Thanks Wayne. This a great idea to prevent user activity on the server. I’ll use it in the future. But I’m looking for a way to prevent user activity on a database ((i.e. "database" being a "schema" or a "catalogue). David.

Do your data load and then set you max_connections back to what it was prior. show variables like ‘max_connections’; (note this number) set global max_connections = 0 This will leave 1 connection open for a superuser, I dont know what ID you use for that a lot of people use root. Now import your data. Once the import is done set global max_connections back to what it was.

(i.e. "database" being a "schema" or a "catalogue). At the beginning of the import script, we first drop all objects in the QA database so that it will be a perfect match (object wise) to production. Is there an easy way to lock the whole database for the duration of the import - so that no developers can update the database? Obviously, I can revoke permissions, but I was wondering whether there is a better approach.
