Cause
This error occurs when the jdbupgrade ReplayJournals command encounters an incomplete journal. A journal is considered incomplete in the following scenarios.
It was not properly closed, which normally means the database that created the journal was not closed and requires recovery.
The journal is truncated; that is, the logical end-of-file stored in the journal header is greater than the physical file size.
The last record in the journal is not a database close or audit switch.
Action
Ensure that all journals used for upgrade replay are complete and the database was closed before the final journal set was captured. The jdbutil verify journals operation can be used to check journal integrity.
