uninstalled old version, OUI question

running 9.2.0.5 on Unix AIX5L system. I'm following instructions from Oracle on how to removed old installations of oracle that the previous dba left on the server.
They start by having me rename the old directories first to make sure nothing breaks. That went fine. ex: /app/oracle/product/9.2 and ./8.1.6  and ./8.1.7 I would rename ./8.1.6 and ./8.1.7 to ./O8.1.6 and ./O8.1.7
Then the say to rename the old directory back to the name it was originally so OUI will recognize it and set your $ORACLE_HOME to the home directory of the install that you want to remove and then run the latest version of OUI that you have. So I mv ./O8.1.6 ./8.1.6 and ORACLE_HOME=/app/oracle/product/8.1.6
export ORACLE_HOME
then /app/oracle/product/92/oui/bin/runInstaller To my surprise when I get to the inventory screen of the OUI it displays all the old home directories. the 8.1.6 and the O8.1.7 after I uninstall the 8.1.6 and exit it has created a new directory name 8.1.7 with what looks like OUI file in it. Does anyone know why it does this? Received on Mon Jun 26 2006 - 15:25:25 CDT
