Hi,
I am certificate (OCA and OCP) in the oracle database 10g and DB2 Database Administrator too.

Now I want to get the Oracle Application Server 10g and I would like to know if is that possible to install both on the same machine?
For example, how i set the environment variable because both use the same variable like ORACLE_HOME

Can someone help me to meet this.
If someone had a link to some web site
