There is no need to initialize all 4K bytes with Nuls.
>length = fread(buffer, sizeof(char), 4096, fp);
Instead of hardcoding 4096, just use: sizeof(buffer)
(Provided it isn't a pointer.)

Re: Mobile Performance Testing
Well, if you are going to record a mobile device traffic with VuGen as a proxy, it means that first of all you need to start proxy recording in VuGen (for example IP: ABCD, port 8888). Then you want your mobile device to send all its traffic to the internet via this proxy. So second you will need to configure ABCD:8888 as the proxy on your mobile device (usually it can be done in network settings, here is iOS example). Once done, all device traffic will go thorugh VuGen and will be captured. Eventually after stopping the recording a script will be generated in VuGen. Of course, both the device and the VuGen machine need to be on the same network, but it shouldn't be an issue if you are connecting both to same WiFi network and disabling cellular traffic on the device.
All the above is explained in product documentation.

Re: Trying to select Radio Button in Truclient
Penn,
Thank you for your assistance. I am still getting Object not found. I have pasted the original data below and the JS created per your suggestion. I am not sure how to handle the GT signs and the data at the end. Please review and provide and suggestions or corrections. Again your assistance is greatly appreciated.
Original Input data
//input[@type="radio" and @value="551212>621212>FS>CMP>false"]
JS data
var PackageID=ArgsContext.TC.getParam("PackageID");
var LoanREQID=ArgsContext.TC.getParam("LoanREQID");
var str = '//input[@type=\"radio\" and @value=\"' + LoanREQID + '\">\"' + PackageID + '\">FS>CMP>false\"\"]';
evalXPath(str);

Re: How to read content from a file and storing it in a string variable?
>The initialization do not set the whole memory area with nulls, it will only set it to a null terminated char array.
That is NOT what the C99/C++ Standards say.
If static storage duration, it is all initialized. Function or block scope, every byte is initialized, if you initialize any.
(Assuming LoadRunner meets the C Standard.)
So you are better off just assigning the first byte: buffer[0] = '\0';
Unless dealing with security or you write the whole array and don't want random data.

Need help with Correlation in LoadRunner 12.53
Hi There,
I have a couple of questions regarding correlation in VuGen script and very much appreciated if I can get some help from you.
I have below parameter to correlate in VuUser script and need to parameterise the value in red.
web_url(
"URL=....%27VIS%27+icx_ticket=%27.6PrlVj5DFynvraqctdxJ_w..%27+resp=....",
"Referer=....icx_ticket&gv15=6PrlVj5DFynvraqctdxJ_w..&gp2=resp_app&gv2=",
)
nca_connect_server(".... icx_ticket='.6PrlVj5DFynvraqctdxJ_w..' ....");
My Questions are,
1. Since it does not have fixed LB and RB, I can't use web_reg_save_param or web_reg_save_param_ex
but I should use web_reg_save_param_regexp to cope with various paterns. Please tell me it I'm wrong
2. If YES from #1, then how to set RegExp= for the various paterns? I tried to use pipe but it did not help and ran into below error. ( IE, "RegExp=icx_ticket=%27.(.*?)%27+resp= | icx_ticket&gv15=(.*?)&gp2=resp_app&gv2= | icx_ticket='(.*?)'")
Error -35061: No match found for the requested parameter "CorrelationParameter_1". Either the specified boundaries were not found in the response or the matched text is longer than current max html parameter size of 81920000 bytes. The total length of the response is 4717035 bytes. You can use "web_set_max_html_param_len" to increase the max parameter size. [MsgId: MERR-35061]
3.If NO from #1, then how to parameterise the value in red?
Your comments or hint will be very much appreciated as I have already wasted a lot of time to resolve the issue.
Cheers,
Jason

Re: How to read content from a file and storing it in a string variable?
Interesting, there is always something new to learn. :-)
But the running point here is that all (automatic) variables needs to be initialized.
"In the absence of explicit initialization, external and static variables are
guaranteed to be initialized to zero; automatic and register variables have undefined
(i.e., garbage) initial values."
The C Programming Language 2nd Edition - Kerningham, Ritchie
This rule of thumbs is even more important to programmers not that experienced in C, like the thread creator.
Also if the time taken for clearing a 4k memory area is important, then I think we on a unsuitable Operating system ;-)

