Upgrading JAVA Version

First check whether the instance is UP or DOWN (The Target instance where you are going to upgrade the java version)

It is mandatory that the target instance should be in UP state when you are going to upgrade the JAVA Version.

[root@server2 ~]# cd /usr/java/

[root@server2 java]# ls

You will find the rpm package as follows

jdk-1.6.0_26-fcs.i586.rpm

jdk-1_5_0_08-linux-i586.rpm

Install the rpm package using the following command

[root@server2 java]# rpm –ivh <rpm file name>

After the installation has finished

Connect to winscp as the target’s application user and navigate to the following path to find the CONTEXT_FILE

For 11i: $APPL_TOP/admin and find the .xml file

For R12: $APPL_TOPl/admin/ and find the .xml file

Now open the ndev_oraapps.xml file and replace all the occurrence of the old version with new one as follows

Find: /usr/java/jdk1.5.0_08

Replace: /usr/java/jdk1.6.0_26

Now save the file and exit the winscp

Now run the autoconfig file.
