Databases The following database are used in DataMgr:
• BFS Database on the BFS component.
• Managed File System Database on each client.
• Client Transaction Database on each client.
Both the BFS Database and the Managed File System Database
must be sized.
Size BFS
Database The BFS Database is located under /etc/dm/raima/bfs .
This Database contains the bitfile IDs for migrated files. A
bitfile ID points to a specific RID (record ID) on AMASS. This
is how DataMgr keeps track of where client files have been
migrated.
Use the formula below to determine the space required for the
BFS Database:
