JDBC Connection Error ORA-12514

Hi all,
I am trying to connect to an Oracle database on my workstation. I am
running Red Hat WS 4.x.
The odbc string I am using is this:
jdbc:oracle:thin:@//localhost:1521/danoracle
I am getting the following error:
Error getting JDBC connection using driver
'oracle.jdbc.driver.OracleDriver' to database at
'jdbc:oracle:thin:@//ddschwitrh4.er.xxxx.gov:1521/danoracle' for user
'satin': java.sql.SQLException: Listener refused the connection with the
following error:
ORA-12514, TNS:listener does not currently know of service requested in
connect descriptor

It looks like the spam filter does not like the copyright line of the output in both commands.

Connection error ORA-12514

Ive recently installed Oracle 10g on my Windows XP and was able to connect.
When i did a shutdown immediate and tried to connect again as a sysdba i get an error:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
Did a few basic checks like Oracle services, listener and all seems up and running. As im studyin Oracle 10g currently, please explain me in simple language meand guide to what i should do to resolve this problem. Any help is much appreciated!

Sorry I did understand your question after I replied.
As for your first point. Output in Command Prompt

==================================================
Also i get the same error when i connect via the web to iSQL Plus
Asfor your second point, Yes all is in Started status even after stopping the Listener and my services for 'OracleServicesORCL' Still same error as above in my command prompt and via web too.
A question for you, in my TNS file you can see my ' (SERVICE_NAME = orcl)' and in my LISTENER file 'SID_NAME = PLSExtProc'. Do these two have to match when the listener listens for a connection?
Any fix for my ongoing issue??. Thanks for your effort.

Java.sql.SQLException: Listener refused the connection with the following error: ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

Good Day,
I'm encountering this problem
     java.sql.SQLException: Listener refused the connection with the following error:

Hyperion startup error -ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

Hi All,
While restarting the hyperion service we see this exception. Nothing was changed on the hyperion server. Checking with DB team if anything was change on their end.

We don't have oracle client on our end, so this is not a tnsnames issue. This is preventing all the hyperion services coming up.
Thanks,

The listener is up , the message is from the listener indicating the listener does not know of SID/SERVICE name that you are giving it. Manually connect to the db using sqldeveloper in order to make sure the parameters you are providing are working. Pay special attention to SID vs SERVICE_NAME. Then try to open config tool and go back to your database connection info. Reconfigure your database connection. It will likely you will find your connection error there. Also sometimes the config tool has trouble figuring out whether you mean SID or SERVICE_NAME. You can open advanced properties on the connection in configtool and specify / or : in the url.

10g Installation and Error : ORA-12514 : Listerner cant recog. service requ

Hi,
I installed 10g, and trying to start sql plus. I entered
username: orcl
password: my own password
host string: name of my computer
I am getting the error: ORA-12514: TNS: Listener does not currently know of service orequested in connect descriptor.
I started the services and tried again but same problem.
I also tried system and sysman as username, w/o a password and included my computer name, but still facing the same problem.
Any thing else I should do besides uninstalling and reinstalling ?
Thanks

Where did the user name orcl come from? It certainly is not going to be there unless you logged in with a DBA account and created it: Did you?
So back to basics ... what version of Oracle did you install? 10g is a marketing label not a version number. It is likely something between 10.1.0.2 and 10.2.0.4.
Second how did you install the database? With the Oracle Universal Installer or with a script? Were there any error messages?
Have you checked the installation log?
Has it ever worked in the past and is now broken or has it never worked?
Is the listener running? How did you check?
When you say "I started the service" you are in what operating system and you started what service and how?
My guess, and it is only a wild guess given how little information you provided, is that there is an issue in your listener.ora and/or tnsnames.ora files: Post them along with the value you are entering as "Host" when you try to log in.
Again just a guess ... the user name should be SYSTEM, the password whatever you entered, and the Host "orcl."

I created Stby DB with the minimum parameters required, so that I configure BROKER and see it magic, but badly stuck in this situation here. I have read many docs related to this..but can not fix it unfortunately.
Please guide me from your own experience as note ids, blogs are not helping me here...
Bundle of thanks.

