BRARCHIVE function

BRARCHIVE is an SAP tool for managing data in the Oracle database. It is used to back up offline redo log files. To save each redo log file to Tivoli® Storage Manager, BRARCHIVE calls Data Protection for SAP either through the BACKINT interface or through RMAN.

BRARCHIVE maintains a list of redo logs to be saved. Redo logs that were successfully saved by Data Protection for SAP might be deleted from the file system immediately by BRARCHIVE. However,

BRARCHIVE deletes redo log files only in the order of the list. If the requested number of backup copies cannot be saved for a redo log, this redo log and all subsequent redo logs are maintained. When BRARCHIVE starts again, these redo logs are saved again even if some are successfully saved earlier.

Data Protection for SAP informs BRARCHIVE about the redo logs that were saved successfully to Tivoli Storage Manager. If a problem occurs, Data Protection for SAP makes several attempts to save the redo log.

When a redo log cannot be saved to the number of copies that are requested, Data Protection for SAP ends with an error. Data Protection for SAP does not try to save redo logs with a higher sequence number because they are saved in a later BRARCHIVE run.
