Overview of tasks to distribute software using central site distribution

The general tasks of distributing software from a central system include preparing the central system and target systems, creating the media, and installing the software on target systems.

1. Prepare to distribute software from a central system.
   1. Select the type of distribution media to use, an installation profile, and an installation method for the target systems.
   2. (Optional) write a user-defined installation program to eliminate installation tasks for the operators at the target systems.
   3. Ensure that you have the proper cumulative fix package or other PTFs applied on the central system.
   4. Ensure that the central system and target systems are ready for distribution
2. Create the distribution media using option 40 on the GO LICPGM menu.
   1. The following is a list of tasks completed using option 40:
      1. End all subsystems.
      2. Save the Licensed Internal Code, i5/OS operating system, system configuration data, security objects, system resources manager (SRM) objects, and user profiles.
      3. Save the QGPL library. This library includes the user-defined installation program called QLPUSER.
      4. Save the QUSRSYS library.
      5. Save licensed programs you want to distribute. Select licensed programs you want to distribute from the Save Licensed Program display. The Extended Base Support and the Extended Base Directory Support options are preselected because they are required.
   2. Save additional objects to the distribution media after option 40 is complete. For example, you can save user libraries, user directories, and secondary language files. If you write a user-defined installation program it can be used to restore these additional libraries and objects.
3. Install the distribution media on the target systems.

Do not put objects into the QGPL and QUSRSYS libraries on the central system that you do not want to distribute to the target systems.
