ADMINISTRATOR

A Step UP
Java with z14 features hardware facilities for secure, high-performance
transaction processing

S

kills, cost and portability of applications are key factors driving client decisions
about where, when and how to invest in application development. With this in
mind, Java* on IBM Z* has received a tremendous amount of focus, as its value
proposition has never been better.

Marcel Mitran
is a Distinguished
Engineer and CTO
for IBM LinuxONE.
Joran Siu
is a development
lead for the
IBM Software
Development Kit
for Node.js for
IBM Z.
Clark Goodrich
is a senior
software engineer
in the
IBM Systems,
IBM Z
performance
organization
working on the
Java compiler.

In a survey of 95 IBM Z clients
conducted in 2016, 85 percent
of them now have Java on Z in
production. Of these, more than
80 percent described their Java
on Z project as successful or very
successful. Clients continue to be
vocal about the advantages they
gained from Java on Z. This isn't
surprising given the significant
investment that has gone into
making Java a first-class language
on the platform. Java has been
deeply integrated across the
stack, including the addition of
new facilities in four generations
of IBM Z processors, IBM z
Integrated Information Processor,
offload engines, z/OS* system and
the broad portfolio of missioncritical middleware including
IBM Db2*, CICS* and IMS*.
The trend for the adoption
and integration of Java on Z
is consistent. An IDC study,
"The Business Value of the
Connected Mainframe for Digital
Transformation" (ibm.co/2pf8asQ),
emphasizes modernizing on the
mainframe means creating a
platform that's integration-ready
within the data center and with the
industry, a natural participant in
business innovation.

The study places Java at the
heart of modernization and
innovation of the mainframe.
What is it about Java that puts it
in such an esteemed position?
First, it continues to be a leading
language of choice in the IT
industry. Redmonk and other
language ranking frameworks
still consistently place Java at
the top of the list of languages of
choice for developers. With two
decades of know-how, the Java
language, its developers, tools and
ecosystem are mature and well
seasoned, making the language
well positioned to meet the needs
of the mission-critical enterprise.
Java sets the bar as a standardized,
safe and portable environment
that enables true fit-for-purpose
placement of workload.
Java on Z provides performance
at a very competitive price point.
With the IBM z14*, IBM has taken
Java to the next level with new
hardware facilities like pause-less
garbage collection (GC),
high-performance encryption
and decimal processing
acceleration-giving Java on Z
the ability to handle secure and
high-performance transaction
processing at-scale.

Leading Performance
Years of investment in co-design
of the IBM Java VM (JVM) and
IBM Z processor, OSs and
middleware have made Java on
IBM Z what it is today. With the
world's fastest processor, largest
caches and high-performance
simultaneous multithreading,
the processor provides an ideal
Java execution environment.
With over 200 new instructions
co-designed and exploited by
the IBM Software Development
Kit and significant investment
in performance and innovation,
Java on Z provides industryleading performance.
For example, workloads like
DayTrader-an end-to-end
Java Enterprise Edition web
application for benchmarking-
running on WebSphere*
Liberty deliver up to 1.6x
better throughput per core on
z14 than on x86 alternatives.
Similarly, Java on z14 running
IBM Operational Decision
Manager-a full featured
platform for capturing,
automating and governing
frequent, repeatable business
decisions-is up to 1.7x better
than on x86 alternatives.
