OCI-55506

Transaction performed unsupported change

Cause

A transaction in the dependency DAG performed some action that cannot be backed out. You can back out a transaction, only if undo has been logged for all of its operations. Note some operations do not log undo, such as Insert Direct Load and LOB changes. If you encounter a transaction that has performed any of these operations, you cannot back it out.


Action

The specified transaction cannot be backed out.
