  • 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.

  • 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.
