Restarting a computer that has application components installed

When restarting a computer that performs Server or sensor functions, application components are automatically started. A restart does not affect the subsequent operation of these components (except in some situations when there is a malfunction after an unexpected restart).

A restart may be required in the following cases:

• There is not enough free space on the computer hard drive.
• The computer was unexpectedly restarted, after which the operation of application components was not restored.
• One of the application services is not active.
• A lost connection between the Server and a sensor is not being restored. In this case, you should restart the computer that performs sensor functions.

You can use the standard commands of the operating system to restart a computer that has application components installed.

If the computer cannot be restarted for some reason, you can restart the services that support operation of application components.

To restart the services:

1. Open the operating system console.
2. Depending on which functions are performed by the computer, do the following:
   • If the computer performs Server functions, enter the following sequence of commands:

     sudo service kics4net-fts restart

     sudo service kics4net-postgresql restart

     sudo service kics4net restart

     sudo service kics4net-webserver restart

   • If the computer performs sensor functions, enter the following command:

     sudo service kics4net restart

     sudo service kics4net-websensor restart
