Db problem

[alan_131]

I have 1 listener called by my applications when i'm trying to connect via SQl/NAV.
I want to add another listener w/o affecting the other listener that i have created.
How will I add a new listener?


thanks

regards

Hi

Listeners will already be there (oracle will tuned to this). just make sure listerner are up and running
$lsnrctl
lsnrctl> status

will show the listener status.

You want another listener to listen to the same instance or is it another instance??

If you want to create another listener for another instance, go to $ORACLE_HOME/network/admin, open the tnsnames.ora and listener.ora and add what's necessary.

Hi

If you like you can add another listener into your $ORACLE_HOME/network/admin/listener.ora. This can then be started and stopped independently. e.g. lsnrctl start

Hope This Helps

I want to add a new listener for new instance.
I 've already add the new instance in the listener.ora and configdured evrything in the tnsnames.ora. When i tried starting the default listener by the command - lsnrctl start, listener started properly, but when i tried to start the new listener for the new instance, it states that " Listener using listener name LISTENER has already been started"

how can i start 2 different listener in one server. By the way i'have added the new listener value in the listener.ora file.

Alan,

In tnsnames.ora:

= (DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1531))
(CONNECT_DATA=(SID=))
)

= (DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1531))
(CONNECT_DATA=(SID=))
)

In listener.ora:

=
(ADDRESS_LIST =
(ADDRESS= (PROTOCOL= IPC)(KEY= ))
(ADDRESS= (PROTOCOL= TCP)(Host= hp440)(Port= 1531))
)


SID_LIST_ =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME= hp440)
(ORACLE_HOME= /.../product/805) -- My RDBMS is 8.0.5
(SID_NAME = )
)
(SID_DESC =
(SID_NAME = extproc)
(ORACLE_HOME = /.../product/805)
(PROGRAM = extproc)
)
(SID_DESC =
(ORACLE_HOME= /disc2/app/oracle/product/805)
(SID_NAME = )
)
)

STARTUP_WAIT_TIME_ = 0
CONNECT_TIMEOUT_ = 10
TRACE_LEVEL_ = OFF

LOG_DIRECTORY_ = /.../product/805/network/admin
LOG_FILE_ =
TRACE_DIRECTORY_ = /.../product/805/network/admin
TRACE_FILE_ =


Hope this'll help!

When you added the new listener value, did you put it as a separate listener or as another SID in the default listener section. See the following listener.ora example for adding a new listener call newdb:

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = db01))
(ADDRESS = (PROTOCOL = IPC)(KEY = db02))
(ADDRESS = (PROTOCOL = IPC)(KEY = db03))
(ADDRESS = (PROTOCOL = IPC)(KEY = db04))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(ADDRESS = (PROTOCOL = TCP)(HOST = ????)(PORT = 1222))
)
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/product/8.1.7)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = ????)
(ORACLE_HOME = /oracle/product/8.1.7)
)
)

NEWDB =
(ADDRESS_LIST =
(ADDRESS=
(PROTOCOL=ipc)
(KEY=????) )
(ADDRESS=
(HOST = ????)
(PROTOCOL = TCP)
(PORT = 1234)
)
)

The new listener can then be started separately using lsnrctl start newdb
N.B. Ensure that your new listener is using a different port number.

Hope This Helps
