What's New  back to top

QALoad Script Development Workbench

WWW Middleware

WWW HTML and HTTP Convert Options

QALoad has been enhanced to enable you to control how much automated processing is performed during test execution by choosing HTML mode or HTTP mode for script conversion. When going through the WWW convert for the first time, you are now prompted to choose between HTML mode and HTTP mode.

Typical HTML processing uses more processor cycles and memory during test execution, but requires less scripting.  HTTP processing instructs QALoad to disable most of its automatic HTML handling engine during replay, and it also affects how the script is generated. The HTTP mode replaces Minimized Processor mode. Scripts converted before QALoad release 5.6 using Minimized Processor mode will replay in HTTP mode.

Control of JavaScript Execution

QALoad has been enhanced so that, in HTML convert mode, you can control the level of JavaScript execution used for convert and replay. You can select from Full, Limited, or None, which result in writing the command DO_SetJavaScriptLevel (level) to the script. In HTTP mode, only the Limited level of JavaScript is executed.

QALoad Conductor

Support for Oracle Application Server Metrics

QALoad provides dynamically discovered Oracle Application Server (AS) remote extended counter categories for remote monitoring of Oracle 9i and Oracle 10g Application Server performance metrics. Each category provides counters and parameters that extend the monitoring of your Oracle AS system. The Oracle AS agent dynamically discovers all available counters and parameter values. The available categories and metrics vary by installation. The Oracle AS agent supports wild-carded parameters and resource blackouts.  

Supported platforms for Oracle AS include:

  • Solaris

  • AIX

  • HP

  • Linux

  • Microsoft Windows 2000 with Service Pack 3 or above

  • Microsoft Windows Server 2003 (32-bit)

  • Microsoft Windows XP (not all components are supported)

Oracle AS requires the following files installed on the Conductor machine:

Support for JVM Metrics

QALoad provides statically discovered categories for monitoring a Java Virtual Machine (JVM). Each category provides counters that allow the monitoring of your JVM. QALoad utilizes the Java Monitoring and Management API which were introduced in J2SE 5.0 for counter data.

QALoad uses the JMX agent. To enable and configure the JMX agent, you must set certain system properties when you start the JVM. The following is an example of the system properties set for JVM monitoring without authentication:

To turn on java authentication, set up the parameter as true.

Technical Notes  back to top

Using Microsoft Windows Vista

QALoad 5.6 provides limited support for using WWW and Winsock middlewares on the Microsoft Windows Vista platform. Limited support requires system administrator privileges and manual configuration steps to install and use the scripting, execution, and analysis capabilities of the product. Further support is scheduled for the subsequent release of QALoad and Vista-specific issues may be deferred to this release.

The use of ServerVantage Agent or ApplicationVantage Agent on the Microsoft Vista platform is not currently supported. To use these integrations, you must be running Conductor on a Windows 2000, XP, or Windows Server 2003.

If you are using QALoad on Microsoft Windows Vista, you must make the following configurations for proper operations of capturing in Winsock, performance monitoring, and Remote Monitoring for SNMP, Windows Registry:

Winsock Capture

When using the Winsock middleware with Internet Explorer 7.0 on Vista, the Enable Protected Mode setting must be disabled. This option is managed in IE7's Internet Options on the Security tab.  

WWW Capture

When using the WWW middleware with Internet Explorer 7.0 on Vista, the Enable Protected Mode setting must be disabled. This option is managed in IE7's Internet Options on the Security tab.

Performance Monitoring Group

When using any monitoring capabilities, the logged in user must be a member of the Performance Monitoring Group.

SNMP Remote Monitoring

When using SNMP monitoring, you must enable the following options:

  1. Enable SNMP feature.

  2. Enable the SNMP service.

  3. Specify an appropriate community.

  4. Assign access rights to SNMP.

  5. Enable access to SNMP through the firewall.

Windows Registry Remote Monitoring

To enable Windows Registry remote monitoring, you must start the Remote Registry service (defaults to manual startup in Vista).

Using Internet Explorer 7.0

QALoad now supports Internet Explorer 7.0. Compuware recommends that you turn off the IE 7 Anti-Phishing Filter to avoid inaccurate test results.

