Total System Package systems and preloaded systems are licensed to receive their own IBM distribution
media and fixes. Licensed program distribution need not be a part of central site system activity.
Distributing applications and system control information can be done through communications in a
distributed systems network or by
Release-Level interoperability
It is the responsibility of the central site to ensure that the central site and the target site have compatable
software releases. This is especially important if you want to have objects and data interchange between
systems.
Note: You can see the installed release of licensed programs by
using option 10 (Display licensed programs) on the Work
with Licensed Programs menu. This displays the release
of licensed programs that were initially shipped with an
operating system release or modification level. Use the
Display Software Resources (DSPSFWRSC) command to
see the release of licensed programs not initially shipped
with an operating system release or modification. You can
also use this command to see what Program Request for
Price Quotations (PRPQs) and licensed program offerings
(LPOs) are installed on the system.
Interoperability is the ability of one system to exchange data or objects with another system. The
exchange can be performed electronically or by physical media (such as tape). Either system may initiate
the exchange.
An iSeries server interoperates with another iSeries server when exchanging data or when saving and
restoring objects.
For more information on saving objects to a system running a previous release, see the chapter on
release-to-release support in Backup and Recovery
.
Exchanging data between different release levels
The source system (the system that sends the information) and the system that receives the information
must be within the supported release levels. If the source system is at the current release level, the
system receiving information can be at V3R2M0 or any level of Version 4 operating system.
Saving and restoring objects between different release levels
Objects that are interoperable must be saved by specifying either a specific release level or *PRV for the
value of the target release (TGTRLS) parameter.
For more information on saving objects to a system running a previous release, see Backup and Recovery
.
Licensed programs can be saved and restored similar to other objects as long as the release level is
compatible with the operating system release level. For more information about compatible levels of
licensed programs, refer to Licensed Program Information section in Software Installation
.
Fix (PTF) level of the central and target systems
IBM periodically makes fixes available to update licensed program code between releases. For information
on avaliable fixes, see Managing fixes with Management Central.
