Installation guide

Overview

Refer to the readme file for information about installation issues and limitations for Data Studio.

IBM Installation Manager

Regardless of which installation scenario you follow to install Data Studio on your workstation, use Installation Manager to install your package.

IBM Installation Manager offers a number of time-saving features. It keeps track of what you are about to install, software components that you have already installed, and components that are available for you to install. It searches for updates so you know that you are installing the latest version of a product package. Installation Manager also provides tools for managing licenses for the product packages that it installs. It provides tools for updating and modifying packages. You can also use Installation Manager to uninstall product packages.

IBM Installation Manager comprises five wizards that make it easy to maintain your product packages through their lifecycles:

• The Install Packages wizard walks you through the installation process. You can install a product package by simply accepting the defaults, or you can modify the default settings to create a custom installation. Before you install a product package, you are provided with a complete summary of the selections that you have made throughout the wizard. With the wizard you can install one or more product packages at the same time.
• The Update Packages wizard searches for available updates to product packages that you have installed. An update might be a released fix, a new feature, or a new version of the product. Details of the contents of the update are provided in the wizard. You can choose whether to apply an update.
• With the Modify Packages wizard you can modify specific elements of a package that you have already installed. During your initial installation of the product package, you select the features you want to install. If you find later that you require other features, you can use the Modify Packages wizard to add them to your product package installation. You can also remove features, and add or remove languages.

• The Manage Licenses wizard helps you to set up the licenses for your packages. Use this wizard to change your trial license to a full license and to select which type of license to use for each package.
• The Uninstall Packages wizard helps you to remove a product package from your computer. You can uninstall more than one package at a time.

Planning to install

Installation scenarios

The following are some of the factors that might determine your installation scenario:

• The format and method by which you access your installation files (for example, from CDs or files downloaded from IBM Passport Advantage^(R)).
• The location for your installation (for example, you can install the product onto your own workstation, or make the installation files available to your enterprise.
• The type of installation (for example, you can use the Installation Manager GUI, or install silently).

These are the typical installation scenarios you might follow:

• Installing from the CDs.
• Installing from a downloaded electronic image on your workstation.
• Installing from an electronic image on a shared drive.

Note that in the latter three scenarios you can choose to run the Installation Manager program in silent mode to install Data Studio. For details on running Installation Manager in silent mode, see Installing silently.

Installing from CDs

In this installation scenario, you have the CDs that contain the product package files, and typically you are installing Data Studio on your own workstation. Refer to Installing Data Studio from CDs: task overview for an overview of the steps.

Installing from a downloaded electronic image on your workstation

In this scenario, you have downloaded the installation files from IBM Passport Advantage and you will install Data Studio on your own workstation. Refer to Installing Data Studio from an electronic image on your workstation: task overview for an overview of the steps.

Installing from an electronic image on a shared drive

In this scenario, you will place the electronic image on a shared drive so that users in your enterprise can access the installation files for Data Studio from a single location. Refer to Installing Data Studio from an electronic image on a shared drive: task overview for an overview of the steps.

Deciding which features to install

When you install the Data Studio product package using IBM Installation Manager, the installation wizard displays the features in the available product package. From the features list, you can select which to install. A default set of features is selected for you (including any required features). Installation Manager automatically enforces any dependencies between features and prevents you from clearing any required features.

Features

Installation repositories

If the LaunchPad is used to start Installation Manager, the repository information is passed to Installation Manager. If the Installation Manager is started directly, you must specify an installation repository that contains the product packages that you want to install. SeeSetting repository preferences in Installation Manager.

By default, IBM Installation Manager uses an embedded URL in each product to connect to a repository server over the Internet. Installation Manager then searches for the product packages as well as new features.

Setting repository preferences in Installation Manager

To add, edit, or remove a repository location in Installation Manager:

1. Start Installation Manager.
2. On the Start page of Installation Manager, click File -> Preferences, and then click Repositories. The Repositories page opens, showing any available repositories, their locations, and whether they are accessible.
3. On the Repositories page, click Add Repository.
4. In the Add repository window, type the URL of the repository location or browse to it and set a file path.
5. Click OK. If you entered a HTTPS repository location, then you will be prompted to enter a user ID and password. The new or changed repository location is listed. If the repository is not accessible, a red x is displayed in the Accessible column.
6. Click OK to exit.

Package groups and the shared resource directory

Package groups

During the installation process, you must specify a package group for the Data Studio package. A package group represents a directory in which packages share resources with other packages in the same group. When you install the Data Studio package with Installation Manager, you can create a new package group or install the packages into an existing package group. (Some packages might not be able to share a package group, in which case the option to use an existing package group will be disabled.)

Note that when you install multiple packages at the same time, all the packages are installed into the same package group.

A package group is assigned a name automatically; however, you choose the installation directory for the package group.

