NAME - server stress test program

SYNOPSIS [options]

       The Perl script performs stress-testing of the
       MySQL server. (MySQL 5.0 and up only) requires a version of Perl that has been built
       with threads support.

	   shell> [options] supports the following options:

       ·   --help

	   Display a help message and exit.

       ·   --abort-on-error=N

	   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.

       ·   --check-tests-file

	   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.

       ·   --cleanup

	   Force cleanup of the working directory.

       ·   --log-error-details

	   Log error details in the global error log file.

       ·   --loop-count=N

	   In sequential test mode, the number of loops to execute before

       ·   --server-host=host_name

	   The host name of the local host to use for making a TCP/IP
	   connection to the local server. By default, the connection is made
	   to localhost using a Unix socket file.

       ·   --server-logs-dir=path

	   This option is required.  path is the directory where all client
	   session logs will be stored. Usually this is the shared directory
	   that is associated with the server used for testing.

       ·   --server-password=password

	   The password to use when connecting to the server.

       ·   --server-port=port_num

	   default is root.

       ·   --sleep-time=N

	   The delay in seconds between test executions.

       ·   --stress-basedir=path

	   This option is required.  path is the working directory for the
	   test run. It is used as the temporary location for result tracking
	   during testing.

       ·   --stress-datadir=path

	   The directory of data files to be used during testing. The default
	   location is the data directory under the location given by the
	   --stress-suite-basedir option.

       ·   --stress-init-file[=path]

	   file_name is the location of the file that contains the list of
	   tests to be run once to initialize the database for the testing. If
	   missing, the default file is stress_init.txt in the test suite

       ·   --stress-mode=mode

	   This option indicates the test order in stress-test mode. The mode
	   value is either random to select tests in random order or seq to
	   run tests in each thread in the order specified in the test list
	   file. The default mode is random.

       ·   --stress-suite-basedir=path

	   This option is required.  path is the directory that has the t and
	   r subdirectories containing the test case and result files. This

       ·   --test-count=N

	   The number of tests to execute before exiting.

       ·   --test-duration=N

	   The duration of stress testing in seconds.

       ·   --threads=N
