Choose the event format
This topic shows you how to choose between the two event formats available in IBM Integration Designer.
Events in IBM Integration Designer can be of two types:
- 6.1, 6.2, and 7.0 format
- 6.0.2 format
The 6.1, 6.2, and 7.0 format event contains the payload as an XML element into the xsd:any slot of a common base event. Since the payload is stored in the xsd:any slot, you can get it back as an XML instance and use existing XML technologies to process it in an efficient way. In a 6.0.2 format event the business payload data is shredded or serialized as a hexadecimal value into the common base event extended data elements.
Mediation modules
For mediation flows, you must explicitly choose the 6.0.2 format if you want to emit 6.0.2 style events. In short, the version of events emitted from mediation flow emitters is dependent on the properties selected in the Global Event Settings page of the Event Monitor tab in the assembly editor. (To open this tab, you select the mediation flow in the assembly editor and click the Properties > Details tab, then expand the interfaces in the Details page and select your operation.) If you have selected the 6.0.2 event format, then this event format is read and used at run time. If you have not selected the 6.0.2 event format, then the 6.1, 6.2, and 7.0 format is used by default for the mediation flow.
Depending on whether you previously selected SCA events for a 6.0.2 mediation module that you now want to import into IBM Integration Designer, the mediation module will exhibit one of the following two behaviors:
- If you previously selected SCA events for the 6.0.2 mediation module in the General page of the Event Monitor tab, then all of the events will be emitted in 6.0.2 format.
- If you did not previously select SCA events for the 6.0.2 mediation module in the General page of the Event Monitor tab, then all of the events will be emitted in the default 6.1, 6.2, and 7.0 format.
As stated earlier, you can change the event format in the Global Event Settings page of the Event Monitor tab. (If that the Legacy hexBinary selection is not applicable for mediations.)
