Notes and limitations

This section includes pre-installation notes, issues, and workarounds for LoadRunner version 12.56.

For additional limitations and workarounds, see the Troubleshooting and Limitations sections in the Help Centers.

Installation and upgrade

Virtual environments

The architectures provided by virtualization vendors are rapidly evolving. LoadRunner is expected to function as designed in these changing environments, as long as the third-party vendor guarantees full compatibility of the virtualized environment with the LoadRunner-approved hardware requirements.

If you follow the LoadRunner system requirements and support matrix to create the virtual machine, LoadRunner will work correctly.

Working on top of a virtual machine may require access to the virtualization server hardware/monitoring environment to ensure the virtualization server is not saturated; otherwise, this might obscure the virtual machine's measurements and lead to false results.

Upgrade

  • LoadRunner version 12.55 must be installed before you can install LoadRunner version 12.56.

  • Default Certificate update: The default LoadRunner certificates have been updated in 12.56. If you are not upgrading all your LoadRunner components to version 12.56, and you use the default LoadRunner certificates, you may have connection issues.

    Resolution: On an upgraded machine, copy all certificates in <LoadRunner root>\dat\cert. Paste them to the same location on all non-upgraded machines.

  • During the LoadRunner 12.56 upgrade, updated versions of the xstream and log4j JAR files are installed.

    Recommended: Manually remove the following older versions of these files, located in the <LoadRunner root>\lib folder:

    • xstream-1.4.8.jar
    • log4j-api-2.4.1.jar
    • log4j-core-2.4.1.jar

Windows

  • If you have an older version of VTS, uninstall it and reinstall the latest version from the Additional Components folder in the installation package.
  • If you have multiple LoadRunner components installed together on a machine (for example, both VuGen and Analysis, standalone versions), and you uninstall one of the components, run a Repair installation on the remaining components after the uninstall.
  • If you have VuGen standalone and BPM installed together on a single machine, and you uninstall BPM, run a Repair installation on VuGen.

Linux

  • A Red Hat Enterprise Linux (RHEL) 7 (or later) OS is required for running JavaScript Web HTTP/HTML scripts.
  • When uninstalling a load generator on a Linux machine, the uninstall process may fail and the following message may appear: "Error: failed & because &: cannot restore segment port after reloc: permission denied."
    Resolution: Use the setenforce 0 command to disable SE Linux before uninstalling the load generator. When the uninstall is complete, use the setenforce 1 command to enable SE Linux.

Coexistence with Unified Functional Testing (UFT) and UFT Pro (LeanFT)

  • It is not recommended to install LoadRunner and UFT Pro (LeanFT) on the same machine. Doing so may cause issues when invoking the Analysis API from an external code or plugin (for example, Jenkins), with recording and code generation for Java protocols, with Network Virtualization replay, TruClient functionality, and other issues. If you try to continue to work while these issues exist, it may cause LoadRunner to malfunction.

    Possible workaround: Before proceeding, make sure that LeanFT is excluded from the PATH environment variable on the machine. For more information, see this Knowledge Base article.

  • If you install or uninstall LoadRunner on a machine where UFT is installed, at the end of the process a warning message is displayed: "Cannot load resource file <somepath>/mdrv_res.e2 (<somepath>/mdrv_res.j2)." Ignore this message.

  • If you install LoadRunner and UFT on the same machine, and then uninstall one of them, the remaining software program may not function correctly.

    Resolution: Run a Repair of the software program you want to use on the machine.

  • A machine with LoadRunner and UFT, on which UFT was installed after LoadRunner, may not allow the recording of certain protocols, such as Ajax Click & Script.

    Resolution: Uninstall UFT and run a Repair on the LoadRunner installation.

  • If you install UFT on a load generator machine when the load generator agent is running, the remote Controller may not be able to run UFT scripts on the load generator machine.

    Resolution: After installing UFT, restart the load generator agent using the Agent Configuration utility, or alternatively reboot the machine.

Windows 10 (Creators Update) and Windows Server 2016 Operating Systems

General
  • When working with Windows 10 or 2016, we recommend using Internet Explorer (IE) 11 as the default browser; using the Edge browser interferes with some of the advanced functionality.

  • Use IE as the default browser with Windows 10 to prevent issues with proxy recording and certificate settings.

TruClient

  • Where applicable, we recommend using TruClient Firefox or Chromium on Windows 10 and Windows 2016.
  • (Windows 10 + IE) TruClient script conversion to Web - HTTP/HTML is not supported on Windows 10 using the IE browser.
  • (IE) The TruClient IE cache simulation mechanism is not supported on load generators running on Windows OS systems installed with KB3000850, Windows 10, or Windows Server 2016. As a result, when running TruClient scripts in IE on a load generator with one of these operating systems, the browser’s cache may not function as expected. This may cause inconsistent server load and measurements.

    Resolution: Remove Microsoft KB3000850 (not relevant for Windows 10 or Windows 2016).

Web

(Windows 10 + IE) WinINet recording mode is not supported on Windows 10. An empty script will be generated.

RDP

  • When recording mstsc.exe on Windows 10, if the RDP server side enables FIPS, the default recording will produce the following error: "Because of an error in data encryption, this session will end. Please try connecting to the remote computer again."

    Resolution: Turn off FIPS on the server side, or perform the following procedure to enable recording using the SSL mode:

    1. Open mstsc, enter the IP address of the RDP server, click Show Options to expand the dialog box, and then click Save As to save the configuration to a file. Name the file RDPConfig.RDP.
    2. Open RDPConfig.RDP with Notepad, add enablecredsspsupport:i:0 at the bottom. Search for authentication level in the same file, make sure this line is authentication level:i:2.
    3. Go to <LoadRunner root>\dat\, open rdp_ro.ini with Wordpad or Notepad++ (do not use Notepad because of the new line characters issue), add SupportSSL=1 at the bottom.
    4. In VuGen, click Start Recording. In the Remote Desktop Connection dialog box, click Show Options. Click Open, and choose the RDPConfig.RDP file that you saved above. Then click Connect.

Protocols not supported

The following protocols are currently not supported on Windows 10 or Windows 2016:

  • RTE (Remote Terminal Emulator)

  • SAP GUI

  • Ajax - Click and Script: Replay is supported, Recording is not supported
