If you don't like the "1" you may as well get rid of the entire db_1 suffix. 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 upgrade one by one. I just need to make sure I migrate all to the "higher" home before I need to install a new patchset (or else add a 3rd home).
