DDM listener restriction
Only one DDM listener can be active at one time. Requests to start the listener when it is already active will result in an informational message to the command issuer.
The DDM server will not start if the QUSER password has expired. IBM recommends that the password expiration interval be set to *NOMAX for the QUSER profile. With this value the password will not expire.
