- What
protocols does Load Runner support?
Industry standard protocols for example HTTP and ODBC are explicitly supported by Load Runner. Furthermore any protocol that communicates over a windows socket can be supported.
2. What do I need to know to do load testing in addition to knowing how to use the Load Runner tool?
In addition to knowing the tool :
- Management aspects of Load Testing, Planning being paramount
- Requirements gathering, Profile/Mix, SLA, Acceptance Criteria....
- an general understanding of the protocol you are working with, developers can be unhelpful
- a basic understanding of C programming
- know that you WILL be working with diminishing timescales and you are really at the END of the life cycle
- as a result of the above you may have to work unsociable hours including weekends
- Managers and other "Powes that be" - "Box tickers" will not understand your plight
- You need to be able to communicate effectively at all levels with different departments from Business to Dev to Sys Test
- voice your problems as soon as possible - Planning Planning
- Fail to Plan - Plan to FAIL
3. What can I monitor with Load Runner?
Monitor system bottlenecks during a test run and capture and display the performance data from every server or component.
4. How many users can I emulate with Load Runner on a PC?
Unlimited, No dead end.,
Depends on system response. That too intern depends on various factors like entire system configuration etc. If system bottle necks observes in very beginning or minimum no of V users no further addition of v users will be considered unless observed bottleneck is resolved.
5. What are the V user components in Load Runner?
Application Components used are client, database or additionally business application server.)
Web Server works on and through LAN,WAN,or WWW connection.
Application Server components are client, business server and database server without use of WWW.but through Protocols like FTP.
6. Load Runner Function - How to get current system time
This function is developed to use in Mercury Load Runner performance tool. This main use of this functions to return the current system time at any given point of time while Load Runner script is running.This functions can be used to report transaction times , script strati time and end time.
long get_secs_since_midnight(void)
{
char * curr_hr; /* pointer to a parameter with current clock hr */
char * curr_min; /* pointer to a parameter with current clock min*/
char * curr_sec; /* pointer to a parameter with current clock sec */
long current_time, /* current number of seconds since midnight */
hr_secs, /* current hour converted to secs */
min_secs, /* current minutes converted to secs */
secs_secs; /* current number of seconds */
curr_hr = lr_eval_string("{current_hr}>");
curr_min = lr_eval_string("{current_min}");
curr_sec = lr_eval_string("{current_sec}");
hr_secs = (atoi(curr_hr)) * 60 * 60;

secs_secs = atoi(curr_sec);
current_time = hr_secs + min_secs + secs_secs;
return(current_time);
}

Manual & Automatic Co-relation
Manual correlation - Correlation is used to obtain data which are unique for each run of the script and which are generated by nested queries.
Automatic correlation is where we set some rules for correlation. It can be application server specific. Here values are replaced by data, which are created by these rules.
