LG Card

LG Card is Korea’s biggest credit card and consumer credit provider. It has nearly 9 million active customers, 2385 of employees and its assets rose to 12trillion won since it has started its business only with 140.000 of customers in 1998. LG Card’s business main principal is focusing on customer value and it has developed consumer-friendly financial services. Its basic strategy is Continuous Profitable Growth and to achieve it, it is now managing profitable financial products by offering reliable products and services which bring high-return profits. It also tries to minimize risks through self-developing RMS (Risk Minimizing System) to raise its global credibility. At the same time, LG Card concentrates on the on-line business management to adjust rapidly changing world e-biz environment effectively. LG Card is actively participating new business which is highly related with company’s core competitiveness while it strengthens existing business.

Situation

LG Card is highly required to introduce APM monitoring tool in order to monitor WAS running in a MainFrame environment and to solve a problem caused when existing systems are not communicate with each other. It also faced a challenge to provide stable service with high performance to customers especially, it needed real-time error monitoring solution for 24 hours to secure its competitiveness in the market.

MainFrame When errors or problems occur in WAS system running on the MainFrame, engineers or system administrators was faced with the difficulties to monitor them due to lack of solution. Of course, there are many system monitoring tools running on the MainFrame, however, such tools just shows system status rather than showing application status specifically. Those UIs are also inconveniently designed and organized with a lot of useless menus. Along with this problems, LG Card also needs CICS transaction monitoring not only WAS and application monitoring

Mid-size Server While Jennifer was introduced to monitor MainFrame WAS in LG Card, it is needed to monitor WAS running on the mid-sized systems (Unix) as well. Therefore, LG Card purchased a Jennifer site term license about its enterprising projects. After testing such projects and launching, determination of root cause and stabilization were major challenges for consumers. In addition, engineers desperately desired a monitoring solution running on the real server O/S environment without happening any performance problem against working system.

Solution ` Jennifer is installed to monitor WAS of MainFrame because Jennifer is able to manage performance effectively by providing intuitive information about application in real-time. Jennifer measures to the problem immediately as well.

Mainframe WAS Monitoring OS : Solaris 8,9 / AIX 5.2,5.3 / zOS WAS : JEUS 4.2,3.X / WebSphere 6.0 DBMS : DB2 8 / Oracle 9i JVM : IBM JDK 1.4.2 / SUN JDK 1.3,1.4 Mid-size Server and MainFrame System Integrated Monitoring Customizing for WAS monitoring running on the MainFrame Customizing for LWST

Jennifer showed detailed application information about main frame and its simplified menu configuration let user analyze problems easier. Jennifer also provided integrated monitoring services about WAS/Application/CICS Connection (CTG).

Benefit

As Jennifer make it possible to monitor applications in WAS, engineers working in LG Card can access core data to solve performance problem. Therefore, the company can minimize downtime and control the total memory usage and load capacity with Jennifer’s continuous monitoring.

After experiencing Jennifer on the MainFrame, system administrators highly preferred to use Jennifer for other Unix-based web systems. Currently, Jennifer is used for load test before the system is opened and usually for the monitoring purpose to be proactive against performance problem. Jennifer creates benefits by reducing costs thanks to its speed problem solving competency compare to the past.
