  • 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.

  • This document references the standards implemented by Mt Xia to ensure business continuity for all business functions implemented on the AIX Power 5 architecture. Many of these standards are not specific to the Power5 architecture but are intended as enterprise wide standards for all AIX systems.

    These standards have been developed over many years of supporting standalone, high availability, and disaster recovery environments. The purpose of these standards is to ensure business continuity during normal system maintenance, planned and unplanned outages, hardware and software failures, network and communication failures, and/or a disaster recovery implementation.

    A design aspect of these standards is they can be implemented in a standalone, high availability, or disaster recovery scenario. Recognize that there are not multiple standards, one for each scenario, there is one single standard that is portable across all scenario's. This reduces support and training costs, and increases efficiency, supportability, recoverability, and availability.

    Some of the basic concepts of these standards:

    • Business functions are not tied to a specific machine.
    • Hardware resources can be shared or distributed among associated business functions.
    • Any system can act as a failover for any other system.
    • Any data center can act as a disaster recovery site for any other data center.
