# Suspend JDBC data sources

In the Administration Console, you can manually suspend individual instances of a data source. When you suspend a data source, applications can no longer get a database connection from the data source. For connections that are already reserved by an application, behavior depends on the type of suspension that you select:

- Suspend - which marks the data source as disabled and blocks any new connection requests. An application will get an exception if it requests a connection or tries to use a connection it reserved before the connection pool was suspended.
- Force Suspend - which marks the data source as disabled, blocks any new requests for a connection from the connection pool, and closes and recreates connections currently in use.

Most connections in a suspended data source remain intact. The connections are not recreated when you resume the data source, except for the connections in use when the data source is Force Suspended.

To suspend a JDBC data source:

1. Navigate to the data source that you want to suspend:
   - Navigate to JDBC data source system resources
   - Navigate to JDBC application modules
2. Select the Control tab.
3. On the Control page, select the instances of the data source that you want to suspend.

   Date source instances are listed by the server on which they are deployed.

4. Click the Suspend button and select Suspend or Force Suspend.
5. Click Yes to confirm the action.

   Results are displayed at the top of the page, and the state of the selected data source instances is changed to SUSPENDED.
