Overview of Transaction Coordination Services

SAP ASE provides services to propagate transactions to remote servers and coordinate the work of all servers, ensuring that all work is either committed or rolled back as a logical unit.

With these transaction coordination services, SAP ASE itself can act as a distributed transaction manager for transactions that update data in multiple SAP ASEs.

• Hierarchical Transaction Coordination
  Because other servers involved in a distributed transaction may also coordinate remote participants, transactions can be further propagated to additional servers in a hierarchical manner.
• X/Open XA-Compliant Behavior in DTP Environments
  The X/Open XA protocol requires resource managers to provide coordination services for transactions that are propagated to remote resource managers.
