Sorry Jack,
I didn't preserve the title ... it was copied from an internal email. Also the _ parameters are never documented in official ora docs, Metalink is good for that.

Hi,
With the way we have implemented FGAC, we do not have any parses
occurring with application context.
The application context does act like bind variables and I will try to
illustrate that with an example.
We set the context of the users logging in to a particular group/role
which gets executed

Jack,
This is from TFM ...
Starting from 9i, queries against Fine Grained Access enabled objects always execute the policy function to make sure most up to date predicate is used for each policy. For example, in case of the time based policy
some other people were saying if you use it with a 'context' it binds it.
is that accurate?

My understanding was that the rls predicate was added
at parse time (hence the importance of the contexts
and avoiding things like 'sysdate')
But also if I remember correctly, this behaviour was
changed in v9 to process the security function with
each execution (and hence probably increase the am

None of that implies it's not appending a where clause like it
was explained.
It uses the context values (if that's the case) in a function
which then returns a string. Tha
Hi Raj,
Vadim is right and if RLS is implemented without application context then
there would be hard parses especially if there are literals in the policy
function . We have a client warehouse with about 500 users and 300 tables
and FGAC has been working very well and we do not see latch waits.

This is interesting do you know where it is documented quickly? I'll do a rtfm/stfw in the mean time.

I've
developped 3 functions for fined-grain access control and the users have tested
them.
There
are only 3-4 users in the acceptance env. and I did not noticed
anything.
What
version are you running and how many users ?
We're
on 8172

Raj - In this case, RLS would be Row Level Security?
