WebSphere provides built-in commands for the usage of the embedded Derby database.
mqsicreatedb can be used to create database.
The first time a Derby database is created, a Windows service called IBM® MQSeries® Broker DatabaseInstanceMgr6 is created and started. This service is required in order to access Derby databases. This service can be started or stopped by the mqsistart and mqsistop commands, and automatically starts when Windows is started, if necessary. The service is deleted when the last Derby database is deleted. At most one Database Instance manager Windows service exists, even if you install WebSphere® Message Broker more than once on your Windows computer (multiple installed instances).
The database commands affect all the databases created in any installed instance on your Windows computer, regardless of the instance under which they are created. For example, the mqsilist DatabaseInstanceMgr6 command lists all the databases that have been created using the mqsicreatedb command on this Windows computer. Use the mqsichangedbimgr command to change the user name and password under which the Database Instance manager Windows service is run. Run this command only if passwords change or if user names are updated after the initial installation and configuration. For more information, see Using Derby databases on Windows.
