    Guide to Index Corruption Recovery This procedure describes a methodology for recognizing and recovering from index file corruption which may be experienced with the BMC II BISYNC system. Index file corruption can occur for a variety of reasons. This procedure neither catalogs nor explains all those reasons; rather, it offers practical advice for identifying and correcting certain types of index file corruption should it occur.
