System Services vs User Services

The Mediatrix unit uses many services to carry out tasks and support features.

There are 3 service commands that can be used:
  • Start
  • Stop
  • Restart
The are two types of services:
Note: Available services may differ depending on the Mediatrix unit you are using. Furthermore, some services are available only if a licence has been installed. Available services are displayed on the DGW Web page, under System/Services.

When a system or a user service needs to be restarted, the Some changes require to restart a service to apply new configuration message is systematically displayed on the DGW Web pages. Also, every service has the NeedRestartInfo CLI/MIB parameter to indicate if the service needs to be restarted for the configuration to fully take effect.

Note: For the complete list of parameters and commands available for the configuration of each service, refer to the DGW Configuration Guide - Reference Guide published on the Media5 Documentation Portal.

Basic Tasks

Setting the Service Start-up Type

Steps
  1. Go to System/Services.
  2. In the User Service table, from the Startup Type selection list located next to the service you wish to set.
    • choose Auto if you wish the service to start automatically when the system starts, or
    • choose Manual to start to the service manually when needed.
  3. Click Apply.
Result
The services set to Auto will automatically start every time the unit boots, while the services set to Manual must be started each time by the administrator when needed.

Starting/Stopping/Restarting a User Service Using the DGW Web Page

Steps
  1. Go to System/Services.
  2. In the User Service table, on the line of the service you wish to set.
    • click if you wish to start the service, or
    • click to restart the service.
    • click to stop the service.
    Note: When stopping or restarting a service, some interruptions might occur, such as dropped calls, virtual machine shutdown or loss of network connectivity, depending on the affected services and/or its dependencies.
  3. Click Apply.
Result
The status of the service (in the Status column) changes following the executed service command.
  • If you clicked , the tab from which you can access the service from the Web pages are greyed out
  • If you clicked , the tab from which you can access the service from the Web pages are no longer greyed out.

Disabling a Service

Steps
  1. Go to System/Services.
  2. In the User Service table, on the line of the service you wish to disable, click to stop the service.
    Note: When stopping a service, some interruptions might occur, such as dropped calls, virtual machine shutdown or loss of network connectivity, depending on the affected services and/or its dependencies.
  3. In the User Service table, from the Startup Type selection list located next to the service you wish to disable, choose Manual.
  4. Click Apply.
Result
The service will be stopped and will not be restarted automatically at the next unit start-up.

Restarting a Service with a Grace Delay

Context
If no service needs to be restarted, the table will be greyed out.
Steps
  1. Go to System/Services.
  2. In the Restart Required Services table, set the Graceful Delay (min) field.
  3. Click Restart Required Services.
Result
The services that require a restart are restarted after the delay allowing ongoing calls to be completed. At the expiration of the delay, the services are forced to restart even if calls are still ongoing. Therefore, ongoing calls are abruptly disconnected without proper release. The users are not informed of the call disconnection event (ex.: end-of-call tone).

Restarting a System Service

Context
System services cannot be restarted by the user. To restart a system service, the unit must be restarted.
Steps
  1. Go to Reboot.
  2. In the Reboot page, click Reboot .
    Note: If the unit is in use when clicking Reboot, all calls are terminated.
Result
The Web session will be lost and you will be redirected to the login page after the reboot process. All system services needing to be restarted, will be restarted.

Steps
  1. Open a MIB Browser
  2. Navigate to the Service that needs to be restarted.
  3. Locate the needRestartInfo parameter to determine if the service needs to be restarted.
  4. In the scmMIB, locate the serviceCommandsTable .
  5. In the serviceCommandsName column, locate the service to restart.
    1. To restart the service, set the serviceCommandsRestart column to restart
    2. To start the service, set the serviceCommandsStart column to Start

DGW Documentation

Mediatrix devices are supplied with an exhaustive set of documentation.

Mediatrix user documentation is available on the Media5 Documentation Portal.

Several types of documents were created to clearly present the information you are looking for. Our documentation includes:
  • Release notes: Generated at each GA release, this document includes the known and solved issues of the software. It also outlines the changes and the new features the release includes.
  • Configuration notes: These documents are created to facilitate the configuration of a specific use case. They address a configuration aspect we consider that most users will need to perform. However, in some cases, a configuration note is created after receiving a question from a customer. They provide standard step-by-step procedures detailing the values of the parameters to use. They provide a means of validation and present some conceptual information. The configuration notes are specifically created to guide the user through an aspect of the configuration.
  • Technical bulletins: These documents are created to facilitate the configuration of a specific technical action, such as performing a firmware upgrade.
  • Hardware installation guide: They provide the detailed procedure on how to safely and adequately install the unit. It provides information on card installation, cable connections, and how to access for the first time the Management interface.
  • User guide: The user guide explains how to customise to your needs the configuration of the unit. Although this document is task oriented, it provides conceptual information to help the user understand the purpose and impact of each task. The User Guide will provide information such as where and how TR-069 can be configured in the Management Interface, how to set firewalls, or how to use the CLI to configure parameters that are not available in the Management Interface.
  • Reference guide: This exhaustive document has been created for advanced users. It includes a description of all the parameters used by all the services of the Mediatrix units. You will find, for example, scripts to configure a specific parameter, notification messages sent by a service, or an action description used to create Rulesets. This document includes reference information such as a dictionary, and it does not include any step-by-step procedures.
