Banque Internationale Arabe de Tunisie (BIAT)
Sun Mainframe Rehosting Success Story.
Banque Internationale Arabe de Tunisie (BIAT), the largest private Tunisian bank, faced an urgent business challenge in an increasingly competitive banking industry. It had to provide faster and better service to its current customers in order to retain market share.
To meet this challenge, BIAT devised an ambitious plan for customer-focused banking solutions to keep clients loyal to BIAT bank services. BIAT selected Sun Microsystems Inc. to restructure its IT system, improve customer services in its existing 100-branch network throughout Tunesia, and add five new branch offices each year to fulfill customer demands for local service.
BIAT used a Sun Enterprise™ 10000 server and Sun Mainframe Transaction Processing Software to create this new IT system, migrating its banking applications from the existing mainframe to the Sun UNIX® environment, using a relational database, and adding Java™ interfaces for Internet and Web access.
The bank, which collects a rapidly-growing database of information daily from the 100 branches and runs batch jobs overnight, migrated 3,000 programs, 2,500 files, and 350 batch jobs with 6500 steps from the mainframe to the Sun Enterprise server, using a relational database, and adding Java interfaces for Internet and Web access. All applications were moved to the system in eight months and the mainframe was retired. The new system runs batch jobs 20 percent faster than the mainframe did, and there was minimal retraining required for developers on the new system.
Customer Needs Drive New IT System
BIAT’s mainframe was limiting the bank’s expansion and service capabilities. Running the core banking applications since the bank was formed in 1976, the system lacked flexibility to adapt to rapidly evolving market needs and customer demands. In addition, the existing system could not handle projected business growth, and high operation
BIAT’s requirements for a new IT system were very precise: the solution had to create and sustain client relationships by providing centralized customer information. It needed to fully automate standard transaction services and simultaneously minimize transaction servicing and operational overhead. And, finally, it had to be on a platform offering flexibility for future expansion and growth.
BIAT Finds a Solution with Sun
BIAT’s process began with decisions on which technologies to use and which vendors to rely on to deliver the solutions in a timely and cost-effective way.
Early on, BIAT was impressed by Sun’s success in migrating many legacy applications from mainframes to UNIX servers, especially large applications and difficult environments. Sun’s products, the Sun Enterprise 10000 server and Sun Mainframe Transaction Processing Software were good matches for BIAT’s needs. A key component of the Mainframe Transaction Processing Software was a Java product that offered a very efficient means to extend BIAT’s applications to the Internet for a complete eBusiness solution to improve customer loyalty. Sun’s software has been used to successfully migrate mission-critical enterprise applications from mainframe systems to open, affordable UNIX systems at more than 600 customer sites worldwide.
“We were impressed by the combination of Sun’s automated tools and the extensive migration experience of the team. The pilot went very smoothly and gave us confidence that the larger migration could be successfully executed,” noted Brahim Ben Ali, CIO at BIAT.
BIAT was looking for a reliable means to rehost its large applications in a UNIX hardware environment that offered mainframe-equivalent technology. The banking firm chose a fourprocessor Sun Enterprise 10000 server, which is designed specifically to meet the challenges of today’s data center. The server can be partitioned into sixteen dynamic system domains that can be created, resized, pooled and deleted on-the-fly in response to changes in application demand, helping to enable customers to run the most intensive, multi-terabyte applications for data warehousing, decision support, OLTP and data analytics on a single, scalable server. Sun is the only UNIX vendor to offer this mainframe-like feature.
“Sun is a trusted name in open systems environments and we knew our applications would run efficiently on this platform, helping reduce operating costs.”