After you create the package group by successfully installing a product package, you cannot change the installation directory. The installation directory contains files and resources specific to the Data Studio product package installed into that package group. Resources in the product package that can potentially be used by other package groups are placed in the shared resources directory.

Shared resources directory

The shared resources directory is the directory where installation artifacts are located so that they can be used by one or more product package groups.

Extending an existing Eclipse IDE

The Data Studio package that you install with IBM Installation Manager is bundled with a version of the Eclipse IDE or workbench; this bundled workbench is the base platform for providing the functionality in the Installation Manager package. However, if you have an existing Eclipse IDE on your workstation, then you have the option to extend, that is, add to the IDE the additional functionality provided in the Data Studio package - that Eclipse instance.

To extend and existing Eclipse IDE: in the Location page of the Install Packages wizard, select the Extend an existing Eclipse IDE option.

You might extend your existing Eclipse IDE, for example, because you want to gain the functionality provided in the Data Studio package, but you also want to have the preferences and settings in your current IDE when you work with the functionality from the Data Studio package. You also might want to work with plug-ins you have installed that already extend the Eclipse IDE.

Your existing Eclipse IDE must be version 3.2.2 or later to be extended. Installation Manager checks that the Eclipse instance you specify meets the requirements for the installation package.

Verifying and extracting electronic images

You can compare the published MD5 values with the checksum of the downloaded files to check if the downloaded file is corrupt or incomplete.

Extracting the downloaded files

Extract each compressed file to the same directory.

Preinstallation tasks

1. Confirm that your system meets the requirements described in the section Installation requirements.
2. Confirm that the directory pointed to by your environment variable TEMP has at least 100 MB free. This is in addition to the space required for installing the product.
3. Confirm that your user ID meets the required access privileges for installing the product. See User privileges requirements.

Installing silently

Running Installation Manager in silent mode is helpful because it enables you to use a batch process to install, update, modify and uninstall product packages through scripts.

Note that you must install Installation Manager before you can silently install the Data Studio package. Refer to Managing IBM Installation Manager for details on installing Installation Manager.

There are two main tasks required for silent installation:

1. Create the response file.
2. Run Installation Manager in silent installation mode.

Creating a response file

To record a response file for installation (or uninstallation):

1. On a command line, change to the eclipse subdirectory in the directory where you installed Installation Manager. For example:
   • For Windows: cd C:\Program Files\IBM\Installation Manager\eclipse
   • For Linux: cd opt/IBM/InstallationManager/eclipse
2. On a command line, type the following command to start installation manager, substituting your own file name and location for the response file and (optionally) the log file:
   • For Windows: launcher.bat -record <response file path and name>.xml -log <log file path and name>.xml. For example, launcher.bat -record c:\mylog\responsefile.xml -log c:\mylog\record_log.xml
   • For Linux: launcher.sh -record <response file name>.xml -log <log file path and name>.xml. For example, launcher.sh -record /root/mylog/responsefile.xml -log /root/mylog/record_log.xml
3. Follow the on-screen instructions in the Install Packages wizard to make your installation choices, stopping when you reach the Summary page. For details, see Installing IBM Data Studio using the IBM Installation Manager graphical interface.
4. Click Install, and then when the installation process begins click Cancel.
5. Click Finish, then close Installation Manager.

An XML response file is created and resides in the location specified in the command.

Running Installation Manager in silent installation mode

Refer to the Installation Manager online help for additional documentation on how to run it in silent mode.

You run Installation Manager in silent mode appending the -silent argument to the Installation Manager start command launcher.bat (Windows) or launcher.sh (Linux).

• For Windows:launcher.bat -silent [arguments]
• For Linux: launcher.sh -nosplash -silent [arguments]

The following table describes the arguments used with the silent installation command:

-input

-log

To run Installation Manager in silent installation mode:

1. On a command line, change to the eclipse subdirectory in the directory where you installed Installation Manager. For example:
   • For Windows: cd C:\Program Files\IBM\Installation Manager\eclipse
   • For Linux: cd opt/IBM/InstallationManager/eclipse
2. Enter and run the following command, substituting your own locations for the response file and, optionally, the log file:
   • For Windows:. For example, launcher.bat -silent -input c:\mylog\responsefile.xml -log c:\mylog\silent_install_log.xml
   • For Linux: launcher.sh -nosplash -silent<response file name> -log <log file path and name>. For example, launcher.sh -nosplash -silent -input /root/mylog/responsefile.xml -log /root/mylog/silent_install_log.xml

Installation Manager runs in silent installation mode; it reads the response file and writes a log file to the directory you specified. While you must have a response file when running in silent installation mode, log files are optional.

Response file commands

There are two categories of commands for the response file:

• Preference commands are used to set preferences that are found in Installation Manager under File -> Preferences..., such as repository location information.
• Silent installation commands are used to emulate the Install Packages wizard in Installation Manager.

