Ajax TruClient - An advanced protocol for modern JavaScript based
applications (including Ajax) emulating user activity within a web
browser. Scripts are developed interactively in Mozilla Firefox.
Silverlight - A new protocol for Silverlight based applications
emulating user activity at the transport level. Allows generating high
level scripts by automatically importing and configuring WSDL files
used by the application.
Java over HTTP - A new protocol designed to record java-based
applications and applets. It produces a Java language script using
web functions. This protocol is distinguished from other Java
protocols in that it can record and replay Java remote calls over
HTTP.
Citrix
 The Citrix Protocol now supports Citrix Online Plugin versions
11.2 and 12.0.
 Added support for Citrix XenApp Server 5.0
Oracle NCA - NCA Java object property support now provides
automated creation and registration within a script of a queryanswer table of communication between client-side Java objects and
the Oracle NCA server.
SAPGUI - Added support for SAPGUI for Windows Client version
7.20.
Service Test - The LoadRunner Controller can run scripts created in
HP Service Test 11.00, HP's solution for creating and running
automated tests for SOA and headless technologies. Refer to the
Service Test documentation for details of creating Service Test
scripts for a load testing scenario.
Features

Data Format Extension (DFE) - Enhanced data format capabilities
for the Web (HTTP/HTML) protocol family. Allows converting raw
HTTP traffic into a maintainable and structured XML format and
enables correlations by XPATH.

Correlation Studio - Web (HTTP/HTML) automatic correlation
mechanism has been enhanced to search for possible correlations in
the larger scope of snapshot data created during code generation
including data formatted by DFE.
Snapshot View - New snapshot view for Web (HTTP/HTML)
protocol steps allows viewing complete HTTP traffic in both raw and
DFE generated formats.
VuGen - HP ALM Integration - Enhanced integration with HP
Application Lifecycle Management platform that serves also Quality
Center and Performance Center editions.
Windows Support - Added support for Windows 7 and Windows
Server 2008. See below for limitations.
Analysis Reports - Enhanced Analysis reports are more
customizable. Analysis data can be exported to a variety of formats,
including Word, Excel, PDF, and HTML. New report templates allow
saving report definitions and generating reports based on a
template.


Diagnostics for J2EE/.NET Requirements
ContentCheck in Multilingual Environments
Windows Firewall Considerations
WAN Emulation
HP Performance Validation SDK
Windows



On Vista machines, if you want to add a new license from the
LoadRunner Launcher (Configuration > LoadRunner License > New
License), you need to have Administrator privileges on the Vista
machine.
If you are running McAfee or Aladdin's eSafe anti-virus applications,
close them before installing LoadRunner.
To use Windows 2003 with a HASP plug, download Aladdin's latest
HASP driver.
UNIX


The LoadRunner UNIX installation is based on native packages per
operating system. This requires you to be logged in as root user to
run the installation.
If you are installing a UNIX load generator on an HP-UX operating
system, you cannot install it from a network location. You can install
it directly from the installation disk or you can copy the installer onto
the local directory of the target machine.
Virtual Environment Installation


LoadRunner supports Vmware version ESX 3.0, ESX 3.5, and VM
Workstation 5.5 and is certified for the following Windows platforms:
Windows XP SP2/SP3, Windows Server 2003 SP2, and Windows
Vista SP1.
Running Vusers on virtual machines may adversely affect
performance due to the sharing of physical resources.
Diagnostics for J2EE/.NET Requirements
A unique transaction name must be used for each scenario.
ContentCheck in Multilingual Environments
This version supports ContentCheck rules in French, German, Spanish,
and Italian. The correct language file should be installed according to
the system locale.
The suitable language file can also be copied from the installation disk:
..\lrunner\MSI\setup\international\<lang>\dat\LrwiAedInstall
ation.xml
to the <LoadRunner>\dat directory.
Windows Firewall Considerations
In most Windows environments, Windows Firewall is turned on by
default. The firewall does not allow certain LoadRunner components to
communicate with each other. The Windows firewall therefore needs to
be turned off.
Note: Turning off Windows Firewall increases the risk to your computer's
security.
For each process that needs the firewall you can unblock the process by
clicking the unblock button in the popup window that indicates that the
program needs it, or by manually tuning the Windows firewall from the
Exceptions tab.
WAN Emulation


Make sure that the relevant 3rd party components are installed on
the load generator machines. Note that in addition to the load
generators, you may be required to install the relevant 3rd party
component on additional LoadRunner components. For more
information, see the relevant 3rd party software installation
documentation.
The relevant 3rd party component licenses must be purchased from
the 3rd party vendor and not from HP.
HP Performance Validation SDK
HP Performance Validation SDK version 11.00 can be used only with
LoadRunner version 11.00 and above.

