Many parameters are dynamic meaning that changes take effect immediately; however,
changes to some parameters may require stopping and starting the instance. From the
Command Line, this can be done using the db2stop and db2start commands.
Before an instance can be stopped, all applications must disconnect. If you wish to
forcefully stop the instance, you can use the db2stop force command.
An instance can also be stopped through the Control Center by clicking on the instance
object and selecting either Stop or Start.
