Shared server config issues

Question

Dear experts,
Below is my environment details:
DB: Oracle 10gR1 Base (10.2.0.1)
OS: RHEL 5
I have configured shared servers as shown below:
1) Set the following parameters
dispatchers='(protocol=tcp)(dispatchers=2)'
max_dispatchers=10
shared_servers=4
max_shared_servers=10
circuits (not configured)
2) Changed TNS parameter as below
I modified SERVER=DEDICATED to SERVER=SHARED
3) lsnrctl services
the output of this command shows dispatchers ready
Now coming to the issue, when i connect to the database using new tns alias, i see "NONE" displayed under "SERVER" column of the V$SESSION view. It should have been SHARED.
Appreciate your help in this regard.
Thanks
P

In Shared Server configuration when we see value 'NONE' , it means there is no task being processed by shared server for that session. The server column will infact show status of 'SHARED' if there is some task being processed at that particular time by the shared server process for that session. Hence to check the status, fire some big query and then check the server status .
you can check the shared server as
select server from v$session where machine='XXXX' ;--neeraj
