Ultra Messaging Examples (UMExamples) is a documentation suite aimed at providing high quality educational samples for the Informatica Ultra Messaging (UM) product line. Every sample in the suite is coded ready to compile, though may not act as a great application as is. These examples are provided to instruct users of the UM API on how to use the API and best practices with regard to UM functionality. Along with each sample application is detailed documentation describing the purpose of the example, and walks through the sample code to provide clear instruction on how to best use Ultra Messaging.
In the list below, different examples are available in different source code languages (C, Java, C#/.NET), but this site is a work in progress, so many examples are not available in all laguages.
If you would like to see only those examples available in a particular language, you can visit:

UMExamples is created with SEMLIT
|mtools||C||Informatica "mtools" are a set of multicast test tools. Binaries and source code available for free.|
|cancelling_timers||C Java C#/.NET||Example on how a context can schedule and safely cancel timer callbacks|
|check_flight_size_ewouldblock||C Java C#/.NET||A send can fail with an EWOULDBLOCK error, which can have different root causes. One cause for a persisted source is exceeding flight size. This example shows how to determine if flight size is the cause of an EWOULDBLOCK error.|
