Description:

3011W Time out waiting for system command response

Explanation:
A Cybermation product issued a system command and timed out waiting for a system command. This may happen if the system is congested.

System Action:
Processing continues.

User Response:
Normally none.
If the problem is persists and it does not appear to be due to system congestion, call Cybermation support.

Solution:

When ESP handles VS command, it turns on a 10 sec timer, and if there is no response within 10 sec, it issues 3011W message.

Note: With USERMOD 57 set, no responses will be sent to the event owner; the command will still be sent to z/OS for execution.
