Changing the logging mode of databases
About this task
You cannot turn on transaction logging for databases on
the primary database server while you are using HDR. You can turn
logging off for a database; however, subsequent changes to that database
are not duplicated on the secondary database server.
To turn
on database logging:
Procedure
- To turn HDR off, shut down the secondary database server.
- Turn on database logging.
After you turn
on logging for a database, if you start data replication without performing
the level-0 backup on the primary database server and restore on the
secondary database server, the database on the primary and secondary
database servers might have different data. This situation might cause
data-replication problems.
- Perform a level-0 backup on the primary database server
and restore on the secondary database server.
