Managing connection sessions
In the Services tool window, you can view data sources (1), connection sessions (2), and session clients (3).
When you connect to a database server from the IDE, IntelliJ IDEA and the server establish a session to exchange information. The session is a wrapper that stores information about the connection (connected or disconnected), transaction control (automatic or manual), the DBMS_OUTPUT state for Oracle (enabled or disabled), and other settings.
A session has two states: connected and disconnected. When you run a query to a database or refresh an object state, the session connects. A small green circle indicates that communication between the IDE and a data source is active.
If you close IntelliJ IDEA and open it again, all your sessions will be available in the Services tool window, but they will be disconnected.
A session node may include a different number of session clients. A session client is any entity that needs to communicate with a database. It can be a query console; an SQL file; a table, a view or any other object opened in the data editor.
The following table includes basic actions that you can use to work with sessions.
Action | Description |

Attach to an existing connection session | Click the <session> list and select an existing session.  |
