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 MariaDB server.

       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=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 exiting.

       •   --mysqltest=path

           The path name to the mysqltest program.

       •   --server-database=db_name

           The database to use for the tests. The default is test.

       •   --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

           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 is /tmp/mysql.sock.

       •   --server-user=user_name

           The MariaDB user name 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 to be run once
           to initialize the database for the testing. 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]

           Use this option to run the stress tests.  file_name is the location of the file that
           contains the list of tests. If file_name is omitted, the default file is
           stress-test.txt in the stress suite directory. (See --stress-suite-basedir.)

       •   --suite=suite_name

           Run the named test suite. The default name is main (the regular 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.

       •   --threads=N

           The number of threads. The default is 1.

       •   --verbose

           Verbose mode. Print more information about what the program does.
