This note should not be used with 11.2 and newer database installations.  For those releases, use "Safe repair/reinstall of the JVM Component in 11.2 and up (Doc ID 2314363.1)"

This Note shows how to remove and re-install the Core JVM objects in the database without affecting all the user owned Java objects. 

If the currently installed JVM in the database has a problem, a supported JVM re-installation would involve running rmjvm.sql and initjvm.sql but this would remove ALL Java objects in the database. 

The steps in this note will remove and re-install the CORE JVM while leaving all the user defined Java objects in the database untouched. 

The actions detailed here are highly destructive and so should not be attempted by novice users.  Additionally, the actions performed make direct changes to the underlying data dictionary tables, which should not be attempted without the guidance of Oracle Support Services. 

Oracle Real Application Cluster (RAC) customers should ensure that all nodes of the cluster are shutdown except the master node, and perform these actions on the master node only.

As with all destructive actions, Oracle Corporation strongly advises taking a FULL COLD BACKUP of the database before these actions are performed.
