Hi,
I have some users that use Oracle connection manager (CMAN) to connect to the database.
Is there a way to identify those sessions from v$session or V$process?

No information about Oracle connection manager in V$SESSION_CONNECT_INFO or in v$process/v$session

Oracle traces everything, how can be possibile that it does not map this information?

It may not be in the database server but the connection manager one.
Oracle Db knows only what the opening connect string (including its associated parameter like IP, machine...) contains. What is the machine name from v$session for these sessions, client or connection manager server?

In machine field on v$session I see the machine name of the user session, not connection manager.

So Oracle correctly passed the information (in my opinion) and it seems it does not want the DB knows it comes through the connection manager.

Why do you need this information, maybe we can achieve your final goal in another way.

I think I can add a rule to oracle connection manager.
Now I do not use rule:
(rule_list=
(rule=
(src=*)(dst=*)(srv=*)(act=accept)
(action_list=(aut=off)(moct=0)(mct=0)(mit=0)(conn_stats=on))
)
)
)

I can add a rule like this:

(rule_list=
(rule=
(src=*)(dst=dbxx-int.dbc.cineca.it)(srv=service_name1_ext)(act=accept)
(src=*)(dst=dbxx-int.dbc.cineca.it)(srv=service_name2_ext)(act=accept)
(action_list=(aut=off)(moct=0)(mct=0)(mit=0)(conn_stats=on))
)
)
)

If I do this, and in v$session I see a session that uses the service_name1_ext, I know it is using connection manager.

Since my two service_name end with ext can I use a single rule like this?

I can add a rule like this:
(rule_list=
(rule=
(src=*)(dst=dbxx-int.dbc.cineca.it)(srv=*_ext)(act=accept)
(action_list=(aut=off)(moct=0)(mct=0)(mit=0)(conn_stats=on))
)
)
)

Oracle 11.2.0.4 on Linux.

It would still be interesting to get an answer to Michael's earlier question ... WHY do you want to know if a connection came via connection manager?

What decision depends on knowing if CM was used by a particular session?

Quite often people spend inordinate amounts of time chasing a technical solution to answer the wrong question.
