oracle.sysman.db.agent.plugin is missing which is required for monitoring.
 

SOLUTION

to create standby database on a new server, we still need a plugin to be deployed on the agent.

Please do the following steps:

1. Login to 12C Cloud Control
2. Navigate to Setup --> Extensibility
3. Select the option Plugins
4. Expand the option "Databases"
5. Select "Oracle Database"
6. Expand the option "Deploy On" and Choose "Management Agent"
7. In the page displayed, Click on "Add" to add the Agent on which plugin needs to be deployed (On the server where standby is created).
8. After adding the agent name, it will run the prerequisite check, after successful completion of prerequisite check, click on Next.
9. A Confirmation message about deployment of database plugin on Management Agent will be displayed.
 
This will complete the deployment of database plugin to management agent.

Once this is done, create standby database.
