Version 2.5 includes
support for enterprise data grids, .NET applications, security enhancements,
continuous query, monitoring improvements, and near-cache invalidation.
support.
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...
Appliance startup status
You can now view the startup status of the appliance in the user
interface.
Learn more...
ASP.NET session state store
provider
You can configure your ASP.NET applications to store
session state in the data grid.
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...
Delete tasks
You
can delete all tasks in the user interface.
Learn more...
Dynamically update client
properties for .NET
You can configure
WebSphere eXtreme Scale Client for .NET to dynamically
pick up manual modifications that are made the property values in
client properties files. You do not need to restart the existing connection
to the data grid for the changes to take effect.
Learn more...
Enable FIPS
You can
configure the appliance collective to use Federal Information Processing
Standard (FIPS) 140-2 for all encrypted network communication. This
standard ensures high protection of data as it is sent over the wire.
Learn
more...
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...
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...
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).
Getting started sample
You can use the getting started sample to run Java and .NET client
applications that access the data grids on your appliance.
Learn more...
Grid alias
You can
use the REST gateway to create and manage a grid alias. Use a grid
alias when you need to populate more than one grid at the same time.
Learn more...
Host name management
With the
publishHost property, you can configure
and override the host name that is published. Using this property
allows more fine-grained control over the communication that flows
between clients and servers, which gives you the ability to optimize
communication between nodes in the data grid.
Learn more...
LDAP over SSL
Secure
your Lightweight Directory Access Protocol (LDAP) directory to authenticate
users that access your appliance. To secure this the LDAP directory,
configure the appliance to authenticate to LDAP over an SSL connection.
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.

New xscmd utility commands and parameters
- xscmd -c getNotificationFilter command: Run
this command to display the current filters for new notifications
from the message center. Learn more...
- xscmd -c listenForNotifications command: Run
this command to listen for new notifications from the message center. Learn
more...
- xscmd -c setNotificationFilter command: Run
this command to create a filter for new notifications from the message
center. Learn more...
- xscmd -c showLinkedDomains command: Run this
command to check which catalog service domains are linked to your
local catalog service domain. Learn more...
- xscmd -c showNotificationHistory command: Run
this command to display the output of the event notification history
in tabular format.
- xscmd -c showSessionSize command: Run this
command to display the size of a specified session. Learn more...
- -to or --timeout parameter:
Specify this parameter to reduce the timeout value to avoid waiting
for operating system or other network timeouts during a network brown
out or system loss. Learn more...
- -hc or --linkHealthCheck parameter: Use this parameter with the xscmd -c showLinkedPrimaries command to verify that the primary shards have the appropriate number
of collective links.
- xscmd -c listDisabledForPlacement command:
Run this command to display a list of shard containers that have been
disabled for shard placement.
- xscmd -c listIndoubts command: Run this command
to display a list of in-doubt transactions. Run this command when
you want to resolve possible lock timeout exceptions on a partition. Learn more...
- xscmd -c showReplicationState and xscmd -c showDomainReplicationState commands: Run these
commands to see the state of the revisions across your catalog servers
or catalog service domains. Learn more...
- xscmd -c showTransport command: Run these commands
to display the transport type of the catalog service domain. Learn
more...
Override the requestRetryTimeout property in dynamic cache data grids
Use the
com.ibm.websphere.xs.dynacache.request_retry_timeout_override dynamic cache property to override the
requestRetryTimeout property in the client properties file, and specify how long, in
milliseconds, a request can run before timing out.
Learn more...
Run the xscmd utility from within the appliance command-line interface
You can run the
xscmd utility from within the
appliance command-line interface. When you invoke the utility from
within the appliance command-line interface, providing command-line
arguments for security and catalog server connections are not required.
Learn more...
Secret key generation
Override the factory default authentication secret key to specify
a unique secret key in the web console.

Updated Simple Network Monitoring
Protocol (SNMP) statistics
The management information bases
(MIBs) provided on the
WebSphere DataPower XC10 Appliance to specify the SNMP data available to the SNMP client is now
updated with new statistics. New statistics include applianceUsedBytes,
applianceCapacity, gridUsedBytes, and gridCapacity. For more information
on how to enable SNMP monitoring and download this MIB file, see
Enabling SNMP monitoring for your appliance.
Specify timeout and request
timeout values
You can specify the amount of time that a connection
or request is processed, whether you use the eXtremeIO (XIO) transport
or the Object Request Broker transport. For example, in XIO you can
use the property,
xiotimeout, to specify the
timeout value for outbound socket connection attempts, and you can
use the
xioRequestTimeout property to specify
the number of seconds that any request waits before it times out.
The
requestRetryTimeout property can be applied
to either the XIO transport or the ORB transport. Use this property
to specify how long to continue processing a request after an exception
occurs.
