Guidelines for using Transaction Control transformations in mappings

Guidelines for using Transaction Control transformations in mappings

Consider the following guidelines when you use a Transaction Control transformation in a mapping:
  • Incoming data must be sorted by the fields that you use in the transaction condition. Place a Sorter transformation upstream of the Transaction Control transformation or use a sorted data source.
  • Configuring the transaction control condition to perform frequent commits can affect performance.
  • If the mapping includes an XML target, and you choose to append or create a new document on commit, the input groups must receive data from the same transaction control point.
  • Transaction Control transformations that are connected to any target that does not support batch or transaction real-time processing are ineffective for those targets.
  • You must connect each target instance to a Transaction Control transformation.
  • You can connect multiple targets to the same Transaction Control transformation.
  • You can connect only one effective Transaction Control transformation to a target.
  • You cannot place a Transaction Control transformation in a pipeline branch that starts with a Sequence Generator transformation.
  • If you use a dynamic Lookup transformation and a Transaction Control transformation in the same mapping, a rolled-back transaction might result in unsynchronized target data.
  • Either all targets or no targets in the mapping should be connected to an effective Transaction Control transformation.
