The mainframe as a high-available, highly scalable CORBA platform

The increasing demand for interoperable systems requires the integration of traditional mainframe-based transaction processing (TP) monitors with CORBA-based middleware infrastructures. We discuss various integration approaches. The integration of IBM's IMS-TM (Information Management System Transaction Manager) and CORBA is discussed in detail, and up-to-date performance and scalability results are presented. The results show that the combination of CORBA and mainframe-based TP monitors is significant step towards highly available, highly scalable object transaction monitors (OTMs).
