DB5.0_VERIFY(1)
NAME
db5.0_verify - Verifies the structure databases
SYNOPSIS
db5.0_verify [-NoqV] [-h home] [-P password] file ...
DESCRIPTION
The db5.0_verify utility verifies the structure of one or more files
and the databases they contain.
OPTIONS
- -h Specify a home directory for the database environment; by
- default, the current working directory is used.
- -o Skip the database checks for btree and duplicate sort order and
- for hashing.
- If the file being verified contains databases with non-default comparison or hashing configurations, calling the db5.0_verify utility without the -o flag will usually return failure. The -o flag causes db5.0_verify to ignore database sort or hash ordering and allows db5.0_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.
- -N Do not acquire shared region mutexes while running. Other prob
- lems, such as potentially fatal errors in Berkeley DB, will be ignored as well. This option is intended only for debugging errors, and should not be used under any other circumstances.
- -P Specify an environment password. Although Berkeley DB utilities
- overwrite password strings as soon as possible, be aware there may be a window of vulnerability on systems where unprivileged users can see command-line arguments or where utilities are not able to overwrite the memory containing the command-line arguments.
- -q Suppress the printing of any error descriptions, simply exit
- success or failure.
- -V Write the library version number to the standard output, and
- exit.
- The db5.0_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 db5.0_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, db5.0_verify should always be given the chance to detach from the environment and exit gracefully. To cause db5.0_verify to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).
- The db5.0_verify utility exits 0 on success, and >0 if an error occurs.
ENVIRONMENT
- DB_HOME
- 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 DB_ENV->open.
