Kernel Variant -f | -fast 

-f | –fast

Default value of the Database Manager CLI

Fastest database kernel variant, with minimum logging and runtime checks.

The specification of this option has the following effect:

Windows NT

During database instance registration, the service entry of the fast variant of the database kernel is used. The kernel variant fast is started when the command to start the database instance is run.

UNIX

The command to register the database instance has no effect. The specification of the option -f | –fast therefore only makes sense when starting the database instance.
