The extenders use services in the server as part of their operation. If these services are not already available as a function of normal "start-up" operations for the server, the system administrator starts them.
What the system administrator does: The system administrator logs on to the AIX server as the extender instance owner. The system administrator then issues the following command on the server:
DMBSTART
What happens: Extender services are started for the extender instance on the server. The DMBSTART command also starts a DB2 instance if it is not already running.
