Task 1. Determine Your Subsystem ID and Acronym
Task 1. Determine Your Subsystem ID and
Acronym
1. Register your company name with HP.
The company name is the Z-OWNER field (8-character) of your SSID.
2. Request a subsystem number and name from your subsystem number keeper.
The subsystem number is the Z-NUMBER field (16-bit signed integer) of your
SSID.
The number and name are assigned by the company that owns the subsystem and
must be unique among all the subsystems owned by that company. The company
should have someone designated as the keeper and assigner of all subsystem
numbers and names.
3. Request a subsystem acronym from your subsystem acronym keeper.
The subsystem acronym is a four-character ID assigned to your subsystem. You
will use the acronym as a prefix for the names of all your tokens and as a prefix for
the names of all your event definition files that you create.
NonStop Kernel subsystem acronyms are, by convention, the letter “Z” followed by
a three-letter subsystem abbreviation. For example, the HP Clock subsystem
acronym is ZCLK. To ensure your subsystem acronym is unique, start your
acronym with a letter other than “Z.”
The acronym is assigned by the company that owns the subsystem and must be
unique among all subsystems owned by that company. The company should have
someone designated as the keeper and assigner of all subsystem acronyms.
Task 2. Analyze Your Subsystem Environment
Manageability is the focus on easing the burden of running a system, Like quality
assurance, it must be an integral part of your subsystem design, not an afterthought.
When you design or add functions to a subsystem, consider how to:

Configure, control, or inquire about the functions in your subsystem

Quickly recover from failures

Anticipate problems (such as performance degradation) to prevent potential loss of
subsystem service
Quick recovery from failures means minimizing the amount of time your subsystem or
application is unavailable, and is necessary for providing a continuous availability
environment where a 7 x 24 business function can be implemented on NonStop
systems.
