String Comparison in Loadrunner script


How to compare a string in Loadrunner script?

-There are various methods to compare a string, in below example we have used "strcmp" to compare two values. We have captured a string in "pComparisonString" parameter and comparing it with ABC. Lets say if you have captured some string using correlation and want to compare if the captured string meets the condition then only pass the transactions else fail the transaction:

if (strcmp(lr_eval_string("{pComparisonString}"),"ABC") == 0)
{
lr_output_message("The parameter value is %s", lr_eval_string("{pComparisonString}"));

lr_end_transaction("Transaction_Failed",LR_FAIL);
}
else
{
lr_error_message("No parameter value captured.");
lr_end_transaction("Transaction_Passed",LR_PASS);
}

--------------------------------------------------------
strcmp- String comparison function.

pComparisonString- String which we have captured for comparison.

ABC- string with which we want to compare, you can replace it with the actual value.

Pacing Time in LoadRunner

What is Pacing? Where and why to use it? -Pacing is the time which will hold/pause the script before it goes to next iteration. i.e Once the   Action   iteration is completed the script will wait for the specific time(pacing time) before it starts the next one. It works between two actions. eg, if we record a script there will be three default actions generated by the Load Runner:   vuser_init, Action   and   vuser_end,   the pacing will work after the   Action   block and hold the script before it goes to repeat it. The default blocks generated by LoadRunner is shown below: Actions marked in Red Now we know what is pacing and we use it between two iteration. The next question comes to mind is why we use pacing: Pacing is used to: To control the number of TPS generated by an user. To control number of hits on a application under test.     Types of Pacing: There are three options to control the pacing in a script: General Pacing:    1. As soon

Error handling using Text Check

Error handling using if else condition. web_reg_find("Search=All",                      "Text/IC=Home Page",                      "SaveCount=home_count",                       LAST); //then after login block paste this code: if (atoi(lr_eval_string("{home_count}")) > 0)                 {                       lr_output_message("Log on Successful");                 }     else               {                     lr_output_message("Log on failed for the Login ID: %s", lr_eval_string("{pUserName}"));                     lr_exit( LR_EXIT_ACTION_AND_CONTINUE,LR_FAIL );                }

How to troubleshoot high Memory utilization during performance testing

 When troubleshooting high memory utilization during performance testing, it's important to identify the underlying causes and take appropriate steps to address the issue.  Here are some steps to troubleshoot high memory utilization: Monitor Memory Usage: Use performance monitoring tools to track memory usage over time. Monitor both physical and virtual memory (RAM) to identify if memory consumption is exceeding available resources. Identify Memory-Intensive Processes: Identify the specific processes or components that are consuming a significant amount of memory. Performance monitoring tools can help you identify the memory-hungry processes. Look for any particular application, service, or module that stands out in terms of memory usage. Analyze Code and Memory Allocation: Review your application's code and algorithms to identify any memory leaks, inefficient memory allocation, or excessive object creation. Look for areas where large amounts of memory are being consumed unnece
