Can somebody help me
How can I block users from connecting to the database by sql assistant ?
You could set a workload management filter rule that prevents execution of any SQL from application name SQLA.
That's not quite preventing logon, but may be good enough .
Thanks for your reply Fred,
But in this case, I have to avoid users connections to the database.
You can also use Sessions - Query Sessions to filter/throttle sessions based on Application in Request Source
