I am rusty at this. Its been a while since I have done an upgrade in Unix.I am testing mock upgrades from 81741 to 9.2 on an HPUX environment. We have 2 databases on this unix box. DB1 an DB2. DB1 was already upgraded from 81741 to 9204. Now that I have to upgrade DB2 do i just source the .profile to the new oracle home and perform the upgrade? the Oracle home has already been patched.
