PARMLIB(IGDSMSxx) as well
as in the ACS routines. This
allows storage administrators
to have one set of ACS routines
but change USER_ACSVAR
depending on the environment.
This enhancement potentially
results in fewer errors between
environments due to ACS
routine differences.

need to define z/OS Global
Mirror workload-based write
pacing on a per-volume level,
allowing greater flexibility in
configurations. Some of these
changes have also been retrofitted
into previous z/OS versions.

Enhanced Environments
We have come a long way with z/OS, and 2.2
offers great features and enhancements to manage
environments. Legacy systems will benefit, as will
integrating with the mobile and cloud environments
on a z/OS system. z/OS has a bright future to
continue to be a leader in technology.

Storage Updates
Many IBM disk customers use
Easy Tier* to manage data both
between tiers and laterally
within a tier. Executing a DB2
REORG in a tiered environment
caused problems. For example,
some of the data set resided on
an SSD, and some on an HDD;
after the REORG we begin the
learning curve again and start at
the HDD level. z/OS 2.2 allows
for DB2-related hints so this type
of scenario doesn't occur. DB2
10 for z/OS and higher can take
advantage of this enhancement,
which can be retrofitted to z/OS
2.1 with an APAR.
Several other storage-related
features are included in z/OS
2.2 for Peer-to-Peer Remote
Copy (PPRC)/Metro Mirror,
such as Multi-Target PPRC,
which allows a single volume
to be the source for more than
one PPRC relationship, and
IBM zHyperWrite*: DS8870
Log Write Accelerator for
DB2, a new technology that
combines DS8000* and z/OS
enhancements that deliver
performance benefits for
writing operations to DB2 logs
in the Metro Mirror (PPRC)
environment. This reduces
latency overhead, compared
with normal storage-based
synchronous mirroring.
With z/OS 2.2 and storage,
incremental FlashCopy supports
up to 12 targets, instead of
support of one for incremental
FlashCopy for any individual
volume. This prevents the
