Where does Oracle SQL Developer store connections?

Question

I have an application that I can't get connected to my Oracle Database 11g Express Edition. I created a test database in this edition, and I can connect to the database fine using Oracle SQL Developer, create tables, views etc. However, I'm having a hard time getting connected via my application. Where is the connection information? In what file? I wanted to compare my connection info with what is set up in the SQL Explorer's file. I found all the *.ora files and renamed them to see if I could find what file (through the process of elimination) the connections were stored in, but I wasn't successful. Any help would be appreciated.

Answer 1

It was in a slightly different location for me than those listed above

\Users\[user]\AppData\Roaming\SQL Developer\system3.2.20.09.87\o.jdeveloper.db.connection.11.1.1.4.37.59.48\connections.xml

Answer 2

Assuming you have lost these while upgrading versions like I did, follow these steps to restore:

1. Open SQL Developer
2. Right click on Connections
3. Chose Import Connections...
4. Click Browse (should open to your SQL Developer directory)
5. Drill down to "systemx.x.xx.xx" (replace x's with your previous version of SQL Developer)
6. Find and drill into a folder that has ".db.connection." in it (for me, it was in o.jdeveloper.db.connection.11.1.1.4.37.59.48)
7. select connections.xml and click open

You should then see the list of connections that will be imported

Answer 3

If you don't find the connections.xml then right-click on Connections in the Connections view of SQLDeveloper, and choose Export connections.

Answer 4

It is stored in a file called connections.xml under

\Users\[User]\AppData\Roaming\SQL Developer\System\

When I renamed the file, all my connection info went away. I renamed it back, and it all came back. When I viewed the XML file, I found both test connection aliases, ports, usernames, roles, authentication types, etc.

Answer 5

In some versions, it stores it under

<installed path>\system\oracle.jdeveloper.db.connection.11.1.1.0.11.42.44
\IDEConnections.xml

Answer 6

For OS X my connection.xml files are in

/Users/<username>/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection.<oracle_version?>/

Answer 7

SqlDeveloper stores all the connections in a file named

connections.xml

In windows XP you can find the file in location

C:\Documents and Settings\<username>\Application Data\SQL Developer\systemX.X.X.X.X\o.jdeveloper.db.connection.X.X.X.X.X.X.X\connections.xml

In Windows 7 you will find it in location

C:\Users\<username>\AppData\Roaming\SQL Developer\systemX.X.X.X.X\o.jdeveloper.db.connection.X.X.X.X.X.X.X\connections.xml

Answer 8

I found mine in

C:\Users\<user>\AppData\Roaming\SQL Developer\system2.1.1.64.45\o.jdeveloper.db.connection.11.1.1.2.36.55.30\connections.xml

Answer 9

If you have previously installed SQL Developer then it will store the connection details in the 'connection.xml' which will be located in below mentioned path.

C:\Users\Username\AppData\Roaming\SQL Developer\system3.1.07.42\o.jdeveloper.db.connection.11.1.1.4.37.59.48

Once you get that 'connection.xml' try to import it into SQLDeveloper by right clicking to CONNECTIONS.

Answer 10

With SQLDeveloper v19.1.0 on Windows, I found this as a JSON file in

C:\Users\<username>\AppData\Roaming\SQL Developer\system<versionNumber>\o.jdeveloper.db.connection

The file name is connections.json

Answer 11

In a simpler way open search window and search for connection.xml gives a right click on that file and select open file/folder location. Once you get that connection.xml try to import it into SQLDeveloper by right clicking to CONNECTIONS.
