Installation profiles for central site distribution

IBM supplies four installation profiles that you can use to install the distribution media at the target systems. You can also customize these profiles to suit your specific needs.

Installation profiles contain the tasks you want to perform during the installation process. They bring many benefits to the automatic installation process. The choices you make when creating an installation profile affect only the target systems, not the central system. You can use one of the profiles supplied by IBM, or you can customize the profiles supplied by IBM to better suit your needs.

IBM installation profiles

IBM provides installation profiles that fit almost every situation. The following is a list of installation profiles in order of most commonly used. This list includes profile descriptions and special considerations associated with each.

Replace current release (QRPLRELLVL): Use this option to distribute the software involved in a full-system upgrade. The system replaces licensed programs that are at the same version, release, and modification as on the media.
Install new system (QINSNEWSYS): Use this option to distribute the software involved in a full-system upgrade to a new target system. That is, you can use central site distribution to install a new system. Or, you can use this option to distribute the software of a logical partition. The target systems must already have the current level of the licensed internal code installed.
IBM replace current release (QIBMRPLRLS): Use this option to distribute the software involved in a full-system upgrade. The system does not replace licensed programs that are at the same version, release, and modification as on the media.
Change primary language (QCHGPRILNG): If you plan to distribute the software involved in a full-system upgrade or the software of a logical partition and you want to change the primary language, use either the Replace current release profile or the IBM® replace current release profile. If you plan only to change the primary language on the target system, refer to Considerations for changing a primary language.
