NAME
       mysql-stress-test.pl - server stress test program

SYNOPSIS
       mysql-stress-test.pl [options]

DESCRIPTION
       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:

       ·  --help

	  Display a help message and exit.

       ·  --abort-on-error

	  Unknown.

       ·  --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
	  exiting.

       ·  --mysqltest=path

	  The pathname to the mysqltest program.

       ·  --server-database=db_name

	  The database to use for the tests.

       ·  --server-host=host_name

	  The hostname 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

	  The TCP/IP port number to use for connecting to the server. The
	  default is 3306.

       ·  --server-socket=file_name

	  For connections to localhost, the Unix socket file to use, or, on
	  Windows, the name of the named pipe to use. The default if
	  /tmp/mysql.sock.

       ·  --server-user=user_name

	  The MySQL username to use when connecting to the server. The
	  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. If missing, the default file is stress_init.txt in the test
	  suite directory.

       ·  --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
	  directory is also the default location of the stress-test.txt file
	  that contains the list of tests. (A different location can be
	  specified with the --stress-tests-file option.)

       ·  --stress-tests-file[=file_name]

	  of the file that contains the list of tests. If file_name is

	  test suite located in the mysql-test directory).

       ·  --test-count=N

	  The number of tests to execute before exiting.

       ·  --test-duration=N

	  The duration of stress testing in seconds.