Silent install preference commands

When you define preferences in a response file, your XML code will look similar to the following example:

<preference>
	name = "the key of the preference"
	value = "the value of the preference to be set" 
</preferences>

Use the following table to identify keys and their associated values for silent installation preferences:

Silent installation commands

<profile 
id="the profile id" 
installLocation="the install location of 
the profile">
</profile>

<server>
<repository location="http:/xxx/
repository/">
<repository location="file:/C:/
repository/">
<!--add more repositories below-->
<...>
      </server>

<install>
<offering profile= "profile id" 
features= "feature ids" 
id= "offering id" version= "offering 
version"></offering>

<!--add more offerings below>
<...>

</install>

<uninstall>
<offering profile= "profile id" 
features= "feature ids" 
id= "offering id" version= "offering 
version"></offering>

<!--add more offerings below>
<...>

</uninstall>

<installALL/>

-silent -installAll 

<updateALL/>

-silent -updateAll 

Additional response file attributes

Clean mode attribute

You can apply a clean attribute in a response file so that the silent installation functionality will not preserve server and preferences settings in the user interface (UI) of Installation Manager. If you want to run in clean mode, set the following attribute to true on the opening response file tag:

<agent-input clean="true">

If you set the clean attribute to true, the silent installation will not preserve the server preference settings; these settings only take effect in the current setting. When you view the Installation Manager UI after the silent install is complete, notice that the repositories and other preferences specified in your response file are displayed on the Preferences page. These settings will not appear if you run the silent installation in clean mode.

License agreement acceptance attribute

By default, you agree to accept whatever license an installation package carries when using Installation Manager in silent installation mode. If you do not want to accept the license agreement, you can use an additional attribute in the <agent-input> element that automatically fails the silent installation operation, <agent-input acceptLicense='false">. If the installation package you are installing has a license agreement that must be accepted, the silent installation operation will fail.

Reference: Sample response file

<agent-input >

<!-- add preferences -->
<preference name="com.ibm.cic.common.core.preferences. http.proxyEnabled" 
value="c:/temp"/>

<!-- create the profile if it doesn't exist yet -->
<profile id="my_profile" installLocation="c:/temp/my_profile"></profile>

<server>
<repository location= 
"http://a.site.com/local/products/sample/20060615_1542/repository/"></repository>
/server>

<install>
	<offering profile= "my_profile" features= "core" id= "ies" 
version= "3.2.0.20060615">
	</offering>
/install>

</agent-input>

Silent install log files

The silent installation functionality creates an XML-based log file that records the result of the silent install execution (as long as a log file path is specified using -log <your log file path>.xml). If your silent installation session is successful, the log file will contain just the root element of <result> </result>. However, if errors occur during the installation, the silent install log file will contain error elements with messages such as:

<result>
	<error> Cannot find profile: profile id</error>
	<error> some other errors</error>
</result>

For detailed analysis, you can look at the logs generated in the Installation Manager data area. By using a preference command, you can optionally set the data area to your preferred location, as shown in the response file topic.

Increasing the number of file handles on Linux workstations

Important: For best results, before you work with your product, increase the number of file handles available for Data Studio, because it uses more than the default limit of 1024 file handles per process. (A system administrator might need to make this change.)

Exercise caution when using the following these steps to increase your file descriptors on Linux. Failure to follow the instructions correctly might result in a computer that will not start correctly. For best results, have your system administrator perform this procedure.

To increase your file descriptors:

1. Log in as root. If you do not have root access you will need to obtain it before continuing.
2. Change to the etc directory
3. Use the vi editor to edit the initscript file in the etc directory. If this file does not exist, type vi initscript to create it.

   Important: If you decide to increase the number of file handles, do not leave an empty initscript file on your computer. If you do so, your machine will not start up the next time that you turn it on or restart.

4. On the first line, type ulimit -n 4096 (the key here is that the number is significantly larger than 1024, the default on most Linux computers). Caution: do not set this too high, because it can seriously impact system-wide performance.
5. On the second line, type eval exec "$4".
6. Save and close the file after making sure you have done steps 4 and 5.
   Note:
   Ensure you have followed the steps correctly, as not doing this correctly will result in a machine that does not boot.
7. Optional: Restrict your users or groups by modifying the limits.conf file in the etc/security directory. Both SuSE Linux Enterprise Server (SLES) Version 9 and Red Hat Enterprise Linux Version 4.0 have this file by default. If you do not have this file, you might consider a smaller number in step 4 above (for example, 2048). You need to do this so that most users have a reasonably low limit on the number of allowable open files per process. If you used a relatively low number in step 4, it is less important to do this. However, if you choose to set a high number in step 4, refraining from establishing limits in the limits.conf file can seriously impact computer performance.

   The following is a sample limits.conf file would look that restricts all users and then sets different limits for others afterwards. This sample assumes you set descriptors to 8192 in step 4 earlier.

   *      soft nofile 1024
   *      hard nofile 2048