General

To run LoadRunner on Windows 7 or Window Server 2008, you must
have Administrator privileges and User Account Control (UAC) must
be disabled.
 Internet Explorer 8
 For Click and Script based protocols, address bar operations and
pop-up windows are not supported.
 The Internet Explorer SmartScreen Filter must be disabled when
recording with Citrix Web Access (formerly known as Citrix
NFuse).
 Internet Explorer Enhanced Security Configuration should be
disabled when recording with Citrix Web Access (formerly known as
Citrix NFuse) recording on Windows 2003/2008 Server.
 WinInet recording is not supported.







Recording on 64 bit machines is not supported, however replaying
scripts on 64 bit machines is supported.
FTP active mode with SSL is not supported in both explicit and
implicit flavors.
The network speed simulation settings in the Network: Speed
Simulation node in the Run Time Settings do not work with
Windows 7. Virtual users will use the maximum bandwidth
regardless of which option was selected.
It is not recommended to install and uninstall a Load Generator
standalone installation on the same machine with a VuGen
standalone installation.
The Load Generator cannot run Citrix scripts in service mode when
the script was recording using Citrix Client version is 11.2 or higher.
The Agent icon does not appear in Windows 2008 and Vista when
the LoadRunner Agent service is launched.
When LoadRunner Agent runs as service (magentservice.exe),
files that are stored on remote network drives or referred to by UNC
path cannot be accessed (script, parameter file, etc.). If you want to
access files this way, run the LoadRunner Agent as process
(magentproc.exe). If this is not possible, please contact Customer
Support.
VuGen


SAP (Click and Script) recording. During recording, if you use a
keyboard option instead of a UI element (for example, pressing
ENTER instead of clicking the log on button), the step may not be
recorded. In general, when recording your script, it is recommended
to use UI elements rather than keyboard options.
Citrix snapshots. Black snapshots may appear during record or
replay when using Citrix Presentation Server 4.0 and 4.5 (before
Rollup Pack 3).
Possible workaround: On the Citrix server select Start Menu >
Settings > Control Panel > Administrative Tools > Terminal
Services Configuration > Server Settings > Licensing and
change the setting Per User or Per Device to the alternative setting
(i.e. If it is set to Per User, change it to Per Device and vice versa.)

Recording Window Size and XenApp Plugin for Hosted
Applications 11. The recording window size options does not work
properly with the XenApp Plugin for Hosted Applications 11. The size
of the client window is installed, but the server screen resolution is
not. This is a Citrix Client bug and will be fixed in future Citrix Client
versions.
Workaround: When recording, set the window size equal to the
local screen resolution. When replaying/load testing, set the VuGen
or Load Generator's screen resolution to equal the resolution used
when the script was recorded. To verify the recorded resolution, view
the Window property in the <Script Folder>\default.cfg file.

For the following protocols, replay is supported but recording is no
longer supported: Siebel DB2, Siebel MSSQL, Siebel Oracle, and
Voice XML.






In Test Result reports, you can only use the Export to HTML file
utility for scripts replayed in version 9.50 and later. To generate an
HTML report for scripts created with earlier versions, run the script
again in the 9.50 version (or later) of the product.
If you terminated the Protocol Advisor immediately after the
detection process started, the Protocol Advisor may leave a zombie
process of the detected application, causing all recordings and
detection sessions that follow to fail. Workaround: Manually
terminate the zombie process.
The new Web snapshot model is backward compatible with previous
versions of LoadRunner, however some snapshot data may be
missing. If this occurs, regenerate the script.
The JSON Data Format Extension does not work in UNIX
environments.
Recording a network based application on Windows 7. To
record a network-based application (including Web), IPv6
communication must be disabled. Follow the instructions in
http://www.addictivetips.com/windows-tips/how-to-disableipv6-in-windows-7/ to disable IPv6 in Windows 7.
For protocols using XML, replay fails to create a request when a
parameterized input argument contains the ampersand (&)
character.
Correlation Studio


In VuGen, when correlating large amount of snapshot data, in some
cases the parameter is not created and data is not correlated.
Scan for correlation will work on a script that was regenerated and
replayed with the early access version.
VuGen Protocols
AJAX (Click and Script)

ActiveX objects and Java applets are only supported on Windows
platforms.
Ajax TruClient


The Ajax TruClient protocol can only be used with applications that
support the Mozilla Firefox browser.
Documentation and further limitations about this protocol will be
provided separately.
Citrix


Installation of the registry patch is required for the support of all
version of Citrix clients over 10.x. Additionally, you need to install
Enable_Citrix_API.reg from the LoadRunner\dat folder on
Vugen or LG machines if a Citrix Client will be installed after
installing LoadRunner.
Running Citrix Vusers on virtual machines may adversely affect
performance due to the sharing of physical resources.


