The Administrator’s Interface provides the following capabilities:
Data Archive - Archive batch data to a specified archive database.
Data Deletion - Delete archived data from the primary storage database.
Data Restore - Restore archived data availability through the primary storage database.
Data Storage - View the location, size, and usage order of the storage databases. These are user configured values and are defined as part of the Batch Historian properties in DeltaV Explorer. Errors related to data storage are displayed in the Administrator's Interface status bar.
The DeltaV Batch Historian stops recording when it reaches 97% of the space allocated. 3% of the space is always reserved for administrative overhead. When the total database usage exceeds 80% of the allocated size of all the output databases combined, DeltaV Diagnostics shows the Batch Historian subsystem's overall integrity as Bad. The status bar lists the name of the database that is full and also reflects the server's status. The Batch Executive will continue to generate events and buffer them to the Batch Historian's database in an .evt file.
Data Statistics - View the total number of messages received, the number of messages stored, the number that were unrecognizable (but still stored), and the number that could not be stored. Collection statistics are categorized by total messages, batch message, and event messages.
Duplicate messages report that the historian is reading some data multiple times. This can occur if a batch evt file is taken out of the journals directory and then put back into the journals directory. Duplicate messages are not stored a second time.
Unidentified messages report that the Batch Historian is reading messages for which it has not been programmed to process. Such messages include user created alarm types since the Batch Historian can not have a definition for them. The unidentified messages are stored in the UnhandledBatchMsg and UnhandledEventMsg to enable troubleshooting. The events are also reported in the batcheventview and eventoverview but are identified as unhandled to provide visibility to the event.
Server Status - View current information about the configured servers, including server type, server node name, and connection status.
Source Linkage - Link batch equipment to control equipment to enable continuous process history events and alarm data to be included in batch reports.
