Applying Message Transformations at the Integration Gateway
Typically, you apply filtering, transformation, and data translation to a message at the node level on the application server by using a transaction modifier to invoke an Application Engine transform program. However, on systems with high transaction volumes, Application Engine transformations can constrict message throughput. To improve performance, you can apply XSLT transformation programs at an integration gateway.
Note:
While you may apply transformations at the integration gateway level, PeopleSoft strongly recommends that you apply them at the application server level due to a more robust infrastructure to support them.
