Also if you install the 10g "Companion CD", or as I like to call it "Disk 2" (contains; java, apache, HTML DB, etc.), it must go under its own Oracle home. Seems 10g "Companion CD" contains 9i versions of some software.

I have actually adopted this nomenclature for new Oracle 9i servers I am setting up and install 9i into two homes ...product/9.2.0/db1 and db2. I can then upgrade each home separately and migrate databases to the=20 upgrade one by one. I just need to make sure I migrate all to the=20 "higher" home before I need to install a new patchset (or else add a 3rd home).
