Re: LR recording protocol for Cognos Contributor 8.4
1. Make sure you are honoring all of the environment requirements for your version of LoadRunner. Requirements for the latest version of LoadRunner are noted here
2. Make sure you have the appropriate rights in your operating system, as defined by the installation guide
3. Make sure you are operating in a 'clean' environment where other applications or processes will not be interfering with your ability to record.
4. Examine architectural diagrams for your application environment for clues as to the nature of the conversation between the client and the next upstream component
5. Grab a protocol analyzer and see what application layer protocol is identified by the analyzer
"Which protocol do I pick?" is the #2 question for all LoadRunner usage across multiple forums. "What is correlation?" or related "How do I correlate?" together make up the #1 question topic.
