How to Reload the JVM in 8.1.7.X (Doc ID 175472.1)

Last updated on JANUARY 30, 2022

Applies to:

Oracle Database - Enterprise Edition - Version to [Release 8.1.7]
Information in this document applies to any platform.


This article details how to completely de-install and then re-install the JVM in Oracle8i Release 3 (8.1.7.x) on Unix and Windows NT/2000/XP.  Customers on HP OpenVMS can use the script in this article to remove the JVM, but should see <Note:147350.1> also which details how to install the JVM on OpenVMS.


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 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 so that these can be reloaded once the JVM has been re-installed (see <Note:183825.1>).

Oracle Applications customers should contact Oracle Support and request <Note:191123.1> rather than attempt the actions in this article.

Oracle Parallel Server (OPS) 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 XML SQL Utility (XSU) into user schema's in 8.1.7, unless specifically required by your application as these products are included in the JVM in 8.1.7.
