Business
Top Turkish bank
Eight million customers rely on Garanti Bank for a range of integrated financial services, including
pensions, leasing, asset management, brokerage and retail banking.
As Turkey’s second largest private bank based on asset size, Garanti has nearly 800 branches, more
than 3,000 ATMs, total assets of US$65 billion and an award-winning call centre.
In 2008, Garanti achieved the highest ordinary banking income growth of 22 percent, increased its
customer base by over one million and provided loans of more than US$44 billion.
Jointly owned by Doğuş Holding and GE Capital, Garanti’s customer-centric approach, dynamic business
culture, and commitment to technological innovation are keys to its success.
Challenge
Safeguarding customer loyalty and satisfaction
Garanti has developed ground-breaking practices for increased efficiencies and has accomplished many
firsts in the financial services sector. Its Internet banking platform is based on state-of-the-art
technology that provides services to nearly 1.3 million customers.
“Poor mainframe management could
result in unplanned downtime,
impacting customer loyalty.”
Adnan Can
Principal Mainframe Specialist, Garanti Teknoloji
IT is equally important to the bank’s extensive branch network, which is supported by centralised
systems, including a data warehouse, 135 terabytes of disk storage and an IBM z/OS mainframe.
With a throughput of 25,000 MIPS, this mainframe is central to the bank’s daily operations. As Adnan
Can, Principal Mainframe Specialist at Garanti Teknoloji, explains, “The mainframe supports key
business and financial transactions, such as banking, insurance and credit cards, as well as legacy
applications. Poor mainframe management could result in unplanned business downtime, which could
impact both customer loyalty and satisfaction.”

Garanti Teknoloji uses a number of CA z/OS mainframe products to help enhance performance and
simplify management. These include:
• CA NetMaster: streamlines network management and safeguards performance
• CA Top Secret®: strengthens security, streamlines administration and enhances auditing capabilities
• CA Detector for DB2 for z/OS: identifies and addresses applications causing poor performance
• CA Fast Unload for DB2 for z/OS: improves data availability by reducing the time to unload data
• CA Subsystem Analyzer for DB2 for z/OS: accelerates performance tuning and analysis
• CA Gen: provides agile development methods for designing, modernising and implementing
mainframe applications.
“Authorised members of the team
can now update CA Technologies
products at the click of a button.”
Adnan Can
Principal Mainframe Specialist, Garanti Teknoloji
“We were reliant on manual processes to maintain and install these products,” comments Can. “With
a lack of experienced mainframe specialists, we needed to streamline mainframe operations as much
as possible.”
Solution
Simplifying management of business-critical mainframe
To help resolve its mainframe operational challenges, Garanti Teknoloji deployed CA Mainframe
Software Manager (CA MSM) in 2009.
Part of CA Technologies’ Mainframe 2.0 strategy, the solution simplifies the installation and
maintenance of the company’s z/OS software suite. As Can confirms, “Authorised members of the team
can now install and update CA Technologies products at the click of a button regardless of whether
they have any specialist mainframe knowledge.”

Garanti has therefore extended access to CA MSM beyond its small mainframe team to individual
support groups to help improve efficiency.
Ozgur Coskuner, Manager of Network Management at Garanti, comments, “Prior to deploying CA MSM,
our team was unable to make changes to mainframe software solutions, which impacted the network
maintenance and installation schedule. With the CA Technologies solution, we can not only install our
own fixes but also rollback and restore if we encounter any issues.”
Thanks to CA MSM’s user-friendly Web-based dashboard, individual IT teams can also see what fixes
have been deployed by their colleagues to prevent duplication of effort.
“We used to find it difficult to track what software upgrades and patches had been applied, which
made problem and incident management more complicated and time-consuming,” comments
Coskuner. “With CA MSM we can quickly see the patch status and download any new fixes that have
become available.”
Benefit
More efficient processes safeguard quality of service for customers
Garanti can now manage its mainframe environment more efficiently with software being installed in a
matter of minutes rather than hours.
“With CA MSM, the process took just
five minutes. In the past it could
have taken up to four hours.”
Adnan Can
Principal Mainframe Specialist, Garanti Teknoloji
“When we used CA MSM to install CA NetMaster, the process was completed in just five minutes,”
comments Can. ”In the past this type of software installation could have taken up to four hours. This
represents a productivity saving of up to 400 percent.”

As well as improving efficiency and freeing up resources, CA MSM has helped Garanti:
• Reduce business risk
• Decrease its reliance on expensive and scarce mainframe skills
• Improve quality of service to its customers.
“By simplifying elements of our mainframe operations, we can safeguard the performance of the
environment and make better use of our IT resources to meet the needs of the business, which is key
to providing a high level of service to the bank’s customers,” comments Can.