Citrix XenApp Desktop cannot be recorded with Citrix Web Access
(formerly known as Citrix NFuse) if Desktop View (Desktop Toolbar)
is enabled.
Citrix Agent text trapping does not work on Citrix servers installed
on Windows Server 2008.
Click and Script (All)











Does not support VBScript
Does not support user actions on ActiveX objects and Macromedia
Flash
Scalability is lower than the Web HTML protocol, depending on the
size and functionality of the business process
Replay snapshots may differ from the actual Web page
Support of right-to-left languages is limited (e.g., bi-directional or
reversed text may not be processed as expected). This is defined by
the default operating system translation table.
Recording of an application in a specific language (e.g., French,
Japanese) must be performed in a machine whose default locale (in
Settings > Control Panel > Regional Options) is the same
language
The locale of the load-generator machine, including the default nonUnicode character set, must be configured to be the same as that of
the recording machine. It cannot be assumed that the UNIX default
character set is the same as in Windows, even for US-English
machines, and this has to be explicitly verified. For example, the
default character set in some UNIX machines, such as Linux, is UTF8.
The Recording Options dialog box may take a long time to open.
Citrix Clients 11.2 and higher do not support the TCP/IP mode in the
Citrix > Login node of the Recording Options dialog box.
When recording Citrix Web Access (formerly known as Citrix NFuse)
applications, set the window size to "No preference" in the Citrix
XenApp web portal preferences page.
Web (Click and Script) no longer supports replay of Applets and
ActiveX objects. This functionality is now part of the AJAX (Click and
Script) protocol.
Java (All)


Java Record Replay Protocol: Recording of JMS applications requires
JDK version 1.6u17 or lower.
Java over HTTP Protocol: Requires the JDK version 1.5 or higher.
Listing Directory Service (LDAP)


If an LDAP version 3 script fails during replay, modify the
mldpa_logon_ex statement to specify the version number by
adding "Version=3" after "URL=.."
When recording LDAP scripts, the binary parameter values for
certain LDAP functions (such as mldap_add or mldap_modify) are
not recorded. Recording of binary parameters is part of the
protocol's extended functionality and is not supported by VuGen.
Media Player (MMS)
Media Player scripts fail with the error: Error -86801:Host access
denied, <hostname> not available or missing.
Workaround: Call the mms_disable_host_check function in all
Media Player scripts.
Microsoft .NET


When the application under test retrieves a server-activated object
by calling new RemoteObject(), VuGen generates a
RemotingServices.Connect function.
Applications using multiple processes or multiple application domains
are only partially supported.
Microsoft Remote Desktop Protocol (RDP)



Clipboard sharing supports only short simple textual content.
When recording with RDP Agent, applications which were developed
using CBuilder may not record properly.
RDP 6.1 is not supported in Windows 7, Windows Server 2008,
Windows Vista SP1 and Windows XP SP3.
SAP (Click and Script)






Cannot define transactions to measure time of a subset of steps
done in a modal dialog.
During recording, if a user double-clicks on a tree-view tree cell
outside of its text, VuGen records "Select" instead of "Activate." This
results in a missing POST in replay.
If the list of retrieved values contains a scroll bar, cannot select an
item that requires scrolling in order to get it from the server.
Scalability is lower than the SAP Web protocol, depending on the
size and functionality of the business process.
Does not support the Replace with Alternate Navigation runtime setting.
In certain SAP environments (such as 6.20 and 6.40), the replay
fails for tests that call the web_element function and select an
element whose tag name is "TD".
SAPGUI

Due to a SAP-related bug, do not use the
sapgui_tree_set_column_order API function in LoadRunner
version 9.5.
Silverlight




REST services do not generate Silverlight service calls however they
can be recorded and replayed.
You cannot edit the WSDL location in the Protocol and Security
Scenario dialog box.
The Update button in Silverlight Service node of the Recording
Options dialog box is not working (always reporting success).
Duplex (Polling) Binding for WCF Web Services is not supported.



