In the current global enterprise business environment, with the millions of applications running across mobile phones and tablets, mobile brings more business opportunities for value added services but also brings more challenges to existing systems. Data is being accessed at a rapidly increasing rate to service mobile applications and the workload is becoming a burden to back-end servers. The solution to this problem is caching, and IBM® WebSphere® eXtreme Scale or the WebSphere DataPower® XC10 Appliance can cache frequently used data, thereby improving the performance of mobile applications and reducing the traffic to these back-end applications.
If you're problem is that you need better performance on an increasingly higher traffic that mobile applications bring, in memory caching is your solution.
Read through the Enterprise Caching in a Mobile Environment Redbook to see how WebSphere eXtreme Scale, WebSphere Liberty Profile, and IBM Worklight can help you solve these problems. And better yet, we have an entirely working sample that can show you show easy it is to write an application using these technologies!

The InverseRangeIndex sample is provided for a quick introduction to the Inverse Range Index feature. It consists of shell and batch scripts designed to start a simple grid with very little customization needed. The sample shows how to use WebSphere eXtreme Scale for indexing Range style data that can be looked up efficiently. This sample can be run with WebSphere eXtreme Scale or IBM DataPower XC10 Appliance.
If you have data contains range attributes, you can use Inverse Range index to index over range attributes and use index to search data by range criteria. A range attribute is defined as a segment with start and end value. Index searching means to find data that has the range that contains the range criteria.
Consider the following Product promotion data:
"Product", "Condition" and "Country" are non-range attributes. Where as "Start Promotion" and "End Promotion" are one
set of range style attribute for Promotion Date. Similarly "Min. RAM" and "Max. RAM" are another set of range attribute for RAM.
As per the preceding data Index searching for the price of SmartPhone_1 on 06/01/2007 with 4GB RAM that is in Good condition will be sold in US is $550.
This sample should be extracted into the <installRoot>/ObjectGrid/samples directory. The resulting directory structure should look as follows:
* Substitute the path to the eXtreme Scale installation root directory or the root file path of the extracted eXtreme Scale trial <installRoot>
This sample includes a client subdirectory which demonstrates how to use WebSphere eXtreme Scale for indexing Range style data that can be looked up efficiently.
Running the sample
1. Open a terminal or command-line window:
Windows: set JAVA_HOME=<java home>
UNIX: export JAVA_HOME=<java home>
2. CD <installRoot>/ObjectGrid/samples/InverseRangenIndex
3. Start a catalog server:
Windows: start runcat.bat
UNIX: ./runcat.sh &
Wait several seconds for the message:
CWOBJ1001I: ObjectGrid Server cs0 is ready to process requests.
4. Start a container server:
Windows: start runcontainer.bat server0
UNIX: ./runcontainer.sh server0 &
Wait for several seconds for the message:
CWOBJ1001I: ObjectGrid Server server0 is ready to process requests.
5. Run the test client for Product Data:
The test client shows several operations on the grid including an insert and perform lookup in
index on a Simple Range Index.
6. Run the test client for Policy Data:
The test client shows several operations on the grid including an insert and perform lookup in index on a Multi Range Index.

Developing Applications for IBM WebSphere eXtreme Scale V7.1
The content of this video is the first unit from the IBM WebSphere Education course ZA974 Developing Applications for IBM WebSphere eXtreme Scale V7.1. This course covers the basic architecture of WebSphere eXtreme Scale, its programming APIs, and administrative concepts related to it. The course begins with an overview of the WebSphere eXtreme Scale product and grid technology. Students then learn how to use the various WebSphere eXtreme Scale APIs and programming models that are available for application development, including ObjectMap, EntityManager, and DataGrid. In addition, students learn best practices for deploying and administering WebSphere eXtreme Scale solutions.
