Architecture of ClusterPlus
Consisting of the ClusterPlus engine and Admin server, ClusterPlus is installed in a module on a WAS base. Environment configuration information for session clustering is managed through DBMS or the file system.
Main functions of ClusterPlus
ClusterPlus is a smart web session control & clustering solution that provides HTTP session clustering and session management functions to ensure the high functionality of WAS.
Session Failover
- Automatic recovery of client session in case of failure/li>
- Support session replication and session sharing
- Control of simple session information
WAS/Application Integration
- Session clustering between different types of WAS
- Session clustering between different types of web applications
- Session integration between systems
Session Integration Management and Monitoring
- Session key management function
- WAS session integrated monitoring
- Session status by total/node
- Classification of replication target/non-replication target sessions
- Session creation/expiration statistics
Advanced Session Control
- Lightweight SSO support
- Login control (multi-login protection) support
- Login user management
ClusterPlus is applicable to every java based WAS without a single correction of application source code, as well as supports session clustering between different kinds of WAS. Along with integration of sessions between different kinds of WAS, ClusterPlus also provides SSO(Single Sign On) function through session sharing between systems consist of sub-domains, enabling to remain logged in even when connected to different work systems.

Benefits of ClusterPlus
ClusterPlus is a smart web session control & clustering solution that provides HTTP session clustering and session management functions to ensure the high functionality of WAS.
Service Quality Improvement
- Session failover
- Improved service stability
- Increased user satisfaction
- Increased productivity (increased sales, work protection, etc.)
Maximization of Resource Use
- Work-specific WAS integration
- WAS integration between different types
- Recycling of Standard Edition WAS
Cost Saving (Enterprise Edition WAS vs. Standard Edition WAS + ClusterPlus)
- Reduction of adoption costs by 40 to 60% compared to commercial Enterprise Edition WAS
- Reduction of SSO adoption costs
- Reduction of maintenance costs (40 to 80% savings)
