I'm not sure why you need this.
The database registers itself automatically with the listener.
If that doesn't succeed, alter system register will do the trick
For static registation in listener.ora you need the SID.
The default SID for non-XE Oracle is ORCL and the default service_name is oracle

  • How to start listener in sql developer for remote debug

    how to start listener in sql developer for remote debug ? Since the new version 1.1.0.23 is different with the old version for remote debug, I don't know how to start the listener on the new version for remote debug.
    even follow the user guide below and not work . Experts on sql developer please help me with this.
    Remote Debugging
    To debug a procedure or function for a connection where the database is on a different host than the one on which you are
    running SQL Developer, you can perform remote debugging.
    Remote debugging involves many of the steps as for local debugging; however, do the
    following before you start the remote debugging: Use an Oracle client such as SQL*Plus to issue the debugger connection command. Whatever
    client you use, make sure that the session which issues the debugger connection commands is the same session which executes your PL/SQL
    program containing the breakpoints.
    For example, if the name of the remote system is remote1, use the following SQL*Plus command to open a
    TCP/IP connection to that system and the port for the JDWP session:
    EXEC DBMS_DEBUG_JDWP.CONNECT_TCP('remote1', '4000'); The first parameter
    is the IP address or host name of the remote system, and the second parameter is the port number on that remote system on which the debugger
    is listening.
    Right-click the connection for the remote database, select Remote Debug, and complete the information in the Debugger - Attach
    to JPDA dialog box. Then, follow the steps that you would for local debugging (for example, see Debugging a PL/SQL Procedure).
    Debugger - Attach to JPDA This dialog box is displayed when you right-click a database connection name and select Remote Debug.
    Use this
    dialog box if you are using the Sun Microsystem's Java Platform Debugger Architecture (JPDA) and you would like the debugger to listen so
    that a debuggee can attach to the debugger.
    For more information about remote debugging, see Remote Debugging.
    Host: Name or IP address of
    the remote host on which SQL Developer should listen for the database to connect.
    Port: Listening port number on the remote host. You can
    choose any valid port number that is not in use by another process.
    Timeout: The number of seconds that SQL Developer will wait for the
    remote database to make a debugging connection. Don't Show Dialog Box Before Connecting: If this option is checked, this dialog box will not
    be displayed before future connections for remote debugging

    You're not the only one:
    Not able to start remote debug listener

  • Problem With Listener Service: Long Delay Starting Listener, Intermittent Connections

    I am having trouble connecting to my Oracle database.  I'm not sure what the cause was, but now when I connect to a database that has been working fine for the past two years, I usually get a ORA-12541 error.
    I run lsnrctl status on the server and get a prinout like this:
    Copyright (c) 1991, 2010, Oracle.  All rights reserved.

       64-bit Windows Error: 2: No such file or directory
    I've also tried manually stopping the service via services.msc and then restarting via lsnrctl start, but when I do this I get a really long delay (10+ minutes) before it returns with something like:
    TNS-01153: Failed to process string: 0í≈♥
    I'm pretty lost as to what is wrong.  I've been messing around with listener.ora, but I don't see anything problematic in there.  Here's a copy:

    TRACE_LEVEL_LISTENER = SUPPORT
    TRACE_FILE_LISTENER = LISTENER
    However, a few times during this I've been able to connect to the server, via sqlplus, but it has taken 10 minutes before the connection comes online.  Once I'm connected, I can query my tables as expected, but I need an application to connect.
    If anyone has any ideas on what could be wrong, please let me know.

    When I opened up netca, I didn't have any listeners configured, which seems very strange.  When adding it, I get this message in the cmd window:

    I killed the service via services.msc again and tried starting the lsnrctl.  This time I've got a new listening service going:

  • Stop and then start Listener from OEM

    Hi,
    I am new to Oracle. I notice after stopping listener using OEM on Windows XP, the TNSLNR.exe is terminated as I expected. At that point, all connections include OEM, iSQL*PLUS and SQL*PLUS should close connection.
    If this is right, how can one start listener from OEM? One needs listener work before using OEM to config something else. What is the purpose of Start button for listener on OEM? Even more perplexing me is that iSQL*PLUS is still works! Does iSQL*PLUS not use listener for connection?
    Your help will be appreciated,
    -Hong

    Hi
    i think its not possible to start the listener from oem, because the oem use the listener to communicate to the db.
    Regards
    Mirko

    Please, if somebody knows this problem I need a very urgent help. Thank you very much.

