Barry,

         Many thanks for your reply. I managed to sort out the problem a few weeks ago,

and was meaning to post a followon to this thread about the solution.

Essentially,  I was told by my support people that when I created my

database, somehow, 'catalog.sql' was not run on the database. 'catalog.sql' should

have automatically been run at database creation time - I don't know why this didn't

happen.

Now I have run catalog.sql on my database/s and this seems to have fixed the problem.

To run 'catalog.sql' on the database, I have had to do a cold backup of the database

(just for precaution). Then rum the following command after login into thw database

in 'sqlplus'. (as sys user with sysdba).

The command to run is

@C:\oracle\ora92\rdbms\admin\catalog.sql

Thanks for the help again
