Therefore, to improve both the efficiency of the EM function and eliminate process
resource waste, advanced mode is preferred over extended basic mode. In advanced
mode, the NC process is not used, and the EM function is handled exclusively by an
EM process. In advanced mode, you may be able to significantly improve the
processing of EMS events if you configure the EM process with a high priority in a
relatively unused CPU, and if you spread the BK, IS, and MS processes across other
CPUs.
Changing Back From
Advanced Mode to
Extended Basic Mode
You should consider changing back from advanced mode to extended basic mode if
one or more conditions described in “When You Should Use Extended Basic Mode,”
above, apply again. In particular, if your workload decreases or you lose resources,
extended basic mode may be more appropriate for your workload.
Note If you intend to run NonStop NET/MASTER MS in extended basic mode, you must configure at least one
NC process.
Advanced Mode In a NonStop NET/MASTER MS system running in advanced mode, no NC processes
are present and at least one static or dynamic occurrence of each other process class
(BK, EM, IS, and MS) is present. Advanced mode divides application process
functions into BK, EM, IS, and MS processes, which collectively replace the NC
process.
Figure 11-4 shows the NonStop NET/MASTER MS programs and processes used in
advanced mode. This figure shows that four program files are required in advanced
mode: NCP, NGM, SECEXIT, and NMxxssdd. The figure shows that the BK, EM, IS,
and MS processes are created from the same program file (NMxxssdd).
