2. The following is intended to outline general product
use and direction. It is intended for information
purposes only, and may not be incorporated into any
contract. It is not a commitment to deliver any
material, code, or functionality, and should not be
relied upon in making purchasing decisions.
The development, release, and timing of any features
or functionality described for Oracle’s products
remains at the sole discretion of Oracle.

3. Presentation Objectives

6. Enterprise Application Scalability
Challenges
Ease of Scaling
Service Clients • Grows and scales
• Browsers, supplier and partner clients, application naturally
clients, mobile apps, and other service consumers.
• Increasing load
Service Implementation • Computationally
• Custom applications, BPM processes, service bus intensive work
endpoints, UI services, and other service providers. • Highly dependent on
shared services
Shared Services • Complex and
• RDBMS, cloud services, supplier and partner expensive to scale
services, mainframe applications, and so on. • High latency SPOB
and SPOF

7. Traditional Clustering
• Dependent on shared service
Service Clients latency
• Increase in size of cluster
leads to increase in load on
shared service
Service Service Service
Node 1 Node 2 Node N • Inconsistent view of data
across cluster nodes
Cached Cached Cached
Objects Objects Objects • No possibility for in-memory
analytics
• Limited in-memory cache
due to
Shared Service • Capacity implications
• Java garbage collection

8. Enters the Coherence Data Grid
Ease of Scaling • Clustered Caching
• Provides a consistent view
Service Clients of data across cluster
• Partitioned Caching
Service Service Service • Increase in size of cluster
Node 1 Node 2 Node N adds capacity but does not
decrease performance
In-memory Data Grid • Distributed Data
Processing
• Enables a distributed
Shared Services platform for high
performance in-memory
analytics

9. How to Integrate with Coherence
Two Options
1. Custom integration through Coherence API
• For Java, C++, and .NET applications
2. Through Existing ‘Switch-On’ Integrations
• Oracle TopLink Grid – For JPA object relational
data offload
• Oracle Service Bus – For service results
caching
• Oracle Coherence*Web – For HTTP session
caching

10. Coherence Basic Inteface
Custom Integration
• Application uses NamedCache neCache =
CacheFactory
Coherence API to .getCache("NetworkElement");
store/access its data
…
• Application cache
NetworkElement ne = new
properties are configured NetworkElement(“ID-321”, “OC-
externally through XML 196”, “Nortel Networks);
file neCache.put(“ID-321”, ne);
…
• Basic cache access
through NamedCache NetworkElement ne =
neCache.get(“ID-321”);

15. Reliability
Partitioned Fault Tolerance
• Automatically and
transparently manages
the fault tolerance of
your data.
• Backups are
guaranteed to be on a
separate physical
machine as the primary.
• Backup responsibilities
for one node’s data is
shared amongst the
other nodes in the grid.

16. Write Behind
• All data writes occur through cache
• Updates to the cache are written asynchronously to
the data source

17. Coherence Elastic Data | In-Memory Cache
Seamless management of data
across memory and disk-based Coherence
devices, including RAM, Solid
State Disk (SSD), and Storage
Area Networks (SAN)
RAM
Tuned journaling algorithms
enabling near memory speed
access to data regardless of FLAS
storage medium H
4x increase in data capacity
Very high performance, low latency DIS
Massively concurrent reads and K
writes (to external storage)

20. Presentation Objectives
To Understand…
1) How Coherence improves performance, enables
linear scalability, and provides availability for
shared services
2) How Coherence leverages its distributed
architecture to enable high performance analytics
and processing on application domain objects
3) Coherence’s roadmap and strategic direction

21. Data Processing
Parallel Query
• Programmatic query mechanism
• Queries performed in parallel across the grid
• Standard indexes provided out-of-the-box and supports implementing
your own custom indexes

22. Data Processing
Continuous Query Cache
• Automatically, transparently and dynamically maintains a view locally
based on a specific criteria (i.e. Filter)
• Same API as all other Coherence caches

23. Data Processing
Invocable Map
• The inverse of caching
• Sends the processing (e.g. EntryProcessors) to where the data is in the
grid
• Standard EntryProcessors provided Out-of-the-box
• Once and only once guarantees
• Processing is automatically fault-tolerant
• Processing can be:
• Targeted to a specific key
• Targeted to a collection of keys
• Targeted to any object that matches a specific criteria (i.e. Filter)

24. Data Processing

25. Data Processing
Events
• Java Bean Model
• Key-Based
• Filter-Based
