articles is for implementation of enterprise wide unique identifiers
for a variety of parameters, such as user names, group names, UID and
GID numbers.

aliases. The overall emphasis of this series of articles is for
implementation of enterprise wide unique identifiers for a variety of
parameters.

logical volumes, directory mount points, etc. The overall emphasis of
this series of articles is for implementation of enterprise wide unique
identifiers for a variety of parameters.
- Successful Business Continuity - Part 4 - MQ Series, Startup/Shutdown Scripts, Error Processing
-
This article was published in the April 2006 issue of
AIX Update magazine
and discusses how to implement AIX in an environment dedicated to
business continuity. The topic of this article is the assignment of MQ
Series queue names and aliases, resource group startup and shutdown
script names (Application startup/shutdown script names), error logging,
and error notification.
- Successful Business Continuity - Part 5 - Miscellaneous topics
-
This article was published in the August 2006 issue of
AIX Update magazine
and discusses how to implement AIX in an environment dedicated to
business continuity. A variety of topics is discussed in this article
including automated documentation generation and management.
- Automated Microcode Management System
-
One of the most difficult administration tasks in an AIX environment is
attempting to keep the firmware and microcode up-to-date. Mt Xia has
devised an automated method of gathering the Microcode information,
determining which microcode needs to be updated, generating reports, and
uploading the required microcode updates to each individual system.
- Calculating the size of a Virtual Processor
-
This document describes the algorithms used to calculate the size of a
virtual processor when using shared processors in an LPAR. The IBM
documentation describes how to calculate CPU utilization, NOT how to
size for configuration, this document clarifies this process. A
description of the HMC input fields for the processor tab is included.
- Basics of Partition Load Manager Setup
-
This presentation was provided by Ron Barker from IBM regarding the PLM Basic
setup.

User Name Standards
This document describes the standards for assigning user names and
UID numbers in Mt Xia's AIX environment. A single standard has been
developed for use in standalone, High Availability, and Disaster
Recovery environments. This user naming standard provides the mechanism
to assign enterprise wide unique user names to all AIX users's and will
eliminate naming conflicts in the event of a manual or automated
failover, or if multiple instances of an application are running on a
single server.
Users are normally divided into two major categories on a Unix
system, administrators and normal users. Applications such as
databases, SAP, MQSeries, etc normally require an administration user
name and possibly a group name. With each new user created on a Unix
system a user ID number is assigned to that user, this user ID number is
referred to as the UID number and is normally unique to that user on
that one Unix system. When building highly available and/or recoverable
systems, the user name and UID number must be enterprise wide unique
values. Therefore a centralized user management system must be
implemented to manage users and UID numbers to ensure that no two users
have the same user name or UID number.
This centralized user management function is performed in Mt Xia's
environment by LDAP. All user requests and assignments must be
performed through the centralized user management system via the LDAP
servers.
