The IBM Rational Performance Tester Agent Controller is a tool for automating the load and scalability testing of server-based software applications. You can use Rational Performance Tester to ensure your software application will scale and perform to meet service-level agreements and production-level loads. You can increase load generation capacity by installing additional agents on remote computers. It is included as part of the IBM Rational Performance Tester product kit.

Installation overview

Installation conventions and terminology

Understanding these terms and conventions can help you take full advantage of the installation information and your product.

The following conventions are used in this installation information:

These terms are used in the installation topics.

Installation directory
The location of product artifacts after the package is installed.
Package
An installable unit of a software product. Software product packages are separately installable units that can operate independently from other packages of that software product.
Package group
A package group is a directory in which different product packages share resources with other packages in the same group. When you install a package using Installation Manager, you can create a new package group or install the packages into an existing package group. (Some packages cannot share a package group, in which case the option to use an existing package group is unavailable.)
Repository
A storage area where packages are available for download. A repository can be disc media, a folder on a local hard disk, or a server or Web location.
Shared directory
In some instances, product packages can share resources. These resources are located in a directory that the packages share.

Planning the installation

Read all the topics in this section before you begin to install or update any of the features of your product. Effective planning and an understanding of the key aspects of the installation process can help ensure a successful installation.

Installation Manager overview

IBM Installation Manager is a program for installing, updating, and modifying packages. It helps you to manage the IBM applications, or packages, that it installs on your computer. Installation Manager also helps you to keep track of what you have installed, determine what is available for you to install, and to organize installation directories.

Installation Manager provides tools that help you keep packages up to date, modify packages, manage the licenses for your packages, and uninstall packages.

Installation Manager includes six wizards that make it easy to maintain packages:

Software requirements for extending an installed Eclipse IDE

The products in this version of the IBM Rational Software Delivery Platform were developed for use with version 3.4, or later, of the Eclipse integrated development environment (IDE). You can only extend an existing Eclipse IDE of version 3.4 with latest updates from eclipse.org.

To extend an installed Eclipse IDE, you also require a Java runtime environment from one of these Java development kits:

Note:
You might need to update your Eclipse version in order to install updates to Rational Performance Tester. Refer to the release documentation of the update for information on changes to the prerequisite Eclipse version.

Supported virtualization software

Rational Performance Tester supports Citrix Presentation Manager Version 4 or 4.5, running on Windows Server 2003 Standard Edition or Windows Server 2003 Professional Edition. Although the client for Citrix Presentation Server is available on Linux, Rational Performance Tester does not support the Citrix extension on Linux.

Additional software requirements

User privileges requirements

You must have a user ID that meets the following requirements to installRational Performance Tester, Rational Service Tester, Rational Performance Tester Agent Controller.

Installation considerations

Part of planning entails making decisions about installation locations, working with other applications, extending Eclipse, upgrading, migrating, and configuring help content.

Installation locations

IBM Installation Manager retrieves product packages from specified repositories and installs the products into selected locations, referred to as package groups.

Package groups

During installation, you specify a package group into which to install a product.

Important:
When installing products on the Windows Vista operating system, do not create package groups in the Program Files directory (C:\Program Files\). Otherwise, users without Administrator privileges will be unable to use the product.

Shared resources directory

The shared resources directory is where product resources are installed so that they can be used by multiple product package groups. You define the shared resources directory the first time that you install the first product package. For best results, use your largest disk drive for shared resources directories. You cannot change the directory location unless you uninstall all product packages.

Important:
When installing products on the Windows Vista operating system, do not create the shared resources directory in the Program Files directory (C:\Program Files\). Otherwise, users without Administrator privileges will be unable to use the product.

Coexistence

Some products are designed to coexist and share functions when they are installed in the same package group. A package group is a location where you can install one or more software product packages.

Offering coexistence considerations

When you install each product package, you select whether you want to install the product package into an existing package group or whether you want to create a new package group. IBM Installation Manager blocks products that are not designed to share or do not meet version compatibility and other requirements. If you want to install more than one product at a time, the products must be able to share a package group.

Any number of eligible products can be installed to a package group. When a product is installed, the product functions are shared with all of the other products in the package group. If you install a development product and a testing product into one package group, when you start either of the products, you have both the development and testing functions available to you in your user interface. If you add a product with modeling tools, all of the products in the package group will have the development, testing, and modeling functionality available.

