For information see the section Using UM API libraries for .NET in .NET Standard projects in the Developer Guide.

Support for deleting clusters using the Tools Runner application

The Tools Runner application (runUMTool) has been extended with a new command DeleteCluster. This command allows you to delete an existing cluster.

Changed features in v10.4

The following Universal Messaging features already available in the previous product release have been changed in Universal Messaging 10.4:

Multiplex session authentication

There is a change in the way user names are handled for client authentication in a multiplex session.

For details, refer to the topic Multiplex session authentication in the section Multiplexing Sessions in the Concepts guide.

Horizontal Scalability

Universal Messaging sessions using the "horizontal scalability" feature now support automatic (re-)connection to realm servers in the scalability set that are offline/unavailable when the session is created or initialized.

Also, HS sessions support connecting to various connection interfaces, e.g. NHP/NHPS/NSP/NSPS, and you can use a combination of these in a single HS RNAME.

For details, refer to the topic Usage Notes for Horizontal Scalability in the section Horizontal Scalability in the Concepts guide.

Updated System.Reactive Libraries for .Net Reactive samples

The .Net Reactive Extensions (Rx) sample programs have been updated to use System.Reactive libraries v3.1.1. In the previous product release, version 1.0 of these libraries was used.

The sample programs are located under in folder <InstallDir>\UniversalMessaging\docnet\examples.

Using AMQP in clustered environments

Universal Messaging now supports AMQP 1.0 in clustered environments.

At the moment, automatic failover of AMQP clients is not supported. If the AMQP connection fails it is the responsibility of the AMQP client application to reconnect to another node in the cluster.

Note:
For the initial release of V10.4, the new functionality is provided as a software fix that you need to install after the standard product installation procedure has completed. To install the fix, you can use either Command Central or the Software AG Update Manager. If you wish to use the Update Manager, general instructions are provided in the document Using Software AG Update Manager that you can find on the Software AG documentation web site.
