Messaging InfrastructureDesigned to Scale to the Most Complex SOA Integrations

• Unit of Order– Messages tagged with same Unit of Order (UOO)

are processed in order

– Stronger ordering semantics than the JMS specification

• Unit of Work– Messages are grouped with a group identifier

– Messages at final destination become available only when entire group arrives

• Store and Forward Messaging

– Store messages on local server and forward to remote server when available

– Store and forward for clients to server and server to server

• Distributed Destinations– All queues and topics in a cluster appear as a

single logical destination to clients

– Provides high availability and scalability; parallel processing and load balancing

Messaging InfrastructurePerformance: Meets the Most Rigorous Throughput Req

• WebLogic 10 JMS is fast

– Up to 10X faster than previous WLS

releases

– Re-written file store and disk scheduling

extremely fast

– Database integration optimized with JDBC

and batching optimizations

• WebLogic JMS consistently beats

pure plays

– Synchronous writes 3X-6X faster than

competitors

– Message size 25%-4X faster for messages

between 1K->512K than competitors

Choice of IDE Solutions

• JDeveloper– Complete IDE for Fusion Middleware and Oracle

– Oracle ADF, SOA, WebCenter, Database etc.

– WebLogic support

• Oracle Enterprise Pack for Eclipse (OEPE)– Best of breed Eclipse bundle focused on Java Development

– Rich capabilities for WebLogic Java EE developers

• NetBeans– Open Source and tooling for Java RIs

– WebLogic and generic Java platforms (SE, EE, ME, JavaFX)

• Many other IDEs support WebLogic

– Support not as rich as JDeveloper, OEPE

31

High Availability

32

Transaction Log Persistence to RAC

• WebLogic historically has managed transaction state using a „tlog‟ file on a filesystem

• In order to recover transactions from a failed Server you had to migrate the filesystem or use shared storage

• WebLogic now offers the ability to maintain transaction logs in the database

• An HA database solution like Oracle RAC is strongly recommended

1. Queries are performed using

2. A find() will result in a get()

on the appropriate

Coherence cache. If found,

Entity is returned.

3. If get() returns null or query is

JPQL, the database is

queried with SQL.

4. The queried Entities are put()

into Coherence and returned

to the application.

50

Write-Behind JPA Entity CachingWebLogic Suite 11g & TopLink Grid

1. An application commits a

transaction with new Entities

or modifications to existing

Entities.

2. EclipseLink put()s all new

and updated Entities into

Coherence.

3. If a CacheStore is

configured, Coherence will

synchronously or

asynchronously write the

changes to the database,

depending on configuration.

51

Complete Database Entity OffloadWebLogic Suite 11g & TopLink Grid

1. Queries are performed using JPA em.find(..) or JPQL.

2. JQPL will be translated to a Coherence Filter and used to query results from Coherence. A find() will result in a get() on the appropriate Coherence cache.

• The database is not queried by EclipseLink.

• If Coherence is configured with a CacheLoader then a find() may result in a SELECT, but JQPL will not.

JRockit JVM PerformanceRunning on the World’s Fastest Java VM

• Complete implementation of Java

– 100% compatible with the Java SE and ”bug

compatible” with the Sun Java implementation

• Underpins Oracle Fusion Middleware product

stack

– One-stop shop for support issues

– Optimized stack

• Architected and optimized for server-side

Java

– High Performance

– Typical benefit is ~20% over Sun Java VM

based on benchmarking

– Customer feedback & surveys

* Oracle JRockit has been used for all world record SPECjbb2005 publications since Q2 2006. Best results based on Sun, JRockit and IBM as of

September 8, 2008 are (bops/bops per JVM): Sun Fire E25K (2105264/29240), SGI Altix 4700 (5180451/80945), IBM Power 595 (3435485/107359).

JRockit PerformanceJRockit Real Time: With Near Zero Application Pause Times

• Guaranteed maximum response times

– Java EE applications consistently under 100ms pause times

– Java SE tuned can be single-digit ms pause times

• Deterministic QoS under heavy load

– No code re-writes

• Remove weeks of tuning with simple declarative setting

– Deterministic setting

– Pause time target

InfiniBand Performance AdvantageUp to 12x Performance

• Network IO is critical

– #1 limiting factor for application

performance and scale

• Eliminate buffer copies

– From four to zero

• Use larger packet size to

reduce network overhead

– 64K instead of 4K packets

• Optimized for InfiniBand

– 3x throughput over 10 GbE

– 50% less latency via native SDP

Scatter Gather Input Output with InfiniBand

• Scatter gather input output collects 4K WebLogic chunks into

larger collections of chunks

• Chunks written onto larger MTU infrastructure of InfiniBand

• Instrumental in increasing throughput and reducing latency

ExaLogic Elastic CloudOptimized State Replication on Exalogic

• Single channel state replication per JVM

• Traditional two way RMI

• Full deserialization on secondary server

• State replicated over standard network

Standard WebLogic WebLogic on Exalogic

• Multi-channel state replication per JVM

• Optimized one way RMI

• Lazy deserialization on second server

• State replicated over InfiniBand

• Parallel muxer reduces lock contention

• Larger packet sizes (>=32K MTU for

SDP, versus 1.5K on 10Gb networks)

reduces processing overhead

• Rapid adjustment to varying workloads

(optimal adjustment is 24 threads)
