• FRM-10142 the http listener does not work on the name of the computer to the port 80

  Hello

  During the race, the oracle 12 c form a following error message

  FRM-10142 the http listener does not work on the name of the computer to port 80. Please start the receiver or check your preferences of runtime.

  Sandy

  First, you will need to check the SST is running.

  go to admin server url in your browser, click on the target icon that is left top of your admin home go to the http server and then start your ohs1.

  and open your generator of forms go to the updated runtime default url like e.g. OSH, you can find your url such as http://localhost:7777 or http://localhost:7779.

  your full url looks like this format http://localhost:7777/forms/frmservlet or http://localhost:7779/forms/frmservlet.

  Localhost can be your default ip 127.0.0.1 or any static ip 192.0.0.10 address in this format.

• frm-10142 http listener does not

  Hi all

  I am unable to run any form of generator of forms, I get the error frm-10142 (http listener does not)

  tried different ports (8888, 9001, 7001)

  When I connect to the console like this:

  http://127.0.0.1:7001 / console

  and click on deployments (11.1.2) formsapp is listed with the new State

  When I click on environment = > servers the following is listed:

  Name State listening Port

  AdminServer (admin) being RUN 7001

  STOP WLS_FORMS 9001

  STOP WLS_REPORTS 9002

  When I connect to the EM with http://127.0.0.1:7001 / em

  and under Farm_ClassicDomain, I open the forms node, and then click Forms

  then, in the form of deployments, it is empty

  the weblogic server is running

  OS: 64-bit windows 7

  forms: 11.1.2.2.0 64-bit

  WLS 10.3.6

  could it be caused by a recent update for java 8? (java version = 1.8.0_60)

  any ideas?

  If you want to start the console servers, nodemanager must be running.

  Go to you $DOMAIN_HOME/bin folder and user batch file to start servers:

  StartManagedWebLogic.bat WLS_FORMS

  You will be asked for weblogic credential.

  Last output message should be something like this: "server started in OPERATION."

  Then you can try to access the forms.

• ORA-12505, TNS: Listener does not currently of SID in the connection descriptor (code: 2 011)

  I get this error when you try to create a data store for Oracle database of the Disqualification.

  ORA-12505, TNS: Listener does not currently of SID in the connection descriptor (code: 2 011)

  I am able to connect to this database by using the same credentials through SQL, but the Disqualification, I'm not. Do I need to do anything in linux server before the implementation of Oracle data warehouses?

  Thank you

  Ravi

  There are a number of ways.

  1 use a JNDI connection configured in WebLogic and select by name

  2. use the LDAP connection or TNS - see http://docs.oracle.com/middleware/1213/edq/DQEXT/config_dbase.htm#DQEXT202

  3. Add an oracle.xml file in [local disqualification home] / dbconnectors with the following content. This will allow you to select the service name in the standard Oracle data store wizard:

  Class = "com.datanomic.utils.databasespecies.species.Oracle"

  MaxNameLength = "30" invalidnamechars ="" ' >

  Hello

  This time the Sql developer is connected successfully. But there is not a question of being happy because what happens frequently. Sometimes is connected while sometimes the connection refused... All, it seems, is that SQL Developer connection to the Oracle server depends on luck.
  Is there any solution to get rid of this problem?

  It's a matter of timing.

  First thing that should be launched is the listener. Who should be started on boot. For a laptop or another machine which uses the DHCP protocol, the listener must be configured to talk to the loopback adapter.

  Then the database should be started to talk to listening on the port of sight to the listener - it is applied either with the "LOCAL_LISTENER" database being left to null (for the default listener on 1521). This can be checked by "Lsnrctl status" showing the instance of database such as saved and available.

  Then the SQLDeveloper can start up, pointing to the same host, port, and service/instance, as shown in "lsnrctl status".

  Thanks in advance
  Mourad

  Hello

  Make sure that you use right tnsnames.ora as you have it installled oracle developer suite after installation of the database so it could change your ORACLE_HOME as a result of developer. You have 2 choices

  1. replace oracle_home installation of oracle database in the variables env control panel system
  or
  1 copy the tnsnames.ora, listener.ora under Developer suite... location/networ/admin.

  If you are using on your local computer, you do not have this and you should be able to connect but if you use it is not bad either.

  Output from the following command post

• Listener (and the database instance) does not start automatically: ORA-12514: TNS:listener does not currently of service requested in connect descriptor

  Hi all... I am a newbie with oracle database.,.

  I have the problem of monitoring:

  I installed Oracle Database 11 g R2 XE on my CentOS 6.5 guest operating system.

  I changed the host name in my CentOS so (where installed oracle 11g R2 XE) after the installation was completed successfully.

  Installation-) before and during the hostname is localhost.

  (-) After the installation, I changed the host name in VMCentOS

  From the moment where I changed the host name, nothing starts automatically. In particular, the listener and the database instance does not start automatically.

  When I start the listener manually and I try to connect to the instance of database with SQLPLUS I get this error:

  ORA-12514: TNS:listener is not currently of service requested in connect descriptor

  I think that the problem is due host name changed because I have to test and debug the object, re-installed a machine virtual operating system CentOS, re-installed oracle database 11 g and I do not have this problem. The database instance and the listener starts automatically!

  Can someone tell me if, maybe, the problem is with the host has changed? ... and why?

  P.S.: After changing the hostname I also modified the listener.ora and the tnsnames.ora by changing the HOST with the correct host name.

  Hello

  It seems that you don't install Oracle Database Express Edition (XE). If you post this question in the wrong forum.

  When you install EA or there is no script that starts the database at startup.

  If you wish, you can create by yourself. For example search for instructions to Google how to create script.

• listener does not start after upgrading clusterware

  Hello. RHEL 5, updated the clusterware 10.2.0.5 RAC to version 11.2.0.4 grid (database version is always 10). After the reboot, a node is OK, but on another auditor does not start. If trying to run manually, it starts with the error "the listener supports no services". After comparing with another node, it seems that 'bad' node uses old file listener.ora, which is now 0 bytes (probably was allowed during the upgrade):

  You need to check first, which is not running and why (. / crsctl res stat - you), a lot of resources are dependent on network net1. Start by watching clusterware alertlog and check the config network of the second node. If the basic config is very good, you can try with netca or command line (oifcfg, iflist,...).

  However, the Blog does not include my dynamic qurery can return records 10000 +.

• Keyboard event listener does not work in the browser

  Is there a reason why a keyboard event listener would not work if the flash is embedded in an HTML element? The rest of my game runs well in the background, but I can't launch the movieClip "nextCar." My code is below, if that makes a difference...

  goNow function (event: KeyboardEvent): void {}
  thisOtherKey = event.keyCode;
  If (thisOtherKey == 32) {}
  nextCar.gotoAndPlay (2);
  parkingQue.play ();
  tent ++;
  }
  }
  stage.addEventListener (KeyboardEvent.KEY_DOWN, goNow);

  This is perhaps a silly question, but have you tried to click on your swf file once it opens in the browser and then try the keyboard controls?

  I don't know any problems that may cause debugging workwhen event listeners, but not in a browser.  So I think that maybe your just not well centered on the swf.

  Hi all I got this 12505 error today when you try to start sql developer. I tried browsing the forums for a possible solution, but none were found that workes on my pc.

  OS: Windows 7 Home Premium *.

  NO Oracle version is already certified or supported on any Windows Home Edition.
