- The MySQL benchmarks Ver $benchmark_version
- All benchmarks takes the following options:
- --comments
- Add a comment to the benchmark output. Comments should contain
- extra information that 'uname -a' doesn't give and if the database was
- stared with some specific, non default, options.
- --cmp=server[,server...]
- Run the test with limits from the given servers. If you run all servers
- with the same --cmp, you will get a test that is comparable between
- the different sql servers.
- --create-options=#
- Extra argument to all create statements. If you for example want to
- create all MySQL tables as BDB tables use:
- --create-options=TYPE=BDB
- --database (Default $opt_database)
- In which database the test tables are created.
- --debug
- This is a test specific option that is only used when debugging a test.
- Print out debugging information.
- --dir (Default $opt_dir)
- Option to 'run-all-tests' to where the test results should be stored.
- --fast
- Allow the database to use non standard ANSI SQL commands to make the
- test go faster.
- --fast-insert
- Use "insert into table_name values(...)" instead of
- "insert into table_name (....) values(...)"
- If the database supports it, some tests uses multiple value lists.
- --field-count
- This is a test specific option that is only used when debugging a test.
- This usually means how many fields there should be in the test table.
- --force
- This is a test specific option that is only used when debugging a test.
- Continue the test even if there is some error.
- Delete tables before creating new ones.
- --groups (Default $opt_groups)
- This is a test specific option that is only used when debugging a test.
- This usually means how many different groups there should be in the test.
- --lock-tables
- Allow the database to use table locking to get more speed.
- --log
- Option to 'run-all-tests' to save the result to the '--dir' directory.
- --loop-count (Default $opt_loop_count)
- This is a test specific option that is only used when debugging a test.
- This usually means how many times times each test loop is executed.
- --help
- Shows this help
- --host='host name' (Default $opt_host)
- Host name where the database server is located.
- --machine="machine or os_name"
- The machine/os name that is added to the benchmark output filename.
- The default is the OS name + version.
- --odbc
- Use the ODBC DBI driver to connect to the database.
- --password='password'
- Password for the current user.
- --regions
- This is a test specific option that is only used when debugging a test.
- This usually means how AND levels should be tested.
- --old-headers
- Get the old benchmark headers from the old RUN- file.
- --server='server name' (Default $opt_server)
- Run the test on the given SQL server.
- Known servers names are: Access, Adabas, AdabasD, Empress, Oracle,
- Informix, DB2, mSQL, MS-SQL, MySQL, Pg, Solid and Sybase
- --silent
- Don't print info about the server when starting test.
- --skip-delete
- This is a test specific option that is only used when debugging a test.
- This will keep the test tables after the test is run.
- --skip-test=test1[,test2,...]
- For run-all-programs; Don't execute the named tests.
- --small-test
- This runs some tests with smaller limits to get a faster test.
- Can be used if you just want to verify that the database works, but
- don't have time to run a full test.
- --small-tables
- This runs some tests that generate big tables with fewer rows.
- This can be used with databases that can't handle that many rows
- because of pre-sized partitions.
- --suffix (Default $opt_suffix)
- The suffix that is added to the database name in the benchmark output
- filename. This can be used to run the benchmark multiple times with
- different server options without overwritten old files.
- When using --fast the suffix is automaticly set to '_fast'.
- --tcpip
- Inform test suite that we are using TCP/IP to connect to the server. In
- this case we cant do many new connections in a row as we in this case may
- fill the TCP/IP stack
- --time-limit (Default $opt_time_limit)
- How long a test loop is allowed to take, in seconds, before the end result
- is 'estimated'.
- --use-old-results
- Option to 'run-all-tests' to use the old results from the '--dir' directory
- instead of running the tests.
- --user='user_name'
- User name to log into the SQL server.
- --verbose
- This is a test specific option that is only used when debugging a test.
- Print more information about what is going on.
