## NAME
       db5.3_stat - Display statistics for Berkeley DB environments

## SYNOPSIS
       **db5.3**___**stat** -d file [-fN] [-h home] [-P password] [-s database]

       **db5.3**___**stat** [-cEelmNrtVZ] [-C Aclop] [-h home] [-L A] [-M A] [-R A] [-P password]

## DESCRIPTION
       The db5.3_stat utility displays statistics for Berkeley DB environments.

## OPTIONS
### -C
              tion 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

### -d

              If the database contains multiple databases and the **-s** flag is not specified, the sta‐
              tistics are for the internal database that describes the other databases the file con‐
              tains, and not for the file as a whole.

### -E
              subsystems  of  the  database environment.  (The output from this option is often both
              voluminous and meaningless, and is intended only for debugging.)

### -e
              tems of the database environment.

### -f
              database.

### -h
              directory is used.

### -l

### -M
              both voluminous and meaningless, and is intended only for debugging.)

              A      Display all information.

              h      Display buffers within hash chains.

### -m

### -N
              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
              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.

### -R
              option is often both voluminous and meaningless, and is intended only for debugging.)

              A      Display all information.

### -r

### -s
              **-d** flag.

### -t

### -V

### -Z -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 mil‐
       lion are displayed without any special notation, and values larger than 10 million  are  dis‐
       played as a number followed by "M".

       The  db5.3_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  con‐
       taining  a  Berkeley  DB environment).  In order to avoid environment corruption when using a
       Berkeley DB environment, db5.3_stat should always be given the chance to detach from the  en‐
       vironment  and exit gracefully.  To cause db5.3_stat to release all environment resources and
       exit cleanly, send it an interrupt signal (SIGINT).

       The db5.3_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.
