z/OS provides systems management functions and fea-
tures to manage not only host resources, but also distrib-
uted systems resources. These capabilities have a long,
successful history of usage by S/390 customers. z/OS has
enhanced many of these systems management functions
and features to provide more robust control and automa-
tion of the basic processes of z/OS.
Console Enhancements
z/OS 1.5 includes consoles enhancements which are
designed to improve system availability by enhancing
the capacity and reliability of message delivery. Major
changes to the message production and consumption
fl ow can help reduce the possibility of bottlenecks which
can cause a backlog of undelivered messages. These
enhancements are available with z/OS 1.4 as an optional
no-charge Console Enhancements Feature. msys for Setup
has been enhanced in z/OS 1.4 to allow multiple users
to log on and work concurrently from different worksta-
tions. Furthermore, as part of the user enrollment process,
the msys for Setup user administrator can control which
msys for Setup workplace functions a user can access.
The graphical user interface (msys for Setup workplace)
has been redesigned and is now easier to learn and use.
These valuable ease-of-use enhancements make working
with msys for Setup more intuitive.
z/OS msys for Operations is a base element in z/OS 1.2
that incorporates automation technology into z/OS. It pro-
vides self-healing attributes for some critical system and
sysplex resources and can simplify the day-to-day opera-
tion of a single z/OS image or of a Parallel Sysplex cluster.
msys for Operations enhancements in z/OS 1.3 include
automation to handle enqueue contention and auxiliary
storage shortages. msys for Operations can also interface
with the Hardware Management Console (HMC) to provide
hardware functions such as deactivating LPARs.
RMF
RMF is IBM’s strategic product for z/OS performance mea-
surement and management. It is the base product to col-
lect performance data for z/OS and sysplex environments
to monitor systems’ performance behavior and allows
customers to optimally tune and confi gure their system
according to business needs. RMF provides its benefi ts
through the operation of Postprocessing and Online Moni-
toring functions. They are based on a set of data gatherers
and data services which enable access to all performance
relevant data in a z/OS environment. The four components
are RMF Data Gatherer, RMF Sysplex Data Services, His-
torical Data Reporting and Online Monitoring with RMF.
Enhancements
• RMF can show the contention for Cryptographic Copro-
cessors, including a description of which workloads are
using or are delayed in access to the cryptographic
coprocessors
• Application State Recording, a new feature of z/OS 1.4
provides more granular performance reporting for mid-
dleware such as WebSphere
• In z/OS 1.5, RMF Monitor II and Monitor III performance
data is now RACF protected
