The admin server console shows all deployments in INSTALLED state when they should be showing as ACTIVE but the applications are behaving normally.
There is no valid deployment state as “Installed.” The deployment state is stored in “weblogic.management.runtime.AppRuntimeStateRuntimeMBean.”
“Installed” is a console text string that indicates the LibraryMBean is present in the configuration. Although the libraries stay in “Installed” state, they will be available to the applications referencing it without any problems.
The “Installed” state can be changed to “Active” by rebooting the domain (admin servers as well as managed servers). Rebooting the domain will change the state from “Installed” to “Active.”
The Mbean details can be checked at http://docs.oracle.com/cd/E12839_01/apirefs.1111/e13945/weblogic/management/runtime/AppRuntimeStateRuntimeMBean.html