    Thanks ALL, I GOT IT, but I used other solution.
    Since I installed and uninstalled the Oracle several times, it keeps also many different Services for the listener. I don't know why, it didn't create a Service for my actual instalation with its path. In other words, all the services remained in the services.msc panel, had the path that was already removed from the Windows folder.
    Then what I did, was that I picked one service, took its name (OracleOraDb10g_home1TNSListener), went to regedit to [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\OracleOraDb10g_home1TNSListener] and simply changed the image path that was setted for the one that was removed (C:\oracle\product\10.1.0\Db_2\BIN\TNSLSNR ) for mine that is installed right now
    (C:\oracle\product\10.1.0\Db_1\BIN\TNSLSNR). Nothing more and finally works.
    I have tried something in the services.msc panel before, as you can see in this forum at the thread "I can't start listener in the Control Painel/Admin Tools/ Services", but I never got
    success.
    Appreciate your time!!

  • TNS:protocol adapter error while starting Listener created by Oracle SES11.1.2.2 Setup

  • Reply to : TNS:protocol adapter error while starting Listener created by Oracle SES11.1.2.2 Setup

    To answer the post from Manwendra Jun 20, 2013 7:17 AM
    " TNS:protocol adapter error while starting Listener created by Oracle SES11.1.2.2 Setup "
    https://community.oracle.com/message/11077982#11077982
    Hello,
    Probably that you already have the listener up and running from your installation of SES.
    Also, you could check in your Windows Services (from the Control Panel), you'll see that
    there is a service like OraclesesTNSListener up and running.
    If it is the case, then it's probably why it is telling you the message below when trying to start it again:
    TNS-01106: Listener using listener name LISTENER has already been started
    Then, before trying to start the listener, you can check if it is already up by running the command : lsnrctl status
    If you need to shut it down, then you can run the command : lsnrctl stop
    for example, from the command line:
    > set ORACLE_SID=ASUSES
    > set ORACLE_BASE=D:\ses\
    > set ORACLE_HOME=D:\ses\seshome
    > cd %ORACLE_HOME%/bin
    > lsnrctl status            <== this will give you the status of your listener
    > lsnrctl stop              <== this will stop your listener
    > lsnrctl start             <== this will start your listener
    Hope this can help you and others.

  • Starting listener on OEL5.3

    Hi. I am new to oracle and linux. I recently installed OEL5.3 on my HP dv6536 laptop. During the installation i checked the "oracle validated install" option in the customize packages section. I then installed oracle 10GR2, everything went well. I was able to use enterprise manager and iSQL but i could not launch SQL. when i restarted my system, i typed "lsnrctl start LISTENER", i get an error, saying "command not found". Is there any other way to start the listener or should i manually reconfigure my enterprise linux for oracle? If so please i need the right commands and parameters. thanks.

    Hi and welcome to Oracle world and Oracle Forum :)
    You should know that in order to run SqlPlus or Listener or any Oracle related program, you need to run it from bin directory.
    If you don't want each time to go to bin directory and run them, you should export Oracle home directory and you should add Oracle's bin directory to PATH environment variable
    Let's assume that you've installed Oracle Database in */home/oracle/product/10.2.0/Db_1* directory and your Database name is testdb
    export ORACLE_SID=testdb
    export ORACLE_HOME=/home/oracle/product/10.2.0/Db_1
    export PATH=$PATH:/home/oracle/product/10.2.0/Db_1If you want above codes to be run automatically when you open new terminal, you shoul add those lines to */home/oracle/.basrc* file
    Good Luck

  • Srvctl start listener -n rac1 gives CRS-1028 and CRS-0223

    Boot up 2 linux 10.2.0.1.0 RAC nodes.
    everything starts except listeners
    srvctl start listener -n rac1
    or
    srvctl start listener -n rac2
    gives
    CRS-1028
    CRS-0223
    However, if you start listeners manually, using
    lsnrctl start listener_rac1
    or
    lsnrctl start listener_rac2
    they start right up. Moreover, once you have started them manually, the srvctl start listener commands now work, both stopping and starting the listeners with srvctl now works. However, when reboot systems, again srvctl must be "primed" for starting listener by doing one "manual" startup of listener.
    Any thoughts on what is causing this behavior?
    Thanks!

