Bufserv and PIBufss

It is undesirable to write shutdown events when buffering is being used. Bufserv and PIBufss are utility programs that provide the capability to store and forward events to a Data Archive, allowing continuous data collection when the Data Archive is down for maintenance, upgrades, backups, and unexpected failures. That is, when the Data Archive is shutdown, Bufserv or PIBufss will continue to collect data for the interface, making it undesirable to write SHUTDOWN events to the PI points for this interface. Disabling Shutdown is recommended when sending data to a Highly Available Data Archive collective. Refer to the Bufserv or PIBufss manuals for additional information.
