This sample and paper demonstrates XDF
data value evolution features showing you in a practical way the way an application would change data in an in memory datagrid. Websphere eXtreme Scale Version
8.6 introduces Enterprise Data Grid (EDG) capabilities using a new data
serialization format. The new data serialization format is called eXtreme data format (XDF). XDF includes the
serialization capabilities and the wire format that are used by eXtreme Scale
8.6 when you are using IBM eXtreme IO (XIO) as the communication protocol and the
COPY_TO_BYTES copyMode. XDF supports a cross-platform
serialization format that replaces Java serialization on object maps that have
a copyMode attribute value of COPY_TO_BYTES in the ObjectGrid descriptor XML
file. XDF maintains a set of compact
and efficient metadata for serialization; it makes the serialization and
de-serialization of object data much faster and uses less memory.
circumstances, the performance when serializing and deserializing objects using
XDF can be 20-30% faster than using the default Java serializer. In addition, the introduction of
XDF enables data value evolution. Application developers can evolve the
object/class definition that is used in the data grid without affecting older
applications that are using a previous
version of the class.
Download the guide on how to evolve your classes using the new XDF format in eXtreme Scale. This download also comes with source code to follow along and try out data evolution using XDF. This includes both a Java and C# Client to get your started!
The DataPower XC10 Appliance is a great way to get up and running with eXtreme Scale with an all included hardware package. WebSphere Liberty Profile Server is a lightweight Java EE runtime that can be deployed in seconds. With these two efficiently quick solutions, you can have your application accessing the data grid in record time.
This sample is a client that can run in the Liberty Profile and access the XC10 data grid. The sample shows how you can connect, and do basic CRUD operations to the grid. In the sample, you can store strings, but for further use, objects put into the grid as well.

This series focuses on the best practices for the integration of IBM®
WebSphere® eXtreme Scale DynaCache in WebSphere Commerce Server environments. WebSphere
eXtreme Scale is a distributed caching solution that is a popular provider of DynaCache in large
WebSphere Commerce Server environments. WebSphere Commerce Server customers have successfully
integrated WebSphere eXtreme Scale DynaCache in large and small production environments. While the
configuration of WebSphere eXtreme Scale DynaCache in a WebSphere Commerce Server environment is
simple, you need to pay special attention to the best practices for design, usage, operational
patterns, and tuning.
This three-part best practices series focuses on the tips and techniques involved in integrating
WebSphere eXtreme Scale DynaCache into WebSphere Commerce Server environments. The tips and
techniques in this series are based on successful launch experiences with some of the largest
WebSphere Commerce Server installations. The series includes information about designing, deploying,
configuring, and tuning applications in WebSphere Commerce environments.
When designing any WebSphere eXtreme Scale grid, you have to determine the amount of heap space,
number of WebSphere eXtreme Scale servers, amount of physical RAM, number of physical machines, and
a few other parameters. The DynaCache and general WebSphere eXtreme Scale grid sizing technique is
described in the "Dynamic cache capacity planning" topic on the WebSphere eXtreme Scale information
In any environment, it is important to monitor the health of the WebSphere eXtreme Scale grid and
collect statistical information about grid usage. These are a few simple strategies that can be used
to monitor the overall health of the grid and generate operational alerts when necessary.
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.
Directory Structure ------------------- This sample should be extracted into the <installRoot>/ObjectGrid/samples directory. The resulting directory structure should look as follows: <installRoot>/ObjectGrid/samples/InverseRangeIndex/
* 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
So, you have WebSphere eXtreme Scale in an OSGi environment running it as a bundle, or have any other third party software that requires you to bundle eXtreme Scale with your application. Fear not when it comes to upgrading!
eXtreme Scale includes
two bundles. Only one of the following bundles is required in an
bundle is the objectgrid.jar file
and is installed with the eXtreme Scale stand-alone
server installation and is required for running eXtreme Scale servers
and can also be used for running eXtreme Scale clients, or local,
in-memory caches. The bundle ID for the objectgrid.jar file
is com.ibm.websphere.xs.server_<version>, where
the version is in the format: <Version>.<Release>.<Modification>.
For example, the server bundle for this release is com.ibm.websphere.xs.server_8.5.0.
The ogclient.jar bundle
is installed with
the eXtreme Scale stand-alone
and client installations and is used to run eXtreme Scale clients or local,
in-memory caches. The bundle ID for ogclient.jar file
is com.ibm.websphere.xs.client_<version>, where
the version is in the format: <Version>_<Release>_<Modification.
For example, the client bundle for this release is com.ibm.websphere.xs.server_8.5.0.
You will have either these jar as bundles in your OSGi environment, but when putting on new fixpacks, you will have to use the installation manager for v22.214.171.124 and later. Use you use the Update Installer on anything that is v126.96.36.199 and earlier.
