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 hashing
              configurations, calling the db5.3_verify utility without the -o flag will usually  re‐
              turn  failure.  The -o flag causes db5.3_verify to ignore database sort or hash order‐
              ing 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 com‐
              parison 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 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 sys‐
              tems 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  con‐
       taining  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.
