db_verify [-NoqV] [-h home] [-P password] file ...Description
The db_verify utility verifies the structure of one or more files and the databases they contain.
The options are as follows:
If the file being verified contains databases with non-default comparison or hashing configurations, calling the db_verify utility without the -o flag will usually return failure. The -o flag causes db_verify to ignore database sort or hash ordering and allows db_verify to be used on these files. To fully verify these files, verify them explicitly using the DB->verify method, after configuring the correct comparison or hashing functions.
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.
