This post describes how to change the JDK for an Oracle Application Server 10.1.3.x installation. To check which JDK versions are supported with Application Server releases, check Metalink note 258833.1.

1. Stop all running Application Server processess.
2. Rename the current JDK directory:

1 2	cd $ORACLE_HOME mv jdk jdk.old

3. Install or copy the JDK version you need into $ORACLE_HOME/jdk
4. Start the Application Server processess.

You can check the JDK version:

1	$ /jdk/bin>./java -version

AIX 5L specials

If your systems are running AIX 5L there is some patching to be done. Assuming you’re using JDK 1.5 you have to apply patch 5261515.

After upgrading to a IBM JDK it is very well possible to run into the JAVAX.NET.SSL.SSLKEYEXCEPTION:RSA PREMASTER SECRET ERROR. In that case you have to modify the $ORACLE_HOM/jdk/jre/lib/security/java.security to

1 2 3 4 5

security.provider.1=com.ibm.jsse2.IBMJSSEProvider2 security.provider.2=com.ibm.crypto.provider.IBMJCE security.provider.3=com.ibm.security.jgss.IBMJGSSProvider security.provider.4=com.ibm.security.cert.IBMCertPath security.provider.5=com.ibm.security.sasl.IBMSASL

and create a symbolic link (or copy the jar) from the directory $ORACLE_HOME/jre/lib/ext/ibmjsseprovider2.jar to $ORACLE_HOME/jdk/jre/lib/ibmjsseprovider2.jar as described in Metalink note 746423.1.
