Log of bequeath connection

Question

Hello All,
We are known for that listener will no longer be used for oracle database connection
if the connection is being requested from the server itself, it's called "Bequeath" connection.
I am searching such a log(something like listener log) which is maintained for "Bequeath" connection.
Can anybody suggest me how can I get the log of each "Bequeath" connection in a particular oracle database server.
Thanks in advance and Best Regards,
Suresh Gautam

Suresh,
If it is for an auditing purpose, you could look into Fine Grained Auditing.
With auditing from the database level it would be possible to log session connects.
And with fine grained auditing you could write a procedure which would read the userenv context and you will notice that the IP is null for an bequeath connection.
I do not have an example at hand for this.
but look on otn for the FGA documentation for your oracle release.
for oracle 10.2.0.4 you could start by reading [Fine grained auditing (Security Guide)|http://www.oracle.com/pls/db102/to_URL?remark=ranked&urlname=http:%2F%2Fdownload.oracle.com%2Fdocs%2Fcd%2FB19306_01%2Fnetwork.102%2Fb14266%2Fauditing.htm%23DBSEG525]
SELECT sys_context('USERENV', 'IP_ADDRESS') FROM dual;[syscontext (SQL Reference)|http://www.oracle.com/pls/db102/to_URL?remark=ranked&urlname=http:%2F%2Fdownload.oracle.com%2Fdocs%2Fcd%2FB19306_01%2Fserver.102%2Fb14200%2Ffunctions165.htm%23SQLRF06117]
If you do not need this for auditing then i have no idea ;)
