Hi DBA's

We are setting up Oracle 8i Database and Oracle 9i Application Server on the same machine. Our machine is IBM RS6000 which is AIX 4.3.3 installed on it and have 512MB RAM.
But installation fails and it says that it can't findout the tnslistener, but on the other hand database is up running.
Can you kindly guide me to set ORACLE_HOME and other environment variables for this type of situation.
Thank in advance.
