Release Notes - IBM Rational Performance Tester, Version 9.0.1

This document contains information about the known limitations and problems for IBM® Rational® Performance Tester.

Description

Rational Performance Tester is a scripting-free environment for automating load and scalability testing of web, ERP, and server-based software applications. Rational Performance Tester provides rich and customizable reporting to help you identify the presence and cause of system bottlenecks. It captures the network traffic that is rendered when the application under test interacts with a server. This network traffic is then emulated on multiple virtual users while playing back the test. With Rational Performance Tester, you can test applications that use the following protocols or domains:
  • HTTP
  • SAP (GUI)
  • Citrix
  • Socket
  • TN3270
  • Service (SOA)
To scale up the load for tests without investing money in computers, you can create a schedule that runs in a cloud location. You can specify the number of agents require for a run. The cost of the cloud run is based on the number of virtual users and the number of hours.

The information in this file applies to IBM Rational Performance Tester.

Note: Translated versions of this file are also available in the Rational Performance Tester Knowledge Center.

What's new in version 9.0.1

  • Web Analytics reports are now set as the default reports.
  • Support to view performance reports for different geographies or agent locations. See Comparing results from various geographies or agent locations.
  • Support to specify transaction rate at which all the virtual users in a user group should run in parallel for a given time period. See Creating rate generators in user groups.
  • Support to record a test on a server that supports Server Name Indication TLS protocol by using the HTTP test extension. See Working with SNI recordings.
  • Support to compare multiple runs in the HTML format. See Exporting reports to HTML format.
  • Support to export multiple time ranges within a run in the CSV format. See Exporting results to a CSV file.
  • Support to export results in the decompressed mode(folder).
  • The Executive Summary, Importing Response Time Breakdown Data, and Import Resource Monitoring Data options for performance report is available only with the legacy report. To use this option, ensure that you add -DltStats=1 entry in the eclipse.ini file, start workbench, and run the test.
  • Support for the Protocol Data view now in cloud runs.
  • Support to run SAP Web test on the cloud.
  • Support to run long duration SAP tests by using an external process that can be set to start at the schedule, user group, or virtual user's level. See Running a long run mode SAP GUI test.
  • Support to provide user authentication for JMS MQ configuration.
  • Ability to record and run tests for the HTTP/2 protocol is in Beta and is not intended for production use. To test the feature add a certain flag to the eclipse.ini file that is located at the product installation directory. For information about the flag and other dependencies, see Preparing to record a test for HTTP\2 protocol.