Hi,
Your listener.ora file has SERVICE_NAME = dg_db2.domain whereas tnsnames.ora file has SERVICE_NAME = dg_db2.
Check in your database for exact service name and reflect the same in both the files.

Restart the listener and try connecting.

Cause
Oracle Workflow software was installed but the packages/repository have not been created.
RPE-002053 indicates that Oracle Workflow Installation is incomplete and OWF_MGR schema should not be empty.
Solution
1) From Oracle Workflow ORACLE_HOME:
- Run $ORACLE_HOME/wf/install/wfinstall.csh
- Follow Oracle Workflow Configuration Assistance screen to install Workflow packages under OWF_MGR schema.
2) Review if there is any error after running the script.
3) Re-deploy OWB Process Flow.

Deployment Error ORA-12514

I have the following problem:
After a failed deployment the deploy status of the project is failed, with the error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
I'm using Oracle 10g Release 1 and Oracle Warehouse Builder 10g Release 1
I've read several threads already about the same error message, but none of the provided solutions worked for me. I've checked the tnsnames.ora files for the service names which should be correct. The runtime repository connection I've created should work because I'm able the start the editor for the runtime repository connection.
Anyone got any suggestions for what the problem could be?
MIS-a

Hello,
Have you looked at the TNSNAMES.ORA file in the ORACLE_HOME of the instance where your OWB Runtime is installed?
Check that the registered location (in Deployment Mgr) of your target matches the TNSNAMES.ORA entry and also matches the real target instance location.
I believe that the runtime environment instance's TNSNAMES.ORA is used to resolve the registered target location, not your design client TNSNAMES.ORA.
[Last minute addition: It might be the design repository instance you need to check, not the runtime repository - we have all in one instance, so I'm not sure exactly where the target location is resolved]

ADF: Gracefully handling JDBC connection errors? Part II

Hi gang
I while back I posted a forum post to find a solution to "display a specific web page when the JDBC connection drops out on our ADF application, specifically the following error: oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection"
...you can see the original post here:
Re: ADF: Gracefully handling JDBC connection errors?
For the life of me I can't get this to work now. It appears I can't redirect to another page during the call to reportException. I've had a play with different methods of redirecting, as seen in the following code sample:
public class ErrorHandlerImpl extends DCErrorHandlerImpl {
public ErrorHandlerImpl() {
    super(true);
@Override
public void reportException(DCBindingContainer dCBindingContainer, Exception exception) {
//    try {
      String message = exception.getMessage();
      if (message.indexOf("JBO-26061") >= 0) {
        // Method 1
        FacesContext fc = FacesContext.getCurrentInstance();
        UIViewRoot viewRoot =
        fc.getApplication().getViewHandler().createView(fc, "faces/errorPage.jspx");
        fc.setViewRoot(viewRoot);
        fc.renderResponse();
        // Method 2
        // FacesContext fc = FacesContext.getCurrentInstance();
        // fc.getApplication().getNavigationHandler().handleNavigation(fc, null, "goError");
        // fc.responseComplete();
        // Method 3 - required IOExcepition handler
        // FacesContext.getCurrentInstance().getExternalContext().redirect("faces/errorPage.jspx");
      } else
          super.reportException(dCBindingContainer, exception);
//    } catch (IOException e) {
}... with no success.
Has anyobody any other solutions or advice on getting this to work?
Your help appreciated.
Thanks & regads,
CM.
PS. JDev 11gR1 ADF BC + ADF Faces RC

Hi Frank
Yep, I' tried redirect, that was method 3 (you can see all 3 methods I've attempted, last 2 are commented out).
With the declarative ADFc exception handler, problem is it's a catch all, not specifically for JBO-26061. Can you think of a way I can tailor fit it for JBO-26061 with a custom message "Database down"?
In addition the exception handler is not consistently called. As example, if you're moving between pages rather than operating on 1 page, the standard af:messages error dialog is shown if the db connection has been dropped, rather than navigating to the exception handler page. As such it seems the DCErrorHandlerImpl.reportExceptions is the better chokepoint to work from.
Cheers,
CM.

