SAP Data Services 4.x Cookbook

Chapter 2. Configuring the Data Services Environment

In this chapter, we will install and configure all components required for SAP Data Services. In this chapter, we will cover the following topics:

  • Creating IPS and Data Services repositories
  • Installing and configuring Information Platform Services
  • Installing and configuring Data Services
  • Configuring user access
  • Starting and stopping services
  • Administering tasks
  • Understanding the Designer tool

Introduction

The same thing that makes SAP Data Services a great ETL development environment makes it quite not a trivial one to install and configure. Here though, you have to remember that Data Services is an enterprise class ETL solution that is able to solve the most complex ETL tasks.

See the following image for a very high-level Data Services architecture view. Data Services has two basic groups of components: client tools and server-based components:

Introduction

Client tools include the following (there are more, but we mention the ones most often used):

  • The Designer tool: This is the client-based main GUI application for ETL development
  • Repository Manager: This is a client-based GUI application for Data Services to create, configure, and upgrade Data Services repositories

The main server-based components include the following ones:

  • IPS Services: This is used for user authentication, system configuration storage, and internal metadata management
  • Job Server: This is a core engine service that executes...

Creating IPS and Data Services repositories

The IPS repository is a storage for environment and user configuration information and metadata collected by various services of IPS and Data Services. It has another name: the CMS database. This name should be quite familiar to those who have used SAP Business Intelligence software. Basically, IPS is a light version of SAP BI product package. You will always use only one IPS repository per Data Services installation and most likely will deal with it only once: when configuring the environment at the very beginning. Most of the time, Data Services will be communicating with IPS services and the CMS database in the background, without you even noticing.

The Data Services repository is a different story. It is much closer to an ETL developer as it is a database that stores your developed code. In a multiuser development environment, every ETL developer usually has its own repository. They can be of two types: central and local. They serve different...

Installing and configuring Information Platform Services

The Information Platform Services (IPS) product package was added as a component into the Data Services bundle starting from the Data Services 4.x version. The reason for this was to make the Data Services architecture flexible and robust and introduce some extra functionality, that is, a user management layer to the existing SAP Data Services solution. As we mentioned before, IPS is a light version of SAP BI core services and has a lot of similar functionality.

In this recipe, we will perform the installation and basic configuration of IPS, which is a mandatory component for future Data Services installations.

Tip

As an option, you could always use the existing full enterprise SAP BI solution if you have it installed in your environment. However, this is generally considered a bad practice. Imagine that it is like storing all eggs in one basket. Whenever you need to plan downtime for your BI system, you should keep in mind that it will...

Installing and configuring Data Services

The installation of Data Services in a Windows environment is a smooth and quick process. Of course, you have various installation options, but here, we will choose the easiest path: the full installation of all components on the same host with IPS services installed and the local repository already created and configured.

Getting ready…

Completion of the previous recipe should prepare your environment to install Data Services. Download the Data Services installation package from the SAP support portal and unzip it to a local folder.

How to do it…

  1. Start Data Services from Windows command line (cmd) by executing this command:
    setup.exe SERVERINSTALL=Yes
    
  2. Make sure that all your critical prerequisites have the Succeeded status on the Check Prerequisites screen.
  3. Choose the destination folder as C:\EIM\ if required.
  4. On the CMS connection information step, specify the connection details to your previously installed CMS (part of IPS) installation...

Configuring user access

In this recipe, I will show you how to configure your access as a fresh ETL developer in a Data Services environment. We will create a user account, assign all the required functional privileges, and assign owner privileges for our local Data Services repository. In a multiuser development environment, you would require to perform this step for every newly created user.

Getting ready…

Choose the username and password for your ETL developer user account. We will log in to the CMC application to create a user account and grant it the required set of privileges.

How to do it…

  1. Launch the Central Management Console web application.
  2. Go to Users and Groups.
  3. Click on Create a user button (see the following screenshot):
    How to do it…
  4. In the opened window, choose a username (we picked etl) and password. Also, select the Password never expires option and unselect User must change password at next logon. Choose Concurrent User as the connection type.
  5. Now, we should add our newly created...

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:

    How to do it…

    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...

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
