Our $ORACLE_HOME/jdk/bin/java is version 1.5.0
we need to upgrade to 1.6.24 ..... where is documentation for this upgrade
or, what are these upgrade steps:
The JVM is an integral part of Oracle and without the proper, certified version of the JVM the database will not run properly. In fact if you use Oracle installer and elect to remove the JVM the database itself will be removed also.
Oracle 11g installs with JDK 1.5 and that is the ONLY version that is certified to work properly with 11g. If you attempt to use anyother version you are violating your support contract and will likely have errors.
The installed version of the JDK is the version that Oracle itself uses and is the version that will be used for any Java classes that you load into the database and run from within Oracle.
You are free to use any version of the JDK you want for external Java applications.
