You can automatically connect to a database when AQT starts.
This is done by specifying the conn startup parameter. This is discussed in the section Startup Command Arguments.
The following is an example of a batch script to start AQT and connect to a database. The command used in this script can also be used in a desktop icon to start AQT with connect.
Notes:
You can also achieve this functionality by starting AQT with a particular session.
