This article was published in the April 2005 issue of
AIX Update magazine
and discusses system administration needs and requirements oriented
around users and groups. The overall emphasis of this series of
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.

- 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.

The following procedure is specific to an LPAR named "daladcal01" but
is representative of how to configure etherchannels on all virtual
LPAR's utilizing network adapters being provided from dual VIO
servers.
