– Part of HTML5 Standard by W3C with EventSource JavaScript Object

– Many HTTP messages on a single connection

– Enables reconnection and replay capability with Last-Event-ID HTTP header tracking

• Automatically included and registered by the WLS JAX-RS 2.0 shared-library

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


WebLogic Server 12.1.3 - Java API for JSON Processing

• WebLogic Server implementation based on Java EE7 RI

• Standard Java API to generate and parse JSON

– Included in Java EE 7

– Included as module with WebLogic Server 12.1.3

• Has an Object model API to represent JSON – Similar to DOM API in XML world

• Has a Streaming API to produce/consume JSON

– Similar to StAX API in XML world

WebLogic Server 12.1.3 – XA Without TLOGs

• Improve performance, manageability of XA apps

• No TLOG I/O – up to 3x throughput improvement

• No TLOG replication requirements for DR

• How it works

• Define “determiner” resource - last to prepare/commit

• Tx recovery based on resource state and determiner

• Single TM w/no LLR or JTS – no TLOG required

• Multiple TM – reduced writing to TLOG

• Multi-phase delivery of this features

• Multiple TM XA in with no TLOG in 12.2.1

Oracle Coherence 12c


Modern Best Practice Caching Architecture Pioneered By Coherence

First Generation Cache Solutions

Difficult to scale, complex to synchronize, limited capacity

Modern Best Practice Cache Solutions

Easy to Scale, Clustered, Synchronized, Advanced Capabilities


Application Server with Coherence

• Offload session and application data management from the app server tier

• Scale tiers independently

• Coherence*Web

• Decouple session management from web 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

?


• Detect and reflect database changes in cache in real time

• Leverage existing technologies

– GoldenGate, TopLink Grid

• Broaden applicability/usability of Coherence

• No code change

Memcached Adaptor

• Migrate from Memcached

• Use popular Memcached Clients

• Leverage Coherence benefits and features

– Scalability, availability, and reliability

– Data source integration including HotCache

– Security • SASL PLAIN authentication mechanism using

Coherence JAAS Identity Asserter

• Integrates with the Coherence Proxy Security framework for custom authorization.
