htdb_stat(1)		    General Commands Manual		  htdb_stat(1)

NAME
       htdb_stat -

       displays	statistics for Berkeley	DB environments.

SYNOPSIS
       htdb_stat [-celmNtzW] [-C Acfhlmo] [-d file [-s file]] [-h home]	[-M Ahlm]

DESCRIPTION
       htdb_stat  is  a	 slightly modified version of the standard Berkeley DB
       db_stat utility which displays statistics for Berkeley DB environments.

OPTIONS
       -W     Initialize WordContext(3)	before gathering statistics. With  the
	      -z  flag	allows to gather statistics on inverted	indexes	gener-
	      ated with	the mifluz(3) specific	compression  scheme.  The  MI-
	      FLUZ_CONFIG  environment variable	must be	set to a file contain-
	      ing the mifluz(3)	configuration.

       -z     The file is compressed. If -W is given  the  mifluz(3)  specific
	      compression  scheme is used. Otherwise the default gzip compres-
	      sion scheme is used.

       -C     Display internal information about the lock region.  (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.

       f      Display lock and object free lists.

       l      Display lockers within hash chains.

       m      Display region memory information.

       o      Display objects within hash chains.

       -c     Display lock region statistics.

       -d     Display database statistics for the specified database.  If  the
	      database contains	subdatabases, the statistics are for the data-
	      base or subdatabase specified, and not for  the  database	 as  a
	      whole.

       -e     Display current environment statistics.

       -h     Specify a	home directory for the database.

       -l     Display log region statistics.

       -M     Display  internal	 information  about  the  shared memory	buffer
	      pool.  (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.

       l      Display buffers within LRU chains.

       m      Display region memory information.

       -m     Display shared memory buffer pool	statistics.

       -N     Do  not  acquire shared region locks while running.  Other prob-
	      lems such	as potentially fatal errors in Berkeley	DB will	be ig-
	      nored  as	 well.	This option is intended	only for debugging er-
	      rors and should not be used under	any other circumstances.

       -s     Display database statistics for the specified subdatabase	of the
	      database specified with the -d flag.

       -t     Display transaction region statistics.

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

       Only  one set of	statistics is displayed	for each run, and the last op-
       tion specifying a set of	statistics takes precedence.

       Values smaller than 10 million are generally displayed without any spe-
       cial notation.  Values larger than 10 million are normally displayed as
       <number>M

       The htdb_stat utility attaches to one or	more of	the Berkeley DB	shared
       memory  regions.	 In order to avoid region corruption, it should	always
       be given	the chance to detach and exit gracefully.  To cause  htdb_stat
       to  clean  up  after itself and exit, send it an	interrupt signal (SIG-
       INT).

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.

       MIFLUZ_CONFIG  file  name of configuration file read by WordContext(3).
       Defaults	to ~/.mifluz.
