SYSPARMS
Operand Valid Values Default Value
Process name EMSDISTPNM Local process name; remote
process names are not allowed.
If you omit this operand, NonStop NET/MASTER MS
creates a name that begins with the letter X, Y or Z.
Execution
priority
EMSDISTPRI An integer from 1 through 199. The same as the priority of the NonStop NET/MASTER MS
process that supports the interface to EMS and the
processing of EMS events (either an EM process or an NC
process). (By default, the priority of each process class is
one less than the execution priority of the NonStop
NET/MASTER MS control process (NCP). See Section 11,
“Configuring the Processing Environment,” for more
information about process priorities.)
Primary CPU EMSDISTPCP An integer from 0 through 15;
the value must differ from that of
the backup CPU.
1
Backup CPU EMSDISTBCP An integer from 0 through 15;
the value must differ from that of
the primary CPU.

Starting and Stopping the Consumer Distributor
Use the EMSDIST command to either start or stop the receipt of event messages from
the EMS consumer distributor process specified by the EMSDISTCOLL operand of the
SYSPARMS command. To begin receiving messages from the distributor, issue the
following command:
EMSDIST START
The events are forwarded to NonStop NET/MASTER MS for processing. See
“Processing Event Messages,” later in this section, for a description of event message
processing within NonStop NET/MASTER MS.
To stop the receipt of messages from the distributor, issue the following command:
EMSDIST STOP
Whenever you enable or disable the receipt of event messages, NonStop
NET/MASTER MS reports the change by sending a message to the activity log and to
all monitor-class terminals.
Global Message Filtering As a general rule, you minimize the consumption of system and network resources by
suppressing a message at the earliest opportunity, usually in the EMS consumer
distributor filter. Global message filtering enables you to suppress subsystem event
messages before the EMS consumer distributor forwards them to NonStop
NET/MASTER MS. A filter discards messages according to criteria that you specify.
If a message is not to be acted upon by either an operator or an NCL automation
procedure, discard the message with a filter.
