Checking the consistency of the database

A consistent database is the most important prerequisite for successful restructuring. The BCHECK utility routine should be used to ascertain the consistency of the database (see the "Recovery, Information and Reorganization" manual).

If BCHECK detects any inconsistencies, the database should on no account be restructured before it has been recovered, otherwise errors may be compounded and this will make recovery of the inconsistent database even more difficult.
