Hi....
I am trying to connect the database through connection string but it give me an error :

TNS: listner failed to start a dedicated server process

I have created listner :

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = JAGJEET)(PORT = 1522))
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = db1)
(ORACLE_HOME = D:oracleora90)
(SID_NAME = SIDDB1)
)
)

and then created service :

abc =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(Host = JAGJEET)(Port = 1522))
)
(CONNECT_DATA =
(SERVICE_NAME = db1)
)
)

but i am continuously getting error.

One of my collegue has created a listner and a service. When I am trying to connect through his service then it is perfectly working.

Please tell me what is the problem.

Thanks.

Hi,

Looks like your listener is unable to start a
shadow process to process the incoming connection.
Please look at your listener.log file. You should see
the above error as well as a Windows operating system
error. Please post the OS error here so we can try to
assist you.

BTW: Next time, please post SQL*Net related questions
to the SQL*Net Forum.

Best regards.

Frank
