The mdce service ensures that all other processes are running and that it is possible to
communicate with them. Once the mdce service is running, you can use the
nodestatus command to obtain information about the mdce service and all
the processes it maintains.
The mdce executable resides in the folder
(Windows® operating system) or
matlabroot\toolbox\distcomp\bin (UNIX® operating system). Enter the following commands at a DOS or UNIX command-line prompt, respectively.matlabroot/toolbox/distcomp/bin
mdce install installs the mdce 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
started.
mdce uninstall uninstalls the mdce service from the Windows Service Control Manager. Note that if you wish to install mdce service as a
different user, you must first uninstall the service and then reinstall as the new
user.
mdce start starts the mdce service. This creates the required
logging and checkpointing directories, and then starts the service as specified in the mdce
defaults file.
mdce stop stops running the mdce 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 mdce service is started again.
mdce console starts the mdce service as a process in the current
terminal or command window rather than as a service running in the background.
mdce restart performs the equivalent of mdce
stop followed by mdce start. This command is available only
on UNIX and Macintosh operating systems.
mdce ... -mdcedef <mdce_defaults_file> uses the specified
alternative mdce defaults file instead of the one found in
. This file
is provided for Linux (matlabroot/toolbox/distcomp/binmdce_def.sh) and Windows
(mdce_def.bat). Also see the Backwards Compatibility Note in Install Products and Choose Cluster Configuration.

mdce ... -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.
mdce status reports the status of the mdce service, indicating
whether it is running and with what PID. Use nodestatus to obtain more detailed information about the mdce service. The
mdce status command is available only on UNIX and Macintosh operating systems.
mdce -version prints version information of the mdce process to
standard output, then exits.
mdce -usemhlm ensures that workers use MathWorks® Hosted License Manager. Unless you specify –usemhlm, mdce
uses FlexLM-based licensing.
