Oracle Database Discussions

Hi,
I had a database instance (say test_1) in my server and its home was /app01/app/oracle/product/10.2.0 ( This is 10.2.0.3 on RHEL 4). I did not created a sub directory for this instance like (/app01/app/oracle/product/10.2.0/*db_1*) B'cos I did not know that there are other instances are going to be in this same server. But now I want to install another instance say (test_2) and when I tried to have its home as /app01/app/oracle/product/10.2.0/db_2 it gave me an error saying that oracle-home already exists there in this location.

So I removed the oracle homes using oui. Now I want to install a fresh ORACLE_HOME in /app01/app/oracle/product/10.2.0/db_1 for my test_1 instance. (I have shut it down. I don't need this until I fix the Oracle_Home. Even If I have to create a new instance it is OK. So don't worry about the instance. ) and another home /app01/app/oracle/product/10.2.0/db_2 for my test_2 instance.


Now I tried to install freshly from /home/oracle/../database/ I tried to run the runInstaller, it is giving me this error.

OUI-10199: Unable to create home "OraDb10g_home1" at "/app01/app/oracle/product/10.2.0/db_1". There are existing homes with the same name and the same location.

But I have deleted those Oracle homes. How do I fix this mess? Am I overseeing anything?

Please help.
