2.9 OS/390 Documentation Resources
OS/390 documentation resources should be consulted as early on in the project
as possible. This should be done in order to get an understanding of some of the
issues associated with installing and implementing the OS/390 environment. For
example, it will be necessary to understand the various OS/390 delivery
mechanisms (that is, CBIPO, ServerPAC, SystemPac) in order to determine the
one most appropriate based upon the given requirements/environment.
