Sql developer error 17002 - Исправление ошибок и поиск оптимальных решений проблем

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. Do let us know in the comments if these fixes have solved the SQL error for you, if you also have more ideas to share please drop your comments below for our readers.

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.

No — it was NOT ‘an odd caching issue’. It was what I told you earlier

The results of ‘lsnrctl services’ do NOT show ANY DB registered with the listener. Either the DB wasn’t running or it hadn’t registered.

Answers

If you’re on Unix, the location should be $ORACLE_HOME/network/admin

That exception has NOTHING to do with the listener. Your attempt never leaves the client.

You are calling a number that doesn’t exist.

We can’t help you if you don’t SHOW US:

2. HOW you do it

3. WHAT results you get

You need to show us the type of connection you are trying to create and the parameters you use in the connection dialog to make it.

The hostname, port or SID/SERVICE_NAME you are using are wrong or you don’t have that host name in your hosts file.

Oddly I have another connect which uses localhost, & I get an Error 12505 on that one — tns does not the SID —

Well — that’s your problem isn’t it? This is what I said

Your host name is ‘oracleexpress’ — I don’t see that in your ‘hosts’ file anywhere do you? If the host name isn’t in the file then the JDBC driver can’t find it to get the IP address of the DB server.

Well — local host is in the ‘hosts’ file but what you posted shows you are using 27.0.0.1 as the IP address when the local host address should be 127.0.0.1

If the ‘sid’ can’t be found then the database isn’t registered with the listener. Post the results of

‘lsnrctl services’ and it will show you EVERYTHING the listener knows about.

Most DBs these days register automatically when you start them. So if your sid ‘xe’ isn’t listed the database either isn’t open or the registration failed.

The TNSnames.ORA file is NOT used for basic connections.

Thanks for your reply — but it was my BAD very BAD.

When i pasted the /etc/hosts file — i made two mistakes — I missed the 1 from local host, and when I subsequently pasted the other data, the cursor was in the wrong place. Really sorry about that. for completeness I paste the full /etc/hosts below

Если вы используете адаптер для подключения к экземпляру базы данных Oracle E-Business Suite, эта уникальная ошибка повторяется, проверьте планы Quandary SQL и другие настройки SQL. области работы. ... Адаптер использует JDBC в API-интерфейсах вредоносных драйверов для получения метаданных, таких как новости таблиц, информация о хранимых процедурах и т. д. Это включает выполнение SQL путем запроса драйвера JDBC, что означает таблицы SYS, такие как ALL_TYPES room table . Поскольку Oracle E-Business Suite имеет гигантский словарь данных, запросы метаданных должны решать рекламную и маркетинговую задачу, повышая общую производительность какого-либо адаптера. SQLState: 08006 errorCode: 17002 Сообщение: Ошибка ввода-вывода: время ожидания соединения истекло Эта ошибка должна иметь место, когда сеансы базы данных прерываются любым огромный сетевой брандмауэр или какое-то другое объяснение, почему. Адаптер автоматически восстановится во время округа, и будут созданы новые соединения. Однако для отдельных запросов, использующих предыдущие соединения, может истечь время ожидания. Убедитесь, что эксперты говорят, что брандмауэр больше не прерывает непродуктивные соединения. Тайм-ауты также могут возникать из-за запросов дизайна. Избегайте определенных антимоделей. Например, не создавайте явно ту же таблицу, что и при создании хирургического вмешательства, если страница инициализации может запросить новую такую же таблицу. Сообщение не получено после ожидания X секунд Если вы используете адаптер для подъема в определенное место базы данных Oracle E-Business Suite, в дополнение к постоянным ошибкам проверьте чьи-то планы SQL-запросов и другие аспекты оптимизации SQL. Адаптер использует JDBC в API-интерфейсах драйвера для получения метаданных, таких как табличная информация, сохраненные умеренные данные и т. д. Это требует, чтобы иногда выполнялся некоторый SQL путем поиска в драйвере JDBC, правильное оборудование SYS, такое как таблица ALL_TYPES . Поскольку в Oracle E-Business Suite есть один хороший словарь данных, запросы метаданных должны быть оптимизированы для улучшения общих результатов адаптера.
