Where to find information about fixes

Stay informed about fixes: which ones are available to you, what particular fixes can do in your environment, and which fixes may not be necessary for you. Use this information to find out where you can get the latest updates about fixes.

As a system administrator, one of your responsibilities is to maintain your IBM^® i5/OS™ server. Part of that task involves knowing where to find information about fixes. You need to find out if there are any special instructions that relate to installing your fixes. You can avoid problems if you follow a fix maintenance strategy.

• Fix summary lists
  IBM service sends you only the fix that you ordered. If that fix is superseded by another fix, you need to know which superseded fix to order. Use the Fix summary list to make that identification.
• Fix cross-reference summary lists
  Use this summary list to make sure you order any fixes for the new release that you had at the previous release.
• Preventive service planning information
  Preventive service planning (PSP) information contains the latest information that is applicable to your hardware or software. PSP information should be reviewed before you install a licensed program, a cumulative PTF package, or hardware.
• Authorized program analysis reports
  Authorized program analysis reports (APARs) are used to find out what problems have been identified that could result in potential problems. You can view APARs by component, by release, or see the full list.
