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 suggests 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 database contains multiple databases and the -s flag is not specified, 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 contained 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.