Silverlight 4 Client is supported, however applications developed
using the new communication features such as net.tcp binding are
not supported.
VuGen snapshot viewer does not support Silverlight controls.
The Silverlight Protocol does not support applications which use
Japanese, Korean, Simplified Chinese, and Traditional Chinese.
WAP


Cannot record in secure mode. Workaround: Record script in nonsecure mode and then replay it in secured mode.
Cannot replay a script in connection-less mode.
Web Services













In VuGen Tree view, you may experience problems viewing/editing
the following types of elements: any_object, CDATA, derived and
recursive.
For large SOAP envelopes, Record and Replay snapshots are
disabled.
The Import SOAP feature is not supported for envelopes containing
a single element larger than 500KB.
The recording of requests with attachments or security is not
supported.
For Axis toolkit, Web service calls that include both attachments and
security are not supported.
For .NET toolkit, SOAP version 1.2 is not supported for asynchronous
calls.
You can enter text strings up to 10 KB to encode to base 64. If your
string is larger, use the Get from file option.
For Axis toolkit, to use base64Binary encoding in scripts created
before version 9.10, you must update your WSDL.
VuGen supports Web Service messages over JMS message Queue,
but does not support JMS Topics.
JMS Bindings Extensions are not supported.
All services in your script should have the same security scenario.
This can be configured via the Protocols and Security tab.
Asynchronous Web Service calls and custom user handlers are not
supported for WCF.
The IsNonceIncluded and TimestampFormat properties of
web_service_set_security are only supported in Script view-not
in Tree view. LoadRunner cannot replay scripts containing the
soa_xml_validate function.
Note: For more detailed Web Services limitations, refer to the HP
Service Test readme.
Controller
Secure Channels

You cannot use the Host Security Manager utility to update security
settings on UNIX load generators that use rsh (remote shell) to
connect to the Controller.




You cannot use the Host Security Manager utility to change the
security mode of the load generator located over a firewall from off
to on.
When the load generator is located over a firewall, if the load
generator and Controller have different security modes,
communication cannot be established.
If the Controller machine is using secure channel communication,
the MI Listener should not be installed on the same machine as the
Controller.
If the Controller machine is using secure channel communication, it
will not be able to connect to an HP-UX load generator.
GUI Vusers


LoadRunner supports GUI Vuser scripts created using HP QuickTest.
GUI Vuser scripts created in WinRunner are no longer supported.
Windows Load Generator machines can only run one GUI Vuser at a
time. To run multiple GUI Vusers in a load test, you need to open a
terminal server session for each GUI Vuser. For more information,
see the HP LoadRunner Controller User Guide.
SiteScope


If you are configuring the SiteScope System Resources Graph
(System Resources Graphs > SiteScope), you cannot specify a
specific SiteScope user account. LoadRunner uses the default
SiteScope Administrator user.
For Sitescope 9.51 Users: If you want to configure SiteScope
monitoring with a SiteScope account other than the default
SiteScope Administrator account, you need to explicitly assign a
group with monitors to that account in SiteScope.
Analysis


Analysis currently supports Microsoft SQL Server versions 2005 and
up.
If you are using Microsoft SQL Server 2000, you need to either
migrate Analysis data or upgrade the server to 2005. The following
two tasks describe how to perform the migrating and upgrading
procedures:
To migrate old Analysis data to a SQL 2005 server:
1. From the SQL Server Management Studio, using Object Explorer,
connect to an instance of SQL Server Database Engine.
2. Expand Databases, right-click Analysis database, select
Tasks\Copy Database.
3. Follow the instructions in the wizard.
To upgrade SQL 2000 to SQL 2005:
1. Backup Analysis database on the SQL 2000
(http://msdn.microsoft.com/en-us/library/cc966495.aspx)
2. Uninstall SQL 2000.
3. Install SQL 2005.
4. Restore Analysis data from backup. (http://msdn.microsoft.com/enus/library/ms177429(SQL.90).aspx)






If you are using Microsoft SQL Server 2005 to store Analysis data
and you apply a global filter on the Analysis graphs, you may receive
errors due to a Microsoft limitation. If you receive an error, try and
apply the global filter again.
If you are using your own policy in an MS SQL server, you may need
to add your own account to the Analysis database template (in the
<LR Installation>\bin\dat folder).
When exporting Analysis reports to MS Word, take into account that
the content load may affect the table format within the document.
The following Analysis default settings have been modified: Include
Think Time is disabled and Generate complete data only is
enabled.
There is a limitation with MS Access and SQL queries when filtering a
large number of transactions (greater than 100).
Even after running the <Language> User Interface Pack, the
Analysis UI data generated from the sample session (in the <LR
Installation>\tutorial folder) will display in English. Filtering on
the graphs will fail. Workaround: Re-generate the graphs and then
the corresponding language from the <Language> User Interface
Pack will display and filtering will work.
LoadRunner Integration with HP Service Test