    Alan, thanks - excellent advice. However, I just ended up redoing the entire install and this of course fixed the problem :-)
    Thanks for your reply, Gil
    PS also, btw I use the crsstat script instead of the crs_stat for better formatting, i.e. this script (which I named crsstat) lives in $ORA_CRS_HOME/bin. Also, note I am not the author of this script, I downloaded it from Metalink:
    #!/usr/bin/ksh
    # Sample 10g CRS resource status query script
    # Description:
    # - Returns formatted version of crs_stat -t, in tabular
    # format, with the complete rsc names and filtering keywords
    # - The argument, $RSC_KEY, is optional and if passed to the script, will
    # limit the output to HA resources whose names match $RSC_KEY.
    # Requirements:
    # - $ORA_CRS_HOME should be set in your environment
    RSC_KEY=$1
    QSTAT=-u
    AWK=/usr/bin/awk # if not available use /usr/bin/awk
    # Table header:echo ""
    $AWK \
    'BEGIN {printf "%-45s %-10s %-18s\n", "HA Resource", "Target", "State";

    state == 0 {next;}
    $1~/TARGET/ && state == 1 {apptarget = $2; state=2;}
    $1~/STATE/ && state == 2 {appstate = $2; state=3;}
    state == 3 {printf "%-45s %-10s %-18s\n", appname, apptarget, appstate; state=0;}'

    srvctl stop listener -n rac2 -l ora.rac2.LISTENER_rac2.lsnr
    Node1: rac1

    Same i have to follow to start listener , start word in place of stop , right?.
    Please confirm me on this.
    Thanks,

    This is 2 node RAC on ASM with single standby on ASM.
    To stop listener in all RAC nodes , are the below steps correct?.
    crs_stop ora.rac1.LISTENER_rac1.lsnr
    crs_stop ora.rac2.LISTENER_rac2.lsnr
    OR
    srvctl stop listener -n rac1 -l ora.rac1.LISTENER_rac1.lsnr
    srvctl stop listener -n rac2 -l ora.rac2.LISTENER_rac2.lsnr
    Node1: rac1
    Node2: rac2
    Same i have to follow to start listener , start word in place of stop , right?.
    You should use the second option using srvctl.
    Because srvctl is meant for starting/stopping resources.
    Even using first command also you can achieve this and also using lsnrctl also. But I would prefer srvctl.

    This sounds like you have created a startup-exe for your cRIO. So this is what you do if you want the cRIO to run independently from your host. This is what you do if you want the cRIO to start working as soon as you power it.
    Running a VI from your LV project on the cRIO is for debugging. So if an executable is running on the cRIO, it will have to terminate before you can run the debugging version of the VI.
    So regarding what you want to have, you either have not to run the application as startup-exe at all or you must not connect to the cRIO using your LV project.
    If you choose to keep the rtexe, you will have to implement an interface to it in order to exchange data with your host. You should take a look into the cRIO reference architectures for ideas for possible solutions. This reference architecture shows a quite good solution....
    hope this helps,

    beg you for help???
    thanks very much.

    It sounds like your environment isn't set up, e.g. ORACLE_HOME, etc.
    However you should post your question to the database forum.

  • Why does my iphone 5 automatically revert to shuffle when I start listening to music after sitting overnight?

    I am playing through my music collection alphabetically at work. But, when I stop listening at the end of the day and then start listening at the beginning of the next day, my iPhone starts shuffling instead of continuing alphabetically. Anyone else having that problem? Any ideas why it is doing that?

    My new iphone 5 shuffles all the time even when the shuffle icon isn't selected.  It's driving me crazy I can never listen to the song I want to hear.  On my created playlist it won't play any song it just shuffles through all of them list wise then goes back to the main menu having not played even one song.  I'm so frustrated I could scream.  Something is worng some sort of software glitch.  I never had this problem until I got this new phone two weeks ago.

    i am unable to start listener thats why the connectivity problem so jst suggest me brother wat to do to start listener
    thanks a lotFirst Carefully do it.
    Step 1:
    Go to network configuration assistant.
    Delete existing listener and then after deletion
    Go to add new listener and after listener added
    Go to Local net service configration assistant and add and give service name (your oracle sid) and give your host name (host name should be your computer name or ip address of your computer ) and after add it you should test it whether you can connect your database or not.
    If you cann't connect,
    Go to
    Copy of your database tnsnames string ORCL Ex:\D:\oracle\ora92\network\admin\tnsnames.ora and
    past it to tnsnames of devsuite ex:\c:\devsuite\network\admin\tnsnames.ora
    Copy of
    %oracle_home%\network\admin\tnsnames.ora open it and copy your database string.
    ORCL =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = mazar)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = orcl)
    and then paste it to %dev_home%/network/admin/tnsnames.ora
    after paste it
    go to ping tnsping orcl. You can sure your oracle service is started here
    if its ping , you should check listener also .lsnrctl>status
    I'm sure ,if you're do properly follow above steps, you can connect easily.

    Hi,
    Chek did you set your LD_LIBRARY_PATH variable or not.
    set it correctly..i.e
    export LD_LIBRARY_PATH=$ORACLE_HOME/lib
    where $ORACLE_HOME is also set to your oracle installation.
    mail me back in case problem persist..
