Had this as our security guys implemented an Application Gateway
(Juniper)
between our Servers, dropping Connections. Do you have
such boxes in place ?

regards

BINGO!

Do you have a solution....?

You can try setting up Oracle Connection Manager and bypass the firewall.

How would that help? By the way we are using Standard Edition. I have no
idea what this means - if you have a firewall how can you "bypass" it?

Say the network is like this:
+-------+
Quote:
db11g |
+-------+

-----
firewall-1
-----
Quote:


i n t e r n e t


----
firewall-2
----
Quote:
+-------+
db10g |
+-------+

firewall-1 appears to be the issue

if i understand our sec team, this was a 11g protocol
issue not handled correctly by the app gateway, basically i
dont care about issues introduced by other teams , only have to
q.e.d. but could asked them tomorrow. Dont know about your org,
but if local works and remote not it indicate net issue.
Your net team should provide the solution.

regards

stefan

Paul, connection manager is a proxy server on the firewall itself or with
a tunnel that would make it possible to control the database connections.

our Sec team have disabled the protocol inspection
leaving port redirection etc. untouched.