Re: Need help with Correlation in LoadRunner 12.53
Hi Jason
I think that your problem is trying to correlate in the wrong place. The correlation should capture the values when they are returned from the server the first time, and not in the call where they are used.
So you must find when and the data is returned by the server and then used it in the call like:
web_url(
"URL=....%27VIS%27+icx_ticket=%27.{correlation_param_1}%27+resp=....",
"Referer=....icx_ticket&gv15={correlation_param_1}&gp2=resp_app&gv2=",
)
nca_connect_server(".... icx_ticket='.{correlation_param_1}' ....");

Error during executing a scenario of C VUser script imported from SeeTest
I recorded a script using Experitest SeeTest Automation tool for mobile performance testing and then copied the code to C Vuser protocol in HP loadrunner.
It is not able to identify client
While executing the script in another machine, which have loadrunner(VUGen), is giving error:
ic_api.h(103): Error: An exception was raised while calling invocation function in interpreter extension cciext.dll: System Exceptions: Uknown.
Please help me in this issue as soon as possible.
And how to initialize a client in different machine in loadrunner C Vuser script?
I have provided the ip address in place of localhost in script.

Re: Need help with Correlation in LoadRunner 12.53
Hi OlaBerggren,
Which recording level should I select? HTTP based script? or URL based script?
I have recorded it in HTTP based script level ( by default) but couldn't find capturable data for correlation and below is only part where the value (6PrlVj5DFynvraqctdxJ_w) is searched.
web_url(
"URL=....%27VIS%27+icx_ticket=%27.6PrlVj5DFynvraqctdxJ_w..%27+resp=....",
"Referer=....icx_ticket&gv15=6PrlVj5DFynvraqctdxJ_w..&gp2=resp_app&gv2=",
)
nca_connect_server(".... icx_ticket='.6PrlVj5DFynvraqctdxJ_w..' ....");
I believe there must be a section where I can search "6PrlVj5DFynvraqctdxJ_w.." before web_url() so that script will capture the value from there and substitute {correlation_param_1} in web_url but unfortunately I can't find it in my current script.
Please advise
Cheers,

Re: Need help with Correlation in LoadRunner 12.53
Hi
Yes, there is other places to look. The values visible in the script is only what you send to the server and not what is coming back.
If snapshot was enabled, they can be found in the snapshot tab in the bottom. Or you can look in the output tab in the bottom and shift to the "code generation". Here all sent and recieved data is searchable.
Try reading some here about manual correlation and click around.

Re: Trying to select Radio Button in Truclient
Hi Idebner,
It seems you didn't combine your str correctly, try to copy&paste this one as your str:
var str = '//input[@type=\"radio\" and @value=\"' + LoanREQID + '>' + PackageID + '>FS>CMP>false\"]';
BTW, please make sure your two parameter table contains the correct value of the PackageID and LoanREQID.
if my solution works for you, please mark it as final solution :)

Are you running this on you own PC? If so, bring up task manager and see what your system resources are doing. I know when I do this on my own PC the max I can run is 20.

Re: Loading 50 Users failing in Controller and passed in Vugen replaying with 50 iterations(50 users
Hello Katpally
There are 3 major reasons why you cannot get more than 30 Vuser on a one time
1. The "Appliction under test" cannot hand the load of 30+ users
2. The load generator(s) do not have the Windows Resources (CPU. RAM, etc.) to handle 30+ vusers
3. There is a logic or data issue within your script(s)
It could be one or more of the above reasons. Are you monioring the Windows Resourses of your LGs and Citrix servers?
NOTE:
- IF you are use a multi-protocol script the Vusers will use 1 license PER protocol.. A script with both Citrix and web(http/html) protocol will use 2 license per Vusers (thus a max of 25 vuser using 50 license)
- The Controller (localhost) should not be use as a Load Generator.
Did you use the "Load generator calulator" to see what the max number of Vusers is for you LG and Script?

Help with TruClient Retries
i have some TruClient scripts developed with VuGen 12.02. i am running them in BAC/BPM 9.25.
i noticed in some of the BAC page component breakdown reports that there are several web page components, like .png objects, that are referenced with an __RETRY_#01 designation at the end of the URL. interestingly, i did not see any retry time listed in the Transaction Response Time Breakdown of the BPM performance over time report.
then, i ran the scripts from the BPM admin page, with extended logging enabled. i found examples of the __RETRY_#01 URL objects there, too. below is a portion of the report.
i would like to understand what these retries represent? how to control whether it retries, and how many times it retries? how to specify how long it waits for a page object? and whether these are settings typically in a browser or are something just in TruClient? (note that these objects are not something we have a TruClient WaitforObject on, and are not full BAC transactions).
