Abstract

The Transmission Control Protocol/Internet Protocol (TCP/IP) solution disclosed here allows for multiple TCP/IP client connections to an MVS/ESA* Multiclient Remote Environment Server (MRES). This enables remote client applications to run transactions with no noticable performance degradation and benefit from the MVS address spaces saved by using a Multiclient server.

Transmission Control Protocol/Internet Protocol for the MVS Multiclient
Server

      The Transmission Control Protocol/Internet Protocol (TCP/IP)
solution disclosed here allows for multiple TCP/IP client connections
to an MVS/ESA* Multiclient Remote Environment Server (MRES).  This
enables remote client applications to run transactions with no
noticable performance degradation and benefit from the MVS address
spaces saved by using a Multiclient server.

      To maintain a high quality connection for remote client
applications, this TCP/IP MRES solution uses:
  o  TCP socket calls to accept and concurrently process data from
      remote clients.
  o  Communication parameters which are controlled by the MVS
      operator.

The TCP/IP MRES is started as a catalogued procedure by an MVS
operator.  These parameters control TCP/IP client connections:
  UPN=n           A parameter that specifies the unique port number
                   used to communicate between TCP and the MRES
address
                   space.
  IPA=n.n.n.n     A parameter that specifies the IP address used to
                   access the MRES address space.
  ASN=id          A parameter that specifies the name of the TCP/IP
                   address space.