Installing with your Eclipse instance

The product package that you install using IBM Installation Manager comes with a version of Eclipse, which is the base platform of this product package. If you already have Eclipse installed on your workstation, you can add your product package directly to that Eclipse installation and extend the functions of the Eclipse integrated development environment (IDE).

Extending an Eclipse IDE adds the functions of the newly installed product, but maintains your IDE preferences and settings. Previously installed plug-ins are also still available.

In most cases, your current Eclipse IDE must be the same version as the Eclipse that the product you are installing uses. Installation Manager checks that the Eclipse instance that you specify meets the requirements for the installation package and helps you install the latest updates from eclipse.org, if necessary.

Important:
When installing products on the Windows Vista operating system, do not install Eclipse in the Program Files directory (C:\Program Files\). Otherwise, users without Administrator privileges will be unable to use the product.

Extending an existing Eclipse IDE

When you install the your product package or packages, you can choose to extend an Eclipse integrated development environment (IDE) already installed on your computer by adding to the functions that your new product or products contain.

Any product package that you install using 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 it, that is, add to the IDE the additional functionality provided in the product package or packages.

To extend an 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 a product package, but you also want to have the preferences and settings in your current IDE when you work with the functionality from the product package. You also might want to work with plug-ins that you have installed that already extend the Eclipse IDE.

Your existing Eclipse IDE must be version 3.4 for the latest updates from eclipse.org to be extended. Installation Manager checks that the Eclipse instance you specify meets the requirements for the installation package.

Note:
You might need to update your Eclipse version in order to install updates for some products. Refer to the update release documentation for information on changes to the prerequisite Eclipse version.

Increasing the number of file handles on Linux workstations

For best product performance, increase the number of file handles above the default of 1024 handles.

Important:
Before you work with your Rational product, increase the number of file handles. Most Rational products use 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 steps to increase your file descriptors on Linux. If the instructions are not followed correctly, the computer might not start correctly.

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
    Attention: If you decide to increase the number of file handles in the next step, do not leave an empty initscript file on your computer. If you do so, your computer will not start up the next time that you turn it on or restart.
  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.
  4. On the first line, type ulimit -n 4096. The point is that 4096 is significantly larger than 1024, the default on most Linux computers.
    Important:
    Do not set the number of handles too high, because doing so can negatively impact system-wide performance.
  5. On the second line, type eval exec "$4".
  6. Save and close the file after making sure you have completed steps 4 and 5.
    Note:
    Ensure that you follow the steps correctly. If this procedure is not completed correctly, your computer will not start.
  7. Optional: Restrict the number of handles available to 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, consider using a smaller number in step 4 in the previous procedure (for example, 2048). Do this so that most users have a reasonably low limit on the number of open files that are allowed per process. If you use a relatively low number in step 4, it is less important to do this. However, if you set a high number in step 4 earlier and you do not establish limits in the limits.conf file, computer performance can be significantly reduced.

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

    *      soft nofile 1024
    *      hard nofile 2048
    root    soft nofile 4096
    root    hard nofile 8192
    user1   soft nofile 2048
    user1 hard nofile 2048

    Note that the * in the preceding example sets the limits for all users first. These limits are lower than the limits that follow. The root user has a higher number of allowable handles open, while number available to user1 is between the two. Make sure that you read and understand the documentation contained in the limits.conf file before making changes.

For more information on the ulimit command, see the man page for ulimit.

Install the product software

These instructions can be used to install the Rational Performance Tester, the Rational Service Tester, and the Rational Service Tester Agent Controller.

By starting the installation process from the launchpad program, IBM Installation Manager is automatically installed if it is not already on your computer, and it starts preconfigured with the location of the repository that contains the product package. If you install and start IBM Installation Manager directly, then you must set repository preferences manually.

To install from the launchpad:

Important:
Installation notes for the Windows Vista operation system:
  1. Review the Installation considerations, if you have not done so already.
  2. If you are installing from compressed files, such as ZIP or ISO files, unpack the files into a common directory. For product installations with multiple disks, the uncompressed directories must read /disk1,/disk2, and so forth.
  3. If you are installing from a CD, insert the first product disc into your CD drive. If autorun is enabled on your workstation, then the launchpad will start autostart. Otherwise, start the launchpad program manually.
  4. Select a language in which to run the launchpad and Installation Manager. Click OK.

