The following commands must be installed and enabled on the UNIX machine:
RExec - Used to drive the monitor.
Note: The server must be running Rexecd in order to use this utility. In addition, some variants of UNIX may handle an rexec as an rlogin. These may automatically execute login files such as ".profile". In this case, extraneous output commands such as echoing "motd" (message of the day) may interfere with Toad's parsing of the output.
lostat - Used to get the disk io information.
vmstat - Used to obtain cpu information
ps - Used to process queues and lists.
