ODBC error - no tns listener,  when trying to connect to database

I have installed Personal Oracle9i in Windows 98 operating system. I am unable to connect to the database using ODBC. I get error TNS-12541 TNS: no listener, even though i configured tnsnames.ora and listener.ora using Net Configuration Assistantand Net Manager. The destination entries in both files match. I get the same error even when I try to do a tnsping on the database name. How do I start the listener with the database already running?

There4s not enough to configure your tnsnames.ora, sqlnet.ora and listener.ora, you must enable the listener to run in your machine, in other O.S. like Workstation or W2000 you can do it "starting services", in W98,
you must run regedit and locate a line that references the listener, must be "AUTO" in that record.
Other way it4s edit your autoxec.bat and add the following line
LSNRCTL START

  • ORA-03113 when trying to connect to database

    I've currently a 7.1.3 client on SUN Solaris (5.10 Generic_118844-26 i86pc i386 i86pc) where I want to connect to the 9.2.0.6 database on a Win2003 Server hardware.
    When i try to connect via SQL*Plus (Release 3.1.3.4.1), I get ORA-03113. Looking into the listener resp. alertfile on the server, I can see that the connectiorequest is recognized, but immediately answered by an ORA-0600, producing also trc-files.

    Can anybody help me in determining the problem ? Is there a systemtic incompatibility in connecting a 7.1.3 client to a 9.2 (or even higher) database ?

    Thanks for your reply.
    But the funny thing on this compatibility issues is, that this configuration worked before. The only thing we did, was to setup the client-PC on a new hardware with also a new operating system (upgrading from Solaris 5.8 to 5.10). And from that time we encountered this problem.
    Are there any OS-related problems known or better to say: is (was) ORACLE 7.1.3 supported on Solaris 5.10 ? Should we look for any patches which might help us ?

  • Dreamweaver CS6 - Get error when trying to connect to database..

    When trying to connect to a database in Dreamweaver CS6 - I keep getting this error... 'An unknown error has occurred'.  I've exhausted all google hits.. and have tried EVERY combination possible during the past 4 years... SOS - please help me..  Thanks!

    Moving it yet again to the correct Dreamweaver forum: Developing server-side applications in Dreamweaver.
    Usually, "an unknown error has occurred" means that there's something wrong with your testing server definition. Have you followed the instructions here: http://www.adobe.com/devnet/dreamweaver/articles/setup_php.html ?

  • Ora-12154 when trying to connect to database from fortran application

    I am trying to connect to database and run an simple select query to a table(without any where clause) using pro*fortran code.
    the connect strng is like
    exec sql connect :uidpwd
    where uidpwd = username/password@SID
    SID and tnsnames connect string are the same.
    The fortran (profortran) code is placed in the database server and there are no errors when make is run.
    Tnsping is working fine, also i am able to conect using sql*plus and run the same query.
    Please help
    Thanks and Regards
    Nitin

    Hi Nitin
    Thanks for the helpful! With your point I'm now Pro! Great thanks.
    By the way have your seen that?
    Files such as LISTENER.ORA, TNSNAMES.ORA, SQLNET.ORA, if configured manually, or copied and edited from earlier releases of Oracle Database may have record attributes that are incompatible with Oracle Database 10g release 2. The software cannot read such files. The required record format is stream_lf and the record attributes are carriage_control and carriage_return.
    This may result in:
    Inability to start the listener
    Services not registered with the listener
    Inability to connect to other databases
    ORA-12154: TNS:could not resolve service name
    Run the following command on each file affected:
    $ DIR/FULL filename
    An output similar to the following may be displayed:
    Record format: Variable length, maximum 255 bytes
    Record attributes: Carriage return carriage control
    If the output includes the preceding entries, then run the following command:
    $ CONVERT/FDL=SYS$INPUT filename filename
    RECORD
    CARRIAGE_CONTROL CARRIAGE_RETURN
    FORMAT STREAM_LF
    ^Z
    Otherwise herewith an interesting metalink note. Doc ID:      Note:437597.1

