I got a question about Enterprise Controller high availability:
"If I have an Ops Center installation with a single Enterprise Controller, can I change my mind and turn it into a high availability setup?"
Yes. There are a few things you need to do to prepare, first:
- Back up your EC (it never hurts to do this before you make any big changes on the EC system).
- Install Oracle Clusterware in your environment.
- If you're using a local database, switch to a remote database.
Once you've taken those steps, you can set your current EC up as the primary node, and install and configure one or more standby nodes, using this procedure.
