Last updated on FEBRUARY 04, 2022

Applies to:

Oracle Database - Enterprise Edition - Version to [Release 9.2 to 11.2]
Information in this document applies to any platform.


NOTE: In the images and/or the document content below, the user information and environment data used represents fictitious data from the Oracle sample or bulit-in schema(s), Public Documentation delivered with an Oracle database product or other training material.  Any similarity to actual environments, actual persons, living or dead, is purely coincidental and not intended in any manner.

We see high archive log generation and most of the operations are internal. Using LogMiner, we get a similar output with the one below from v$logmnr_contents:

The internal operations are ten times up to hundred times higher than the normal DML.
Also, it can be observed that the internal operation is generated together with DML on a certain table, or
several specific tables.


No important changes made in the database. This problem can occur of the sudden.
