The .war file can be found at C:\DLC\servers\pasoe\webapps\oemanager.war.

11) After all this is done the system name in the General Information and the servers view may differ from the system name in the Connection section, as follows:




Notice that the General Information section and the servers view show the system name as jzwwin764 (the old name) while the Connection section shows system name jzw1win764 (the new, correct name).

12) To correct the system name in all section, in the General Information section, using the cursor, change the system name in the Server Name entry of the General Information section. Then click File->save. This updates the system name in the General Information->Server name, the system name in the servers view and the system name at the top of the page, above the work Overview.