Only recommended updates are displayed by default.
  8. Select the product package and any updates to the package that you want to install. Updates that have dependencies are automatically selected and cleared together. Click Next to continue.
    Note:
    If you install multiple packages at the same time, then all the packages will be installed into the same package group.
  9. On the Licenses page, read the license agreement for the selected package. If you selected more than one package to install, there might be a license agreement for each package. On the left side of the License page, click each package version to display its license agreement. The package versions that you selected to install (for example, the base package and an update) are listed under the package name.
    1. If you agree to the terms of all of the license agreements, click I accept the terms of the license agreements.
    2. Click Next to continue.
  10. On the Location page, type the path for the shared resources directory in the Shared Resources Directory field, or accept the default path. The shared resources directory contains resources that can be shared by one or more package groups. Click Next to continue.

    The default path is:

    Important:
    You can specify the shared resources directory only the first time that you install a package. Use your largest disk for this to help ensure adequate space for the shared resources of future packages. You cannot change the directory location unless you uninstall all packages.
  11. On the Location page, create a package group to install the product package into or if this is an update, use the existing package group. A package group represents a directory in which packages share resources with other packages in the same group. To create a new package group:
    1. Click Create a new package group.
    2. Type the path for the installation directory for the package group. The name for the package group is created automatically.

      The default path is:

      • For Windows. C:\Program Files\IBM\SDP
      • For Linux. /opt/IBM/SDP
    3. Click Next to continue.
  12. On the next Location page, you can choose to extend an existing Eclipse IDE already installed on your system, adding the functionality in the packages that you are installing. You must have Eclipse Version 3.4 with the latest updates from eclipse.org to select this option.
  13. On the Features page under Languages, select the languages for the package group. The corresponding national language translations for the user interface and documentation for the product package will be installed.
  14. On the next Features page, select the package features that you want to install.
    1. Optional: To see the dependency relationships between features, select Show Dependencies.
    2. Optional: Click a feature to view its brief description under Details.
    3. Select or clear features in the packages. Installation Manager will automatically enforce any dependencies with other features and display updated download size and disk space requirements for the installation.
    4. Optional: If you plan to collect response time breakdown data, select the IBM Rational Performance Tester Agent check box.
    5. When you are finished selecting features, click Next to continue.
  15. On the Summary page, review your choices before installing the product package. If you want to change the choices that you made on previous pages, click Back and make your changes. When you are satisfied with your installation choices, click Install to install the package. A progress indicator shows the percentage of the installation completed.
  16. When the installation process is complete, a message confirms the success of the process.
    1. Click View log file to open the installation log file for the current session in a new window. You must close the Installation Log window to continue.
    2. In the Install Package wizard, select whether you want the product to start when you exit.
    3. Click Finish to launch the selected package. The Install Package wizard closes and you are returned to the Start page of Installation Manager.
  17. If the Data Collection Infrastructure software is installed, follow these steps to enable the test server for data collection:
    1. From the Start menu, select IBM Software Delivery Platform -> IBM Rational Data Collection Infrastructure -> Application Server Instrumenter to open the instrumentation application.
    2. Click the Add Local button and select the type of application server that you have running on the server.
    3. Fill in the server type specific fields including the location of the server if required and click OK.
    4. Stop and start the server for the instrumentation to take effect.
    5. From the Start menu, select IBM Software Delivery Platform -> IBM Rational Data Collection Infrastructure -> Start Data Collection.
    Note:
    All Rational Performance Tester systems involved with the Data Collection Infrastructure must have the data collection software running for the transaction breakdown functionality to be available within the results of an Rational Performance Tester test schedule.
    Note:
    The Application Server Instrumenter or the instrumentServer.bat (or instrumentServer.sh) batch file can fail with a generic error message ("Error during install/uninstall") when instrumenting or uninstrumenting a server. If this occurs, you can find more information to help troubleshoot the error in the log files in the IBM Tivoli(R) common directory. On Windows, the default location of this directory is C:\Program Files\IBM\tivoli\common. On Linux, the default location of this directory is /var/ibm/tivoli/common. If the IBM Tivoli common directory is not in the default location, search for a path containing tivoli/common, or for any of these log files: trace-install.log, trace-ma.log, or trace-tapmagent.log.
    Note:
    For Websphere Application Server 6.x, if you create a new profile and then use the Application Server Instrumenter to instrument this profile without first starting WebSphere(R) Application Server, the Application Server Instrumenter will report that the server is instrumented and will request that you re-start the server manually. This message is incorrect; the server is not actually instrumented. To work around this problem:
    1. Close and then re-start Application Server Instrumenter.
    2. Select the entry you just added from the list of instrumented servers and click Remove.
    3. Re-start WebSphere Application Server.
    4. Re-start Application Server Instrumenter and use it to instrument the server.
    To avoid this problem, after creating a new profile, start the WebSphere Application Server profile manually. Then, use the Application Server Instrumenter to instrument the server.
  18. License the product.

