Hello,

I have an oracle database replicated on a DR site, using Data Guard, I want to perform a drill test by disconnecting the primary database and switch the secondary to active database. I should perform the following steps:

1- Stop the replication.

2- Shutdown and Backup Standby database at DR Site.

3-Open and Activate database at DR Site .

4-shutdown down and restart DR Site database nonarchivelog mode.

5- Perform some operations.

6-Rollback Procedure:

  • restore the old backup on the secondary database.
  • re-initiate the replication again.

Howdy, Stranger!
