Question

I’m currently learning database administration on Oracle 11g product and I have some problems :

1) When shared served is activated, we necessarily need two listener I’m right ? One for client’s connection to the dispatcher and another for admin task like startup, … ? (It’s not possible to start a server when connected to shared server, I’m right ?)

2) On the client side, how can I indicate wich listener he must use ? I understand it’s with de tnsname.ora file, but how can I set up It on the client station ?

Thanks.

Answer 1

You must added (SERVER=DEDICATED) to your tnsnames record
and you can run administrative task in your database

BASE1 =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = host)(PORT = port))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = *SERVICE_NAME*)
      (SERVER=DEDICATED)
    )
    )

(SERVER=SHARED) – for shared connections;
