Fix Error: Job Manager Cannot Write to Database

Message

Unable to write data to the job manager database

Possible Cause

If the computer that forms the head node of the MATLAB® Parallel Server™ cluster cannot send data to the client computer, you see this error. The most likely reasons for the remote computer being unable to connect to the client computer are:

  • Firewalls do not allow traffic from the MATLAB Job Scheduler to the client.

  • The MATLAB Job Scheduler cannot resolve the short hostname of the client computer.

Workaround

Add localhost IP to configuration.

  1. In the user interface of the Polyspace® desktop products, select Tools > Preferences.

  2. On the Server Configuration tab, in the Localhost IP address field, enter the IP address of your local computer.

To retrieve your IP address:

  • Windows®

    1. Open Control Panel > Network and Sharing Center.

    2. Select your active network.

    3. In the Status window, click Details. Your IP address is listed under IPv4 address.

  • Linux® — Run the ifconfig command and find the inet addr corresponding to your network connection.

  • Mac — Open System Preferences > Network.