Capturing a Secure Site

If you are using IE 7 to capture a secure site, you may be prompted with a browser window that indicates there is a problem with the website's security certificate. To prevent the security alerts from appearing in the future and make QALoad a trusted source, follow the steps below to import a QALoad Certificate Authority into IE:

  1. Open an IE browser window and from the Tools menu, select Internet Options>Content>Certificates.
  2. In the Intended purpose drop-down list, select Client Authentication.
  3. Click Import. This starts the Welcome to the Certificate Import Wizard.
  4. Click Next, then browse for the certificate.
  5. Select the certificate, then click Next.
  6. Click Place all certificates in the following store.
  7. Click the Browse button, then select Trusted Root Certification Authorities and click Next.
  8. Click Finish.
ActiveX Codepaths and Internet Explorer 7.0

IE 7 introduced methods for gathering additional information for ActiveX controls that are missing details and lack fully defined codepaths. IE now queries Microsoft's own ActiveX repository to look for additional detail as well as other sites based on information gathered from the control.

You should decide if these additional requests are desirable for your testing scenario in QALoad and create traffic filters to reflect your preferences. You may find your test results are more consistent if you add to the Blocked Traffic filter.

Automatic Configuration of Windows Firewall on Windows XP Service Pack 2

When you install QALoad on a Windows XP machine with Service Pack 2 applied, the Windows Firewall is automatically configured to include the QALoad Player agent as an allowed exception. This configuration is required for communication between the Conductor and Player machines during a load test.

Re-Compile Scripts from Previous Versions of QALoad

If you are migrating from a previous version of QALoad, you must re-compile your existing scripts in the Script Development Workbench to use them in this release.

Do Not Use "Switch User" Windows Feature with Scripts Using NTLM Authorization

When load testing WWW scripts that use NTLM authorization, do not use the "Switch User" feature of Windows XP. Using this feature allows multiple user sessions to be active simultaneously, which can cause problems with script playback. If you need to use a different Windows profile, log off Windows and log on as a different user.

QALoad Certificate Added to certdb.txt for OFS recording

For the SSL support provided in this release, QALoad modifies the client machine's JInitiator certdb.txt file to include QALoad's CA certificate during the initial SSL recording process for an Oracle Forms Server application. This certificate authority information is internally validated by Oracle during the OFS-SSL session. If you want to remove the QALoad CA certificate, delete the following text from the certdb.txt file:




















Middleware Compiler Compatibility for SAP and Citrix

To use the SAP or Citrix middlewares, you must ensure that the VC++ MFC and Template Libraries option is selected when you install Visual C++. This option installs the headers, libraries, sources, and browser database for MFC and ATL, which are required for both the SAP and Citrix middlewares.

Large Paging File Recommended for SAP and Citrix

To prevent performance issues, Compuware recommends that you increase your system paging file size to a fixed size of:


QALoad JavaScript support requires that all form elements (for example, buttons and text fields) must be inside HTML forms in order to execute associated JavaScript. JavaScript that depends on time or date information may require the user to parameterize the script. QALoad's windowless replay does not support certain specific JavaScript functions listed below.


Citrix Waitpoints

As of 5.5.1, modified Citrix scripts should not have waitpoints placed directly after BEGIN_TRANSACTION markers. For best use of system resources, Compuware recommends that you place DO_SetTransactionCleanup before the END_TRANSACTION marker.

Retrieving ServerVantage Counter Data

The default SQL port, 1433, must be open on the ServerVantage database server so that QALoad can retrieve the counter data at the conclusion of the test.

Citrix Error Codes

In QALoad 5.6, three Citrix error codes have been added and two Citrix error codes have been modified.

New Citrix error codes are:

CTX_WARNING_00055 - The Citrix client has already disconnected, so the statement could not be executed.

CTX_ERROR_00058 - The Citrix client cannot send the key up to the specified window.

CTX_ERROR_00059 - The Citrix client was not connected, so the statement could not be executed.

Modified Citrix error codes are:

CTX_ERROR_00060 - the content has been changed to, "The Citrix client has already disconnected, so the statement could not be executed."

CTX_ERROR_00037 has been changed to CTX_ABORT_00037

Known Issues  back to top

This section describes known issues related to the current release of QALoad.

