Install Sun Java JDK

Before you run the Oracle Business Intelligence installer, you should have completed the Java SDK 1.5.0 or later installations on the same machine on which you are installing Oracle Business Intelligence.

·         To discover the Java version that is installed, run the Java executable with the -version option:

$java –version

java version "1.5.0_16"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b02)

Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_16-b02, mixed mode)

·         To determine if JDK is already installed on the LINUX Environment Operating System and configured in the environment, use the following command:

$which java

/usr/java/jdk1_5.0_16/bin/java

·         Making the Java Platform Installation Writable

If you are installing using the Basic installation type, make the user or user group permissions writable for the user installing Oracle Business Intelligence, for all JDK 1.5.0 installation directories, subdirectories, and files.

To make the Java platform writable under LINUX, run the chmod command


Note:
You will get the following error message if java home doesn”t have writable permission

The Java Development Kit 1.5.0 or greater installation location is not writable, hence cannot install Oracle Business Intelligence.
The Java Development Kit 1.5.0 or greater installation location and all its files and subdirectories must have the writable user or user group permissions for the user installing Oracle Business Intelligence.

Have the system administrator give you user or user group writable permissions or try running the command "chmod -R a+rwx /usr/java".
