[Version 8.6.0.2 and later]

ASP.NET session state store provider

You can configure your ASP.NET applications to store session state in the data grid. Learn more....
[Version 8.6.0.2 and later]

Encode the credentialGeneratorProps property in client properties files for .NET

You can encode the value of the credentialGeneratorProps property in the Client.Net.properties file with the FilePasswordEncoder utility. Learn more...

Continuous query

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 continuous query to be notified in your client Java virtual machine (JVM) when data is inserted or updated in the data grid. This feature makes grid and data management easier for developers, administrators or both. Learn more...

Disk overflow

You can use disk overflow to extend the data grid capacity by moving cache entries out of memory and into disk. When you enable disk overflow, entries that do not fit into the available memory capacity of the container servers are stored on disk. Learn more...

Display values of queried data

You can now display values of the keys in data queries that you create in the monitoring console or with the xscmd utility. Learn more...

Enterprise data grid

Enterprise data grids use the eXtremeIO transport mechanism and a new serialization format. With the new transport and serialization format, you can connect both Java and .NET clients to the same data grid.Learn more...

Global index

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 environment. Learn more...

Global index invalidation

You can optionally enable global index invalidation to improve invalidation efficiency in a large, partitioned environment; for example, more than 40 partitions. Learn more...

High Performance Extensible Logging (HPEL)

You can enable catalog and container server to use HPEL, an alternative to the basic log and trace facility. Learn more...

IBM Support Assistant Data Collector

The IBM® Support Assistant Data Collector is a tool you can run to gather data from your WebSphere eXtreme Scale environment for problem determination purposes. Learn more...

Inverse range index

You can configure an inverse range index using the built-in InverseRangeIndex plug-in. Learn more...

List of shard containers that are disabled for placement

When a problem occurs with placing shards on a particular shard container, the shard container is placed in a list that disables that shard container from receiving further placement requests. You can list the disabled shard containers and remove a shard container from the list with xscmd commands. Learn more...

Message center

The message center provides an aggregated view of event notifications for log and first-failure data capture (FFDC) messages. You can view these event notifications with the message center in the web console, the xscmd utility, or programmatically with MBeans. Learn more...

Multi-partition transactions

WebSphere eXtreme Scale Client now supports transaction updates to multiple partitions in a data grid. Learn more...

Near-cache invalidation

You can configure near cache invalidation to remove stale data from the near cache as quickly as possible. When an update, deletion, or invalidation operation is run against the remote data grid, an asynchronous invalidation gets triggered in the near cache. Learn more...

WebSphere eXtreme Scale Client for .NET

By installing the WebSphere eXtreme Scale Client for .NET, you can deploy .NET applications that access the data grid. Learn more...

New methods and APIs

New xscmd utility commands and parameters

Remote logging

You can enable remote logging to save log entries on a remote server. You must have a syslog server available to listen for and capture events. Learn more...

REST gateway support

You can use the Representational State Transfer (REST) gateway to access simple data grids that are hosted by a collective. This REST gateway is useful when you must access grid data from non-Java environments. Learn more...

Support for Java Servlets 3.0 Specification

WebSphere eXtreme Scale HTTP session management function now supports Java Servlets 3.0 specification. When you are writing applications for WebSphere eXtreme Scale in a stand-alone environment, only listeners specified explicitly in the web.xml are called back when sessions are invalidated using remote WebSphere eXtreme Scale container eviction.

eXtreme Data Format (XDF)

XDF is based on the MapSerializerPlugin plug-in, and is now the default serialization technology that is used when you are running IBM eXtremeIO (XIO) and have your map copy mode that is set to COPY_TO_BYTES. When you enable this feature, Java and C# objects can share data in the same data grid. Learn more...

WebApp feature

The Liberty profile webApp feature contains the capability to extend the Liberty profile web application. Add the webApp feature when you want to replicate HTTP session data for fault tolerance. Learn more...

WebGrid feature

With this Liberty profile feature, aLiberty profile server can host a data grid that caches data for applications to replicate HTTP session data for fault tolerance. Learn more...
