Refer to the PARAM command in the NonStop NET/MASTER MS Command Reference
Manual, and see Appendix B, “Default Configuration Values Reference,” for the
default values of all startup parameters. Section 2, “Starting NonStop NET/MASTER
MS,” explains how to start NonStop NET/MASTER MS using its default startup
configuration.
Customized Startup Configuration
The setting of a startup parameter is changed using the PARAM command in a
CONFIG file. When a CONFIG file is used, NonStop NET/MASTER MS is started
using a customized startup configuration.
Tandem recommends that you use a CONFIG file to customize NonStop
NET/MASTER MS for prolonged testing and for use in production environments.
Section 3, “Configuring NonStop NET/MASTER MS,” and Section 11, “Configuring
the Processing Environment,” explain the procedures you follow to start NonStop
NET/MASTER MS with a customized startup configuration.
Dynamic Startup Reconfiguration
After NonStop NET/MASTER MS startup, you can use the PARAM, PROCESS
ALTER, and PROCESS SWITCH commands to dynamically reconfigure certain
startup parameters used to define NonStop NET/MASTER MS process attributes. For
example, you can:
Alter the weight currently allocated to a CPU, to control the use made of a CPU by
dynamic processes
Modify the CPU resources that a dynamic process can use
Redefine certain types of processes, currently running without a backup process,
to run as process pairs
Redefine certain types of processes, currently running with a backup process, to
run without a backup process
Change the backup CPU for a process currently running as a process pair
Switch the primary and backup processes of a process pair
Dynamic reconfiguration of startup parameters means that you do not have to shut
down and restart NonStop NET/MASTER MS to balance certain attributes of
processes in the processing environment. This capability increases the availability of
NonStop NET/MASTER MS.
Section 11, “Configuring the Processing Environment,” explains how to dynamically
reconfigure process attributes.
