Invalidating Sessions

Invalidating Sessions

When you edit and save a mapping, some changes cause the session to be invalid even though the mapping remains valid. The Integration Service does not run invalid sessions. If you edit a mapping, the Designer invalidates sessions when you perform the following actions:
  • Add or remove sources or targets.
  • Remove mapplets or transformations.
  • Replace a source, target, mapplet, or transformation when importing or copying objects.
  • Add or remove Source Qualifiers or COBOL Normalizers, or change the list of associated sources for these transformations.
  • Add or remove a Joiner or Update Strategy transformation.
  • Add or remove transformations from a mapplet in the mapping.
  • Change the database type for a source or target.
