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   hashing
              configurations,  calling the db5.3_verify utility without the -o flag will usually 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  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  db5.3_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 environment 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.
