hi Naveen

yes LR can record the RTE protocol

please read the sections of the manual relating to the RTE protocol and then ask specific questions within the main forum

please note this is not a training forum, it is intended as a discussion forum for trained and experienced LR consultants

Posted on HP forums by Mark (Tomlinson)

"AJAX TruClient Virtual User is running at the UI-level and requires more memory and CPU resources per each virtual user.


Keep this simple equation in your mind: 1 hour of scripting = n dollars.

How many hours do you spend working on low-level script correlations? How many times do you have to completely throw away an existing low-level script and start over again (and repeat the scripting correlations)? How many hours are spent trying to explain a web_data_submit() function to a business analyst? Take all of those hours and multiply by n dollars. For example if your time is worth $100 per hour to the company, and you spend 80 hours working on a script...that's $8000 dollars.

If you switch to use Ajax TruClient - most of those low-level scripting complications are eliminated and you save all those hours of time. And, with Ajax TruClient you don't have to completely throw-out the old scripts with each new version of the application. That's even more time savings.

So, then you can spend that $8000 savings on more memory and CPU for load generators.

And with the time savings, generally - you can get to test execution faster, test analysis and results. You spend more time focusing on the application and performance issues...and LESS time messing around with scripts.


It's that simple."

@ ""Just Record and Replay" Sales talk"
What about retraining costs, getting everybody up to speed on Javascript now instead of C!

truClient looks a lot like Selenium, and looks like it scales just as badly as well as it runs headless browser instances.

Anyone know if truClient works with Flex?

Chid's right... Once you go TruClient... you won't want to go back. Don't take this to mean it is perfect... or easy. Those of us that have been around a decade or so in the LR world will have a learning curve... mainly because we are set in our ways. We are used to C.. now we have to learn JavaScript. We are used to seeing a script.... now things are more GUI oriented.

I think TruClient will only get better with time. I have already seen Patch 2 increase the capabilities of TruClient. The main problem right now is documentation and examples. I started another thread to try and help.. but I am hoping HP steps up to the plate with more examples.

Yes TruClient is hardware hungry. But hardware is 'cheap' nowadays as compared to a few years ago. CPU and Memory are key. Quad or Six Core processors should be your goal, with 4gb of Ram... probably less than a grand for that level of machine.

You will easily pay for the hardware with time savings in scripting. You are now looking at hours instead of weeks to script most scenarios.

If you hate correlation.. good... TruClient doesn't use it or need it. You hate the pseudo runtime browser that never displays the 'real' web page... good... TruClient doesn't use it.. it uses a 'REAL' browser to show you what's happening.

Like it or not... TruClient is the future. The vendors just can't keep up using the old protocols with the rapidly changing frameworks.

HI i have a doubt...?

I have three dependent links in which i have to distribute my 100 VUsers with different percentage

Example: All the 100 users will hit link 1 and now link 2 will be enabled, now only 60 users will click link 2,now link 3 will be enabled to all 60 users and only 25 users will click link 3.

All this i need to do in a single script by distributing my users in percentage.

Please help.....!!!!!!!!

Any idea...LR 9.5 supports Windows 7 with IE 8 or not ?

I am trying to record a web flow with vugen for the first time and IE is getting crashed... tried even with Firefox ...its the same.

I guess its compatibility issue vugen9.5 & win 7 with IE 8.0 ...


would IE 7 would work with vugen on win 7?can any one confirm it or share their views on this.

Note: I have admin rights on the recording PC

Re: tru client and the "hardware is cheap" mantra

That does not pass my smell test. Purchase price is not the only cost for hardware. Most corporations have a chargeback in place, so each desktop your company puts on the network results in a montly or yearly charge to the IT infrastructure bucket.

Factor in space, cooling, updates, etc, and all you are doing is shifting your costs. But that's ok! HP sells hardware right? Conflict of interest?

Nothing is impossible for the guy who supervises it!