Window Not in Focus

A known issue exists with the Microsoft Operating System that may cause new programs to appear behind other already open programs. When you start a program from another program, the new program window may appear behind all other open windows. Additionally, the new-window icon flashes on the taskbar. This symptom occurs on a Microsoft Windows 2000-based computer or on a Microsoft Windows XP-based computer. Microsoft has documented a procedure that details how users can modify the value of the ForegroundLockTimeout registry entry in Registry Editor to correct the issue. For specific instructions and more information on this issue, please refer to the following article located at the Microsoft Help and Support website for details:;en-us;886217

EasyScript Issues

Internet Explorer Fails Launch When Starting Winsock Recording or Recording OFS Socket


If you are running McAfee's VirusScan 8.0 with the "Buffer Overflow Protection" option enabled, Internet Explorer may fail to launch when you start a Winsock recording or when you record OFS socket mode. To prevent this issue, disable the "Buffer Overflow Protection" feature within McAfee VirusScan.

Pop-up Blockers Need to be Disabled When Capturing in the WWW Middleware Environment

If you are running your application on Windows XP SP2, Compuware recommends you turn off the 'pop-up blocker' feature before recording a transaction. The feature can be disabled using the browser window's Tools menu in Internet Options>Privacy.

QALoad Analyze

Sending Email Messages with Test Data Using Microsoft Outlook 2003

The Send utility in Analyze does not always work properly with Outlook 2003. If you experience problems when clicking the Send button in the email that is generated by the utility, you can use the utility to create a .zip file of the results and manually attach that file to an email you create directly in Outlook.

MBCS Characters Not Supported in Analyze Tab Titles and Annotation Objects

Timing file names containing multi-byte characters do not display the file name correctly in Analyze tabs. The multi-byte characters are removed from the name and, if containing all multi-byte characters, the tab reads “TimingFile.tim”. Annotation Objects for Graphs do not support MBCS either, so some characters may be displayed incorrectly in annotation object text for languages utilizing MBCS.  

QALoad Conductor

Problem with Microsoft Office 2000 and XP

If you are using the QALoad Conductor on a machine that has Microsoft Office 2000 or XP installed, when launching Conductor, you may be prompted repeatedly to insert a Microsoft Office installation CD. This problem is a known issue with Microsoft Office. It occurs during use with an account that is different from the account used during the Office installation when none of the Office components were launched since installation. To avoid receiving the prompts, launch any Microsoft Office component under the user account that was used during installation, and close it. For more information about this Microsoft Office issue, refer to the Microsoft knowledge base article Q298385.

Other Issues

Viewing QALoad Timing Files with International Versions of Microsoft Windows

QALoad supports load testing of Traditional Chinese, Simplified Chinese, Japanese, and Korean Web applications that use Double Byte Character Sets (DBCS). Viewing timing files and Summary reports with International versions of Microsoft Windows is only possible if the timing file is viewed on the same Windows language platform on which the timing file was created.

Server Analysis Agent on a Multi-Processor Machine

When using the Server Analysis Agent to monitor the "Process->% Processor Time" counter on a multi-processor machine, values greater than 100% for any instance of the counter are reported as 100%. To ensure accurate results, Compuware recommends that you use Remote Monitoring or Top Processes Monitoring when monitoring any instance of the "Process->% Processor Time" counter.

Solaris and Logfile Generation With More Than 250 Virtual Users

A file descriptor limit exists on the Solaris platform if a script is running in threaded mode, logfile generation is turned on, and there are more than 250 virtual users. To avoid this limitation, modify the Logfile Generation parameters so that logfiles are not generated by all virtual users:

  1. On the QALoad Conductor main window, click the Script Assignment tab.
  2. In the Debug Options column for the appropriate script, click the Browse button. (Click in the Debug Options column to enable the Browse button). The Debug Options dialog box appears.
  3. On the Debug Options dialog box, in the Logfile Generation Virtual User Range area, select the Virtual User(s) option and type a range that contains less than 250 virtual users.

Administrative Rights

QALoad now supports the use of non-Administrator users on the Windows 2000 and Windows XP Professional Edition platforms. Administrative rights are still required to install the software and appropriate user privileges are required for QALoad to write files to its own directory (which by default is in the Program Files directory). Administrative rights are also required when using middlewares that require the Capture Initialization Phase option. This requirement applies to middlewares other than WWW.

Previous Version of QALoad is Detected

If you have uninstalled all previous versions of QALoad but the installation process indicates that a previous version of the product is still installed, you may need to remove a registry key. In the Windows Registry Editor, delete the following registry key if it exists on your system:


Find/Replace Functionality

The Visual Navigator's Find/Replace functionality may not find and replace XML tree items.

