What Is RMS?

Improve productivity as follows:
Routine tasks are performed automatically, reducing the number of tasks that
require human intervention.
Different messages are selectively passed to operators who perform different
functions, presenting operators with less nonessential messages, thus reducing
the operator response time.
RMS uses rules to determine the message filtering and task automation actions. There
are three types of rules:
Message action rules that react to messages
Message group rules that react to groups of messages
Time-based rules that react to time events
A collection of related rules is known as a ruleset. You create your rulesets and rules,
and RMS stores them in a user database (UDB) file. RMS contains the following main
components (Figure 1-1):
Message Handler—An RMS message handler is an executing NCL procedure.
You use the message handler to process messages and to perform tasks when
certain messages arrive. The handler uses a ruleset to determine how to process
the messages and what tasks to perform. You can define your own rulesets and
rules to satisfy your requirements. When you start a message handler, you specify
the ruleset that the handler is to use, and RMS loads the ruleset into memory.
You use different types of message handlers to handle the following types of
messages:
Messages from outside of NonStop NET/MASTER MS. You start the message
handler as an EMSPROC.
Messages to the NonStop NET/MASTER MS activity log. You start the
message handler as a LOGPROC.
Messages to a NonStop NET/MASTER MS Operator Control Services (OCS)
window. You start the message handler as a MSGPROC.
Messages to the dependent queues of the handler. You start the INT-type
message handler in your current environment or a background processing
environment.
Timer Driver—RMS starts the timer driver during startup. The timer driver loads
time-based rules and starts timers according to the rules to perform tasks at
specific times.
Panel Interface—The panel interface facilitates your interaction with RMS as
follows:
Control the operation of the message handlers and timers. You can monitor
and control the actions invoked by the message handlers. You can freeze a
subject such that when a message handler receives a message containing that
