CASE STUDY FOR GOVERNMENT
+ Overview
AltibaseAltibase is provider of In-Memory data solutions for real-time access, analysis and distribution of high volumes of data in mission-critical environments.
Korea Advanced Institute of Science and Technology (KAIST)
KAIST is a public research university located in South Korea.
SummaryAltibase helped KAIST accurately assess and process all historical and current account information seamlessly.
In-Memory Database Solution
+ ProblemsKAIST suffered from an inadequate database management system (DBMS) performance and reliability with their online enrollment system.
Due to massive logon attempts during the enrollment period, KAIST’s DBMS could not handle the load. As a result, logon attempts were unsuccessful and in-use disconnections were widespread. This led to inevitable system down times.
Increased number of online lectures led to an increase in online users. As the number of connecting sessions increased, KAIST‘s DBMS could not keep up with the workload.
KAIST was in dire need of cutting edge technology to remedy their problems. As a result, KAIST’s profitability and reputation were suffering.
In-Memory Database Solution
+ Solution ALTIBASE HDB In-memory DBMS’ built-in High Availability (HA) -
Replication features allowed KAIST to effortlessly handle the increased capacity demand, while providing stability1.
The widespread system demands during enrollment periods proceeded glitch-free.
In-Memory Database Solution
1) KAIST installed ALTIBASE HDB in hybrid mode on an SUN FIRE 15k system with 1.2 GHz 8-core; 64 GB of memory with an Active-Active Replication configuration.
+ Results KAIST provided normal services during enrollment periods2.
Leveraging ALTIBASE HDB’s In-Memory DBMS drastically boosted performance speed3.
Leveraging ATLIBASE HDB’s Hybrid functionality, all historical and current account information accessed and processed seamlessly.
Readily available personal, proprietary and data-driven information permitted KAIST to process a vast number of course enrollments and online courses.
In-Memory Database Solution
2) KAIST’s previous DBMS system could handle at most 300-400 connecting sessions at any give instance. Now, KAIST’s DBMS can handle more than 1,000 connecting sessions without impacting overall system performance or stability.3) KAIST processed 800,000 transactions periodically in the legacy system.
