Start CICS and MSO. Check their log files to ensure normal startup.
Run the MSO transaction. You should get message MSO13239, followed by the FOCUS Terminal Operator Environment Screen. Message MSO13029 should appear in the MSO log.
Run a few commands in FOCUS to ensure the session is behaving properly, and then issue FIN to end the session.
Verify that the message 13028 appears in the MSO log and that MSO13300 appears on your CICS terminal.
Run MSO again, to ensure communication restarts properly.
Run MSO from a second terminal, to ensure multiple sessions can be run concurrently.
Run MSMT.
Bring down CICS and MSO; to ensure both can come down without any problem.