Your listener.ora file doesn't list any db services, so you must be depending on database self-registration with the listener, and given that it "used" to work, I assume that self-registration is fundamentally working.
Is it still broken? If so, note what ORA-12514 means. (You <b><i>did</i></b> look it up, didn't you??)
"TNS:listener does not currently know of service requested in connect descriptor"
So, on the database server, what do you see when you check the listener status?
c:\lsnrctl statusIt should list a service that matches the "service name" in the relevent tnsnames.ora entry on your client machine.
You mention this is on "Vista". Please note that no Oracle rdbms product is certified on Vista Home_anything.
Also, your subject says product = rdbms80, but then say you are running 10g. Which is it?

TNS listener error "ORA-12514: TNS:listener..."

Hi all,
I have a problem with my listener on Oracle 11.2.0.2.
I am more of a developer than a DBA, and I do not have a DBA to consult, so I hope you can address me, please.
I have 2 DB instances running on the same machine ORCL and ORCL2 on port 1521, both using the same listener "LISTENER" as well on port 1521.
In my TNSnames I had to add yesterday as well a new entry to a DB (ORCL3) hosted on a different machine.
Since then, I can connect to ORCL and ORCL3 without problem via sqlplus, but I get the below error when I connect to ORCL2:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
I think the answer is to have to separate listeners for ORCL and ORCL2, but I have had several failed attempts.
Can you please advise on what I need to do? I have looked at various sites, but if you are not too experienced with listeners, they are not really very clear.
Thanks

Hi, thanks.

JDBC connection error -- unknown SID

Hello,
I am trying to run my first JDBC application (using the thin driver) -- the Oracle DMLSample example. But I am getting a connection error related to SID:
"Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor The Connection descriptor used by the client was:(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(PORT=1521)(HOST=127.0.0.1))(CONNECT_DATA=(SID=dmsdm)))"
Here is my setup:
I have started the listener -- here is the result of "lsnctl start" command:

The application is built with JDevloper and tries to connect to the DB (located on the same Linux machine where the Oracle installed) with the following parameters:

My questions:
1. What is wrong/missing in my setup?
2. In case I don't remember the SID -- how can I find it?
Thanks very much!
Mark.

Mark,
You asked:
What is wrong/missing in my setup?Possibly nothing. My guess is the problem is with your code. Excuse me, but I couldn't find that in your post.
You also asked:
In case I don't remember the SID -- how can I find it?In one of the data dictionary views. The Oracle documentation will tell you which one.
(I don't remember right now.)
Note, however, that the connection URL you use in JDBC may contain either the SID or the service name and you have posted the service name, namely:
(SERVICE_NAME = XE)For your information I have Oracle database express edition (XE) installed on my Windows machine. The connection URL I use to connect to the sample HR schema is:
jdbc:oracle:thin:HR/hr@//localhost:1521/XEIf you haven't already done so, I recommend reading the Oracle documentation first, in particular the JDBC User's Guide and Reference.
Good Luck,
Avi.

ADF: Gracefully handling JDBC connection errors?

Hi gang
We've a use case to display a specific web page when the JDBC connection drops out on our ADF application, specifically the following error:
oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection.
I've been researching solutions to this and came up with a near solution of placing the following entry in the application's web.xml file:
<error-page>
<exception-type>oracle.jbo.DMLException</exception-type>
<location>/MyErrorPage.jsp</location>
</error-page>This works okay but is a blunt mechanism as it captures all DMLExceptions which includes insert/update/delete failures, as well as the JDBC connection drop out.
Has anybody come up with a better solution for handling JDBC connection drop outs?
Thanks & regards,
CM.
PS. (JDev 11g build 5188, ADF BC + ADF Faces RC)

Thanks John, that's the solution. For some reason I'd forgotten that DCErrorHandlerImpl exists in the controller layer, not the model layer, so it makes perfect sense to override it and do the redirect.
Here's what I came up with:
@Override
public void reportException(DCBindingContainer dCBindingContainer,
                            Exception exception) {
    try {
        String message = exception.getMessage();
        if (message.indexOf("JBO-26061") >= 0) {
            FacesContext.getCurrentInstance().getExternalContext().redirect("faces/ErrorPageJDBCFailure.jspx");
        } else
            super.reportException(dCBindingContainer, exception);
    } catch (IOException e) {
}The following OTN post shows some other methods to do the redirect: JSF forward Vs redirect
Cheers!
CM.
