I am getting problem in connecting to my database in Oracle SQL Developer. Whenever I try to connect to my database, it gives me this error:
An error was encountered performing the requested operation:
IO Error: The Network Adapter could not establish the connection (CONNECTION_ID=CUJgpQYpQbOXdhiXCUyR3Q==)
Vendor code 17002
Actually, I just use Oracle SQL developer to learn about queries running on a database. I have been using this database since a month but suddenly this error appeared now when I try to connect to the database directly or even manually. Please help me. Any help will be highly appreciated. Thanks in advance.
This is the screenshot for further details:
I tried to do it through an SSH tunnel but stuck there also.
I am trying to connect to an Oracle DB server from Apache superset. When I test the connection string it throws Driver unable to load.
I have even done installation of cx_oracle.
The most common problem when trying to connect apache superset to an Oracle DB is that apart from the cx_oracle library in the python part, you need to install the Oracle client library in the machine with superset. Refer to Oracle documentation and other Stackoverflow threads on how to do this.
Is it possible to create a connection to OBIEE from Oracle SQL Developer?
I know it is possible to create an ODBC connection to the Oracle BI server within the Windows ODBC Data Source Administrator, and that other ODBC client tools can use that ODBC connection to run SQL against the BI server, but I don't see any way for SQL Developer to use that ODBC connection.
I'm on OBIEE 12.2.1.4 and SQL Developer 17.3.0.271.
UPDATE
Based on Robin Moffatt's article at https://rmoff.net/2016/03/28/connecting-to-obiee-via-jdbc-with-jisql/, I used jisql (https://www.xigole.com/software/jisql/jisql.jsp) to set up a connection to OBIEE using the JDBC driver that ships with the OBIEE client -- bijdbc.jar, which is located at $ORACLE_HOME/bi/bifoundation/jdbc/.
Following is a screenshot showing how jisql is able to successfully connect to my OBIEE server via the bijdbc.jar driver and run an example SQL statement; the Oracle-specific connection details are outlined in red:
Screenshot 1: OBIEE JDBC connection test using jisql
My next step was to try to implement this same successful JDBC connection in SQL Developer. To that end, I added bijdbc.jar to SQL Developer's third-party JDBC drivers:
Screenshot 2: bijdbc.jar added to SQL Developer third-party JDBC drivers
After adding the JDBC driver, I did not see a new tab in SQL Developer's connection dialog. (By comparison, in the past, when I have added other third-party JDBC drivers, such as the jTDS and MySQL drivers also seen in screenshot 2, new tabs had become available.)
Since there was not a new tab in SQL Developer's connection dialog, I tried setting the Oracle tab's connection type to Advanced and inserting the JDBC connection string as the Custom JDBC URL. Testing that connection leads to a "String index out of range: -1", as seen in this screenshot:
Screenshot 3: Error using custom JDBC URL in SQL Developer
Since that same JDBC connection string works in jisql, I suspect that either I'm doing something wrong, or SQL Developer does not support connecting to OBIEE via that bijdbc driver.
Ok, fair enough. Have a look at what Andrew did to make the ODBC drivers usable in Excel - it's basically down to manipulating things in Windows:

Just adding a final answer here in case anyone stumbles upon this page asking the same question:
No, SQL Developer does not currently support connecting to an OBIEE server, although other tools can be used to connect to the server using either ODBC or JDBC.
I am trying to make a connection to Cloudera VM 5.10(CDH 5.10) hue hive interface sample database to test the right driver using dbVisualizer tool (https://www.dbvis.com/download)
I checked CDH 5.10 has hive version 1.1, I got this information from
I tested two drivers
1) Hive JDBC 1.1.0 standalone from
https://repo1.maven.org/maven2/org/apache/hive/hive-jdbc/1.1.0/
2) "hive-jdbc-1.1.0-cdh5.10.0-standalone.jar" directly getting from cdh VM.
Cunnection URL I am giving is :
jdbc:hive://http://127.0.0.1:10000
When I connect I get this error message
"An error occurred while establishing the connection:
The selected Driver cannot handle the specified Database URL.
The most common reason for this error is that the database URL
contains a syntax error preventing the driver from accepting it.
The error also occurs when trying to connect to a database
with the wrong driver. Correct this and try again."
Please let me know if I am doing something wrong here.
I am running Neo4j 2.1.6, tried Neo4j 2.20 as well.
I can not connect it with DbVisualizer 9.1.13
And I can not find ANY step by step clear explanation on how to do it.
First I've got binary JDBC Neo4j-2.0.1-SNAPSHOT here
I can run my just installed Neo4j instance from the browser localhost:7474
and I don't know what the REST API is all about and if it is turned on by default.
I can run the Neo4j 2.20 same way that comes with a new feature of user authorization and I am not sure if that JDBC driver is compatible with it. My user:pass is neo4j:neo
So in DbVisualizer I clicked Tools->Driver Manager and filled out like this:
My connection properties are as follows:
I've got the error on connect:
Product: DbVisualizer Pro 9.1.13
Build: #2310 (2015-01-11 11:26:27)
Java Version: 1.8.0_25
OS Name: Windows Server 2012 R2
An error occurred while establishing the connection:
The selected Driver cannot handle the specified Database URL.
The most common reason for this error is that the database URL
contains a syntax error preventing the driver from accepting it.
The error also occurs when trying to connect to a database
with the wrong driver.
If you look at the documentation for the jdbc driver, you see that the database URL is:
jdbc:neo4j://localhost:7474/
Please try to make it work with 2.1.6 first.
For the 2.2. auth you have to use the token you got back as password.
