Network system
First Claim
1. A network system comprising:
- a wide area network;
a plurality of target servers as objects for monitoring and connected to said wide area network;
a plurality of terminals connected to said wide area network for accessing and monitoring performance of said target servers; and
a test server connected to said wide area network for transmitting, to said terminals, commands for testing said target servers, wherein;
said test server comprises;
command transmitting means for transmitting a data base access command signal including a data base access command execution time and a data base access command, to said terminals,performance evaluation data receiving means for receiving performance evaluation data for said target servers, transmitted from said terminals, andfirst performance evaluation data storage means for storing the received performance evaluation data;
each of said terminals comprises;
command receiving means for receiving the data base access command signal transmitted from said test server,command storage means for storing the received data base access command signal,access executing means for reading the data base access command from said command storage means according to a data base access command execution time in the data base access command signal and for transmitting the data base access command to said target servers and accessing said target servers at the data base access command execution time,access result receiving means for receiving a result of access corresponding to the data base access command transmitted from said target servers,response time measuring means for measuring a response time of said target servers from transmission of the data base access command to said target servers until time when a reception of results of access transmitted from said target servers,second performance evaluation data storage means for storing performance evaluation data including a result of access received by said access result receiving means and a response time measured by said response time measuring means,command execution end determining means for determining whether all data base access commands have been executed, andperformance evaluation data transmitting means for reading the performance evaluation data from said second performance data storage means and transmitting the performance evaluation data to said test server when all data base access commands from all of said terminals have been executed by said target servers and all of the performance evaluation data has been received by said terminals; and
each of said target servers includes an access result transmitting means for transmitting a result of access corresponding to the data base access command transmitted from said terminals to each of said terminals.

Abstract
A network system temporarily stores all data base access commands transmitted from a test server in a command storage section, is in the stand-by state until a data base access command execution time written in one of the data base access commands comes, and reads out the data base access command from the command storage section, when the data base access command execution time has come, for accessing data base servers 1a to 1n, and also the network system temporarily stores all performance evaluation data for the data base servers 1a to 1n in a performance evaluation data storage section, reads out performance evaluation data from the performance evaluation data storage section when it is determined that execution of all data base access commands has been finished, and transmits the read-out data to the test server.
