Information in this document applies to any platform.
How can obsolete records in the MLOG$ tables be deleted to free up some storage usage?
Are these tables of any use for ROD ?
Why were they created in the OTM OLTP database and how should they be managed ?
These tables have even more records, than the parent tables.
The row count can be seen by running this query:
SQL> select table_name, num_rows from dba_tables where num_rows > 10000000 order by num_rows desc ;
The provided scripts to populate and maintain ROD using the materialized views does not have any effect on the MLOG$ tables,
even if the necessary jobs are present in the ROD database, and these jobs run successfully.
