Install, start, stop, or uninstall mjs service
mjs ... -mjsdef <mjs_defaults_file>
mjs ... -clean
The mjs service ensures that all other processes are running and that it is possible to
communicate with them. Once the mjs service is running, you can use the
nodestatus command to obtain information about the mjs service and all
the processes it maintains.
mjs executable resides in the folder
(Windows® operating system) or
(UNIX® operating system). Enter the following commands at a DOS or UNIX command-line prompt, respectively.
mjs install installs the mjs service in the Microsoft®
Windows Service Control Manager. This causes the service to automatically start when
the Windows operating system boots up. The service must be installed before it is
mjs uninstall uninstalls the mjs service from the Windows Service Control Manager. Note that if you wish to install mjs service as a
different user, you must first uninstall the service and then reinstall as the new
mjs start starts the mjs service. This creates the required logging
and checkpointing directories, and then starts the service as specified in the mjs defaults
mjs stop stops running the mjs service. This automatically stops
all job managers and workers on the computer, but leaves their checkpoint information intact
so that they will start again when the mjs service is started again.
mjs console starts the mjs service as a process in the current
terminal or command window rather than as a service running in the background.
mjs restart performs the equivalent of
mjs start. This command is available only on UNIX and Macintosh operating systems.
mjs ... -mjsdef <mjs_defaults_file> uses the specified
alternative mjs defaults file instead of the one found in
. This file
is provided for Linux (
mjs_def.sh) and Windows
mjs_def.bat). For information on backwards compatibility, see Run Multiple MATLAB Parallel Server Versions.
mjs ... -clean performs a complete cleanup of all service
checkpoint and log files before installing or starting the service, or after stopping or
uninstalling it. This deletes all information about any job managers or workers this service
has ever maintained.
mjs status reports the status of the mjs service, indicating
whether it is running and with what PID. Use
nodestatus to obtain more detailed information about the mjs service. The
mjs status command is available only on UNIX and Macintosh operating systems.
mjs -version prints version information of the mjs process to
standard output, then exits.
mjs -useonlinelicensing ensures that workers use online licensing.
Unless you specify
mjs uses the
network license manager.
