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.

Microcode Management
Systems without an HMC
Use IBM's
Microcode Discovery Service at the following URL to determine what
microcode should be updated, to retrieve the microcode, and the
instructions for installing the microcode.
https://techsupport.services.ibm.com/server/aix.invscoutMDS
Normally the "java applet" is used to peform the microcode discovery
which requires the password for the user "invscout" to be set. This
also requires internet communication from the system over port 808. To
use the java applet perform the following steps on the target
system:
- Set the password for the user "invscout"
passwd invscout
- Clear the password administration flags on the user "invscout"
pwdadm -c invscout
- Start the "invscout" daemon
invscoutd
- The system is now ready for microcode discovery via the java applet
- The microcode discovery service will require several pieces of
information to be able to perform the survey:
- Fully qualified hostname of the system
- Password for the user "invscout"
- Port number (default: 808)
- System Model Number
lsattr -El sys0 -a modelname -F value
- System Serial Number
lsattr -El sys0 -a systemid -F value
Systems with an HMC
Use the facilities built into the HMC for performing microcode updates
to all managed systems.
