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.
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
Assuming you have lost these while upgrading versions like I did, follow these steps to restore:
Open SQL Developer Right click on Connections Chose Import Connections... Click Browse (should open to your SQL Developer directory) Drill down to "systemx.x.xx.xx" (replace x's with your previous version of SQL Developer) 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) select connections.xml and click open
You should then see the list of connections that will be imported
If you don't find the connections.xml
then right-click on Connections
in the Connections view of SQLDeveloper, and choose Export connections
.
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.
In some versions, it stores it under
<installed path>\system\oracle.jdeveloper.db.connection.11.1.1.0.11.42.44
\IDEConnections.xml
For OS X my connection.xml files are in
/Users/<username>/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection.<oracle_version?>/
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
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
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
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.
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.
for macOS
/Users/joseluisbz/.sqldeveloper/system18.1.0.095.1630/o.jdeveloper.db.connection/connections.xml
On linux systems:
~/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection/connections.xml
To recover your password, locate the product_preferences.xml file in the following location:
C:\Users[username]\AppData\Roaming\SQL Developer\system*\o.sqldeveloper\product-preferences.xml
Then, search for the string db.system.id and copy the value of the v attribute. That is your decryption key to use when you are prompted to enter your decryption key on the Password Handling panel during the import processing on SQL Developer.
