and commodity components
available for this purpose
cannot integrate as tightly as
the purpose-built end-to-end
infrastructure honed for decades
on the IBM mainframe
The mainframe's impact on
software development has been
similarly significant. IBM made
an early concerted effort to
support Linux on the mainframe
and other environments,
realizing that the then-nascent
open-software movement had
potential to augment z/OS
depending on workload types.
The OS is now widespread across
numerous technology platforms.
"That decision was a strategic
imperative within IBM, realizing
that open software is actually
a good thing. This is very
different from what a lot of our
competitors thought, believing
it to be an anathema. In fact, to
encourage open software, IBM
donated a tremendous number
of our patents to the open-source
community to provide them with
air cover," Meyerson recalls.
Some will say, "Well, of
course. The mainframe's been
around for 50 years, and that's
why it's leading in so many
areas." Though there's some
truth to this statement, the
people behind the mainframe
have pushed ahead while others
stood on the sidelines.
As Frey notes, "I wouldn't
characterize some of this as
incremental improvements to the
platform. Much of it was, in fact,
fundamentally transformational.
Take the Java* language, for
example. In the last generations
of the machine, we introduced a
hundred new CPU instructions
within the CPU architecture, of
which about 70 percent were
targeted specifically to further
improve the multithreaded
scalability and performance of
Java. And, really, that's just one

example of how committed we are
to pushing the envelope on the
mainframe. If some of that trickles
down to other platforms, either
within IBM or outside IBM, well,
that's just fine with us."

Jim Utsler is senior writer for IBM
Systems Magazine and has been
covering technology for more than
20 years.

WEBINAR

Did Ops communicate the problem?
Did Dev fix it yet?
Get smarter tools for smoother handoffs
WHO SHOULD ATTEND
Development Management, Operations Management, Application
Developers, Operations Specialists

WHEN
When: Thursday, January 23 | 8 PT / 10 CT / 11 ET

AGENDA
Smooth handoffs. They're essential in relay races and football - and
IT. After the root cause of a problem is isolated, how does Operations
or QA hand it off to Development? Typically, Development is manually
contacted without the key information needed to recreate and resolve
the problem. That's like running the race after dropping the baton.
These poor handoffs lead to extended MTTR, application backlogs, and
increased costs.
Now Compuware unites APM for Mainframe and Developer
Productivity solutions to make handoffs smoother than ever before.
New levels of integration between the tools used to find (monitor,
analyze, pinpoint) problems and the tools used to fix (recreate, debug,
test) problems jump start the resolution process.
Join us for a Webcast where you'll see this industry-first functionality
in action. Our experts will take you through a live demo and show you
how smarter tools help IT improve collaboration, quality and time to
market.
