Metacat

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

#will record the performance data into a file. Since we need restart postgres,

#this script should be run as root user

#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.
