<p>The Qbase configuration gives the ability to run all of the same functions
|
||
|
|
that you can run with the Qctl configuration and is easier to manage because
|
||
|
|
it consists of fewer subsystems.</p>
|
||
|
|
<p>The Qctl default configuration allows for more individualized control over
|
||
|
|
your system operations by dividing the system activity into different subsystems
|
||
|
|
based on the type of activity. For example, if you want to run batch jobs
|
||
|
|
over the weekend, but do not want anyone to be able to sign on (except at
|
||
|
|
the console), you can easily do that with the Qctl configuration by ending
|
||
|
|
the Qinter subsystem.</p>
|
||
|
|
<p>If you are considering creating your own subsystem configuration, you might
|
||
|
|
also find that it is easier to use the Qctl configuration as a starting point
|
||
|
|
than the Qbase configuration.</p>
