Capture for MVS provides you with the following tools to assist you if a severe error occurs:
The following sections provide information on these tools.
If a severe error occurs, Capture for MVS alerts NetView if NetView is active. The alert uses the NMVT format for a generic alert defined by the SNA generic alert architecture. If NetView is unavailable, diagnostic information is still available because Capture for MVS error messages are sent to the MVS console.
Capture for MVS puts a small amount of critical diagnostic data in a wraparound trace buffer during processing. Each trace buffer entry describes current data capture status. If a severe error occurs, Capture prints the trace buffer before termination. The printing of the trace buffer supplements the Capture program error message.
When an error occurs, you can run the Capture program with the TRACE option. When you use this option, IBM replication writes trace information logic flow to STDOUT.
When Capture for MVS terminates with a severe error, it saves critical diagnostic data in the CEEDUMP data set. This information is more detailed than the information in the Capture program trace buffer.
