db_verify [-NoqV] [-h home] [-P password] file ...  

The db_verify utility verifies the structure of one or more files and the databases they contain.

The options are as follows:

The db_verify utility does not perform any locking, even in Berkeley DB environments that are configured with a locking subsystem. As such, it should only be used on files that are not being modified by another thread of control.

The db_verify utility may be used with a Berkeley DB environment (as described for the -h option, the environment variable DB_HOME, or because the utility was run in a directory containing a Berkeley DB environment). In order to avoid environment corruption when using a Berkeley DB environment, db_verify should always be given the chance to detach from the environment and exit gracefully. To cause db_verify to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).

The db_verify utility exits 0 on success, and >0 if an error occurs.

Environment Variables


If the -h option is not specified and the environment variable DB_HOME is set, it is used as the path of the database home, as described in the DB_ENV->open() method.