Manage licenses

Licensing for your installed IBM software and customized packages is administered using the Manage Licenses wizard in the IBM Installation Manager. The Manage Licenses wizard displays license information for each of your installed packages.

Using the Manage Licenses wizard, you can apply a license to a product or upgrade trial versions of an offering to a licensed version by importing a product activation kit. You can also enable Floating license enforcement for offerings with trial or permanent licenses to use floating license keys from a license server.

For more information on managing licenses for your Rational product, see:

Licenses

As a purchaser of an IBM Rational software product, you can choose from three types of product licenses: an Authorized User license, an Authorized User Fixed Term License (FTL), and a Floating license. The best choice for your organization depends upon how many people use the product, how often they require access, and how you prefer to purchase your software.

Authorized User license

An IBM Rational Authorized User license authorizes a single individual to use a Rational software product. Purchasers must obtain an Authorized User license for each individual user who accesses the product in any manner. An Authorized User license cannot be reassigned unless the purchaser replaces the original assignee on a long-term or permanent basis.

For example, if you purchase one Authorized User license, you can assign that license to one individual, who can use the Rational software product exclusively. The Authorized User license does not authorize a second individual to use that product at any time, even if the licensed individual is not using the product.

Authorized User Fixed Term License

An IBM Rational Authorized User Fixed Term License (FTL) authorizes a single individual to use a Rational software product for a specific length of time (the term). Purchasers must obtain an Authorized User FTL for each individual user who accesses the product in any manner. An Authorized User FTL cannot be reassigned unless the purchaser replaces the original assignee on a long-term or permanent basis.

Note:
When you purchase an Authorized User FTL under the Passport Advantage(R) Express(TM) program, IBM will automatically extend the license term for an additional year at the prevailing price unless you notify IBM before the license expires that you do not want an extension. The subsequent FTL term starts when the initial FTL term expires. The price for this subsequent term is currently 80% of the initial FTL price, but is subject to change.

If you notify IBM that you do not want to extend the license term, then you must stop using the product when the license expires.

Floating license

An IBM Rational Floating license is a license for a single software product that can be shared among multiple team members; however, the total number of concurrent users cannot exceed the number of floating licenses you purchase. For example, if you purchase one floating license for a Rational software product, then any user in your organization may use the product at any given time. Another person who wants to access the product must wait until the current user logs off.

To use floating licenses, you must obtain floating license keys and install them on a Rational License Server. The server responds to user requests for access to the license keys; it will grant access to the number of concurrent users that equals the number of licenses the organization purchased.

License enablement

If you are installing the software for the first time or want to extend a license to continue using the product, you have options on how to enable licensing for your product.

Licenses for this product are enabled in two ways:

Activation kits

The Product Activation Kit CD contain the permanent license key for you product. You use IBM Installation Manager to import the activation kit to your product.

Floating license enforcement

Optionally, you can obtain floating license keys, install IBM Rational License Server, and enable Floating license enforcement for your product. Floating license enforcement provides the following benefits:

Note:
Some 7.0 and later versions of Rational products require an upgraded version of the Rational License Server. See support article http://www.ibm.com/support/docview.wss?uid=swg21250404 for license upgrade information.

For more information on obtaining activation kits and Floating licenses, see Purchasing licenses.

Purchasing licenses

You can purchase new licenses if your current product license is about to expire or if you want to acquire additional product licenses for team members.

To purchase licenses and use your product, complete the following steps:

  1. Determine the type of license you want to purchase.
  2. Go to ibm.com(R) or contact your IBM sales representative to purchase the product license. For details, visit the IBM Web page on How to buy software.
  3. Depending on the type of license you purchase, use the Proof of Entitlement that you receive and do one of the following to enable your product:

When you want to import the activation kit or enable Floating License support for your product, use the Manage Licenses wizard in IBM Installation Manager.

Viewing license information for installed packages

You can review license information for your installed packages, including license types and expiration dates, from IBM Installation Manager.

To view license information:

  1. Start IBM Installation Manager.
  2. On the main page, click Manage Licenses.

The package vendor, current license types, and expiration dates are displayed for each installed package.
