Korea Enterprise Data (KED) is a leading supplier of business credit reports on Korean midsize enterprises, including credit evaluations and ratings, financial statements, and credit history checks. It has the most comprehensive knowledge base on midsize enterprises in Korea, using 4.6 million enterprise information databases and a nationwide network of 250 credit research specialists and branches to perform its credit searches and analyses.
KED, which is jointly financed by government agencies and private finance companies, is a member of the international CreditAlliance network. It also partners with the world-renowned credit ratings agencies Standard & Poor’s and SINOSURE of China. KED anticipated a 4x surge in credit services for midsize enterprise information, credit searches, and data assessments from banks and other financial agencies. It required a highly reliable, secure, and sophisticated credit analysis system to store and manage large volumes of sensitive data, such as customers’ credit histories, and to rapidly respond to credit inquiry or evaluation requests from its banking and financial-institution customers.
The company implemented Oracle’s SPARC T4-4 server with Oracle SuperCluster T4-4 to consolidate 20 servers into a single platform, and built a next-generation credit analysis system to improve data quality and reliability. KED also deployed Oracle’s Sun ZFS Storage 7420 and Sun ZFS Storage 7320 appliances to provide data storage and backup for Oracle SuperCluster. The company improved system response time by 20x, completed data backups 7x faster, achieved 10x data compression, and improved customer satisfaction.
KED needed a stable credit analysis system to ensure credit-inquiry services’ smooth processing and providing reliable credit information to customers on time. For example, KED must deliver clear and accurate short-term credit default information to banks to enable small business loan approvals and processing. Delays in receiving the credit information can have a significant impact on the approval process.
“By consolidating 20 servers onto a single Oracle SuperCluster, we accelerated online transaction processing with Java application response time by 20x, accelerating credit analysis and report development, and helping us to meet customer expectations for rapid completion of credit business reports,” said No Mun Myung, manager, IT management department, Korea Enterprise Data.
KED previously performed online transaction processing (OLTP) and online analytical processing (OLAP) on separate servers, which was costly and required additional software installation, maintenance, and management to run.
By consolidating 20 servers onto a single Oracle SuperCluster, KED combined OLTP and OLAP operations on one machine. As such, it halved its number of database server cores from 32 to 16 and cut CPUs from 55 to 8, slashing power costs. The company also reduced its number of rack units from 160 to 40, saving space and minimizing data center rental costs.
Implementing Oracle SuperCluster also enabled KED to move closer to achieving its environmental goals by reducing energy consumption and cutting power expenditure from 28 kilowatts to 8 kilowatts per hour.
“Through server consolidation, we cut power and operating costs and reduced database license requirements—lowering total cost of ownership (TCO) and gaining a more efficient and streamlined business,” Myung said.
KED also implemented Sun ZFS Storage 7320 and Sun ZFS Storage 7420 appliances for data storage and backup. It used the storage as data domains for most customer tasks, such as web and web application server mail, and to provide database backup for Oracle SuperCluster.
“We achieved 10x database compression by applying Oracle Hybrid Columnar Compression technology on Oracle’s Sun ZFS Storage appliances, drastically reducing backup storage size to obtain a high degree of stability,” Myung said.
The combination of Oracle Hybrid Columnar Compression with Sun ZFS Storage appliance’s intelligent data caching, and high-speed, 40 gigabits per second InfiniBand network, accelerated workload processing, secured data integrity, and enabled KED to complete data backups 7x faster—in just 17 minutes instead of up to two hours with the legacy system.
In addition, using Sun ZFS Storage appliance’s snapshot and clone functions, KED can now rapidly duplicate databases without expanding storage capacity, completing tasks rapidly and at lower cost, without a negative impact on database operation, including tasks regarding statistical analysis, batching, and application development and testing. The company also simplified system management by using Sun ZFS Storage appliance’s DTrace Analytics functionality, enabling IT staff to easily manage and monitor storage usage with the intuitive and visual interface.
KED used Oracle Enterprise Manager Ops Center to monitor hardware performance, simulation, and the operating system for Oracle SuperCluster. KED also implemented Oracle Solaris Cluster to ensure high availability, security, and scalability for Oracle SuperCluster and achieve business continuity for its business-critical credit analysis system.
Finally, the company upgraded its Oracle Database to ensure smoother service, improve compression speed, and expand storage space.
KED selected Oracle over other vendors for its ability to deliver a powerful and integrated platform to optimize performance of the company’s legacy Oracle solutions, such as Oracle Database, Oracle WebLogic, and JAVA developer kit; improve data management and delivery; and reduce total cost of ownership.
“Oracle SuperCluster clearly surpassed the other vendors we assessed by demonstrating superior data compression, storage access speed, and data backup capabilities,” Myung said. “It provides a sophisticated infrastructure that enables us to support massive growth of credit data volumes and transactions in the future.”
KED began building its business specifications for its infrastructure advancement project in December 2011 and assessed solutions from three vendors.
The company selected Oracle as its preferred supplier, based on the superior performance of Oracle SuperCluster through its benchmark test. It deployed the new environment over a period of eight months, going live in March 2013.
KED engaged Oracle partners Daesang Information Technology Company to oversee system procurement and installation and UGENS to manage data and program migration.
“Daesang Information Technology Company and UGENS provided expertise in building optimal customized services for our data migration policies. Their committed efforts and differentiated services delivered an integrated and high-performance Oracle platform that will meet our current and future needs,” Myung said.
