Undeploy the JD Edwards AppPack from Management Servers
Use this procedure to undeploy the JD Edwards AppPack from Management Servers.

In Oracle Enterprise Manager Cloud Control, navigate Setup > Extensibility > Plugins
With the undeployed plugin highlighted, right click and choose Undeploy From > Management Servers...
On Undeploy Plug-in from Server, General, enter the password for the SYS user of the EM repository.
Click the Continue button.
On Undeploy Plug-in from Server, Review, the panel warns that deployment of the plug-in on the Management Server will require downtime. All currently connected users will get disconnected from the Enterprise Manager. During the downtime period, users will not be able to connect to Enterprise Manager and Enterprise Manager will not monitor any targets.
Oracle recommends that you backup the repository or ensure appropriate recovery plans are in place prior to deploying the plug-in. Before you can proceed, you must click this checkbox:
Have you backed up the repository?
Click the Undeploy button.
On Undeploy Plug-in from Server, Confirmation, verify the undeployment is in progress and click the OK button.
On Plug-ins, the Recent Deployment Activities indicates that the undeployment of the Management Service has begun.
However, since OMS is shut down during the undeployment process, after a certain point in the deployment you cannot use the EM user interface to check the status and verify that it is complete and that OMS is backup.
To determine simple status and whether OMS is up or down, use this line command:
./emctl status oms
To view the deployment details, you can append the
-details
flag using this line command:./emctl status oms -details
Note: Any time you issue the check status command with the-details
flag you will be prompted to provide the SYS user password for the EM database as shown in the sample below.When the message appears indicating that OMS is being started it means that undeployment is complete and that the EM console should be available very soon, depending on how long the actual startup takes to complete.