Checkpoint View

The Checkpoint view may be blank when applying an existing saved template.

Subrequests in Old-Style WWW Scripts

In old-style WWW scripts, additional subrequests may show up as main requests.

Invalid Characters in the Conductor Runtime Graphs on Japanese Operating System

If you are running a Japanese Operating System, you may see invalid characters in the file names in the drop-down list on the Series tab of the Conductor Runtime Graph. There is no known resolution at this time. The improper interpretation of the characters involves a third-party tool that the software uses to display this information. Check FrontLine for future updates to resolve this issue.

Central Datapool Size Limitations

There are limitations to the size of a Central Datapool that the QALoad Conductor can handle when starting a test. When attempting to use a Central Datapool file that is approximately 20MB or greater, the QALoad Conductor may fail to start. To avoid this problem, create a smaller Central Datapool file, or use a local Datapool for the test instead.

Using HTTP with the GCC Compiler on AIX after the SSL Module is Installed

HTTP scripts fail to compile on AIX systems using GCC as the compiler after the QALoad SSL module is installed. You must manually install a different library for your scripts to compile properly.

When installing the SSL module, EasyScript for Secure WWW, on AIX using the package installation method, you must perform the following steps after the installation is complete:

  1. Login to the AIX system as 'root'.

  2. cd to /opt/QALoad/lib

  3. Enter the following commands:

  1. mv libqlHTTP.a orig.libqlHTTP.a

  2. ln -s ./libqlHTTP128.a libqlHTTP.a

  3. mv libg++qlHTTP.a orig.libg++qlHTTP.a

  4. ln -s ./libg++qlHTTP128.a libg++qlHTTP.a

Data Execution Prevention

In Windows XP SP2 and Windows 2003 Server environments, if you experience problems with your applications crashing while capturing, perform the following steps:

  1. Right-click on My Computer and select Properties.

  2. Click the Advanced tab and select Settings in the Performance field.

  3. Click the Data Execution Prevention tab. By default, it is set to guard system processes. To stop your application from crashing, click the second radio button Turn on DEP for all programs and services except those I select:

  4. Add the link to your program's executable file (.exe) to the list of programs that are allowed.

  5. Restart your machine.

Using QALoad on a Windows Server 2003-based Computer

QALoad may not capture WWW content correctly, or WebProxy may intermittently fail while capturing on a Microsoft Windows Server 2003-based computer. For example, you may receive the following Application Error while capturing WWW with Microsoft Internet Explorer, "The instruction at 0xzc8224b2 referenced memory at 0x00000001. The memory could not be read."

This can occur when the Internet Explorer Enhanced Security Configuration component is enabled, which is the default state in Internet Explorer on Windows Server 2003-based computers. This can prevent certain Web sites from displaying as expected in Internet Explorer. Programs that require the browser also may not work as expected because scripts, ActiveX controls, and download capabilities are disabled.

To avoid this behavior, use the following steps to remove the Internet Explorer Enhanced Security Configuration components in Windows Server 2003:

  1. Click Start, then select Control Panel.

  2. Double click Add or Remove Programs.

  3. On the left side of the screen, select Add/Remove Windows Components.

  4. In the Components list, clear the Internet Explorer Enhanced Security Configuration check box, then click Next.

  5. Click Finish.

The Internet Explorer Enhanced Security Configuration component configures security settings that define how you browse the Internet and your corporate intranet, and helps reduce exposure of your server to Web sites that could pose a security risk. For more information about this component, refer to Enhanced Security Configuration>Internet Explorer Enhanced Security Configuration in the Internet Explorer help on your Windows Server 2003-based computer.

Clicking Page Nodes with JavaScript Content in Visual Navigator

In the Visual Navigator, when you click a Page Node that has JavaScript content that causes the same page to reopen recursively, the QALoad Workbench may disappear. This also occurs when you open the same Web page in Microsoft Internet Explorer. The C++ script that is generated compiles and executes properly, but no modifications can be made on the page in Visual Navigator. To make modifications to the C++ script, use the following steps:

  1. In the Workbench menu bar, select Visual Navigator>Create Editable Script File...

  2. In the Save As dialog box, type a name for the script file, then click Save.

  3. Edit the C++ script file.
