Project: Mainframe to Distributed System Interface
Location: Sprint Long Distance
Platform: Windows NT; 3270
Tools: COBOL II; TCP/IP
Worked with a small team to develop and implement a interface between a legacy mainframe system and a distributed management system. COBOL II was used to implement the report generation process on the mainframe side, while a TCP/IP link was built to
supply the distributed system with appropriate data. A guaranteed delivery system was also needed, which would insure the delivery of the data between the points which where not
directly involved in the TCP/IP connection.
