For each mainframe LPAR to be discovered there is one service created. This service runs the Ironstream Message and Command Server service (MCS) which maintains an active connection with the Ironstream mainframe agent.
The ev390hostcmd utility program is the vehicle for sending data requests to the Ironstream mainframe agent and receiving responses to those requests. This program may be executed directly by discovery probes or by scripts which are executed by discovery probes.
You must install these Ironstream Proxy Server components before you install the Ironstream agent.
