Loadrunner Correlation of dynamic boundary

Loadrunner Correlation of dynamic boundary

LoadRunner Correlation is one of the most important concept in loadrunner, especially when you are working on web protocols in loadrunner like web(http/html), sap web or Oracle web applications. When dealing with complex scripts, we encounter scenarios where the usual web_reg_save_param function is not able to solve the purpose.

You can use following regular expression attributes  in your script to deal with correlation of dynamic boundary :-

  1. LB/DIG – This attribute interprets the # sign as a wildcard for single digit. eg:-  “Error5##” matches for “Error500”, “Error501” till “Error599”.
  2. LB/ALNUM – This attribute interprets the ^ sign as a wildcard for single US-ASCII alphanumeric character.
  3. LB/ALNUMIC – This attribute interprets the ^ sign as a wildcard for single US-ASCII alphanumeric character, this regular expression is case insensitive. eg:- “Er^^r” matches for “Error”, “ErRor”, “ErrOr”, “ErROr”, “Er12r”, Err1r” etc.
  4. LB/ALNUMLC – This attribute interprets the ^ sign as a wildcard for single US-ASCII alphanumeric character and lower case.  In this case “Er^^r” will not match for “ErROr”, “ErRor”, “ErR1r” and others with an uppercase alphabet present.
  5. LB/ALNUMUC – This attribute interprets the ^ sign as a wildcard for single US-ASCII alphanumeric character and upper case.
