3. Create a CONFIG file that includes or omits an application process definition for
each application process, as appropriate.
4. Start NonStop NET/MASTER MS.
The changes take effect after the NonStop NET/MASTER MS startup phase has
finished. See Section 2, “Starting NonStop NET/MASTER MS,” for startup
instructions.
When You Should Use Advanced Mode
Use the following guidelines to determine when you should use advanced mode:
You have a larger computer installation, such as an installation used in an
operations control center with many interactive user logons and many INMC
links. You need substantial resources (virtual memory, physical memory, process
resources, and so on) to satisfactorily run NonStop NET/MASTER MS.
You have the resources (virtual memory, physical memory, and process resources)
to run NonStop NET/MASTER MS in advanced mode. Advanced mode requires
more virtual memory, physical memory, process resources, and so on than basic
mode and (usually) more than extended basic mode.
You do not need to be able to start NonStop NET/MASTER MS quickly after an
installation or upgrade. Minimizing NonStop NET/MASTER MS startup time is
less important than configuring NonStop NET/MASTER MS, and you want to
configure NonStop NET/MASTER MS in advanced mode.
You do not want to run NonStop NET/MASTER MS using its default startup
configuration. You want to use a CONFIG file when you start NonStop
NET/MASTER MS, and you want to configure NonStop NET/MASTER MS in
advanced mode.
You do not need to make NonStop NET/MASTER MS available to users quickly.
For example, determining the optimal configuration of NonStop NET/MASTER
MS is more important to making NonStop NET/MASTER MS available to users,
and the optimal configuration is advanced mode.
Your system has a high workload. You need many processes to support the
workload. To better balance the workload, you want to spread the processes
across multiple CPUs. See “Supporting Multiple INMC Links” and “Managing
Interactive User Logon Processing,” later in this section, for more information.
You want to enhance the persistency of the functions performed by each process
class. You want to create additional application processes, spreading the
processes across multiple CPUs, to enhance persistency in case of process failure.
See “Configuring Application Process Persistency,” later in this section, for more
information.
You want to improve the efficiency of the EM function and eliminate process
resource wastage, as discussed earlier in this section in “Changing From Extended
Basic Mode to Advanced Mode.”
