Absolutely. Totally supported. No hacks. IIRC, this has been true since at least the late 80's and Oracle version 6.

The trick is to install each in it's own ORACLE HOME, setting the appropriate environment variables (ORACLE_HOME, ORACLE_SID, PATH) to separate between versions - consider SID as the separation between 'databases' of the same version.

The separation does not require separate userid, although some of us (self included) occasionally use separate userids for management, not tech, reasons.

I personally have had multiple instances concurrently running on each of Windows 2000, Linux (SuSE SLES8) and Solaris: in Linux it's been Oracle9i R1, 2x Oracle9i R2, one Oracle10g; on my W2K-Pro laptop it's been 8iR3, 9iR1, 2x9iR2.

This is an example of "Yet another wonderfully documented thing" (YAWDT [tm]).
