Exalogic Software Overview

Oracle EECS includes performance optimizations for SuperCluster systems to improve I/O, and thread management, and request handling efficiency.

Additional optimizations include reduced buffer copies, which result in more efficient I/O.  Finally, session replication performance and CPU utilization is improved through lazy deserialization, which avoids performing extra work on every session update that is only necessary when a server fails.

WebLogic Server clusters can be configured with cluster-wide optimizations that further improve server-to-server communication. The first optimization enables multiple replication channels, which improve network throughput among WebLogic Server cluster nodes. The second cluster optimization enables IB support for Sockets Direct Protocol, which reduces CPU utilization as network traffic bypasses the TCP stack.
