Note The EMS message NNM0553, described earlier in this section, is displayed if you exceed recommended
capacity limitations (more than 10 interactive user logons or more than one INMC link in the NC process).
Changing Back From
Extended Basic Mode to
Basic Mode
You should consider changing back from extended basic mode to basic mode if one or
more conditions described in “When You Should Use Basic Mode,” above, apply
again. In particular, if your workload decreases or you lose resources, basic mode may
be more appropriate for your workload.
Note If you intend to run NonStop NET/MASTER MS in basic mode without a CONFIG file, you must name the
application process program file either NMNC0100 or NMNC0001.
Extended Basic Mode In a NonStop NET/MASTER MS system running in extended basic mode, at least one
static or dynamic NC process is present and a combination of other application
processes is present.
A typical configuration is one static NC process, one dynamic IS process, and one
dynamic MS process.
In this configuration, the NC process supports the EM function. Virtual users and
their workload are supported by the BK function of the NC process. The NC and IS
processes each support one INMC link. Interactive user logons (20 maximum) are
allocated to the NC and MS processes in a circular fashion. Each additional INMC link
is supported by an additional dynamic IS process. Each additional group of 10
interactive user logons is supported by an additional dynamic MS process.
Using this configuration, an appropriate process class is used to handle increased
workload, and process creation is highly visible, allowing you to easily determine the
reasons for increased workload.
Figure 11-3 shows the NonStop NET/MASTER MS programs and processes used in a
typical extended basic mode configuration. This figure shows that four program files
are required in extended basic mode: NCP, NGM, SECEXIT, and NMxxssdd. The
figure shows that the IS, MS, and NC processes are created from the same program file
(NMxxssdd).
