What is SMP/E?
System Modification Program Extended. An element of z/OS
that is used to install most software products. Applies the relevant parts of
Change Management to the installation and maintenance of software delivered in
executable (OCO) format, with no source code. Most notably, the ability to test
a new version of software (or maintenance to an old one) on a production system
while the old version is simultaneously being used by production
applications.
14 September 2001 - IBM SMP/E for z/OS and OS/390 V3R1 now
available stand-alone
SMP/E Environment
First, a few basic definitions:
- Global Zone
- Contains entries needed to identify and describe each
target and distribution zone to SMP/E. Information about SMP/E processing
options Status information for all SYSMODs SMP/E has begun to process.
Exception data for SYSMODs requiring special handling or that are in error
- Target Zone
- contain all the executable code needed to run the system.
- Dlib Zone
- contain all the elements, such as modules and macros,
that are used as input for running your system. One very important use of the
distribution libraries is for backup. Should a serious error occur with an
element on the production system, the element can be replaced by a stable level
found in the distribution libraries.
z/OS Maintenance Philosophy
There seem to be many schools of thought about how to setup
the data center's SMP/E environment.
1) To place all products under one Global Zone, with a
target and Dlib zone for each product.
2) To place all products in their own global, target and
Dlib zones.
3) To have a separate Global Zone for each software
vendor.
