The default action taken by the Message Agent when an error occurs is to record the fact in its log output. The Message Agent sends log output to a window or a log file recording its operation. By default, log output is sent to the window only; the -o option sends output to a log file as well.
The Message Agent may print more information in the output log than in the window. The Message Agent log includes the following:
Listing of messages applied.
Listing of failed SQL statements.
Listing of other errors.
UPDATE conflicts are not errors, and so are not reported in the Message Agent output.
For more information on the log file, see Message Agent.
