DB_TUNER(1)                  BerkeleyDB Utilities                  DB_TUNER(1)

NAME
       db_tuner - analyze and tune btree database
SYNOPSIS
       db_tuner [-c cachesize] -d file [-h home] [-s database] [-v]
DESCRIPTION
       The  db_tuner  utility  analyzes the data in a btree database, and sug-
       gests a page size that is likely to deliver optimal operation.
OPTIONS
       -c cachesize
              Specify a value of the cachesize, otherwise, the  default  value
              will be set.
       -d file
              Display database statistics for the specified file. If the data-
              base contains multiple databases and the -s flag is  not  speci-
              fied,   the  statistics  are  for  the  internal  database  that
              describes the other databases the file contains, and not for the
              file as a whole.
       -h home
              Specify a home directory for the database environment.
       -s database
              Display page size recommendation for the specified database con-
              tained in the file specified with the -d flag.
       -v     Display verbose information.
NOTES
       The  db_tuner  utility  assumes  that  databases  are  compacted   when
       analysing the data.  The analysis is based on a static view of the data
       and the data access and update patterns are not take into account.
