The central site distribution process allows you
to apply fixes to the central system and distribute them to the target system.
You apply fixes only once.
You can distribute fixes as part of the software involved in a full-system upgrade or logical partition. In the central site distribution process, fixes are distributed as follows. First, fixes are applied to the central system. When the distribution media is created, fixes are saved to the distribution media and distributed. Finally, when the distribution media is installed at the target systems, the Licensed Internal Code Copy A and Copy B is replaced and licensed programs are installed at the central system PTF level.
Using central site distribution to distribute fixes has
advantages. One advantage is that no special PTF installation instructions
are needed at the target systems. Another advantage is that the target systems
will be at the same PTF and release levels as the central system.
