The Fileset Location Database (FLDB) is maintained by the Fileset Location Server (FL Server). A master copy of the FLDB is stored on one Fileset Database machine, with copies synchronized on other Fileset Database machines via the Ubik library of facilities. It is essential that the information in the FLDB correspond to the status of the filesets on the File Server machines. Therefore, any fts command that affects fileset status also changes the corresponding FLDB entry automatically. If an fts operation is interrupted before completion, information in the FLDB can differ from information on a File Server machine. In these cases, the fts syncfldb and fts syncserv commands must be used to align the information.
There is an entry in the FLDB for each read/write DCE LFS and non-LFS fileset. Each entry for a DCE LFS fileset also records information about the read-only and backup versions of the fileset, because these versions do not have their own entries. The information in an FLDB entry includes the fileset's name and fileset ID number, the ID numbers of its read-only and backup versions (if it is a DCE LFS fileset), site definitions, site counts, and status flags. Complete details about the FLDB are included in Part 1 of the OSF DCE DFS Administration Guide and Reference.
