ORA-00445 Error after installing Patchset 9.2.0.8 on 9.2.0.3 Database

fternoon folks,

I am currently running an Oracle 9.2.0.3 database on Windows Server 2003 with SP1. We are looking at upgrading our Database to 9.2.0.8 and I am getting the following error when trying to restart my instance after installing the 9.2.0.8 patchset.

"ORA-00445: background process "PMON" did not start after 120 seconds"

I get this error when I use the command "startup", "startup nomount pfile=ORACLE_HOME\database\init.ora", "startup migrate" and even "startup force" (I know I shouldn't use that but I figured might as well try it).

At first I thought I missed something and read the readme file again and followed every step and made sure I had all the system requirements met and ensured that I did all the pre-installation tasks that pertained to my environment. So then I rebuilt the database back to 9.2.3.0 and then tried patchset 9.2.0.7 hoping that it was the particular patchset and I just wasn't searching metalink correctly for any known issues. But again I get the same error.

I have checked for Trace files and found none, nothing in the even viewer, nor anything on the command line expect the above mentioned error.
Has anyone else experienced the same problem or am I just missing something obvious?

I have tried this now at least 5 times in about as many days, fresh rebuild every time to ensure that there is no conflict with any previous installation, settings or registry entries. I also confirmed the database was indeed running properly before running the patchset.

I have patched this database from 8.1.6 to 8.1.7 then migrated it to 9.2.0.1 then patched it again to 9.2.0.3 over the past 3 years with no apparent problems or snags.

Any input would be appreciated!

whts in the alert log?
