Starting and stopping services

In this recipe, I will explain how you can restart the services of all the main components in your Data Services environment.

How to do it…

This relates to the three different services:

• Web application server:
  • The Tomcat application server configured in our environment can be configured from two places:

    Computer Management | Services and Applications | Services where it exists as a standard Windows service BOEXI40Tomcat

    Central Configuration Management tool installed as a part of IPS product package:

  

  Using this tool, you can:

  1. Start/stop services.
  2. Back up and restore system configuration.
  3. Specify the Windows user who starts and stops the underlying services.
• Data Services Job Server:
  • To manage Data Services Job Server in the Windows environment, SAP created a separate GUI application called Data Services Server Manager.
  • Using this tool, you can perform the following tasks:
  1. Restart Job Server.
  2. Create and configure Job Servers.
  3. Create and configure Access Servers.
  4. Perform SSL configuration.
  5. Set up a pageable cache directory.
  6. Perform SMTP configuration for the smpt_to() Data Services function.
• Information Platform Services:
  • To manipulate these services, you have two options:

    Central Management Console (to stop/start and configure services parameters)

    Central Configuration Management (to stop/start services)

In most cases, you will be using the CMC option, as it is a quick and convenient way to access all services included in the IPS package. It also allows you to see much more service-related information.

The second option is useful if you have the application server stopped for some reason (CMC as a web-based application will not be working, of course), and you still need to access IPS services to perform basic administration tasks such as restarting them, for example.

How it works…

Sometimes, things turn sour, and restarting services is the quickest and easiest option to return them to a normal state. In this recipe, I mentioned all the main server components and points of access to perform such a task.

The last thing you should keep in mind regarding this is the recommended startup/shutdown sequences of those components.

1. The first thing that should start after Windows starts is your database server, as it hosts the CMS database required for the IPS services and Data Services local repository.
2. Second, you should start IPS services (the main one is the CMS service) as an underlying level for Data Services.
3. Then, it is the turn of the Data Services Job Server.
4. Finally, it goes to Tomcat (web application server) that provides users with access to web-based applications.
