Look at the list of required init.ora settings to be applied after migrating/upgrading
an Apps 10.7/11 database to 8.1.7 when upgrading to Apps 11i ! [pasting from the Apps 11i Upgrade manual]

Set init.ora file parameters
In your init.ora file, set the following parameters to the values indicated. Restart
your database for the new parameters to take effect.

          after these changes all the dynamic views created by developers
          have stopped
          working .

          our database is running on aix 4.3.3 and its in MTS mode .

          Will appreciate quick response.

          thanks in advance .
