Abstract: The joint IBM and SAP development team introduced a new solution that further enhances the availability characteristics of one of the most business-critical components of an SAP system, the SAP enqueue server. There are two z/OS mechanisms for enqueue replication, the traditional TCP/IP replication server and the newly introduced SAP Enqueue Replication into System z Coupling Facility. The SAP enqueue server running on z/OS can now exploit the System z Coupling Facility (CF) as persistent storage for replication of its enqueue table.This paper will describe the performance of the new enqueue replication data in the Coupling Facility solution compared to standard TCP/IP based replication server. These tests were performed by the System z SAP Performance and Development teams at the IBM Systems & Technology Group Systems Solution Development Laboratory in Poughkeepsie, NY USA.
