What are the reasons why parameterization is necessary when load testing the Web server and the database server?
Anshoo_Arora
- Nov 7th, 2007
Generally, parameterization has two advantages:1. Makes scripts smaller/easier to understand2. Helps you use unique data in your scriptAlso, in LR you can use parameterization while working with data & time, when you have data dependancy and in the case of data caching.- Anshoo Arora

parameterization is done to check how your application performs the same operation with different data.In load runner it is necessary to make a single user to refer the page for several times similar in case of database server.

For testing the application, we need to have the basic scenarios done first,Second step will be to do the End to End testing with E2E scenarios,Third test will be to do the rigorous testing.Final step will be to do the load testing.

What are the disadvantages of using commercial performance / load testing tools?
gorbysbm
- Apr 14th, 2011
- you have to pay thousands of dollars to use it- there may be limitations on how many users you can launch without paying even more. There may be features that are disabled unless you pay more-You can't use the tool right away-- you have to wait till a license key is provided for you
kanthrajgowda
- May 23rd, 2008
You need to understand the need for any commercial tool with respect to the kind of technologies you use in your organisation. A tool that do not support the techniologies is waste of time and money. If it can fit into your requirements, there is a considerable ROI...Thanks, Kanthraj.9212264980.

what is defered graphs ? What are the different components in loadrunner?
gorbysbm

I did a google search and was not able to find any info on "deferred graph." AFAIK, the standard terminology for the graphs that give information about CPU, throughput, Error rates, etc, are called "correlation graphs", aka "reports graphs"

The script should fail when replayed may signifies a dynamic variable. In this case, watch out for "sessionid" or related type of variables. Also, a good way is to re-record the script to detect the differences. - papayamilkshake

What is performance baseline testing and at what stage of testing it is used?
semiletov
- Jul 20th, 2011
Baseline testing is testing to rule out possibility that large number of users causing system degradation, which is usually to expose problem that are not related to the actual load. That might be functional problem etc. Usually performed with as lowest number of users as possible, i.e. just 1 user.

Load Testing - What should be analyzed.
To determine the performance of the system following objectives to be calculated.1) Response time -: The time in which system responds to a transaction i.e., the time interval between submission of request and receiving response. 2) Think time -: Time taken to select new transaction after response for previous transaction is received. 3)Workload-: Work submitted to system by end user. 4)Throughput-:No...

LoadRunner fails on 302 redirect. Is this because of SSL?
Hi All,
I really hope someone here can help me. I’ve been to a number of forums and no one has been able too.
Problem:
A week ago I had my LR scripts all working. Now, after a new deploy they fail on a 302 redirect.
Basically the script sends one request for images and javascripts, which works fine. The second request submits form data to the... -

Can we do performance testing without using any tool?
anu1726
- Jan 11th, 2014
Manual performance test is possible but highly not recommended becoz for web applications we need to test the application under heavy load eg: e-commerce sites or bankings sites etc..And companies will go for automation tools for such projects
Nagarjuna
- Sep 5th, 2013
Performance testing can be done with out any tool. Like 1) If a product is developed for Windows OS with minimum 1GB RAM. We can test that application below 1 GB RAM. 2) By opening too many applications and test how the required application is performing.
