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

implementation of enterprise wide unique identifiers for a variety of
parameters.

-
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.

JFS Log Logical Volume Name Standards
The following is a description of the standards for assigning AIX JFS
Log Logical Volume (JFS Log LV) names. A single standard has been
developed for use in standalone, High Availability, and Disaster
Recovery environments. This JFS Log LV naming standard provides the
mechanism to assign enterprise wide unique names to all AIX JFS Log LV'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.
To assign enterprise wide unique JFS Log LV names, the system
administrator must first define the resource
groups names. Once the resource group names have been defined, then
a Volume Group (VG) must be defined based on the RG name. After the VG
has been created, JFS Log LV's can be assigned. A VG will typically
contain one JFS Log LV's, however multiple JFS Log LV's can exist.
To define a JFS Log LV name, obtain the 8
character resource group name, then add the 4 digit logical volume
sequence identifier that will uniquely identify the JFS Log LV, followed
by the characters "lv". The 4 digit JFS Log LV sequence identifier will
consist of the characters "jfs" followed by a single digit to uniquely
identify the JFS Log LV. The JFS Log LV name will always end with the
characters "lv".
The JFS Log LV name shall consist of exactly 14 characters
with the following structure:
ApplicationCode + Environment + Function + Company + Sequence ID + "jfs" + JFS Log Sequence ID + "lv"
3 char + 1 char + 1 char + 2 char + 1 char + 3 char + 1 char + 2 char
As an example, a resource group named "egaapmx0", may have a volume
group named "egaapmx00vg". This volume group may have multiple JFS Log LV's
associated with it:
RG Name
Component
|
JFS Log LV
Sequence ID
|
JFS Log
LV ID
|
JFS Log
LV Name
|
|
egaapmx0
|
jfs0
|
lv
|
egaapmx0jfs0lv
|
|
egaapmx0
|
jfs1
|
lv
|
egaapmx0jfs1lv
|
|
egaapmx0
|
jfs2
|
lv
|
egaapmx0jfs2lv
|
JFS filesystems will require a logical volume for the JFS log. This
must also have an enterprise wide unique name.
