When You Should Use Extended Basic Mode
Use the following guidelines to determine when you should use extended basic mode:
You have a medium-size computer installation with more than 10 interactive user
logons or more than one INMC link. You need more than minimum 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,
and so on) to run NonStop NET/MASTER MS in extended basic mode. Extended
basic mode requires more virtual memory, physical memory, process resources,
and so on than basic mode and (usually) less than advanced 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 extended basic 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
extended basic 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 extended basic mode.
NonStop NET/MASTER MS has a moderate and variable workload. You need to
use additional application processes from time to time to supplement the
workload performed by the NC process. To better balance the workload, you may
also want to spread 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 the NC
process. You want to create additional application processes, perhaps spreading
the processes across multiple CPUs, to enhance persistency in case of process
failure. See “Configuring Static and Dynamic Application Processes,” earlier in
this section, for more information.
You notice that the NCP creates an additional NC process to support unexpected
workload, as discussed earlier in this section in “Changing From Basic Mode to
Extended Basic Mode.”
Changing From Extended
Basic Mode to Advanced
Mode
You should consider changing from extended basic mode to advanced mode if one or
more conditions described in “When You Should Use Extended Basic Mode,” no
longer apply. In particular, if your workload increases or you gain additional
resources, performance and application process persistency is likely to improve in
advanced mode.
