Thanks Raj for the Global Temporary Tables' Advice.
Only 3 Tables hold the login info. Each Table has only 1 or 2 indexes.
These are small Tables with a few rows being inserted / updated into each
table per user login
Database will be a RAC Setup.
Approx a Total of 30,000 Concurrent users will login to do a set of OLTP
Transactions for an upcoming Benchmark.
If you could clarify what sys_context & VPD meant?
Any Docs, Links?
Regards

you can use GTTs, they can be made session specific. However, you might
pay a performance penalty if you over index them and if this is RAC, never
ever try to truncate them. They will do all you want. GTTs are a good thing
when used in moderation.
OTOH, if the data is small (i.e. few rows) have you considered using
sys_context? Tom (of askTom fame) has a bunch of examples of using
sys_context especially when he shows VPD.

Folks
On login by a User into our Hybrid Banking Application certain session
information e.g. role of user, operational authority of user etc is
INSERTED into a few Tables which needs to be preserved only till the life of
the respective user login session i.e. till the User logs OUT.
Additionally on a Database re-start we would prefer the respective tables
to get automatically Truncated/Flushed but with the Table Structure &
corresponding Indexes continuing to exist. We would prefer NOT to manually
create the Table Structure & respective indexes on DB restart.
NOTE - Both Dedicated & Shared Servers Database connections are used.
Currently PERMANENT Tables are being used for the same
*Qs Can some types of Temporary tables be used instead in Oracle – 10.2?*
NOTE – Redo need NOT be logged for these Tables.
Thanks indeed
