Some coworker told me that login triggers actually
store things on disk instead, and that every time this
stored info is needed, a disk access will have to occur instead,
and that doesnt sound too great of a concept...

Does anyone who used login triggers extensively
have any knowledge and/or opinion to share?

thanks,

Maa,
 It is a great concept,,, store everything in memory and eliminate
disks. with enough memory you could store the info each user needed.
 If the user is going to request the same info each time why not use
materialized views to increase the thru put.

We have a fairly big query that takes about 6 hours
to complete. To speed up things, we thought of the
following: Create a logon trigger, which stores in memory
each user's info during login time.

Then when the user clicks a button that starts this query,
to have his/her info already in memory as opposed to
getting it from disk somewhere.

So basically, I just wanted to verify that a login trigger
does indeed store things in memory and keeps it there
until logout. Is that correct, or should I expect surprises?

thanks,
maa
