#### Connection

The Catalog Doctor can be used to diagnose connections in the following aspects:

- Finding information of the current connection
  Select a connection from the resource tree. The connection information will be displayed in the left panel.
- Modifying the current connection
  Right-click the connection in the resource tree, and then click Modify on the shortcut menu. The Get JDBC Connection Information dialog will appear. You can now modify the connection.

  For a JDBC-ODBC bridge, you should give the ODBC data source name, and the user ID and password (if necessary).

  For a JDBC driver, uncheck Use ODBC Data Source, and check JDBC Driver. Fill in the class name of the driver, the URL, user ID and password (if necessary).

  You can also change the properties values in the Properties panel directly. Select a property value, and then choose or type in the value.
