       A customized version of the Berkeley Database (Berkeley DB) is embedded
       in  the	operating  system to provide high-performance database support
       for critical security files. The DB includes full transactional support
       and  database  recovery, using write-ahead logging and checkpointing 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 spe‐
       cial  notation. Values larger than 10 million are normally displayed as

       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

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

       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.



       Commands: db_archive(8), db_checkpoint(8), db_printlog(8),  db_dump(8),