When you have eXtreme Scale integrated into a separate environment besides running standalone or inside of WebSphere Application Server, you just retrieve your eXtreme Scale jars from a standalone installation. Since you are upgrading, you may already that this standalone environment setup. If that is the case, just take your fixpack and install it to your standalone installation. In the <Install_root>/ObjectGrid/lib directory, you will see both objectgrid.jar and ogclient.jar have been updated. Take the required jar and replace it in your environment.
If you do not have a standalone environment to install the fix to, you will have to reinstall the original version you were using as standalone and then install the fix on top of that. In the <Install_root>/ObjectGrid/lib directory, you will see both
objectgrid.jar and ogclient.jar have been updated. Take the required
jar and replace it in your environment.
In your OSGi environment, you cannot dynamically update the objectgrid or ogclient jars. You must stop this bundle. You can then replace it in your plugins directory with the same name, or you can remove the previous bundle and install the new one via the osgi command line.
WebSphere® eXtreme Scale Version 8.6 has many new features including:
With the new enterprise data grid, Java and .NET applications can now interact natively with the same data in the same data grid.
A new REST Gateway provides simple access from other programming languages using HTTP.
WebSphere eXtreme Scale V8.6 delivers a faster, more compact serialization format called eXtreme Data Format (XDF), which is neutral to programming languages.
A new transport mechanism, eXtreme IO (XIO) removes the dependency on the IBM ORB, enabling easier integration with existing environments.
By installing the WebSphere eXtreme Scale Client for .NET, you can deploy .NET applications that access the data grid.
When you develop client applications that interact with the data grid, you might require queries that retrieve automatic, real-time results when new entries are inserted or updated. You can use the new continuous query function to be notified in your client Java™ virtual machine (JVM) when data is inserted or updated in the data grid. This feature makes data grid and data management easier for both developers and administrators.
Global index extends the built-in HashIndex plug-in, and it runs on shards in a distributed, partitioned data grid. Global index tracks the location of indexed attributes in the data grid and provides efficient ways to find partitions, keys, values, or entries using attributes in large, partitioned data grid environments. This feature is also integrated into the default dynamic cache function to provide higher performance.
Inverse Range index extends the built-in mapIndex plug-in and provides an efficient way to store and retrieve values for the keys that are within an established range; for example, a "sales promotion" or an "insurance policy" based on a range of dates or some other criteria.
Catalog and container servers can use High Performance Extensible Logging (HPEL) as an alternative to the basic log and trace facility.
The message center provides an aggregated view of event notifications for log and first-failure data capture (FFDC) messages for all servers in an eXtreme Scale domain. You can view these event notifications with the message center in the web console, the xscmd utility, or programmatically with MBeans.
The near cache invalidation function can be enabled to remove stale data from the near cache. When an update, deletion, or invalidation operation is run against the remote data grid, an asynchronous invalidation gets triggered in the near cache. This feature is integrated into the dynamic cache function as a configuration option to provide higher performance.
Use the new Multi-Partition Transaction support to read and write multiple partitions to provide a two-phase commit protocol to guarantee atomic updates.
Disk Overflow Support extends the capacity of the data grid by writing infrequently used data to disk.
Additional API Enhancements including upsert(), lock(), and OutputFormat, are now available.
General Configuration Enhancements, such as the nearCacheEnabled flag and Eclipse XML editor content assist support.
There are two ways to install eXtreme Scale on top of the lightweight WebSphere Liberty Profile. The free developer version can be seen on this post. However, if you have a production level environment, and need to install eXtreme Scale on top of Liberty using the Installation Manager, here's the way you would do it.
Installation Manager requires repositories to install products. Add a full WebSphere Application Server repository as well as a WebSphere eXtreme Scale repository by clicking File->Preferences->Add Repository
Go back to the main menu and click Install.
For WebSphere Application Server 8.5, choose the version and product you want, for example, "IBM WebSphere Application Server".
For WAS 8.5.5, Liberty is no longer packaged in the Full Install of WAS, instead, install "IBM WebSphere Application Server Liberty". If you install this way, eXtreme Scale 188.8.131.52 is the minimum required.
For WebSphere eXtreme Scale, there are two options to install, the client or the server (which includes the client)
IBM WebSphere eXtreme Scale Client for WebSphere Application Server v8
IBM WebSphere eXtreme Scale for WebSphere Application Server v8
Pick either to install the server and client, or just the client install of eXtreme scale. Click the Next button to continue.
There will be license information and such you may click through. Then, pick an installation directory to install the products.
On the next page, the features to install will appear for both WebSphere Application Server and WebSphere eXtreme Scale.
You are not required to install the full version of WebSphere Application Server, and you may pick just to install the Liberty Profile, but you may also install both as well. Make sure also that you install eXtreme Scale features as well.
