2 Content overview Oracle Grid Computing context What is Application Grid? Coherence JRockit JVM Bundling & pricing Extreme performance complementary solutions Guide to useful resources Conclusions

3 Oracle's view of Grid Computing OEM Grid Control

4 Oracle's view of Grid Computing Oracle Application Server EE clustering + WebLogic Server clustering OEM Grid Control

5 Oracle Fusion Middleware Complete, Integrated, Hot-Pluggable

6 This is what s under that umbrella WebLogic Application Grid is listed in the Price Book. Other bundling is available also.

7 Application Grid - targets Who would be interested? Clients who need Middle-tier based on object-oriented data structures within their application logic Middle-tier with critical performance and scalability Middle-tier with critical availability under duress

8 Coherence Acquisition of Tangosol 2007 Ideally suited for use in computationally intensive, stateful middle-tier applications Container-less Clustering of Java Processes Data Structures to manage Data across a Cluster / Grid Materialized Views of Data (not the usual kind!) Parallel Queries and Aggregation Object-based Queries Parallel Data Processing Parallel Grid Processing MAN + WAN Connectivity Works with non-oracle application servers like Websphere and JBOSS

9 Coherence Some uses Caching state in the Application-tier Relieve load on lower-tier systems Reliably managing state in the Application-tier Scaling out application state (in the application-tier) In-Memory Http Session Management Temporary System of Record for Extreme Transaction Processing

10 Coherence Real Time Client Provides a real time connection to the data grid, allow client-side event processing, continuous queries, and coherent in-process caching of data. Avoids repetitive enquiry to review state. Requires Coherence Grid Edition (or WebLogic Application Grid)

11 Coherence Consensus-based integrity Uses a proprietary network stack called TCMP TCMP = The Consensus Management Protocol TCMP = Tangosol Coherence Management Protocol Peer-to-Peer Unicast-based Data Tranmission Protocol Optional support for Multicast Significantly more advanced features than TCP/IP Flow Control, Cluster-Wide Security, Packet Bundling, Multi-way (switch-less) Routing Out-of-band consensus information

12 Coherence Consensus-based integrity Coherence Consensus = an agreement between a set of processes as to the membership of a cluster at a point-in-time Coherence Consensus enables an unambiguous dynamic failover plan to always be in place Coherence Consensus enables reliable partitioning of Data and Services No overlap No missing responsibilities No ambiguity

13 Application Grid online demo samplers Scaling Application Server and Grid tiers

14 Application Grid online demo samplers Integrated, automated scale-up of both tiers

15 Application Grid online demo samplers Impact of Java Garbage Collection

16 Application Grid online demo samplers JRockit RealTime smoothes out the response time

17 Coherence Bundling/Pricing All relevant products are available both as NUP or Processor metric Note 1 : Processor means cpu socket for SE, otherwise cores * factor Note 2 : 10 NUPs minimum per Processor Coherence available as SE, EE or Grid Edition (consult matrix for details, see later) NB Grid Edition needed for WAN support WebLogic Suite includes WL Operations Control, JRockit Realtime, Coherence EE as well as other components such as WL Server and Oracle AS. WebLogic Application Grid bundles Coherence Grid Edition, JRockit Realtime, WL Operations Control and OEM middleware managements packs

18 Coherence Bundling/Pricing Packaging Notes: In Oracle WebLogic Suite, Oracle WebLogic Operations Control manages applications running on server instances of Oracle WebLogic Server Enterprise Edition and Oracle Coherence Enterprise Edition deployed in combination with WebLogic Server in the same tier. In Oracle WebLogic Application Grid, Oracle WebLogic Operations Control can manage more sophisticated scale-out architectures containing Java EE applications running on Oracle WebLogic Server, Java applications running on any standard implementation of Java SE (including Oracle JRockit Real Time) with Oracle Coherence Grid Edition deployed in a separate tier for unlimited data scalability..

19 Extreme Performance - Complementary Solutions

20 Extreme Performance Complementary solutions Times Ten Times Ten (aka In-Memory Database Cache) Acquisition in 2005 Like the Oracle Database Server, a SQL-based RDBMS. It s compelling characteristic is the database must fit in memory Therefore very fast and consistent response time. Full Read/Write behaviour with protection of changes. Design discipline lies in finding the right data to include. Replication to/from Oracle Database (home to larger set of data). Replication between Times Ten instances for scalability/resilience.

21 Extreme Performance Complementary solutions Times Ten Cache Connect to Oracle Option Data synchronization between TimesTen and Oracle can be transparent to application logic TimesTen Cache Group TimesTen updates to Oracle Automatic Propagation or manual Flush Oracle updates to TimesTen Full refresh Incremental refresh Automatic or Manual Based on concept of Cache Groups Propagate Oracle DB Refresh

24 Guide to useful resources OTN Coherence Launchpad Coherence Knowledge Base..for Java for.net for C++

25 Guide to useful resources Coherence Editions feature matrix Coherence Data Grid Collateral Coherence case studies Application Grid online demo

26 Guide to useful resources Coherence Incubator Sample implementations for common design patterns Coherence Oracle-by-Example Tutorials Creating Oracle Coherence Caches in Oracle JDeveloper Coherence for.net Framework data sheet

27 Conclusions Coherence supports.net and C++ clients as well as Java Use the Knowledge Base to understand Coherence. WebLogic and Coherence have been engineered to create a scalable, adaptive, highly-available infrastructure for deploying applications and the data objects they require for critical performance requirements. When extreme performance is required, evaluate the correct approach (Application Grid, TimesTen, CEP etc.) For Java applications, JRockit Real Time is a no-brainer for consistent highlyresponsive applications.
