Getting TNS-1150 error

Question

The tnsname.ora file is
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
The listener.ora file is:
LISTENER_RMSDEV =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.187.152.109)(PORT = 1525))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.187.152.109)(PORT = 1523))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/OracleDB10g)
(PROGRAM = extproc)
When I start the listener LISTENER_RMSDEV, it starts successfully.
But when I start the listener SID_LIST_LISTENER it throws this error:
LSNRCTL> start SID_LIST_LISTENER
Starting /oracle/OracleDB10g/bin/tnslsnr: please wait...
TNSLSNR for IBM/AIX RISC System/6000: Version 10.2.0.4.0 - Production

TNS-01150: The address of the specified listener name is incorrect
Listener failed to start. See the error message(s) above...
LSNRCTL>
What can be the possible reason?

Answer 1

SID_LIST_LISTENER is a list of SID that the listerner will be serving, so if I want to have more than one database that use this listener I could do this
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = hr2)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_DESC =
(SID_NAME = hr)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
And I'll be using this listener for PLExtProc (process need for the database) and two databases HR and HR2, when you use lsnrctl start LISTENER it will look inside $OH/network/admin for any file callet listener.ora and will start the listener acording to the info contained in that file.
Hope this helps.
