Known Causes

3 known causes
⚠️
Mismatched LOGGING Clauses

⚠️
Implicit LOGGING Defaults Differ
The table or tablespace default logging setting differs from the explicitly set logging setting of the index or overflow segment, causing an implicit mismatch.
⚠️
Altering Index Logging Inconsistently
An attempt to alter the logging attribute of either the index or overflow segment without altering the other, leading to a mismatch.
