Why Does Discoverer Create
Two Dedicated Connections?
A couple of
people
recently asked the question
on the OTN Discoverer Forum:
"I am
new to Discoverer tool
as such. Therefore I
have this question, pl
pardon me if it very
basic.
When I use the desktop
edition of Discoverer to
make a connection to the
Oracle db. One the
database side, it
creates 2 dedicated
connection for that
Discoverer session. Is
this normal, so
something is not right
in my environment
configuration."
and
"I've
recently started using
Discoverer and I too
have noticed this
'feature'.
I have a vanilla
Discoverer 4.1 Client
Installation on NT,
without tweaking any of
the defaults. I'm sure
our DBA's would like to
know why there are 2
sessions - and if this
can be configured (i.e.
reduced)."
The reason
you have two dedicated
connections is because
Discoverer makes two
connections to the database
- one to the End User Layer
tables, and one to the
source database tables
themselves.

Requirements for
Discoverer".
