In Oracle CDC Streaming, data is collected normally for some time, then new events stop arriving with the following error:
Redo Thread 1 is inconsistent;
failed to find log with sequence 927401
On the Oracle side, Thread 1 / Sequence 927401 does exist and is currently available:
ARCHIVED=YES
DELETED=NO
STATUS=A
DEST_ID=1
LOG_ARCHIVE_DEST_1 is also VALID / LOCAL.
This looks similar to Debezium issue DBZ-1801 related to archive log deduplication in Oracle RAC.
Could you please confirm:
- Which Debezium Oracle Connector version Foundry is using
- Whether the
DBZ-1801fix is included or backported - Whether this behavior could be related to the same RAC archive-log/thread handling issue
For the same SEQUENCE#, records also exist for other redo threads, and some of them are DELETED=YES / STATUS=D.
