MSIR.0301 Using disk buffer monitor
This warning message indicates that Fast/Reload has determined that it cannot use full track I/O to write the table B pages for the database file and instead must go through the Model 204 disk buffer monitor. This may be a result of the user specifying the DKONLY option, loading into a pre-release 8 file, loading into an already populated hash or sort key file or some other problem. When operating in this mode, Fast/Reload will tend to work more slowly than when using full track I/O. If performance is a critical concern, you should determine why Fast/Reload is not using full track I/O and correct the problem.
