DB_VERIFY(1)                 BerkeleyDB Utilities                 DB_VERIFY(1)

NAME
       db_verify -  Verify the database structure
SYNOPSIS
       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.
OPTIONS
       -h home
              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 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.
       -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 password
              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 argu-
              ments.
       -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 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 inter-
       rupt signal (SIGINT).
EXIT STATUS
       The db_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.
