Hi,

We're trying to prevent users from connecting to our production database via "illegal" connections (i.e. tools like TOAD, etc.).

Does anyone have any suggestions on how to block connections from query tools (i.e. Toad, SQL Nav, etc.) in such a way that an error message is reported back to the tool user that the connection is prohibited? We've tried designing a logon trigger with a PRAGMA definition but the error message is not getting relayed back to the client.

As always, your feedback is appreciated!
