Consider the following rules and guidelines when you configure a JMS mapping:
•You can only use certain transformations when you run a JMS mapping. For more information on the transformations that you can use, see the Custom and other active transformations knowledge article.
•To run a data preview job for a mapping, click Run Preview on the Preview panel in the Mapping Designer.
•You can configure a commit interval in the Advanced Session Properties on the Runtime Options tab of the mapping task:
Session Property Name
Session Property Value
Commit Interval
10
Ensure that the commit interval is lesser than the DTM buffer size. When you do not configure a commit interval, the mapping uses the default DTM buffer size.
