Architecture Overview
administrative command, set MXCI to the MXCS mode as described in MXCI Mode
Command on page 2-12.
An operational MXCS association server is not required for data source and
environmental variable configuration commands, but must exit (stopped state is OK)
when you want to query the current status of the service, data source, or servers
running in that service.
In Figure 1-1, assume that the MXCS facility is started. The normal flow for MXCS
administrative command processing is:
1. MXCI starts and accepts a command from a terminal or disk file.
2. The MXCI command manager has been set to the MXCS mode so it passes the
command to the MACL routines.
3. MACL parses the command and requests the client library perform the action.
4. The client library transmits requests to the appropriate MXCS component and
returns responses.
5. MACL formats the responses into reports.
6. MACL returns status to the MXCI command manager.
7. The MXCI command manager displays all result and error lines and then waits for
further input.
