MVSSERV command

Use the MVSSERV command to start a session between an IBM® Personal Computer (PC) and an IBM host computer running TSO/E on MVS™. The is a set of programs that allows a PC user to request services from a host program. The PC requesting program is referred to as the requester. The host program that executes the corresponding service is referred to as the server. For more information about IBM-supplied servers that you can use, see Introduction to IBM System/370 to IBM Personal Computer Enhanced Connectivity Facilities.

By using the operands on the MVSSERV command, you can accumulate all, some, or no diagnostic information in a trace data set. The diagnostic information includes the following:

Informational and error messages
An execution path table that tracks module calls
Requests and replies sent between the PC and the host

However, before using MVSSERV, you must have certain pre-allocated data sets. Your installation may have already pre-allocated those data sets for you. They are described in z/OS TSO/E Guide to SRPI. The guide also describes how to write and install servers.

Note: MVSSERV is not supported under z/OSMF ISPF.
