"The brakes are off, and the workload is no longer artificially constrained. We’re already seeing transaction volumes increase as we’re better able to serve the needs of our customers." - Adem Onar, General Director of service delivery, Republic of Turkey Social Security Institution
Republic of Turkey Social Security Institution
System z Software
The Social Security Institution (SSI) for the Republic of Turkey was established to provide citizens with equitable, easily accessible social and universal health insurance. The organization is responsible for implementing social security policy in accordance with national development strategies, coordinating public agencies in the social security sector and collaborating with the European Union to establish international policy agreements.
To accommodate greater workload demands, the Social Security Institution (SSI) needed to boost its IT environment’s processing power and scalability
IBM Business Partner Vizyon Bilgi Teknolojileri helped the SSI upgrade its IBM® DB2® 8 for z/OS® software directly to IBM® DB2® 10 for z/OS® software to minimize upgrade conversion time
The SSI decreased its CPU per transaction by up to 23 percent and quadrupled its workload capacity, allowing the organization to improve service delivery.
The Social Security Institution (SSI) for the Republic of Turkey was established to provide its citizens with equitable, easily accessible social and universal health insurance. The organization is responsible for implementing social security policy in accordance with national development strategies, coordinating public agencies in the social security sector and collaborating with the European Union to establish international policy agreements.
In the early 1990s, the SSI implemented IBM® DB2® 2.2 for z/OS® data server software to create a resilient, highly available IT environment to deliver its critical support services. The organization continued to use the software over the next two decades, performing regular version upgrades. Following the release of IBM DB2 10 for z/OS data server software in 2010, the SSI wanted to upgrade its DB2 8 for z/OS data server software directly to the latest version by using the technology’s skip migration feature.
“SSI had a very good experience with DB2 skip migration when it jumped from DB2 5 to 7 some years ago,” explains, Cüneyt Göksu, IBM Gold Consultant for IBM Business Partner Vizyon Bilgi Teknolojileri. “When the organization had the opportunity to go directly from DB2 8 to 10, it seemed like a natural choice.”
With the upgrade, the SSI hoped to increase processing power and improve its IT environment’s scalability. “Two of three DB2 production subsystems were struggling to keep up with increasing workload demands due to virtual storage and CPU constraints,” says Göksu. “The chance to upgrade to DB2 10 and address these issues was very attractive to the business.”
In August 2011, the SSI teamed with Vizyon Bilgi Teknolojileri to launch its upgrade project, focusing on all necessary preparation work. The organization brought its 16 DB2 for z/OS data servers up to current maintenance levels and addressed additional technical prerequisites.
The SSI ordered its DB2 10 for z/OS product tapes in January 2012 and successfully upgraded all subsystems to DB2 10 for z/OS conversion mode over the next four months. In August 2012, the organization completed its smooth transition to DB2 10 for z/OS new function mode.
By eliminating the need for two single-version upgrades, the skip upgrade saved time and money for the SSI. Additionally, the upgrade delivered performance benefits well beyond the organization’s expectations. “The brakes are off, and the workload is no longer artificially constrained,” says Adem Onar, general director of service delivery for the SSI and IT Coordinator for Ministry of Labour and Social Security. “We’re already seeing transaction volumes increase as we’re better able to serve the needs of our customers.”
