RE: disabling a role via a logon trigger

Jeffrey - I'm going to suggest something simpler. It may not work in your environment. An end user should not have the password the application is using. I have many third party applications here. Normally there is an application administrator. I will share the password with that person with the understanding that they will not share it with anyone else. If an end user needs to use SQLPlus or another application, then I create them a separate login. Consider just changing the application password and not giving the password to anyone else.

That would mean having to setup a policy on every table in the system.

I hope this cak help you solve this. Take a look at Metalink note# 67977.1. It talks about Fine Grain Access Control (FGAC). The note also gives some examples on how to set it up, which isn't very complex.

I thought I came up with a solution to this by disabling the role if the the terminal running the application is not one of the servers we expect, i.e. if the connection
was via sqlplus from a users PC, the terminal id would not match and I would disable the role. If the user was granted other roles to view the
tables, those would remain, just the update role would be disabled.

However, I now find that a database "on logon" trigger can not disable a role. The procedure that I was calling from the trigger to do the disable had authid current user but the problem is the trigger.

Is there any way to disable a role from a trigger, or is there some other way I can disable the role. We do not want users being able to update tables outside of the application.
