A DTX participant is an internal memory structure that the coordination service uses to manage a remote transaction branch. As transactions are propagated to remote servers, the coordination service must obtain new DTX participants to manage those branches.
Setting number of dtx participants to a number smaller than the default reduces the number of remote transactions that the server can manage. If no DTX participants are available, new distributed transactions cannot start. In-progress distributed transactions may abort if no DTX participants are available to propagate a new remote transaction.
Setting number of dtx participants to a number larger than the default increases the number of remote transaction branches that SAP ASE can handle, but also consumes more memory.
