Jmeter Tips & Tricks
1) Please refere the below URL for the ADF controls recording in jmeter
http://one-size-doesnt-fit-all.blogspot.com/2010/04/configuring-apache-jmeter-specifically.html
2) Please find the jmeter adf correlation file below.
3) We need to use the below regular expression for the AFR Loop ID
_afrLoop”, “([-_0-9A-Za-z]{13,16})
4) Useful Video for the Jmeter ADF Application Recording :- http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/adfjmeter/adfjmeter.html
5) While running the large number of users , we need to adjust the below heap parameters
Ex:-
set HEAP=-Xms1024m -Xmx2048m
set NEW=-XX:NewSize=128m -XX:MaxNewSize=128m
set SURVIVOR=-XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=50%
set TENURING=-XX:MaxTenuringThreshold=2
set PERM=-XX:PermSize=64m -XX:MaxPermSize=128m -XX:+CMSClassUnloadingEnabled
rem set DEBUG=-verbose:gc -XX:+PrintTenuringDistribution
Note:- Don’t execute more than 400 per machine for 16GB RAM because it will cause the system crashe or heap dump of jmeter which impact the execution of the jmeter as well as response times of the execution.
6) If we have any socket time out error we need to modify the below options in jmeter.propertiers in all master and slave machines
http.connection.stalecheck$Boolean=True –> Hc.paramters
hc.parameters.file=hc.parameters –> Jmeter.properties
httpclient4.retrycount=1
httpclient3.retrycount=1

I don’t think that there is a limitation of 400 users per machine, I ran several thousands of virtual users on mid-end modern hardware. Check out 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article for more tweaks

Thanks for the info..
I tweak all the above mention options and currently working on Taurus & ur right , if we use taurus memory consumption is very low.
The above mention users, i am stating for the hardware like winserv-2008 with 16gb hardware and tweak heap memory to 2gb & its dedicated salve machine . We observed memory crashes
Please correct me if i am wrong
