Pipeline failure due to Redo Log expiry
Applies to Oracle Source (all variants) with Redo Log Pipeline mode.
Error Message Text(s) - The Redo Log has expired. Ensure a log retention period of at least 72 hours in your Oracle instance.

Potential Causes

Hevo is unable to read the Redo Log files as they have expired. This can happen if you have a sudden spike in Events which causes the Redo Log to expire sooner than expected and Hevo is unable to replicate it.