When installing WAS 8.5, you'll find the Liberty Profile as a feature (As seen in the image). When installing WAS 8.5.5, you'll find the Liberty Profile as a separate installable package.
Click Next and finish the installation.
The Liberty Profile will be installed in WAS_INSTALL/wlp, eXtreme Scale will be installed in WAS_INSTALL\wlp\wx.
You are now ready to use your installation of WebSphere Liberty Profile and eXtreme Scale. You can download the airport sample to get started.
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.
The getting started samples are provided for a quick introduction to eXtreme Scale functionality and basic operation in an IIS environment, specifically running in Visual Studio.
The samples consist of an ASP based client application, including source, is provided to run simple create, read, update, and delete (CRUD) functions to this basic grid. The client application can also be used to run simple create, read, update and delete functions to a simple grid hosted on a WebSphere DataPower XC10 appliance.
Visual Studio 2010 or later Internet Information Services (IIS) for Windows® Server (usually comes with Visual Studio)
Before importing and running the sample application, you must perform a full installation of WebSphere eXtreme Scale to start a grid. You then will require to install the WebSphere eXtreme Scale Client for .NET.
Importing the sample into Visual Studio
You should now see the solution in your Solution Explorer. If there are build errors, then you must resolve them by adding the eXtreme Scale DLL files as References, as described in the following steps:
The correct references are now in the solution, you should be able to compile and build your solution.
Open Visual Studio
From the File menu, select Open, Project/Solution...
Browse to the directory of the downloaded sample, select IBM.WebSphere.caching.GettingStartedWeb.sln file, and click Okay.
Expand the GettingStartedWeb solution, and then expand References.
If IBM.WebSphere.Caching.dll is not resolved, you can remove it and add it where it is located on your machine.
Right click References, Add Reference....
Select the Browse tab. Look in the eXtreme Scale Client for .NET install/bin directory for IBM.WebSphere.Caching.dll and click Okay. You cannot have two of the same named references, so if you did not delete the one that came with the solution to add your new reference, please remove it first.
Running the client application
The client application is a simple ObjectGrid client that connects to a remote or embedded ObjectGrid and performs Create, Read, Update and Delete (CRUD) operations. This client can be used with a WebSphere eXtreme Scale grid or a simple grid on a WebSphere DataPower XC10 appliance.
After you have imported your solution file into Visual Studio, you can then build it and run the application on the IIS Server that comes with Visual Studio.
From the menu, select Build, Build Solution to compile.
Then to run the compiled code on the IIS Server, select Debug, Start Debugging.
In a browser, enter the following server URL: http://hostname:port
The <hostname> is the host name or IP address of IIS Server and <port> is the web server port for your IIS Server. See the following example:
In the Client Connection section, enter the hostname or IP address and port of the Remote catalog service endpoint in the form of hostname:port.
In the Grid name and Map name fields, enter the names of the target grid and map. The default for the Server servlet application provided is Grid for the grid name and Map1 for the map name. If you are using this client with an XC10 appliance, you must first create a simple grid on the XC10 appliance. Use the name of the simple grid for both the grid name and the map name.
After entering the catalog service endpoint, gridname, and mapname, click Connect to test the connection. If the connection is successful, you will see true for Client Connected.
Enter a string value for Key and a string value for Value. Then, select the appropriate CRUD operation; either Add, Replace, Remove, or Get.
Please post any feedback on this sample as a comment on this page.
The getting started with Continuous Query sample is provided for a quick introduction to the Continuous Query filtering. It consists of shell and batch scripts designed to start a simple grid with very little customization needed. The sample shows how to filter results automatically with WebSphere eXtreme Scale data grid.
Running the sample

Wait several seconds for the message: CWOBJ1001I: ObjectGrid Server cs0 is ready to process requests.
eXtreme Scale Usage Patterns
: A brief introduction to eXtreme Scale with a description of the four
basic usage patterns: 1. application state store (including HTTP Session
Management), 2. Side Cache, 3. In-line Cache (Database Shock Absorber),
4. Extreme Transaction Processing (XTP). Find out more here.
Elastic Caching with eXtreme Scale
: This video describes how eXtreme Scale provides grids that scale
elastically, meaning that they transparently scale out to add capacity
and scale in to recover from failures. Get more information here.
Episode 13 - Getting started with ADO.NET REST data service
ado dot net getting started tomcat demonstrates how to bring up the grid and bring up the data service framework using the getting started sample, then how to see what is happening in the grid. This first video uses tomcat and the second video uses the admin console. Download the sample from the main blog page.
These videos demonstrate how to set up an eXtreme Scale Data Service, and see it run with a web browser sample. Create a grid using the REST getting started steps, install and configure tomcat, and deploy the war file. The result is a working ADO.Net REST Data Service talking to an eXtreme Scale grid, ready to be a data service for any ADO.Net client applications.