As we have discussed in one of James' threads, HP sometimes is in the "cake and eat it" business. I don't think this is an attempt by HP to "sell more hardware". TruClient is a potentially useful, "C coder"-less method of creating sciripts. HP can now convincingly say "you don't need a professional C developer to create WORKING / VALID scripts."

      #671455 - 05/15/11 08:08 AM

Let me share with you my own thinking from when I was the HP LoadRunner Product Manager - as we were developing LoadRunner v11.0 with the AJAX TruClient vuser.

We all have recognized for years that the real objective of performance testing is *not* writing scripts (no matter what vuser type or language involved). The objective is to execute a test and analyze the results of the test - and to facilitate the resolution to performance bottlenecks. Therefore, our perspective was that script writing and script development is simply a prerequisite to conducting the test. It's a tax that every customer must pay.

Well, the objective for AJAX TruClient is to reduce that tax both in terms of time and also money. Why?

- because Agile/XP processes squeeze the time required to develop scripts
- because many more customers might afford the scripting tax if it *didn't* require painful correlations using old ANSI-C skills
- because paying the high-tax on a small load test (100-200 vusers) breaks the ROI calculation
- because paying the transport-level taxes still may result in an inadequate measurement of end-user-perceived response time

Also, we did not have any deterministic philosophy involved with releasing AJAX TruClient. Meaning, we did not intend to send a directive message to the masses about 'the one and only right way' or the 'wrong way' to choose your virtual user type. We thought about adding more choices and more options to your toolbox of virtual user technology. You have all the good 'ole virtual users that LR has always had (most of 'em)...and now you *ADD* new technologies like AJAX TruClient.

There's also no manipulative agenda in the HP LoadRunner R&D teams that I worked with. The team is dedicated to innovating and improving the product - so, please stop trying to read between the lines on some hidden message: 'thou shall abandon ANSI-C coding', or 'HP is trying to do X, Y or Z to trick us'...because that's not how they think.

Cheers,

-mt

In addition to above wht did each previous Patch add?

Critical Update :Additional critical functionality for TruClient Protocol

Patch 1 Critical Update : ALM side-by-side feature and Protocols Updates- Ajax
TruClient ,Web (HTTP/HTML) protocol - Data Format Extension
,Citrix updates, RDP updates, Flex updates.

Patch 2
The LoadRunner 11.00 Patch 02 release is a cumulative
release and contains the content from the Patch 01 release.

Ajax TruClient:

Object Identification:

1. Replay assistance- During replay, if TruClient cannot
locate an object in the script, it provides you with a
variety of options to locate the correct object in the
application, and enables your script to continue to
replay.

2. XPath- Object Identification now provides multiple XPath
suggestions.

3. TruClient includes two new functions in the JavaScript
area of a step:

1. evalXPath(XPath)- Returns an array of the objects
defined by the XPath in the argument.

2. random(array)- Returns a random item from the array
that is provided as its argument.

Steps:

1. Else condition- You can now add an Else condition to an
If section in a TruClient script.

2. Verify step- A new Verify step action was added for the
browser object. Possible properties to verify are Title
and Location.

3. Wait for Property step- A new Wait for Property step was
added. Wait for Property waits the amount of time
specified in the Step Timeout for the specified property
to match the specified value. The list of properties you
can verify depends on the role of the object.

4. Property verification- The list of properties you can
verify for each object depends on the roles of the
object and is no longer limited to visible text, all
text, and inner html.

5. New properties and functions- TruClient now includes
more functions and properties for use in your steps. For
details, see the sections on TruClient Functions and
TruClient Properties in the HP Virtual User Generator
User Guide.

6. Replace with parameter- You can now right-click a value
in a step and select Replace with parameter to
automatically replace a value with a parameter.

Snapshots:

1. Object icon- When you record a step on a button or
similar object in TruClient, the description in the step
may now include an image of the object.

