SYMPTOMS Creation of Standby Database from OEM 12.1.0.2 fails with the following error: The grid control database plug-in must be deployed on the agent monitoring the select host.   CAUSE Plugins directory at the agent side does not have the required plugin /U01/app/oracle/product/agent12c/plugins $ Ls-ltr Total 20 Drwxr-xr-x 7 oracle 4096 Nov 29 oracle. sysman. xa. discovery in_12.1.0.3.0 Drwxr-xr-x 7 oracle 4096 Nov 29 oracle. sysman. oh. discovery. plugin_12.1.0.2.0 Drwxr-xr-x 7 oracle 4096 Nov 29 oracle. sysman. db. discovery. plugin_12.1.0.2.0 Drwxr-xr-x 10 oracle 4096 Nov 29 oracle. sysman. oh. agent. plugin_12.1.0.2.0 Drwxr-xr-x 9 oracle 4096 Nov 29 oracle. sysman. emas. discovery in_12.1.0.3.0   Oracle. sysman. db. agent. pluginIs 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.

 

How does java + jade create a container and an agent on a remote host?

Grant select, update, insert, delete on *. * to root@192.168.0.200 identified by "password ";

That is to say, add the IP address of another person to the host.
