WebLogic Server Command Reference
If a server instance is in a deadlocked state, it can respond to
weblogic.Admin commands only if you have enabled the domain-wide administration port. (A deadlocked server is one in which all threads are struck trying to acquire locks held by other threads.) If you have not already enabled the domain-wide administration port, your only option is to shut down the server instance by killing the Java process that is running the server. You will lose all session data. For information on enabling the domain-wide administration port, refer to "Enabling the Domain-Wide Administration Port" in the Administration Console Online Help.
