HTTP status code 500 INTERNAL SERVER ERROR messag

[raj12345]

iam seeing the following error when running the vugen script in
performance center

no match found for the requested parameter "USERPARAMTER" . check
whether the requested boundaries esxist in the response data. also if
the field you want to save exceeds
256 bytes, use web set max html param len to increase parameter
size,.. how to fix this error???

iam seeing one more error HTTP status code 500 ( internal server
error).. how to fix this two errors?

[James Pulley]

Your first item, 'no match found for the requested parameter
"USERPARAMTER,"' is directly related to a failed correlation. This can
happen either because your LB|RB|ORD conditions cannot be satisfied due to
changing conditions on the page, or the page you are expecting not being
returned. Make sure to follow testing practices for checking for expected
results, or in this case checking for the correct expected returned page,
with each request and branch your script execution as appropriate.

As to your 500, there are many causes for these, but ultimately it is
because you have handed the server a set of data which is out of context for
the data it was expecting and it throws it proverbial hands up and screams
back, "I don't know what the heck you want me to do with this data," or as
we see it, an HTTP class 500 message. A more than fair portion of these
that occur in testing are false 500s, particularly if you are not checking
for proper returned pages and then branching your code appropriately based
upon what shows up on the page. Example, if a valid 200 class page is
returned, but the page is not one which is expected within the business
process flow and you continue your business process including the submission
of form data which is out of context for the pages returned you will most
likely receive a "false 500" caused by your test design back from the
server. This is termed a "false 500" because an end user would have never
been able to make the same request because the end user interface would have
disallowed the out of context request as submitted by the test tool which
was ignoring the context of the pages returned. The larger the number of
variables related to state, session and business process data which require
correlation on a submission the higher the likelihood that you are going to
see these errors if you don't follow established testing practices for
checking for expected results for each step. As you might expect these can
be extraordinarily common in Microsoft asp/x environments which make use of
large state management variables.

1. check the application manually when you get 500 error if it is working

then use web_set_max_param_length("100000");

in the begining of init, action and vuser end.

Because you can do things in a virtual user to ignore the context of the returned pages which you cannot do when engaging in the same process on a manual basis.  Granted, this willingness to ignore the expected results of a test step represent poor test process -- but then a chisel in the hammer of one person results in the in a work of art which inspires, in the hands of another person simply results in lots of stone chips.