To use a Demo or Commuter type license in LoadRunner with
Service Test, run sntinit.exe from the product installation's bin
folder after the installation.
To use a Commuter type license in LoadRunner with Service Test, in
the WCommute utility, you must choose the entry Feature
"Service Test", version 9.0 —not a later version.
For more information about Service Test licenses, refer to the HP
Service Test Installation Guide.
WAN Emulation





There is no backward compatibility between the current
LoadRunner/WAN Emulation integration and any previous
integrations.
The integrated 3rd party software may not comply with accepted
Internationalization (I18N) conventions.
Selecting either Use bandwidth, or Use custom bandwidth in the
Network: Speed Simulation node in the Run Time Settings, may
interfere with the WAN Emulation settings and could lead to
unexpected behavior.
WAN Emulation is disabled if the host used as the Load Generator is
also used as the Controller.
WAN Emulation is not supported if the load generator is running on a
UNIX platform.
Windows Vista











To run LoadRunner on Windows Vista, User Account Control
(UAC) must be enabled for users with User privileges. For users
with Administrator privileges, UAC can be enabled or disabled.
Running the Windows Aero user interface on Vista machines, may
slow down VuGen UI performance.
On Vista machines, icons may not appear correctly in some dialog
boxes.
If LoadRunner is installed on a machine running Vista, LoadRunner
cannot be integrated with WinRunner.
On Vista machines, replay for LDAP scripts recorded over SSL is not
supported.
If you want to connect to HP Quality Center from a LoadRunner
machine running Vista and the Quality Center client is not installed
on your machine, you need to have Administrator privileges on the
Vista machine.
Replaying a VB Vuser on a load generator machine with Windows
Vista requires administrator privileges.
When running a LoadRunner Agent on a Load Generator machine
running Vista, it is recommended that you restart your machine after
installing LoadRunner, before running Vusers.
When running the LoadRunner Agent service on a Vista machine, the
Agent Configuration will not restart the agent service if it is already
running. To manually restart the Agent service, Choose Start >
Administrative Tools > Services. Select the LoadRunner Agent
service and choose Stop from the right-click menu. Restart it by
selecting the LoadRunner Agent service and choosing Start from the
right-click menu.
On Vista machines, when recording with MS Exchange (MAPI)
protocol, the read_next_mail and mapi_read_next_mail_ex
functions work only once per script, resulting in reading only the first
message in the mail box.
On Vista machines with UAC enabled, FTP sessions cannot be
recorded on Internet Explorer.
Workaround: Change the following Internet Explorer options:


Disable Protected Mode by clearing the Enable Protected Mode
check box under Tools > Internet Options > Security.
Check the Every time I visit the webpage option under Tools
> Internet Options > General > Browse history > Settings.
Multilingual Support



Language support. LoadRunner only supports English and the
native language of the machine's operating system. For example, if
you are using Japanese Windows XP, you can work with LoadRunner
in Japanese and in English.
Installation path. The path in which installation files for
LoadRunner are located, and the path in which LoadRunner is
installed, can contain only English characters.
.NET Framework 3.5 failure. Installing LoadRunner on a localized
machine may result in a failure in the .NET Framework 3.5
installation process, and you will be asked to terminate the
installation. This happens because the .NET 3.5 Framework
installation attempts to download the Framework Language Pack but
fails.
Workaround: Terminate the LoadRunner installation according to
the Installation wizard's instructions and invoke the LoadRunner
installation again.





Japanese characters in Web (HTTP/HTML) scripts. If you set
the advanced recording option to specify the encoding of an
application, and the application uses different character encoding for
different pages, then the recording log or script may display invalid
Japanese characters. This does not cause any errors in the script
replay.
Non-breaking spaces in Web protocols for Far Eastern
languages. A non-breaking space (      `\xA0',
etc.) cannot be represented in some Far Eastern locale character
sets (in which it is considered a lead byte). Instead, non-breaking
spaces are converted to regular spaces (` `, `\x20', etc.), both
during script code generation and replay. This may cause replay
problems, such as mismatches in length due to eliminating multiple
regular spaces. To work around this issue, either:
 Remove/add space(s) from/to the script so the comparison
succeeds.
 Specify regular expressions to avoid the issue.
Tutorial scripts. After the Language Pack installation, all sessions
and scripts in \HP\LoadRunner\tutorial are still in English.
Standalone installations. The installation interface of the VuGen
and Analysis standalone are in English and not localized.
Flex AMF call properties. Multibyte symbols in Flex AMF call
properties will be corrupted in the script text view.
