DBCA: Registering a database with OEM Cloud Control during creation

2019-04-19 Off By Markus Flechtner

When you create a database using Database Creation Assistant (DBCA), there is this screen “Specify Management Options”. For my test database on VMs I choose “Enterprise Database Express” as a simple standalone-management option most times. But there is this other option “register databases with cloud control” – I’ve never used this option before, I always used target discovery and promotion in OEM Cloud Control.

But when you want to use this option, there are these four data field which have to be entered:

  • EM Host
  • EM Port
  • EM Admin User
  • EM Admin Password

The first is obvious. The second is the upload port of your OEM Cloud Control (repository port). You can find this port when checking the status of the OEM agent on your database server (of course, a running OEM agent on your database server is a prerequisite for this procedure):

Agent is Running and Ready

So in my case, the port is 4903. For EM Admin user and password I choose SYSMAN:

And after DBCA has completed its work and the database is ready, you’ll find the database as a target in your OEM cloud control. No target discovery, no target promotion.

And – on the other hand – when you delete a database with DBCA, you can remove the OEM target, too:
