2. １．About trading system • JASDAQ system introduced in 1991 was developed as the infrastructure for the auction trading system and information transmission. • In parallel with the adoption of the market maker system in 1998 for enhancement of liquidity, the market make trading system was newly added to the entire JASDAQ system. The system was developed as the first trading system using an open server in the securities market. • In 2003, API (Application Program Interface) system was started as a breakthrough in the securities market of Japan and as the completely new system pioneering the market as an open system of the twenty-first century.

3. ２．History of ＪＡＳＤＡＱ system

4. ３． System reinforcement Number of Deals & Performance of JASDAQ System mil/day 4 System reinforcement Jun. 2006 : *Order processing capability 4mil. /day ← 2.1 mil./day Mar. 2006 : *Order processing capability 2.1mil. /day ← 2 mil./day Jan. 2006 : New computer center operation *Order processing capability 2mil./day ← 1.4 mil./day *Order processing speed About twice as fast compared with the past 2005 : The system is reinforced. four times. 3.5 Processing performance 4million/day 3 （Jun.26 06） ×４ 940,000 the maximum results 2.5 （Jan.18 2006） 2 Twice or more the ability at the peak are always secured. 1.5 1 0.5 0 Y2003 Y2004 Y2005 Y2006

5. ４．For introduction of next-generation system • Schedule for operating season : Autumn 2009 • Performance target • Order processing capability : 4mil./day （NC） • Order processing number : 18thousand./min(NC) • Order processing speed : 35m/sec（existing system：300m/sec） • System architecture • Adopted decentralized data processing system by blade server • Actualize cost-saving & added scalability and reliability • OS ： Adopted Linux-based leading system, such as trading server • Processing mode : Adopted high-speed processing by synchronous memory functions (Japan's first system in securities exchange industry) • Scalability ：Expanded CPU & Trading server • Actualize added-order processing number & capability in rapidly

7. ６．Scalability （blade server） • 　System architecture • Adopted decentralized data processing system by blade server • Actualize cost-saving & added scalability and reliability *Additional blade server *Easily reinforcement

8. Trading server (Main) memory 　Order memory memory Trading server (Stand-by) ７．High Speed （In-Memory Database） • Receive data is transferred to two or more preliminary servers. • 　Receive data is guaranteed. • 　Receive data is needed to ultrafast access. Layout in memory

9. ８．Synchronous memory functions • 　Receive data (ex: order data) is automatically synchronized. • 　Main server & Stand-by server. • 　Unexpected system failure (Main server). ultrafast changeover. Trading server (Main) failure memory 　Order synchronous memory Changeover memory Business to Continue memory Trading server (Stand-by)
