Microsoft Host Integration Server
Microsoft Host Integration Server is a gateway application providing connectivity between Microsoft Windows networks and IBM mainframe and AS/400 systems. Support is provided for SNA, 3270, 5250, CICS, APPC, and other IBM protocols. Support is also provided for advanced integration with Windows networks and software, such as linking Microsoft Message Queuing applications to IBM WebSphere MQ, binding Microsoft DTC transactions with CICS, and cross-protocol access to DB2 databases on IBM platforms.
HIS is the successor to Microsoft SNA Server. SNA Server was released in 1994, and was one of the first add-on products available for the fledgling Windows NT.
Similar gateway products are NetWare for SAA and IBM Communications Manager/2.
HIS has an active ecosystem of third party hardware and software.
