Metacat

#!/bin/bash

#Call a java client class to query metacat automatically and metacat server

#will record the performance data into a file.  This script will be put in /etc/init.d directory

#and called in system booting. After script is down, it will call reboot system too.

#So every time to excecute the quyer, memory will be in fresh.

#Note: before running the script, user should run both "ant jar" and "ant clientjar"

#in Metacat to get metaca-client.jar and metacat.jar in build directory.
