Please show us exactly how you are trying to connect. Is it through a remote client? Copy and past both commands issued and errors.

Hi Phiri,

It's not client-server. I'm directly connecting to the database from the server itself.

Well
first "ORA-12154: TNS:could not resolve the connect identifier specified" occur for you because
you acn not set ORACLE_SID env variable fist SET ORACLE_SID=<SIDNAME>

second "ORA-12514: TNS:listener does not currently know of service requested in connect" for
this you must register service in listener as static or dynamic

for example add to listener.ora file such as

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = SB)
(ORACLE_HOME =

\oracle\product\10.2.0\db_1)
(SID_NAME = SB)

)

then
lsnrctl stop
;lsnrctl start; and try connect again

Can you connect your db?

Oracle is ALWAYS client-server. Even when client and server are on the same computer.

(Even the memory-only 'Bequeath adapter' mechanism is client-server.)

The use of double-quotes implies that you learned this several versions ago. Has not been required for several versions.

Try

$ sqlplus / as sysdba

(and note the space after the '/'. Not absolutely required but highly recommended.)

Listener does not 'try' on a different port.

However, (under normal circumstances) when listener forks/execs the server process AND that new server process is instructed to use the TCP/IP protocol by the tns substrate due to configuration (even when on local environment), the new server process will open a new TCP port for communication and the listener will tell the client to communicate on that.

Hey DBA84,

He is trying to connect the database locally.Then no concerned with listener here.

Even if the listener is down also,he can able to connect to the database.

Listener comes into picture when you are connecting remotely.

KSG:set the oracle_sid & try to connect.

khaja

if you use sqlplus > connect username/[email protected] then must use listener ok?
