This article details how to completely de-install and then re-install the JVM in Oracle10g Release 1 (10.1) and Release 2 (10.2).
The actions detailed in this article are highly destructive and so should not be attempted by novice users. Additionally, the actions performed in this article make direct changes to the underlying data dictionary tables which should not be attempted unless under the guidance of Oracle Support Services.
As with all destructive actions, Oracle Corporation strongly advises taking a FULL COLD BACKUP of the database before these actions are performed. In addition, as removing the JVM removes ALL user owned JAVA objects also, such as APPS schema objects, an export dump of all user schema's containing JAVA objects should be taken if required, so that these objects can be reloaded once the JVM has been re-installed (see <Document 183825.1>).
Oracle Applications customers should contact Oracle Support rather than attempt the actions in this article, see <Note:191123.1> for the procedure to follow here.
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.
It is not necessary to install the XML Developers Kit (XDK) or the XML SQL Utility (XSU) into user schema's in 10.1.0.x, unless specifically required by your application, as these products are included in the JVM in 10.1.0.x.
