Installing Oracle Applications R12.1, Tip #4

Make sure you have your OLAP workspaces defined before you attempt the 12.1.1 upgrade portion.  Otherwise, you will get an error similar the below when running MSDODPCODE.sql:

ORA-37002: Oracle OLAP Failed to intiialize.  Please contact Oracle OLAP technical Support
ORA-33262: Analytic Workspace EXPRESS does not exist.

To fix:

sqlplus "/ as sysdba"
@?/olap/admin/olap.sql SYSAUX TEMP

Then you can restart your worker using adctrl.
