Historical Server reports errors in the monitoring data output saving process in the same manner as it does when outputting to flat files. You are notified of the errors encountered through the session error files and the HS log file. Errors relating to the database output mode can include:
If the target Adaptive Server does not exist, Historical Server reports a failure.
If the target database specified on the command-line does not exist, Historical Server reports a failure.
If Historical Server cannot write to the database specified on the commandline because it has run out of disk space, Historical Server reports a failure.
If Historical Server has to add columns to an existing table in order to use it for its monitoring output, it will log a warning message.
