The mysql-stress-test.pl Perl script performs stress-testing of the MySQL server. (MySQL 5.0 and up only)
mysql-stress-test.pl requires a version of Perl that has been built with threads support.
Invoke mysql-stress-test.pl like this:
shell> mysql-stress-test.pl [options
]
mysql-stress-test.pl supports the following options:
Display a help message and exit.
Causes the program to abort if an error with severity less than or equal to N was encountered. Set to 1 to abort on any error.
Periodically check the file that lists the tests to be run. If it has been modified, reread the file. This can be useful if you update the list of tests to be run during a stress test.
Force cleanup of the working directory.
Log error details in the global error log file.
In sequential test mode, the number of loops to execute before exiting.
The path name to the mysqltest program.
The database to use for the tests. The default is

default location is the data
directory
under the location given by the
--stress-suite-basedir
option.
file_name
is the location of the
file that contains the list of tests to be run once to

test suite directory.
This option indicates the test order in stress-test mode.
The mode
