WebLogic Server 12.1.3 WebSocket Emulation
• Browsers and firewalls may not support/permit WebSocket protocol
• WebLogic provides a fallback mechanism to emulate the WebSocket transport
behavior
• Client side with JavaScript library - OraSocket.js
• Server side with an adapter to handle HTTP Long Polling
● Developers
● Use the WebSocket API for Java to write your application
● Use the WebSocket JavaScript Object on the client
● Same codebase
● Looks and smells just like a WebSocket application
● Whatever happens behind the scene is not your concern

container
• Handle more users without adding more
application servers
• Restart/maintain applications/containers
without losing sessions
• Handle very large sessions efficiently
Scale Session, Cache and Data Grid as Independent Architectural Tier

Partitioned, Fault Tolerant, Self-Healing Cache
Coherence Clustered Caching Explained
• Cluster of nodes holding % of primary data locally
• Back-up of primary data is distributed across all other nodes
• Logical view of all data from any node
• All nodes verify health of each other
• In the event a node is unhealthy, other nodes diagnose state
• Unhealthy node isolated from cluster
• Remaining nodes redistribute primary and back-up responsibilities to healthy
nodes
