Checking prerequisites

Before you install each product, run the IBM® Prerequisite Scanner (PRS) to ensure that the target host is suitable, and no installation problems are foreseeable. Also check the maxproc and ulimit settings on the servers you are configuring to ensure they are set to the appropriate minimum values.

Before you begin

  • For information about hardware and software compatibility of each component, and detailed system requirements, see the IBM Software Product Compatibility Reports website: http://www-969.ibm.com/software/reports/compatibility/clarity/index.html external link
    Tip: When you create a report, search for Netcool® Operations Insight® and select your version (for example, version 1.6.8). In the report, more useful information is available through hover help and more links.
    For example, to check the compatibility with an operating system for each component, go to the Operating Systems tab, find the row for your operating system, and hover over the icon in the Components column. For more detailed information about restrictions, click the View link in the Details column.
  • Download IBM Prerequisite Scanner from IBM Fix Central at http://www.ibm.com/support/fixcentral/ . Search for IBM Prerequisite Scanner.
  • After you download the latest available version, decompress the .tar archive into the target directory on all hosts.
  • On the IBM Tivoli® Netcool/Impact host, set the environment variable IMPACT_PREREQ_BOTH=True so that the host is scanned for both the Impact Server and the GUI Server.
