Automated
Performance of
Operations Tasks
Operators and programmers can use NCL to automate the performance of routine
operations tasks. Using built-in functions and event message processing verbs, an
NCL procedure can automatically initiate actions based on:
Receipt of specified event messages and classes of event messages
The date and time of day
Event thresholds
An NCL procedure can interpret Subsystem Programmatic Interface (SPI) tokens and
analyze their contents. Therefore, an NCL procedure can distinguish among different
kinds of EMS messages, such as critical event messages and action event messages.
For example, an NCL procedure that receives an EMS message can determine whether
the message contains a ZEMS-TKN-EMPHASIS token and, after analyzing the
contents of the critical message, initiate some action. Some possible actions include:
Reformat the message, add information to the message, or automatically invoke an
online help facility so that an operator can understand the message more easily.
Route the message to specific users.
Take a recovery action, based on events occurring within a time period that you
specify.
Forward a notification message to a remote node if, for example, automated
recovery attempts on the local node fail.
Start multiple automation subtasks.
NCL can also interpret NMVT and unformatted text messages.
Among other operations, RMS lets you define rules to automate tasks that control the
operation of your system and network. Refer to the NonStop NET/MASTER RMS
Management and Operations Guide for more information.
A comprehensive discussion of NCL processing of EMS messages and other SPI
tokens appears in the NonStop NET/MASTER NCL Programmer’s Guide.
