Hi Experts,
I created a database on my machine. When I trying to start my lsnrctl in Linux machine. I am not able to start it.
here are my files,
listener.ora
[oracle@localhost admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/oracle

[oracle@localhost admin]$ cat sqlnet.ora
# sqlnet.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ADR_BASE = /u01/app/oracle

[oracle@localhost admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

DB11GR2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = DB11gR2)
    )
  )


the below is the cmd i used to start my lsnrctl DB11gR2 and the following error message
[oracle@localhost admin]$ lsnrctl status DB11gR2

TNS-12541: TNS:no listener
 TNS-12560: TNS:protocol adapter error
  TNS-00511: No listener

My database is already running and it's SID is DB11gR2. If I need to create a lsnrctl How to create it.

Thanks in Advance.

listener.ora file is NOT required to start or use the listener.

move, remove, rename, or otherwise eliminate the listener.ora file then do as below

lsnrctl start

COPY the results from above then PASTE all back here

I am good to use the above cmd previously also. My aim is I want to start the lsnrctl specific to Database.
Because my oracle Enterprise manager is not loading the page.

when i used the https://localhost.localdomain:1158/em it's showing a message like below
Failed to Connect

Firefox can't establish a connection to the server at localhost.localdomain:1158.
Though the site seems valid, the browser was unable to establish a connection.

    * Could the site be temporarily unavailable? Try again later.
    * Are you unable to browse other sites?  Check the computer's network connection.

listener should NEVER be "dedicated" to any specific database.
listener should service every instance that runs on the DB Server

>>Because my oracle Enterprise manager is not loading the page.
when listener uses "localhost", then no remote client can ever connect to the listener.

move, remove, rename, or otherwise eliminate the listener.ora file then do as below

lsnrctl start
lsnrctl status

COPY the results from above then PASTE all back here

Do you realize that now this is the THIRD different problem you are reporting?
I fixed the listener problem.
I got you connected via EM.
I suggest that you only use MS ACCESS which is a much more user friendly application.

Normally you do not need to configure listener for connectivity to running db as registration is dynamic.

BUT if you are planning to use ENTERPRISE MANAGER / physical standby etc. -- please add the service name
to the SID_LIST_LISTENER entry ( if not present, plz. add manually to the listener.ora file)

eg. entries of your listener cud be:

LISTENER =
( ADDRESS = (HOST=LOCALHOST.LOCALDOMAIN.COM)(PROTOCOL=TCP)(PORT=1521))
)

##ADD BELOW ENTTRY FOR ENTERPRISE MANAGER TO WORK-- my db name is meruprod.fauna sid=meruprod
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /data/app)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = meruprod.fauna)
(ORACLE_HOME = /data/app)
(SID_NAME=meruprod)
)
)


-- thats all then reload listener/restart it , startup your enterprise manager -- everything will work ok.

How does above have any impact on OP being disconnected after a few minutes?
