You can uninstall and unconfigure Agent Controllers to remove them from Oracle Enterprise Manager Ops Center. This also removes the assets managed by the Agent Controllers from Oracle Enterprise Manager Ops Center.
You can uninstall and unconfigure Agent Controllers from the user interface.
Follow this procedure to uninstall and unconfigure Agent Controllers from the user interface.
Note:
If you unconfigure and reconfigure an Agent Controller on an LDOM Control Domain, many LDOM management functions cease to function.

Follow this procedure to uninstall and unconfigure Agent Controllers from the command line.
Caution:
Do not uninstall co-located Agent Controllers from an Enterprise Controller or Proxy Controller system. Uninstalling a co-located Agent Controller can corrupt Enterprise Controller or Proxy Controller services.
Unconfiguring and uninstalling a Proxy Controller breaks its connection with the Enterprise Controller and removes the Proxy Controller software. All Assets discovered or managed by the Proxy Controller are also removed. The Agent Controllers installed on systems managed by the Proxy Controller are not removed.
Three methods are available for unconfiguring and uninstalling a Proxy Controller. The first two options are performed through the user interface.
Unconfigure and Uninstall the Proxy Controller from the user interface. This option connects to the Proxy Controller through SSH, then commands it to unconfigure and uninstall itself. You can only take this action if the Proxy Controller is reachable.
Remove the Proxy Controller from Oracle Enterprise Manager Ops Center. This option removes the Proxy Controller from the Oracle Enterprise Manager Ops Center infrastructure, but does not uninstall the Proxy Controller. You can remove a Proxy Controller even if it is unreachable. You can uninstall the Proxy Controller from the command line once it has been removed.
Unconfigure the Proxy Controller from the command line. The Proxy Controller software must then be uninstalled from the command line.
Note:
Do not remove themanagement/em-sysmgmt-p/cacao_pers_dirs
IPS package from the system even when the Oracle Enterprise Manager Ops Center is uninstalled. This IPS package contains a cacao directory which might be in use by the other applications on the system.The following topics are covered:

Unconfiguring a Proxy Controller breaks its connection with the Enterprise Controller.
Follow this procedure to unconfigure a Proxy Controller from the command line.
Uninstalling a Proxy Controller removes the Proxy Controller software and all Oracle Enterprise Manager Ops Center data. All Assets discovered or managed by the Proxy Controller are removed as well. The Agent Controllers installed on systems managed by the Proxy Controller are not removed.
You can uninstall a Proxy Controller from the command line. This may be necessary if the Proxy Controller is not responding to remote commands.
Note:
The co-located Proxy Controller that is installed with the Enterprise Controller cannot be uninstalled without uninstalling the Enterprise Controller.
Unconfiguring an Enterprise Controller removes user, authentication, and configuration data and unregisters the Enterprise Controller from Oracle. Data about Proxy Controllers and managed systems is retained. If you unconfigure your Enterprise Controller, you must reconfigure it before using Oracle Enterprise Manager Ops Center.
Uninstalling the Enterprise Controller removes the Enterprise Controller software and all Oracle Enterprise Manager Ops Center data.
Following topics are covered:
You can unconfigure an Enterprise Controller to reconfigure it or as a precursor to uninstalling.
