Hello,
Our database network analyst has detected some strange characters within our calls to the database as follows:
There are symbols such as @, >, ; and spaces where they possibly should not be.
EXAMPLE:
--------
Begin :ret := XXXX.XXXX(:v1, :v2, :v3, :v4, :v5, @:v6, :v7, :v8, :v9, :v10, :v11, :v12, :v13, :v14, :v15, :v16, :v 17); End;
Please note the "@:v6" and the ":v 17". Note the "@" symbol in the first one and the " " space in the second one...
ANOTHER EXAMPLE:
----------------
Begin :ret := XXXX.XXXXX(:v1, :v2, :v3, :v4, <:v5, :v6, :v7, :v8, :v9, :v10, :v11, :v12, :v13, :v14); End;
Please note the "<:v5" where the "<" symbol is!?!?
Can anyone explain this? I have posted on numerous sites and looked for answers on the web with no results.
If anyone could help me this would be greatly apreciated.
Cheers....

Hello,
This is not hurting our prcedures or calls by the applications (As far as I know) but our DBA is very concerned and requests that we find out why these chracters are there.
Other databases have within our department that are very similar have been sniffed and their results do not have these characters. Why?

Hi Michel,
These are very good questions:
Different versions or so.
--------------------------
No because we all ahve the same version on all of our database servers.
Why are they concerned?
-----------------------
Because our database is a lot slower than all of the rest.
What are their concerns?
------------------------
Their concern is that maybe this malformatted string or buffer if you will may be slowing down the calls to our database.
Why are they sniffing?
----------------------
Our database network analysts always sniff the lines 24/7 and then send the results to the DBAs. I don't know why... Maybe because of hacking?
Hope this helps....

Hi Michel,
It's really nice here. We've had a crazzy winter though!! Lots of Snow out here!!
Well there's lots of stable government work out here for software people like us.

And clients?
---------------
The clients also have the exact same version. See we are all in an Intranet environment and all of the client computers are updated through the network. So you can assume they all have been upgraded at the same time (or when the user reboots)...
Do they know the SQL*Net packets format?
---------------------------------------------------
I would assume taht they do but I do not know what "SQL*Net packet format" is....
How can they be allowed to do this?
-------------------------------------
Since we are on an Intranet environment with no outside activity I think it is fair to say that this is not an issue.
Cheers....

Hi,
I am still looking for an answer as to why we are noticing weird characters (@, >,  within our database packets....
EXAMPLE:
------------
Begin :ret := XXXX.XXXX(:v1, :v2, :v3, :v4, :v5, @:v6, :v7, :v8, :v9, :v10, :v11, :v12, :v13, :v14, :v15, :v16, :v 17); End;
Please note the "@:v6" and the ":v 17". Note the "@" symbol in the first one and the " " space in the second one...
ANOTHER EXAMPLE:
----------------
Begin :ret := XXXX.XXXXX(:v1, :v2, :v3, :v4, <:v5, :v6, :v7, :v8, :v9, :v10, :v11, :v12, :v13, :v14); End;
Please note the "<:v5" where the "<" symbol is!?!?
Any help would be greatly appreciated....
Thanks...
