NET/MASTER RMS Management and Operations Guide

12 Base Rulesets
115415 NonStop NET/MASTER RMS Management and Operations Guide 12–1
This section describes the two base rulesets that RMS provides: BASERULE, which
automates error recovery tasks, and STATSCAP, which captures statistics on the
message flow in an environment.
BASERULE The BASERULE ruleset enables you to automate various system error recovery tasks.
The ruleset contains the following message action rules that act in response to event
messages:
Rule Function
ZCPUDOWN Dumps the memory of a failed central processing unit (CPU) and reloads
the CPU.
ZCPUUP Rebalances the CPUs after reloading a failed CPU.
ZDEVICEDOWN Restarts a failed asynchronous device.
ZSUBDEVDOWN1 or
ZSUBDEVDOWN2
Restarts a failed asynchronous subdevice.
ZEXPANDNOTRY Restarts a failed Expand line.
ZPATHTCPFAIL Restarts a failed Pathway terminal control process (TCP) and the
associated terminals.
ZPATHTRMABRT Restarts an aborted Pathway terminal.
ZPATHTRMSUS1 or
ZPATHTRMSUS2
Restarts a suspended Pathway terminal.
ZSNAXINOP or
ZSNAXNOTRDY
Restarts a failed SNAX/XF line.
ZTACLFAIL Restarts a TACL process that was stopped due to input-output errors.
Note The following rules can process local messages only (messages originating from the Tandem system on
which RMS resides): ZCPUDOWN, ZDEVICEDOWN, ZSUBDEVDOWN1, ZSUBDEVDOWN2, and
ZTACLFAIL.
The rules act in response to event messages that come from Tandem subsystems.
Refer to the Operator Messages Manual for an explanation of the operator messages.
To use the BASERULE ruleset, you must ensure that the following prerequisites are
satisfied:
You must have Distributed Systems Network Management (DSNM) on your
system, and NonStop NET/MASTER MS must be able to access it.
The environment serviced by the message handler using BASERULE must be able
to receive EMS messages.
