AIX Software Packaging

• Software packages usually have 4 version numbers, e.g. 4.2.1.0 is version 4 release 2 modification 1 fix level 0.
• First 3 numbers indicate a unique fileset. Last number indicates a fix to that fileset.
• Installation is done via installp, but I recommend you use SMIT for this.
• Useful SMIT functions:
  • Update All (install latest fixes of all installed packages)
  • Install/Update from ALL Available Software
• Can use lslpp -L to list all available software.
• "Commit" concept - if committed, an update can't be uninstalled.
