Loadrunner - Workbrain/Cognos Capturing Issue

Jump to solution

Hello,

 

I'm having some problems with capturing Cognos report [PDF] information  (nested in an <iframe> tag).

 

When I access the Cognos reports through a browser through the Workbrain appliaction the reports always display without any issues so functionally it is working properly.  I have yet been able to produce any kind of error accessing these reports in question via a browser (manually).  I was also able to record and replay these report workflows without any issues prior to the introduction of the Cognos load balancer.  As soon as the loadbalancer was introduced there seems to be random correlation failures upon replay.  The failures are always with the same iframe cognos capture and can happen upon any iteration[random].  The loadbalancer is set to keep session persistence and sits in front of our two web servers, which also sits in front of the two application server.

 

I've tried running with and without Wininet setting in LR, bumped my web_set_max_param_len to more than enough bytes and I've even got some people on the development team to turn off server a cognos web server (as to force only one) and also the same with an cognos application server, all to no avail.  I'm at a complete lost as to why my scripts randomly fail when trying to capture the cognos information in the <iframe> after the introduction of loadbalancing.

 

Please help.

Thanks in advance.

Thanks for your help.

 

I did manage to figure it out.  Took lots of tweaking as my scenario is setup differently from the IBM documents however I did get it working properly.
