This page won't explain how to set up a complete dataguard configuration, but only tells you how to activate it, when you database was offline. So, I suppose here that you have set up succesfully your dataguard.
There isn't a lot of things to tell here, but it's always easier to have a page to remember these things that we are aren't used to do all the days.
- Enable the listener on all database.
- Open the primary database
- Mount the standby database
- Enable the standby database to do automatic recovery
So, to enable the listener, you only have to do :
# lsnrctl start
on all the host of you dataguard configuration.
Then, open your primary database by doing this :
Then, mount your standby database :
SQL> startup mount
And finally, do the automatic recovery on your standby standby database, so do this :
SQL> alter database recover managed standby database disconnect from session;
