The VCOM Client is an implementation of a distributed VCOM API running on a machine that doesn’t necessarily have a VCOM node itself. The client connects to a VCOM node and communicates with an API server on that machine using the VCOM Client/Server protocol over any supported network connection. The computer running the client is usually a PC or a UNIX workstation, however VCOM Clients are also available for VSE/ESA mainframe environments and VCOM Java Clients run on any platform with a Java Virtual Machine.
The VCOM Client offers the same functionality (the CS and DS services) as the local VCOM API. VCOM Clients can choose which VCOM node to connect to (a feature not currently available in the local VCOM API).
