Overview

The example has a single PVRecord:

mydevice
structure 
    double x
    double y
    time_t timeStamp

The record has channelRPC support that implements a series of moves. Each move sets new values for x and y. A delay occures between each move.

Start Service

mrk> pwd
/home/epicsv4/master/exampleJava/pvDatabaseRPC/shell
mrk> ./exampleRPCMain

Start Client

mrk> pwd
/home/epicsv4/master/exampleJava/pvDatabaseRPC/shell
mrk> ./move 10 20 30 40

This example will result in two moves. The first will move to x=10 and y=20. The second will move to x=30 and y=40. As many moves as desired can be specified but an even number of arguments must be given.
