I've read it's possible to have Oracle 8 installed on the same machine as Oracle 9. Unfortunately I can't find any Oracle documentation on this. The installation guide for version 9 does not go into such scenarios.

The installation guide tells me that the oraInventory is a repository of all installed Oracle products. Does that mean that it should be updated with the details of the Oracle 9 installation I am about to do? Or will I end up with two oraInventory?

I have Oracle 8 installed in /u01. Under that I have a folder /u01/oraInventory and one named /u01/OraHome8. Should I set ORACLE_BASE to /u01 and ORACLE_HOME to OraHome9 before starting the installation. Or should I install version 9 in a completely seperate area?

I already have an 'oracle' user and an 'oinstall' [ORAINVENTORY] group for the Oracle 8 installation. I imagine that I can/should use these for the Oracle 9 installation?

Thanks in advance for any help.
