While upgrading 10.2.0.5 database to 11.2.0.3 + Patch 8 on Windows 2008 R2 I got an error message
ORA-00942: table or view does not exist while DBUA was executing “Upgrading Oracle Server” step.
I ignored the error and proceed with an upgrade. A quick grep of the log revealed this:

Rem for non-consolidated replays. Since this is an upgrade, this rule holds.

It’s a known bug according to MOS Note 1465852.1 “ORA-00942 reports during upgrade to 11.2.0.3 using manual or DBUA”. This bug affects only Oracle 11.2.0.3 for Windows and only if Patch bundle is installed before the upgrade. That was exactly my scenario, I installed 11.2.0.3 and then Patch 8.
According to MOS note we can ignore the error if remaining installation steps finish without errors and if components are valid afterwards:

select comp_name,status,version from dba_registry;

After upgrade we must run scripts that’ll rebuild DB Replay repository objects; just to be sure that we remove any depricated data from repository tables:

cmd>@%ORACLE_HOME%/rdbms/admin/catnowrr.sql
