUW Endpoint.
Cause
Qlik Replicate saves the last save stream position when a task is stopped.
Since the DB2 LUW environment was upgraded, the transaction log will be different and the task (tables) need to be reloaded.
An SQL Lite file called DB2LUW_TIMESTAMP_MAP is defined in the tasks directory, which stores the LSN/LRI position with the timestamp for the given task. This file includes the old DB2 LUW transaction log which is pointing to the old DB2 transaction log version.
