Subject: 8.1.6: possible to set role in db's logon trigger?


Greetings all,

I'm trying to support a COTS application that is back-end agnostic & makes
only minimal use of security on the db.  In particular, it requires that
users be granted a default role that has *very* heavy permissions--enough to
do some major mischief should they ever figure out how to use odbc or
sql*plus.

My collegues & I have devised a kludgy method for getting around this
problem, involving a shill startup program that turns the default-ness of
the role on & off in conjunction with users opening & closing the client
program.  This works, but is a pain to maintain.

I've recently discovered the v$session.program field & am now wondering
whether it would be possible to use the new-fangled logon system trigger to
set the role only for cases where v$session.program = the COTS client.

Can anybody comment as to whether this is a viable approach on an 8.1.6
database & if not, on a 9i db?

In particular, there are two things I don't know--first, how to select just
the one row in v$session that corresponds to the current connection.  If a
user was to start up the COTS client & then connect to the same db via
sql*plus, I would want the role set *only* for the COTS client session.  My
best thought so far here is to use the most recently started connection
based on v$session.logon_time.

Second, whether the SET ROLE statement is legal in a logon trigger.

All help will be most welcome.

Thanks!

-Roy
