Global temporary tables.
Tables, which data is persitent for a transaction or a connection
(depending on the table definition).

Excuse me but what does GTT mean ?
Can you please tell us how did you solve the issue. Could you mend the

It depends on what kind of changes you plan to do. Some of them still

Hello,
I wonder if is it sure to perform changes to the database metadata
while there are still users connected.
Up to now, I allways shut the database down, perform DDL changes, and
put it back on line.

Thanks for any help.
