Hi,

We got a cluster configuration with something like 500 tables. Sometimes 
we have to add columns to tables. Today we're using execute script which 
locks all tables and not only the tables that belong to the set 
specified in this command. We have a lot of DML statement and these 
locks are really disturbing our application.

Are there other possibilities of using EXECUTE SCRIPT ? Is there a bad 
and a good use of this command ?

Thanks
