As a server, the importance of the MFA Server address space should be set below TCPIP but above the Data Connect Mainframe Access Server, and other Mainframe Access Application Servers such as Endevor, Changeman, IDCAMS, and MFATSO Application Servers. This setting is checked when MFA Server starts up, terminates, or when commands are executed against the MFA Server address space.
The user servers should be classified like any TSO user address space, using the response time goal of TSO. All transactions executing within the user server are TSO transactions.
