JMeter Learning

My Learning with JMeter.
This new year, i will come with some post on my learning with JMeter. This is the first inital post, which is starting point.


Apache JMeter

Apache JMeter is Open Source Software, a 100% pure Java desktop application designed to load test client/server software (such as a web application ).
 It may be used to test performance both on static and dynamic resources such as static files, Java Servlets, Perl scripts, CGI scripts, Java objects, databases and queries , FTP servers , and more.

JMeter can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types.

JMeter can help you regression test your application by letting you create test scripts with assertions to validate that your application is returning the results you expect. For maximum flexibility, JMeter lets you create these assertions using regular expressions.

Starting to Use:

To Install JMeter we need to just download the binaries .zip from the given link: http://jmeter.apache.org/download_jmeter.cgi

Download Jmeter, and install by unzipping the .zip file in any directory. Go to apache-jmeter-2.8\bin folder, it has the files shown is screenshot below:


 To Start JMeter, Double Click on Jmeter.bat. JMeter will start with the below initial screen.
The user interface has two panes. The left pane displays the elements used in our testing. Initially, there are the Root and two sub-elements, Test Plan and WorkBench.

Test Plan: A test plan describes a series of steps JMeter will execute when run. A complete test plan will consist of one or more Thread Groups, logic controllers, sample generating controllers, listeners, timers, assertions, and configuration elements.

WorkBench: Workbench is place where we store test elements which are saved and used in later stages. We can add two non test-elements which are HTTP proxy server and HTTP mirror server. Http proxy server is used for recording purpose.
To use it right click on workbench  then select Add --> Non-Test Elements --> HTTP Proxy Server.

Lets see some terms related to JMeter in next post.

Steps to Analyze AWR Report in Oracle

Steps to Analyze AWR Report in Oracle AWR -   Automatic   workload repository is a collection of persistent   system performance   statistics   owned by SYS. It resides in SYSAUX   tablespace . By default snapshot are generated once every 60 min and maintained for 7 days . Each snapshot has a unique ID know as "snap_id". Snapshot detail can be found in " dba_hist_snapshot " view.   If we have Database performance issue and not the Database machine, then AWR Report is the place to look at. AWR is not used for real-time performance monitoring like the v$ tables. It is used for historical analysis of performance. AWR complements, but doesnot replace real-time monitoring. Once AWR Report is generated in Oracle, the next task is to analyze it. By going through the AWR Report we can easily solve issues like slow database, high wait events, slow query and many more issues. Even though the report is lengthy, Analyzing or Reading re...

Vmstat Output explained

-
vmstat : vmstat is a tool in Unix/Linux which is used to Report virtual memory statistics. It shows how much virtual memory there is, how much is free and paging activity. Most important, you can observe page-ins and page-outs as they happen.   vmstat   reports   information about processes, memory, paging, block IO, traps, and cpu activity.   > vmstat procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu-----   r   b    swpd    free    buff   cache         si    so     bi     bo    in    cs us sy id wa st   0   0   21688 12797396 850716 15372668     0     0      3     35     0     0   1   0 99   0   0   0   0   21688 12789292 850716 15372668 ...

Verifications and Error Handling in LoadRunner *Web_reg_find and Web_reg_save_param*

-
Verification's and Error Handling Verification points must be inserted into the scripts to verify the application being tested with the load. Verification function that are used in our application are:  Web_reg_find, web_reg_save_param These verification should be outside towards the end of the transaction. Mandatory verification points: ■          Login – whenever there is a login, verification points must be added to verify that the user logged in correctly. ■          Update Transactions – transactions that update the database must be verified that they are successful. ■          Each page should be verified using Web_reg_find function Using Web _ reg_find for verifications. Example: web_reg_find("Text= Main Package","SaveCount=Verify_Count1",LAST); Verification: if (strcmp(lr_eval_string("{Verify_Count1}"),"0")==0) { ...
