    Q: I have successfully tried using Oracle. connect toSQL developers to seeThis error.

    Vendor code 17002

    Answer: “Vendor code 17002” for youcurrently equivalent to ORA-12541: very likelyA listener failed or a port with the wrong type or service name.From the person’s documents:

    ORA-12541: TNS is not an auditor

    Reason: a listener from a specific source repository was not actually usedstart.Start

    Action: pipe on the device on which the source is locatedRepository.

    How do I fix vendor code 17002?

    Press Windows + R.Sign in to services. msc as Strike Enter.Find all the services you configured with ora, start those services in addition to waiting!If your server specific service is indeed initialized (in my case it was orcl)Now start mysql or whatever you are using and run the code. P.

    Basically, the SQL developer couldn’t find trade show attendees. Check firsttnsnames.ora as well as those who make sure it points to the correct server andHarbor. If the exact form server is on a different device, check the TNS resolution.with


     # lsnrctl status 

    This should indicate the status of the phone and service provider.Listen. Think how many times you have run SQL * Plus for a particular database.Server, no need to connect to earphone unless specified by your entry for the tnsnames database.ora.

    lsnrctl state

    Influence on checking the most importantOn-hook and

    lsnrctl start

    to turn on the headset. WhenIf you are familiar with Windows, also make sure the Listener Service Type is running.

    I faced the same issue with ORACLE 11G on Express Windows.After a long wait, I got exactly the same error message.

    My solution is to make sure the hostname in tnsnames.ora (usually shouldn’t be localhost) and the hostname of the backlog in Developer (usually SQL is localhost) are the same at the shoulder joint. You can do it differently by changing it to tnsnames the.ora and substituting it for the SQL developer.

    How do I set a default connection in SQL Developer?

    Start Oracle SQL Developer locally. The Oracle SQL Developer home page is displayed.In the Connections section, right-click Connections.Select New Connection.In the Select New Connection / Database Connection dialog, create the following databases:Click Test.Click Connect.Open the new connection part.

    Oh, everyone in your category usually needs to restart Oracle services (just in case).

    I came to the market with a similar problem with another machine, but this time the best solution doesn’t work.After several attempts, it was found that restarting all services applicable to Oracle could fix the problem. Initially, when the installation is complete, may be relative. Either way, somewhat immediate computer restarts usually have a problem.I am modifying all Oracle services that need to start automatically. And as soon as I can’t login, I start over from them all over again (the main service must be restarted by the last command) and it works fine.

    some say that this could be due to the problems of MTS. Microsoft problem. May be !

    How do you fix status failure failed IO error the network adapter could not establish the connection?

    Reload with assembly. lsnrctl start “or on a reasonable Windows operating system by starting the Audience service. Add the hostname and IP address to the host music file which is located in the C: Windows folder. System32 drivers etc This might be an Oracle SYS user password issue Check with that specific Oracle DBA to find out the correctness.

    I have version of Oracle Database 12c running on Linux, AWS ec2 instance. When I try to connect remotely from my browser (macOS) to SQL Developer, I get a new I / O error : Network adapter cannot establish connection Vendor Code 17002 error. Usage
