When replaying Web script with a correlation statement, the user receives the following error:
"No match found for the requested parameter 'ParameterName'. If the data you want to save exceeds xx bytes, use web_set_max_html_param_len to increase the parameter size."
Even though the user tries to increase the size for web_set_max_html_param_len, it does not help. What will be a good number for this parameter, and what is the maximum value?
Diagnosis:
When replaying a script with a correlated value, the replay engine will return the above error when there is no match found for the predefined boundaries on the correlation statement. The following information from the error message: If the data you want to save exceeds xx bytes, use web_set_max_html_param_len to increase the parameter size
The above is just a suggestion to try, it may not be a solution. This suggestion should be taken, only if the expected data is over xx bytes.
Solution:
Dealing with web_set_max_html_param_len
1. Find out the size of the data you are trying to retrieve. If it is over 256 bytes, increase this value. Correlation will fail if you try to retrieve a string whose length exceeds the maximum length specify by web_set_max_html_param_len.
Note:
The maximum length for web_set_max_html_param_len is maximum value of unsigned int, which is equal to 4294967295 bytes. If the data you want to save exceed this boundary, you will need to create multiple correlation statements for retrieving the entire dataset.However it is not recommended that such a big value be used and that a value closer to the maximum paramter length expected should be used.
2. If the data you want to save do not exceed the bytes specify in the function, you should focus on finding the correct boundaries or placing the correlation function on the correct place.
