IBM AIX uses its own packaging format known as installp for installing, uninstalling, and managing software packages. You can use the installp command to install filesets from an installation package. All the software that are part of the AIX base image are packaged in the installp format.
This tutorial describes the process of creating your own AIX installp packages. Building installp packages on AIX is a straightforward task with the help of the /usr/sbin/mkinstallp command. mkinstallp belongs to the bos.adt.insttools fileset from the bos.adt package, which is available in the AIX Base media. It is important to note that root privileges are necessary to build a package.
