Last updated on FEBRUARY 03, 2023

Applies to:

Oracle Database - Enterprise Edition - Version to [Release 10.1 to 10.2]
Oracle Database Cloud Schema Service - Version N/A and later
Gen 1 Exadata Cloud at Customer (Oracle Exadata Database Cloud Machine) - Version N/A and later
Oracle Database Exadata Express Cloud Service - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Information in this document applies to any platform.


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 primary node, and perform these actions on the primary 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.
