This installation guide covers two independent products:
Rational Performance Tester and the
Rational Performance Tester Agent. The
Rational Performance Tester Agent is a tool that you use with
Rational Performance Tester. It is included as part of the
Rational Performance Tester product kit.
Rational Performance Tester Agent is used to automate the load and scalability testing
of server-based software applications by distributing the load generation
to other computers. With this release, the
Rational Performance Tester Agent provides support for collecting response-time breakdown
data from 64-bit application servers.
Note: Use the 64-bit Agent computer
for response-time breakdown only. Do not use the 64-bit Agent for
any other purpose.
You can use
Rational Performance Tester to ensure that your software application scales and performs
to meet service-level agreements and production-level loads. You can
increase load generation capacity by installing additional agents
on remote computers.
Depending on whether you are installing the product on 32-bit or
64-bit computers, you have different options for installing the latest
product version. An installed version of Rational Performance Tester 8.2 is a prerequisite for installing version 8.2.1. This
list explains the installation options for this release.
Note: The Rational Performance Tester workbench and Agent products are separate offerings and
must be installed separately.
For the
Rational Performance Tester workbench, review this installation information:
- If you are installing the Rational Performance Tester workbench for the first time, you must have two IBM Installation Manager for
the Rational Software Delivery
Platform repositories that are defined and selected: one for Rational Performance Tester version 8.2 and another one for Rational Performance Tester version 8.2.1. When you have both of these repositories,
you can complete a full installation of the product. This installation
scenario results in a 32-bit computer with the latest version of Rational Performance Tester workbench.
- If you are updating 32-bit computers that have the Rational Performance Tester workbench version 8.2 currently installed, use the Update function of IBM Installation Manager (using the Rational Performance Tester 8.2.1 repository) to upgrade to the Rational Performance Tester workbench version 8.2.1. This update results in a 32-bit
computer with the latest version of Rational Performance Tester workbench. See Important rollback information later in this topic.
For the
Rational Performance Tester Agent, review this installation information:
- If you are installing the Rational Performance Tester Agent for the first time, you must have two Installation
Manager repositories that are defined and selected: one for Rational Performance Tester Agent version 8.2 that contains the full media for the
8.2 release, not just the update; and another one for Rational Performance Tester Agent version 8.2.1. You can then complete a full installation
by using the version 8.2.1 repository. This installation results in
a 32-bit computer or 64-bit computer with the latest version of Rational Performance Tester Agent.
- To update 32-bit or 64-bit computers that have version 8.2 of
the Rational Performance Tester Agent installed, use the Update function of Installation
Manager (using the Rational Performance Tester Agent 8.2.1 repository) to install the 32-bit Rational Performance Tester Agent version 8.2.1. This update results in a 32-bit computer
with the latest 32-bit version of Rational Performance Tester Agent.
- To install the new 64-bit version of the Rational Performance Tester Agent on a 64-bit computer with no prior versions of the Rational Performance Tester Agent installed, you must have two Installation
Manager repositories that are defined and selected: one for Rational Performance Tester Agent version 8.2 that contains the full media for the
8.2 release, and another one for Rational Performance Tester Agent version 8.2.1. You can then complete a full installation
by using the version 8.2.1 repository. This installation results in
a 64-bit computer with the 64-bit version of the Rational Performance Tester Agent.
- To install the new 64-bit version of the Rational Performance Tester Agent on a 64-bit computer that already has a 32-bit version
of the Rational Performance Tester Agent installed, you must uninstall the Rational Performance Tester Agent, even if it is version 8.2. You must uninstall the
32-bit version because the presence of an installed version of 8.2
prevents the option of installing the 64-bit version of the 8.2.1
Agent. After you uninstall the previous Rational Performance Tester Agent, in Installation
Manager, define and select the latest version of the Agent 8.2
repository (with the full media) and the 8.2.1 repository. This installation
results in a 64-bit computer with the 64-bit version of the Rational Performance Tester Agent installed on it.
Note: To update a 32-bit Agent
(on a 64-bit computer), you do not need to uninstall the 32-bit version.
You can update it to the 8.2.1 version and still run it on your 64-bit
computer as a 32-bit Agent. There are new features for both the 32-bit
and 64-bit versions of the Rational Performance Tester Agent.
Important rollback information: To update from a version of one of the following
Rational Performance Tester releases and maintain the ability to roll back to the
earlier release, you must complete the instructions that follow:
- 8.2
- 8.2.0.1
- 8.2.0.2
- 8.2.0.4
- 8.2.0.4
- 8.2.0.5
You
must update your product to
Rational Performance Tester version 8.2.0.6 before you update to 8.2.1. For technical
reasons, you cannot roll back version 8.2.1 directly to a version
other than 8.2.0.6. If you have updated to 8.2.0.6, and then update
to 8.2.1, you can then roll back to version 8.2.0.6 and to any of
the listed versions that are prior to 8.2.0.6.
