Oracle sql developer ошибка 17002

In this post we’re going to talk about Oracle SQL developer “SQL Error 17002 Sqlstate 08006” error on Windows. We’ll talk about the error code and how to fix it fast.

Why Does SQL Error 17002 Sqlstate 08006 Shows Up?

Most of the times it shows up because there is incorrect Misconfiguration or listener isn’t running. Before you’re able to connect with Oracle database, SQL developer must be configured correctly and listener has to be running. The listener handles databases connection, by default the SQL settings does not need listener for connecting to database and so it has to be configured.

SQL Error 17002 Sqlstate 08006

Another possible reason for this SQL error could be database sessions have been terminated by the network firewall or interrupted by another reason. In this case you have to make sure firewall isn’t stopping idle connections.

Connectivity problems between oracle integration and connectivity agent can be the cause of this error also, or when the connectivity agent is disabled. You have to make sure connectivity agent is running. You can check the status under your Dashboards and Agents in oracle integration.

How To Fix SQL Error 17002 Sqlstate 08006

The fixes to this SQL error code is mostly about fixing or configuring the listener. We’ll also share other fixes that will help.

Fix No.1: Ensure listener is running

This can be checked from Windows Service Manager or using Command Prompt. Follow these steps to check the status;

Checking listener status using Windows Service Manager:

Press Windows + R to open Run Dialogue.
Type msc in the dialogue box.
In the list of services, TNS listener is listed, make sure it’s running, the status is shown beside each service. If it’s not running you just need to right-click and click Start.

Checking with command prompt:

Open command prompt, you can do that by typing cmd in windows search, right-click on it and select ‘Run As Administrator’.

When the command prompt opens, you type this command: C:>lsnrctl status
If it’s not running, error will be mentioned multiple times, and you need to start it.
To start the listener service, you need to type this command: C:>lsnrctl start

lsnrctl status

Fix No.2: Making sure the listener has the right configurations

Open Oracle SQL Developer.
Right click on database name and select properties.
A window will open and you need to take note of the Hostname and port values under the ‘details’ tab.
The default port is 1521, but sometimes it can be 1522, it has to be changed.
Now back to checking hostname, you should type C:>hostname.
The hostname will immediately appear below this command and if you’re receiving the SQL error code 17002, in most cases it will be different from the hostname that appeared when you right-click on the database name in the previous step. Remember that I told you to take note of the Hostname, this difference occurs when the computer name is changed. In this situation, the hostname has to be corrected in the connection Window, and the port value also should be changed to 1521 if that’s not the value.
The next step now is to open tnsnames.ora file and check to confirm that the hostname and port is correct. The full path is; %ORACLE_HOME%/network/admin/tnsnames.ora. if not you need to change the values appropriately.
Open the Windows Service Manager and Restart OracleserviceXE by right clicking and then click restart.
Now you should test the connection to see if things are ok. When you’re sure all values are correct, that’s the Port, Hostname, username and password, you should click the test button. If connection show successful it means the problem has been rectified.
After that you can now click connect and can now browse and query your database.

This fix can be lengthy or seem complex to most users but that’s the way to go about it.

Fix No.3: Restart Oracle TNS listener

As we’ve mentioned in the first fix, you should check whether listener is running or not, so in this case even if it’s running you should restart it. You should follow the same procedure in the first fix. Restarting the listener has work for some, you should give it a try.

Conclusion

So far these are some of the best fixes to SQL Error 17002 Sqlstate 08006, the problem most of the time has to do with listener and you need to ensure that it’s pointing to the correct port and server. Once you can figure this out, you’ll definitely get rid of the problem.

Symptoms

In the process of rolling out banners for SEC_USER_UNAUTHORIZED_ACCESS_BANNER and SEC_USER_AUDIT_ACTION_BANNER.

Testing applications to see if there was any effect on connectivity, and noticed unable to connect to the database using SQL Developer (3.0.04). SQL Developer throws error:

Error
———
An error was encountered performing the requested operation:

IO Error: Got minus one from a read call

Vendor code 17002

Works
————
Using SQL Developer 2.1 connects without any errors
SQL Plus can connect to the database without any issues, as can TOAD
SQL Developer can connect to the database without issues if we remove the banner files.

Does Not Work
—————
Using SQL Developer 3.0 and banner files.

Changes

Upgraded from SQL Developer 2.1 to 3.0.

If you search for the Oracle error “Io Exception: The Network Adapter could not establish the connection” (ORA-17002) you will find plenty of discussion on the web. It usually comes down to what the message says, that it is a network issue. But the error can also be caused by e.g. incompatible jar files. In my case, however, I was trying to access a 11g R2 instance from SQL Developer and during initial setup everything had worked. And local access, also with SQL Developer, worked absolutely fine.

Solution: Replace “simple” DB hostname with the fully qualified one. I am not sure why this changed the behavior. I can think of either a DNS setup issue (although my search list included the domain) or some kind of reverse lookup logic that is being applied. Anyway, I wanted to share this finding and also record it for my own future use.

Thanks for the tip, it worked for me too !!
Even, I changed localhost to my machine name, it worked, and it was still working when I reverted to localhost. There must be some strange network behaviour beneath.

thank you very much!
I tried a lot of complex solutions and this was the winner, now I can continue my work, thanks again

thank you very much …!

other solution :
you make sure that you have the right DNS on your IP Address this is happened if you have 2 network

It didn’t work for me.

