3. Enter the following command to update the backup process CPU value and to
implement the change:
PROCESS ALTER=$ZNNM BACKUPCPU=3 DEFER=NO
When the command finishes, the NCP is running in CPU 2 (primary) and 3
(backup).
Balancing Static and
DSNM Processes
Among CPUs
As described earlier in this section in “PARAM Commands Used to Create a Process
Definition,” you can use the PROCESSCPU operand in the CONFIG file to specify the
first-preference and second-preference CPUs for creating a static or DSNM process.
After NonStop NET/MASTER MS startup, you can change the preferred CPUs by
using the PROCESS ALTER command with the CPU operand. The change takes effect
when the NCP next starts the static or DSNM process.
The following example changes the preferred CPUs for creating $A001 from their
current values to CPUs 2 and 3:
PROCESS ALTER=$A001 CPU=(2,3)
Influencing How
Dynamic Processes
Are Balanced Among
CPUs
So that you can partially automate how NonStop NET/MASTER MS balances the
workload of dynamic processes, NonStop NET/MASTER MS lets you influence how
dynamic processes are balanced among CPUs.
Two factors determine how dynamic processes are balanced among CPUs: the relative
availability of a CPU, or CPU weight, for the creation of dynamic processes; and the
CPU resource consumption, or process weight, by a dynamic process. This subsection
discusses the following topics:
Configuring CPU weight
Configuring process weight
How these two factors interact to let you determine how dynamic processes are
balanced among CPUs
Configuring CPU Weight CPU weight refers to the relative availability of a CPU for the creation of dynamic
processes. Relative availability is measured in conceptual units, from 0 (the CPU is
unavailable) through 100 (the CPU is completely available). You can specify a CPU
from 0 through the highest existing CPU number in your system (the highest possible
value is 15), and you can configure CPU weight during or after NonStop
NET/MASTER MS startup: the same command, PARAM CPUWEIGHT, is used in
both cases.
Use the SHOW CPUWEIGHT command to display information about CPU weight.
Refer to the NonStop NET/MASTER MS Command Reference Manual for more
information about the PARAM CPUWEIGHT and SHOW CPUWEIGHT commands.
