DB5.3_VERIFY(1)                      General Commands Manual                      DB5.3_VERIFY(1)



NAME
       db5.3_verify -  Verifies the structure databases

SYNOPSIS
       db5.3_verify [-NoqV] [-h home] [-P password] file ...

DESCRIPTION
       The  db5.3_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 hash‐
              ing configurations, calling the db5.3_verify utility without the -o flag will  usu‐
              ally  return  failure.   The -o flag causes db5.3_verify to ignore database sort or
              hash ordering and allows db5.3_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 problems, such as poten‐
              tially  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  circum‐
              stances.

       -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 db5.3_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 db5.3_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, db5.3_verify should always be given the chance to detach
       from the environment and exit gracefully.  To cause db5.3_verify to release  all  environ‐
       ment resources and exit cleanly, send it an interrupt signal (SIGINT).

       The db5.3_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.
