Answer 1

First - you need to install java 1.6

If you want to change it for the whole OAS then alias java to your new java directory (1.6).
If you want to change it for a specific OC4J, then:

1. Open opmn/conf/opmn.xml
2. find the element which represend your OC4J
3. update the value in the element: process-type/module-data/category/data where id="java-bin", to your new java path
4. restart OAS