Thank you very much, it helped me to solve the problem I had

Thank you so much for your helping me.

it worked fo me too ! merci beacoup !!

Awesome tip! worked for me too…it was a dns issue

Hey, what’s the difference between “simple DB hostname” and “fully qualified DB hostname”? some example pls because I’m not sure did I understand it right? 🙂

Simple name is e.g. “dbserver” whereas fully qualified one is “dbserver.mycomany.com”. Does that help?

Where can I find fully qualified name? I tried with select * from global_name, but I got same name as simple name….

The fully qualified hostname is part of the machine’s network setup and only indirectly part of Oracle

It worked like a charm. Thanks

Awesome tip. It worked for me..

I tried everything, it doesn’t work. Finally i tried by using connection type as local/Bequeath. Then it worked for me.

Other solution: In your application data-source change the connect string from
“jdbc:oracle:thin:@host:port:sid” (short connection string)

“jdbc:oracle:thin:@(DESCRIPTION= (ADDRESS = (PROTOCOL = TCP)
(HOST = host)
(PORT = port)
)
(CONNECT_DATA=
(SERVICE_NAME=sid)
(SERVER=DEDICATED)
)
)” (full server string)

Super… Used the fully qualified hostname and it worked. Thanks.

Thanks worked for me 🙂

Hello All ,
I have tried all these techniques but still my facing same issue.
1- I have data source on my local websphere6.1 and when do test connection from web console server ,it was successful but when i tried to do the same it giving me error
” java.sql.SQLException: Io exception: The Network Adapter could not establish the connectionDSRA0010E: SQL State = null, Error Code = 17,002″

Note : I am connection to remote oracle db.
in my machine , i have only raid & web sphere installed.

Please any body help me.

Advance thank you

It c an be bacause of the wrong credentials of the service name. I changed my system credentials which i was using for the service, the moment i updated that it worked for me. Thanks.

@Lucas Silva: perfect, your my hero!

I got this error but the hostname is the fully one
I changed to localhost and it worked fine

SQL Developer won’t connect to database — Vendor code 17002

I have latest Oracle Sql Developer 3.2.1 installed, and I cannot connect to databases. I typed correct SID, port number, user and password and it won’t connect saying: «The Network Adapter could not establish the connection. Vendor code: 17002»

Do I need oracle client installed on my machine to connect to remote server using sql developer?

I am tunelling the connection using putty SSH to remote machine, and I put localhost as host in connection details in sql developer, but it works on another computer. I have also JDK 1.7.0_06 installed, and while starting sql developer I get warning that this product is supported with minimum version of 1.6.0_04 and less than 1.7. May this be problem?

Thanks in advance
Tom

Answers

Vendor code 17002 generally means a major network problem like invalid host or port number. Using ssh tunneling complicates the troubleshooting. It may be best to try to replicate the other machine setup as far as possible, including ssh setup, name resolution and sql developer configuration.

These are the normal troubleshooting steps.

Given a SQL Developer connection definition of DBSERVER, 1521, ORCL.

Can you ping DBSERVER?
Can you telnet to DBSERVER on port 1521 (telnet DBSERVER 1521). If you don’t have windows telnet you can use a putty telnet session.

I assume somewhere in your tunnelling setup you have something like locahost:1521 mapping to DBSERVER:1521. In that case you can replace localhost in the troubleshooting steps.

ORA-17002 error

I am using Sun JDK for Linux and classes12.zip to connect to Oracle8i 8.1.5 EE Server running on Red Hat Linux 6.2.

It’s a multithreaded application which connects successfully to the database, works fine for some time but suddenly starts throwing ORA-17002.

I am struggling to sort out this error, the JDK version is. Can anyone help ?

Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_02)

Thanks in anticipation,

Hi, I get this too. Win2k to sun solaris 8 (8.1.7) Did anyone find a reason why this happens?

Me too! Relates to ‘java.sql.SQLException: Io exception: End of
TNS data channel’ as the error code of the exception.

I’m on 8.1.7 talking to 8.1.7

I got the same problem, this is sporadic.

Here is what I found:
1) duplicate host name in the host file
2) Oracle thin driver version issues
3) JDBC port blocking, ie 1521
4) SID & service name issues
5) Oracle BLOB issues
6) result set exhaust, close it before re-crate one.

None of them can solve my problem. The error just come out from no-where, and goes away by itself. It is on my production server, so I am getting calls every hour.

I’m getting this error in a multi-threaded application that connects to 9i database. I am able to connect to connect with 25 clients, but several clients will received this message «Io Exception: invalid arguments in call». Each client when done, will make the same call:

cstmt = dbConnection.prepareCall( «» );
cstmt.setInt( 1, getSyncID() ); /* sync ID */
cstmt.execute();

Out of 25 clients, only one or two will experience this problem. The error stack is as follows:

java.sql.SQLException: Io exception: invalid arguments in call

at com.tiscor.syncserver.ServerThread.sync_Logout(ServerThread.java:1149)
at com.tiscor.syncserver.ServerThread.run(ServerThread.java:348)

I’m getting the error when close connection.
