Hi,
I have configured the gateway listener and tnsping works fine but when i fire "lsnrctl service <listener name>" it gives below output with refused connection.
can anyone please help me identify the issues?

    I read from some forums that I need to edit somethings of which am not really sure cos i don't wanna mess with the database, I need help on what to.
    Thanks for help in advance.

    Use a single listener. There is no need for multiple listeners 99.9999% of the time.
    Have the listener bind the hostname as listening end-point - and not localhost.
    Localhost only allows local processes to connect via TCP. Which is questionable in most environments. Typically you would run clients on other h/w platforms (or VMs) - and this will use the database server's public IPs.
    Type hostname in the console to get the hostname of the server. If the network on that server is suspect (was not manually setup properly by someone knowing network basics), do not bother using the hostname. Use IP address +0.0.0.0+ instead.
    Update the listener.ora file. The LISTENER entry should look something as follows:
    LISTENER =
            (DESCRIPTION_LIST =
                    (DESCRIPTION =
                            (ADDRESS_LIST =(ADDRESS = (PROTOCOL = IPC)(KEY = EXTERNAL)))
                            (ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = <hostname-goes-here>)(PORT = 1521)))
            )You can also simply (and safely) remove/rename the listener.ora file - and start the listener with sane defaults.
    Next, use sqlplus (via the oracle o/s user) to logon as SYSDBA to the database. The database parameter of interest is LOCAL_LISTENER. It should be null (view it using the SQL*Plus command <i>show parameter</i>). If your listener port is 1521, then not a problem.
    If it is not, you need to update/set this parameter with the appropriate port number via the ALTER SYSTEM command.
    Once set/checked, manually instruct the database to register its services with the local listener, via the alter system register command in sqlplus.
    Check and confirm that the listener has received and successfully serviced that registration request by typing lsnrctl services in the oracle o/s console.
    PS. The reason for the error I think is that your are forcing the listener on localhost only - while the default/null local_listener parameter of the database instructs it to contact the listener on the default public IP address of that server. Which does not happen to be localhost IP 127.0.0.1.

    Did you try a tnsping to see if it can provide name resolution? Can you connect to the database using the connect string service name such as sys@pussdb? These would indicate whether the database has been properly defined in your databse names resolution method (e.g. tnsnames).

  • Listener drops suddenly or refuses connection

    I am having some strange problems and need some help ASAP.
    I have an Oracle 7.3.4 database running on AIX 4.3. Now the listener sometimes suddenly stops for no apparent reason or refuses connection requests to the database leading to
    ORA-12203 TNS: unable to connect destination
    errors even though on checking the status of the listener it indicates that it's still up.
    Now does the SNMP setting affect the operation of the listener in any way. It's currently set to ON.
    Thanks all.

    Yes I do. infact i have spent virtually the whole day stopping and starting the listener. Haven't left my desk at all.
    Before it ran almost uninterrupted but now i have to constantly monitor it. Sometimes it works, sometimes it doesn't.
    when i restart it, i have something like this
    cmsxd has i service handler(s)
    even before i restart my Pro*C application cycle, the number of service handlers begins to rise and always hits a maximum of 13 after which it doesn't rise anymore. There is nothing happening as yet but it still rises. If a service handler is a db instance registered with a listener and i only have one db instance i.e cmsxd, why would i have 13 now?
    I do not know what these service handlers or db instances are. The lsnrctl status command does not give a detailed breakdown of these service handlers.
    when i type lsnrctl services i get the ff output
    Services Summary...
    cmsxd has 13 service handler(s)

    I hope you could help me how to fix this problem. I think this problem happen related with the tns listener for the new oracle 10g. I was try to reconfigure the port,but that's didn't work.

