NAME

       db_stat - Displays statistics for the database files (Enhanced Security)

SYNOPSIS

       /usr/tcb/bin/db_stat [-clmNt] [-C Acfhlmo] [-d file]
	    [-h home] [-M Ahlm]

FLAGS

       Display internal information about the lock region.  (The output from this option is often both voluminous and meaningless, and is intended
       only for debugging.)  Display all information.  Display lock conflict matrix.  Display lock and object free lists.  Display lockers  within
       hash  chains.   Display	region memory information.  Display objects within hash chains.  Display lock region statistics.  Display database
       statistics for the specified database.  Specify a home directory for  the  database.   The  correct  directory  for  enhanced  security	is
       /var/tcb/files.	 Display  log region statistics.  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.)  Display all  information.   Display  buffers  within
       hash chains.  Display buffers within LRU chains.  Display region memory information.  Display shared memory buffer pool statistics.  Do not
       acquire shared region locks while accumulating the statistics.  This option is intended only for debugging corrupt regions and  should  not
       be used under any other circumstances.  Display transaction region statistics.

DESCRIPTION

       A  customized  version of the Berkeley Database (Berkeley DB) is embedded in the operating system to provide high-performance database sup-
       port for critical security files.  The DB includes full transactional support and database recovery, using write-ahead logging  and  check-
       pointing to record changes.

       The  db_stat  utility  provides database statistics for these security files.  Customization for Tru64 UNIX makes some of this information,
       particularly lock-related information, meaningless.

       Values smaller than 10 million are generally displayed without any special notation.  Values larger than 10 million are normally  displayed
       as M.

       The  db_stat  utility  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 db_stat to clean up after itself and exit, send it an  interrupt
       signal (SIGINT).

RETURN VALUES

       The db_stat utility exits 0 on success, and >0 if an error occurs.

ENVIRONMENT VARIABLES

       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.  The home
       directory for security is /var/tcb/files.

FILES

       /var/tcb/files/auth.db

       /var/tcb/files/dblogs/*
