Exalogic Software Overview

Oracle Exalogic Elastic Cloud Software (EECS) includes performance optimizations for
Oracle SuperCluster T5-8 to improve input/output, thread management, and request handling
efficiency.
Additional optimizations include reduced buffer copies, which result in more efficient input/
output. 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 InfiniBand support for Sockets Direct Protocol, which
reduces CPU utilization as network traffic bypasses the TCP stack.