    [oracle@myoramachine ~]$1. Check lsnrctl services <listener name>
    2. Check tnsping output:
    tnsping MYORACLE
    3. Check connectivity to the machine where your Oracle Server resides to port ( I assume 1521):
    telnet <your_machine> 1521
    4. In case you're not able to connect to the Oracle Server - I'd investigate it in a few directions:
         - network infrastructure problem
         - some disturbing process(es) / virus(es) on Oracle Server itself
         - firewall issue
    Good luck!

  • Parallel execution of scenarios errors with Listener refused the connection

    When we are trying to run large number of sessions in parallel, ODI is erroring out with the following error.
    Caused By: java.sql.SQLException: Listener refused the connection with the following error:
    ORA-12519, TNS:no appropriate service handler found
    at oracle.odi.jdbc.datasource.LoginTimeoutDatasourceAdapter.doGetConnection(LoginTimeoutDatasourceAdapter.java:133)
    at oracle.odi.jdbc.datasource.LoginTimeoutDatasourceAdapter.getConnection(LoginTimeoutDatasourceAdapter.java:62)
    at oracle.odi.core.datasource.dwgobject.support.OnConnectOnDisconnectDataSourceAdapter.getConnection(OnConnectOnDisconnectDataSourceAdapter.java:63)
    Please find the detailed log below.
    It looks like we have exceeded the total number of database sessions set at the db level.
    But do we have a mechanism to configure the ODI in such a way that the sessions wait until the database sessions are available for use.
    For e.g. if we have 2000 as the db limit and the number of parallel sessions to be invoked is around 3000, how do we configure the ODI to wait for the sessions to be freed so that all the 3000 sessions can be run successfully instead of erroring out.
    Can this limit be set at ODI agent level (by setting Maximum number of sessions parameter)?
    How do we set this for a local agent (i.e Default agent).

    Hi,
    [oracle@myoramachine ~]$ oerr ora 12505
    12505, 00000, "TNS:listener does not currently know of SID given in connect descriptor"
    // *Cause:  The listener received a request to establish a connection to a
    // database or other service. The connect descriptor received by the listener
    // specified a SID for an instance (usually a database instance) that either
    // has not yet dynamically registered with the listener or has not been
    // statically configured for the listener. This may be a temporary condition
    // such as after the listener has started, but before the database instance
    // has registered with the listener.
    // *Action:
    //  - Wait a moment and try to connect a second time.
    //  - Check which instances are currently known by the listener by executing:
    //    lsnrctl services <listener name>
    //  - Check that the SID parameter in the connect descriptor specifies
    //    an instance known by the listener.
    //  - Check for an event in the listener.log file.
    [oracle@myoramachine ~]$1. Check lsnrctl services <listener name>
    2. Check tnsping output:
    tnsping MYORACLE
    3. Check connectivity to the machine where your Oracle Server resides to port ( I assume 1521):
    telnet <your_machine> 1521
    4. In case you're not able to connect to the Oracle Server - I'd investigate it in a few directions:
         - network infrastructure problem
         - some disturbing process(es) / virus(es) on Oracle Server itself
         - firewall issue
    Good luck!

  • After rebooting:Listener Refused the connection:ORA12519

    Hi There,
    Let me brief you first how this prob arises:
    I had run RCU for creating database schemas ......for that i have change my system processes to 300 to run RCU properly....
    IT worked fine but after rebooting my system...when i try to connect the db thru sqldeveloper... i am getting the error"Listener Refused the connection:ORA12519,TNS no appropriate service handler"......for which i have consulted the
    ORA-12519 using thin JDBC client this forum one of the post suggested that change process to 150....
    Now i have three points:
    1.Can i also alter my system processes to make it work fine...?
    2.Currently as i am trying to connect thru JDev it is throwing me an exception " Listener refused the connection with the following error:
    ORA-12505, TNS:listener does not currently know of SID given in connect descriptor"... I guess this prob is due to aforesaid issue and it will work once the instance is up.....
    3.I have shutdown and startup my DB in cmd and it gives me message database mounted and opened .......does it means that db is working fine but still it wont be able to connected coz of process...
