MATLAB: When stopping the MATLAB Production Server instance why do I receive “Error: Unable to stop the server service: The service has not been started”

MATLAB Production Server

When trying to stop the MATLAB Production Server instance using mps-stop within the instance folder, why do I receive "Error: Unable to stop the server service: The service has not been started"?

Best Answer

This error will typically occur if a Windows Service has been configured for the server instance. In order to stop the instance you will need to remove the service first.Run the command mps-service delete within the server instance folder.

For example:C:\MPS\mps_instance\mps-service delete

Then run mps-stop:C:\MPS\prod_server_1\mps-stop\mps-stop

The instance should stop and you can make changes if necessary and restart the instance.

MATLAB: How to access a Matlab Production Server instance on a virtual machine with RESTful API

In this Bond pricing example, assuming the hostname of your virtual machine is VM_HOST, you need to change the following line of calculatePrice.js.

var url = "http://VM_HOST:9910/BondTools/pricecalc";

Because calling MATLAB Production Server is based on HTTP or HTTPS on TCP, so you don't need to specify the actual server path of MATLAB Production Server. In this example, BondTools is CTF name and pricecalc is MATLAB function name.

Also, since you're accessing MATLAB Production Server from different host, I mean, client (HTML file) is on physical machine (let's say hostname is YOUR_HOST) and MATLAB Production Server is on virtual machine(VM_HOST, you need to set Cross-Origin Resource Sharing (CORS) properly in config/main_config file. If you want to allow accessing from only YOUR_HOST, you need to change cors-allowed-origins as follows,

--cors-allowed-origins http://YOUR_HOST

or if you want to allow accessing from any host,

--cors-allowed-origins *

If you're using MATLAB Production Server R2017a, you can use dashboard and it's easier to deploy ctf, change HTTP/HTTPS settings and resources, and monitor the status of MATLAB Production Server instances. To setup MATLAB Production Server dashboard, please see this doc; Set Up and Log In to MATLAB Production Server Dashboard

MATLAB: When starting a MATLAB Production Server instance, why to do I receive “Server process exited with return code: 7”

In cases where there are more than one instance running on the same machine you will need to specify a new port in the main_config file located in the instance folder

C:\MPS\mps_instance\config\

The default port is 9910. You will need to verify if this port is already in use. Once the change has been made you may try starting the instance again.

If the port was previously used by MATLAB Production Server, but is not free, then we kill the process listening to this port as shown:

Windows:

1. Search the task manager for mps_master_app.exe, select it and kill it.

Linux:

PID of the Server process and kill it gracefully as show:

1. Execute the following command on the terminal:

netstat -aon | grep <Port>

2. You can then gracefully kill this process using the 'kill' command as shown:

kill -15 <PID>
