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 environments.

OPTIONS

       -C     Display  internal  information  about the locking subsystem.  (The output from this option is often both voluminous and meaningless,
	      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 meaningless, 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 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.

       -R     Display internal information about the replication subsystem.  (The output from this option is often both  voluminous  and  meaning-
	      less, 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.
