WebSphere® eXtreme Scale: Store mediation primitive properties

You can specify values for mediation primitive properties either by using the property fields in the IBM® Integration Designer user interface or by using an XML format. The property field names displayed in IBM Integration Designer are generally different from the property names used when building a mediation flow using XML code. In the following information, icons are used to identify each property name used in IBM Integration Designer and the corresponding XML name. (Where applicable, XML names that are required, but not shown in IBM Integration Designer, are also described.)

eXtreme Scale definition cacheName

The name of the eXtreme Scale definition used to store data. The maximum length is 256 characters. If this definition is not set, the default eXtreme Scale definition as defined in the AdminConfig of the server is used. This definition can be set in the runtime administrative console or by using admin commands.
