NAME

       db5.1_verify -  Verifies the structure databases

SYNOPSIS

       db5.1_verify [-NoqV] [-h home] [-P password] file ...

DESCRIPTION

       The  db5.1_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 db5.1_verify utility without the -o  flag  will
              usually return failure.  The -o flag causes db5.1_verify to ignore database sort or
              hash ordering and allows db5.1_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 db5.1_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 db5.1_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, db5.1_verify should always be given the chance to detach
       from  the  environment  and  exit  gracefully.   To  cause  db5.1_verify  to  release  all
       environment resources and exit cleanly, send it an interrupt signal (SIGINT).

       The db5.1_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.
