Sometimes it is necessary to rename targets in Enterprise Manager Cloud Control 12c. In my case I have listener targets discovered by EM12c with the hostname at the end of the target name: TESTDBA_LSN_dbserver1 As I work in a Veritas clustered environment, when the target switches to the other node (dbserver2) the listener target is relocated, but its name is always TESTDBA_LSN_dbserver1.

By selecting the Violation in the Configuration Best Practice for Oracle Database, we can display the message: By…
By Franck Pachot . A question that I had several times: in Enterprise Manager, in the screen about one SQL statement, the ‘statistics’ tab shows the number of executions, elapsed time, etc. Question is: which time window does it cover? There is a one hour chart above, and two timestamps displayed as ‘First Load Time’ and ‘Last load Time’, and we don’t know which one is related with the execution statistics numbers. I’ll explain it…
To remove an agent in the previous Oracle OEM Cloud Control 12c versions, you first had to delete its targets, stop the agent, and remove the host target. Only then were you able to remove the agent. In version 12.1.0.4, the decommission agent feature has been greatly improved. From the agent menu, you select the new feature Agent Decommission: The agent must be in stopped status to be decommissioned: It shows the targets which will…
