Editing a Mediation Sequence

The "main" and "fault" sequences are created and preconfigured automatically while installing ESB. You can adapt existing sequences for your needs. 

You can change the sequence properties and its mediators in UI or using XML. When you are editing a sequence, the name of the sequence should not be edited and changes to the sequence name will not be effective.
