applications with HPE
Redefines its environment by implementing a
low-risk, high-return mainframe migration
The Tel Aviv Stock Exchange needed to
migrate its mission-critical applications from
an IBM mainframe environment and turned to
HPE Data Center Platform Consulting services
to help plan and implement a platform
migration strategy from its older, proprietary
systems. With HPE Data Center Platform
Consulting, the Tel-Aviv Stock Exchange was
also able to bring industry-leading availability,
increased performance, and uncompromising
client choice to support all of its IT needs.
The Tel Aviv Stock Exchange (TASE) is the
only stock exchange in Israel. It oers a “onestop shop” that includes trading in equities,
bonds, and derivatives. TASE has 25 members
including Israeli and international banks and
brokers, and TASE is trading in 1,900 equities
and bonds and 2,500 derivatives series.
Its daily turnover in the equities market is
approximately 1.5 billion Israeli shekels, which
is about $400 million

“It was very important for us to find one supplier that could provide a full
integration project, including the hardware, the operating system, and the
migration project itself. We approached HPE because we were familiar with
HPE’s capabilities and could get the benefits of HPE’s expertise at dierent
steps in the project.”

Migrating existing
infrastructure
The TASE Information Technology and
Operations Department develops and
operates all the organization’s businesscritical systems, including trading, clearing
and settlement, and risk management. The
goal of the department is to achieve nonstop trading and invest in remaining at the
forefront of technology. The importance that
TASE places on IT is evident in the size of the
department, which comprises some 60% of
exchange employees.
“About two years ago we started looking at
migrating our IBM mainframe applications
to another environment,” says Eldad Herstig,
Senior Vice President, CIO, & Head of
Operations for the Tel Aviv Stock Exchange.
“Our main reason to implement our migration
project was to reduce the risk related to
continuing working with the mainframe in
dierent areas. As a non-stop operation,
it’s very hard to migrate critical systems
while managing the risks of avoiding system
failures. In order to do so, you have to have
the right partner to ensure you complete all
the relevant tests to reduce the risks.”
Maintaining the legacy mainframe was
expensive, and the limited availability
of mainframe experts in its mainframe
operating system in Israel was constraining
the flexibility of its IT infrastructure. The
mainframe environment was running over
10,000 programs written in Natural and over
120 programs written in COBOL, with over
2,000 batch processes activated in specific
mainframe partitions by JCL. The mainframe
environment was supporting development,
quality assurance, testing, and production
environments, and mission-critical back
oice applications such as those supporting
clearing and settlement were on a mainframe
running the VM and VSE operating systems.
TASE also deployed the Adabas database
management system on a mainframe.
TASE sought to eliminate the risks inherent
with legacy environment operations while
limiting its reliance of mainframe programs
and operations specialists, which were
becoming increasingly harder to find.
Management needed to reduce the costs
of maintaining the legacy applications while
avoiding downtime or any disruption to
operations. TASE also sought to standardize
hardware and software deployment to drive
down costs and increase IT agility.

By migrating its applications and moving to
a new platform, TASE could select the right
platforms for the right workloads at the right
price, while consolidating its IT environment
and adopting newer technologies and
increasing IT security. But migrating the core
platforms and moving crucial applications
can be a complex and potentially disruptive
undertaking, so TASE selected HPE
services to help the organization develop IT
strategies that minimize risk and maximize IT
investments so it could achieve its migration
goals safely and eiciently.
“It was very important for us to find one
supplier that could provide a full integration
project, including the hardware, the operating
system, and the migration project itself,”
explains Herstig. “We approached Hewlett
Packard Enterprise (HPE) because we were
familiar with HPE’s capabilities and could get
the benefits of HPE’s expertise at dierent
steps in the project.”
HPE had previously helped TASE move
to a new datacenter, and oered a holistic,
adaptive approach that enables smooth
mainframe migrations and simplifies the
migration process. HPE also oered proven
experience and a track record in migrating
critical mainframe applications, as well a lowrisk, high-value approach to migration.
By partnering with HPE, TASE has been
able to ensure business continuity without
disruption. This has allowed TASE to
implement application migration while
avoiding the need to make changes to the
business logic. Legacy applications were
migrated to HPE ProLiant DL 380 Gen8
Servers running Linux, and all Adabas
databases and programs written in Natural
were migrated to Linux. HPE oversaw the
rewriting of COBOL programs into the C
language, and all JCL was rewritten to run as
scripts.
HPE conducted extensive parallel testing
of mainframe-based and server-based
applications to ensure that there would
be no discrepancies while running various
production workloads over time, and
conducted extensive test case development,
execution, and automation to ensure the
quality and consistency of the new IT
environment before cutting over in early
2016. After only 20 months, the project
was successfully completed and HPE
educated and trained TASE development
and operational sta on the use of new
development tools and Linux.
All of the organization’s mission-critical
systems are now running on Linux, and IT is
now able to increase security, mitigate risks,
and streamline operations and management
by supporting the same environment for
trading and back oice applications. The
dependency on mainframe specialists
is eliminated, allowing TASE to increase
operational agility. This transformation was
completed on time and within budget, and
management expects to continue to meet
cost reduction and TCO objectives for the
migration.
Herstig concludes, “I’m very happy and
satisfied with HPE and the way they ran the
integration project, and I recommend HPE
to other organizations involved in such a
complex migration project.” This migration
supports TASE’s open system standards
strategy, and TASE expects a full return on
investment for its migration within less than
three years.
