How Do you Parameterize a Citirix Script?

[Stimely, Noelle]

Below is text captured from a Citrix recording. I do not see my patient name (parameter) listed like I do in normal scripts. I am using Citrix + HTTP Protocol to record.

vuser_init()
{

ctrx_set_connect_opt(APPLICATION, "#Hyperspace 2010-SUP");

ctrx_set_connect_opt(NETWORK_PROTOCOL, "TCP/IP + HTTP");

ctrx_connect_server("64.54.43.254:1494", "loadrunner1", lr_decrypt("4d65322c54bf1230aeed14fc637d1a"), "ucsfmc", CTRX_LAST);

ctrx_wait_for_event("LOGON", CTRX_LAST);

lr_think_time(7);

ctrx_sync_on_window("Hyperspace - UCSF SUP", ACTIVATE, 64, 39, 1025, 768, "", CTRX_LAST);

ctrx_type("ipuc", "", CTRX_LAST);

ctrx_key("TAB_KEY", 0, "", CTRX_LAST);

ctrx_type("model", "", CTRX_LAST);

ctrx_key("ENTER_KEY", 0, "", CTRX_LAST);

ctrx_key("ENTER_KEY", 0, "", CTRX_LAST);

lr_think_time(9);

ctrx_sync_on_window("Hyperspace - 14L MEDICINE - UCSF SUP - CLERK I.", ACTIVATE, 98, 9, 1025, 768, "", CTRX_LAST);

ctrx_mouse_click(242, 35, LEFT_BUTTON, 0, "Hyperspace - 14L MEDICINE - UCSF SUP - CLERK I.", CTRX_LAST);

lr_think_time(4);

ctrx_mouse_click(271, 329, LEFT_BUTTON, 0, "Hyperspace - 14L MEDICINE - UCSF SUP - CLERK I.", CTRX_LAST);

ctrx_mouse_click(945, 230, LEFT_BUTTON, 0, "Hyperspace - 14L MEDICINE - UCSF SUP - CLERK I.", CTRX_LAST);

ctrx_type("t", "", CTRX_LAST);

ctrx_key("TAB_KEY", 0, "", CTRX_LAST);

ctrx_type("n", "", CTRX_LAST);

ctrx_key("TAB_KEY", 0, "", CTRX_LAST);

ctrx_key("TAB_KEY", 0, "", CTRX_LAST);

ctrx_key("TAB_KEY", 0, "", CTRX_LAST);

ctrx_type("3", "", CTRX_LAST);

ctrx_key("TAB_KEY", 0, "", CTRX_LAST);

lr_think_time(10);

ctrx_mouse_click(987, 716, LEFT_BUTTON, 0, "Hyperspace - 14L MEDICINE - UCSF SUP - CLERK I.", CTRX_LAST);

ctrx_mouse_click(997, 111, LEFT_BUTTON, 0, "Hyperspace - 14L MEDICINE - UCSF SUP - CLERK I.", CTRX_LAST);

ctrx_mouse_click(976, 31, LEFT_BUTTON, 0, "Hyperspace - 14L MEDICINE - UCSF SUP - CLERK I.", CTRX_LAST);

ctrx_mouse_click(1014, 10, LEFT_BUTTON, 0, "Hyperspace - UCSF SUP", CTRX_LAST);

ctrx_disconnect_server("64.54.43.254:1494", CTRX_LAST);

return 0;
}

Noelle,

I suggest you follow the LoadRunner Citrix scripting best practice:

1. Use keyboard. Ideally over 95% of your script's input data should be fed via key strokes rather than mouse clicks. Mouse click often tends to fail during replay and can hide parameter inputs. Your input won't get captured if your patient was selected from mouse click.

2. Install Citrix agent on the server box to increase the robustness of your script. Citrix agent allows Loadrunner to recognize application objects such as buttons and fields by their properties. This increases the accuracy of object activation during script replay.

3. Decrease the type rate when in runtime settings.

4. Always have a batch program to kill the previous terminal session before starting the next iteration. You can use the system() function to do this bit. Typically when you re-iterate a flow - certain windows/popups might not close and can disrupt the flow of screen sequence. This can be avoided by disconnecting the session and reconnecting it back before starting a new iteration. One MAJOR trade off with this approach is that you will logging unusually high number of times than real world logging attempts. Get a consent from your client before you do this.

There are more points, but

Yes it is compatible with Windows server 2008. In the LoadRunner disc you will find loadrunner citrix agent in the additional components section. It is an installable file (exe).

I am using Citrix Xen App 6.0 hosted on Windows server 2008.

Lr 11.0 on Windows server 2003.

 

I want to install LR citrix agent on Citrix Server,

 

Let me know is it compatible , if it is compatible please help me in installing it.

 

Thanks in advance

Only agent installation is sufficient. Remember to inform the client about the additional memory and CPU usage consumed by this agent on the server. ~2mb of physical memory space is consumed per vuser by ctrxagent.exe process during test execution. You can see this agent process spawned during load test from via task manager in the Win 2008 server. So if you are running a 20vu test then 20*2 mb of space will used in the server only for ctrxagent.exe process. You will have to carefully deal with this issue. Inform you client about the pros and cons of using this agent on this server. It will affect your test results significantly however this is the only way you can create a relatively robust citrix loadrunner script. The problem is choosing between testing approach against accuracy of test result.

Chaitanya,

 

is it required to install LR 11.0 on windows server 2008 and then install the Citrix agent which is in Additional components  (or)  only installing Citrix agent which is in additional components is enough.

Chaitanya, can you tell me more about this? Do you have a sample batch
script that you could share? :-)

Thanks in advance!

Also, there are 2 Loadrunner Citrix agents.  Be sure to install the 64 bit agent which was added to support in January.

I logged a ticket with support to find out how to parameterize a Citrix script this was their response:

 

For the Citrix section, you can create parameters normally and replace certain values in the script.

For example :

Ctrx_type("shellfish", "", CTRX_LAST);

You could create a parameter for the value of shellfish, resulting in :

Ctrx_type("{DATA_PARAM_1}", "", CTRX_LAST);

 

Values in the ctrx_type function ( from your script : ‘fammd’, ‘model’, ‘test’, ‘98.5’, ‘shellfish’, ‘shee’, ‘llfish’; which are your input data ) can be parameterized.

Correlation doesn’t exist in Citrix, since there is a synchronization via bitmaps.

 

Hope it helps!

 

Noelle
