Shutdown Oracle Processes

I need to shutdown all of the Oracle processes before upgrading from oracle to I stopped the listener and shutdown the database. I typed ps -ef | grep ora to see what processes were running. But I don't know how to stop them before starting the upgrade. Could someone provide instructions? Thanks!

depends on the process.  
the full list of oracle processes would be
ps -fu oracle
Assuming you are logged in as oracle, you will have at least one shell process (sh, ksh, csh etc) and you may see the grep process.
If you can print the list here, we may be able to help you decide which processes need stopping, however, stopping the listener and database should be enough.

in Solaris 8 / 9 you can use
pkill -U oracle
to kill all of oracle's processes, but this may not be necessary

I didn't realize that the other processes that I saw was due to there being 2 databases. When I shut down the second database I only saw the two processes that you mentioned:

 oracle  1200  1189  0 12:25:48 pts/6    0:00 ps -ef
  oracle  1189  1186  0 12:21:14 pts/6    0:00 -ksh

I thought everything was fine but when I run the Universal installer to upgrade Oracle I get an error:

The following processes needs to be shutdown before continuing:


How do I shutdown this process?

I issued the command pkill -U oracle
However, it did not kill the above mentioned process.