    Many thanks in advance for your advise.

    me, too.
    I installed Oracle 10g for windows on PC1
    and Developer/2000 Forms 5.0.6.8 + sql*net client 2.3.4.0.0 on PC2
    When I tried to connect to database by using SQL*Plus 3.3.4.0.0 the first time to connect is ok (but not fast as normal situation)
    after disconnect the SQL*Plus and tried to made another connection immediately, the [ORA-12637 packet receive failed] appears.

  • ORA-12705 when trying to connect to database

    I am trying to install SQL Developer on a user PC in my company, but when the user tries to connect to a database he gets the following error message:
    An error was encountered performing the requested operation:
    ORA-00604: error occurred at recursive SQL level 1
    ORA-12705: Cannot access NLS data files or invalid environment specified
    0604. 00000 - "error occurred at recursive SQL level %s"
    *Cause:  An error occurred while processing a recursive SQL statement
    (a statement applying to internal dictionary tables).
    *Action:  If situation described in the next error on the stack
    can be corrected, do so; otherwise contact Oracle Support.
    Vendor code 604
    I have tried searching this forum and the rest of the web for this error, and I have tried all the tips that I have found, but nothing seems to work for me, I get the same error message every time. Most of the tips have been centered around the NLS_LANG parameter. Does anybody have a suggestion?

    I have already seen this document and tried it out, but it didn't work. And I have tried out numerous other tips that I have found in different places on the web.
    Is the client installation of any relevance? I notice that this user has a different installation from the one that I have, and that he amongst other things doesn't have sql plus installed.

    If your testing server is XAMPP or MAMP, you should put your site files in the htdocs folder of your local testing server.
    C:\xampp\htdocs\YourSiteName
    C:\mamp\htdocs\YourSiteName
    If you use WAMP server, you should put your site files inside www folder.

  • Error -2096 on Mac when trying to connect to iTunes Store

    For at least two months, my computer has not been able to log in to the apple store. I keep getting the message "error (-2096)". I have talked to many apple store representatives who have asked me to delete and re-download iTunes, which has not helped. Some have given me the tutorial for Windows, and that obviously did not help either. I think I could be something to do with my ISP address, but I have no idea how to go about fixing that. The main iTunes store page shows up with the available music, etc. but I just can't log in or buy anything. So frustrating! anyone who knows how to go about fixing this, please help! Thanks.

    If you can't remember your answers you'll have to reset them.  See https://discussions.apple.com/docs/DOC-4551.

    You can run the net8 assistant to set up your tnsnames.ora file.
    start/programs/oracle/network administration/net8 assistant
    When you are done it should look something like this:

    Have you recently patched/upgraded? This sounds like there might have been a problem relinking the executables / libraries, and/or a permissions problem. For example you may be referencing a 32 bit library with your 64 bit client.
    I believe I recently read a similar case - check Metalink for this symptom.

    I get error message 42032 when trying to connect an iPhone to iTunes. Any ideas how to fix it?

    Did you already try these suggestions?
    Check USB connections
    Related errors: 13, 14, 1600-1629, 1643-1650, 2000-2009, 4000, 4005, 4013, 4014, 4016, “invalid response,” and being prompted to restore again after a restore completes.
    If there’s an issue with the USB port, cable, dock, or hub, or if the device becomes disconnected during restore, try troubleshooting the USB connection, then troubleshooting your security software.
    To narrow down the issue, you can also change up your hardware:
    Use another USB cable.
    Plug your cable into a different USB port on your computer.
    Try a different dock connector (or no dock).
    Add (or remove) a USB hub between your device and computer.
    Connect your computer directly to your Internet source, with no routers, hubs, or switches.
    If you checked your connections and are still seeing the error message, check for hardware issues.
