DB5.1_STAT(1)               General Commands Manual              DB5.1_STAT(1)

NAME
       db5.1_stat - Display statistics for Berkeley DB environments

SYNOPSIS
       db5.1_stat -d file [-fN] [-h home] [-P password] [-s database]

       db5.1_stat  [-cEelmNrtVZ] [-C Aclop] [-h home] [-L A] [-M A] [-R A] [-P
       password]

DESCRIPTION
       The db5.1_stat utility displays statistics  for  Berkeley  DB  environ-
       ments.

OPTIONS
       -C     Display  internal information about the locking subsystem.  (The
              output from this option is often both  voluminous  and  meaning-
              less, and is intended only for debugging.)

              A      Display all information.

              c      Display lock conflict matrix.

              l      Display lockers within hash chains.

              o      Display lock objects within hash chains.

              p      Display locking subsystem parameters.

       -c     Display   locking   subsystem   statistics,   as   described  in
              DB_ENV->lock_stat.

       -d     Display database statistics for the specified file, as described
              in DB->stat.

              If  the  database contains multiple databases and the -s flag is
              not specified, the statistics are for the internal database that
              describes the other databases the file contains, and not for the
              file as a whole.

       -E     Display internal information  about  the  database  environment,
              including all configured subsystems of the database environment.
              (The output from this option is often both voluminous and  mean-
              ingless, and is intended only for debugging.)

       -e     Display  information  about  the database environment, including
              all configured subsystems of the database environment.

       -f     Display only those database  statistics  that  can  be  acquired
              without traversing the database.

       -h     Specify  a  home  directory  for  the  database  environment; by
              default, the current working directory is used.

       -l     Display  logging   subsystem   statistics,   as   described   in
              DB_ENV->log_stat.

       -M     Display  internal information about the cache.  (The output from
              this option is often both voluminous  and  meaningless,  and  is
              intended only for debugging.)

              A      Display all information.

              h      Display buffers within hash chains.

       -m     Display cache statistics, as described in DB_ENV->memp_stat.

       -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     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.

       -R     Display  internal  information  about the replication subsystem.
              (The output from this option is often both voluminous and  mean-
              ingless, and is intended only for debugging.)

              A      Display all information.

       -r     Display     replication     statistics,    as    described    in
              DB_ENV->rep_stat.

       -s     Display statistics for the specified database contained  in  the
              file specified with the -d flag.

       -t     Display   transaction  subsystem  statistics,  as  described  in
              DB_ENV->txn_stat.

       -V     Write the library version number to  the  standard  output,  and
              exit.

       -Z     Reset  the  statistics after reporting them; valid only with the
              -C, -c, -E, -e, -L, -l, -M, -m, -R, -r, and -t options.

       Values normally displayed in quantities of bytes  are  displayed  as  a
       combination  of  gigabytes  (GB),  megabytes  (MB), kilobytes (KB), and
       bytes (B).  Otherwise, values smaller than  10  million  are  displayed
       without  any  special  notation,  and values larger than 10 million are
       displayed as a number followed by "M".

       The db5.1_stat 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_stat should always be given  the  chance
       to   detach  from  the  environment  and  exit  gracefully.   To  cause
       db5.1_stat to release all environment resources and exit cleanly,  send
       it an interrupt signal (SIGINT).

       The db5.1_stat 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.