2. Snapshots on errors- Snapshots on errors is now
supported for TruClient scripts in Controller.

3. Compare snapshots- You can now compare recording,
interactive replay, and load mode replay snapshots.

General:

1. Web page graphs- You can now view Web page component
breakdown graphs in Analysis for TruClient Vusers. Due
to the use of third-party components (for example,
Mozilla's Necko), Ajax TruClient measurements are less
detailed, and may be less accurate than in other
protocols. Some graphs (for example, Time to First
Buffer Breakdown) and some measurements (for example, SSL
Handshake, Client/Error Time) are not available.

2. Browser settings- Browser settings are now accessible in
the Ajax TruClient General Settings dialog box, in the
Browser Settings tab.

3. Bookmarks- You can now save bookmarks in the Ajax
TruClient General Settings dialog box.

4. Transactions- The Transaction Editor dialog box now
contains indications if your transaction is missing a
start or end step.

Citrix:

1. Functions- The functions Sync on text and Get text (text
trapping functions) for 32-bit applications are now
supported on Windows 2008 R2.

2. XenApp 6- Citrix XenApp 6 is now supported.

3. Update to Citrix correlation rule- This update should be
applied manually in order to preserve possible changes
made by the user. To apply the new rule:

1. Go to Tools > Recording Options >
HTTP Properties > Correlation node.

2. Click Import.

3. In the Import Correlation Settings from a File
dialog box, find the following: ..\LoadRunner >
dat > webrulesdefaultsettings >
CitrixSession_TokenRule.cor.

4. Click Open. The new correlation rule is added for
Citrix.

Flex:

1. AMF parsing- LoadRunner now includes improved AMF
externalizable object parsing (Action Messaging Format).
This makes the process of serializing using an external
Java serializer simpler and more robust.

2.RTMP

1. Messaging support- RTMP now supports enhanced record
and replay of messaging and has been verified for
Adobe LiveCycle Data Services ES2 Version 3.1.

2. Streaming support- RTMP now supports enhanced record
and replay of streaming.

When you record a Flex stream, by default, LoadRunner
now generates a single flex_rtmp_receive_stream step
in place of many flex_rtmp_receive and flex_rtmp_send
steps. The flex_rtmp_receive_stream step makes your
script more readable (eliminating tens or hundreds of
lines) and makes the replay more reliable.

Note: The new flex_rtmp_receive_stream step is
generated when the Generate flex_rtmp_receive_stream
step option is selected in the Flex:RTMP pane of the
Recording Options dialog box. Although this step
makes the script more reliable, it does not replay
certain actions you may perform while recording your
script, such as pause and seek. It also does not
replay the automatic requests that the client performs
when Dynamic Stream is in use.

If it is important to replay these actions, you can
clear the Generate flex_rtmp_receive_stream step
option in the Flex:RTMP pane of the Recording Options
dialog box, which causes LoadRunner to generate the
steps for all of the raw streaming data.

However, to ensure proper replay, you must manually
modify the generated script as described in Manually
Adjusting Recorded Flex RTMP Steps.

The above functionality has been verified for
Flash Media Server versions 3.5 and 4.0.

3. Externalizable objects- LoadRunner supports
externalizable objects over RTMP.

4. User Data Points- LoadRunner now generates a number of
new data points that provide more useful information
for analysis. Note that some of the less commonly
used Flex RTMP data points from previous versions were
removed.

Web:

1. Correlations rules- Correlations now use a new
web_reg_save_param_ex API which enables VuGen to find
more and more precise correlations.

2. Correlations Studio- The performance of correlation
studio was improved (scan for correlations).

3. Correlations- Step snapshots now include more information
about tasks that were initiated by the primary request.
Correlation rules now search this new more complete
snapshot.

4. web_reg_save_param_ex- web_reg_save_param_ex no longer
supports regular expressions for left and right
boundaries. To define the dynamic data with regular
expressions, use the new function,
web_reg_save_param_regexp.

General:

LoadRunner support on Visual Studio 2010- The LoadRunner
Visual Studio add-in now supports Visual Studio 2010.
