ABSTRACT:
A method for processing distributed application programs in SNA type networks employing LU 6.2 protocols, including an information processing system having a host processor, a virtual machine type Operating System, and a plurality of Intelligent Work Stations (IWSs). The Operating System is provided with a Virtual Machine Pool Manager (VMPM). The function of the VMPM is to create and dynamically manage the assignment of a plurality of virtual machines in the pool to process requested individual LU 6.2 conversations, to permit the transfer of information between Parts A and B of a distributed Application, which parts are stored respectively at one IWS and the host processor. In response to a conversation request, an idle Virtual Machine (VM) in the pool is assigned by the VMPM to process one LU 6.2 conversation. At the termination of the conversation the VMPM returns the assigned VM to the pool with an idle status so that it can be assigned to process another conversation requested by the same IWS or a different IWS. An LU 6.2 "session" between Part A of a DAP executing on one IWS and Part B executing on the Host Processor, involving a plurality of sequential conversations spaced apart in time, involves only the assignment of VM resources from the pool at the host for the actual conversation time of the "session", and not the total session time. As a result, VM resources at the host can service a larger number of IWSs.
