For example, to specify a maximum rate of one message per 50 seconds, issue the
following command:
SYSPARMS EMSMAXRATE=0.02
To specify a maximum rate of 10 messages per second, issue the following command:
SYSPARMS EMSMAXRATE=10
Processing Event
Messages
After the messages reach NonStop NET/MASTER MS, the messages are processed as
shown in Figure 8-2.
The processing illustrated in Figure 8-2 follows this course:
1. Messages enter NonStop NET/MASTER MS from EMS and, if configured for
remote operations, from remote management applications over ISR. (The
EMSBKGCOLOR, EMSCOLOR, EMSHLITE, EMSLINELEN, EMSLINENUM, and
EMSNRD operands of the SYSPARMS command specify how NonStop
NET/MASTER MS processes EMS messages.) Messages are automatically sent to
the following destinations unless an EMSPROC procedure, which may or may not
be present, suppresses the messages:
The NonStop NET/MASTER MS activity log
The windows of authorized OCS users
The EMSPROC procedure can send messages to NCL procedures that you write.
The procedures can perform a number of operations, such as those discussed
under “Using an EMSPROC Procedure,” later in this section. The EMSPROC
procedure can also route messages to remote systems over an INMC link by using
the ISR. See Section 8, “Supporting Remote Operations,” for a discussion of the
procedures used to control ISR message flows. Using the NCL EMSCONT verb,
the EMSPROC procedure can send the message to either another NonStop
NET/MASTER MS system or forward it for default processing. Alternatively, you
can use the NCL EMSDEL verb to suppress the message. For a detailed discussion
of the NCL verbs and instructions for writing an EMSPROC procedure, refer to the
NonStop NET/MASTER NCL Programmer’s Guide.
2. Messages destined for the activity log are intercepted and processed by the
LOGPROC NCL procedure, if the procedure is present. If the LOGPROC
procedure is not present, all messages proceed directly to the activity log. See
Section 10, “Managing Activity Logs,” for additional information about the
LOGPROC procedure.
Messages destined for the OCS windows of users are intercepted and processed by
the MSGPROC NCL procedure that is active in the user’s OCS operator profile. If
there is no MSGPROC procedure active, all messages destined for the user’s OCS
window proceed directly to the window. See Section 4, “Managing User Access
and Privileges,” for additional information about processing messages sent to the
OCS window.
NCL procedures that receive messages process the messages.
