Features and benefits of IBM Rational Performance Tester

Features and benefits

Features	Benefits
Scriptless Testing	No programming knowledge is necessary to create, comprehend, edit or execute a performance test. Tests are displayed as hierarchical list of the Web pages that will be visited during execution. While test complexity is masked by default, advanced testers have access to all transactional information such as underlying page elements and server responses.
Find and diagnose the cause of performance problems	Rational Performance Tester goes beyond problem identification to problem diagnosis. Using Root Cause Analysis features, you can identify both the source code and physical application tier that is causing the bottleneck. With the generated UML sequence diagrams you can trace all activity that occurred just prior to the bottleneck to truly enable you to address the root cause of your performance problem.

Rational Day for Testing!

Hello All,

I have attended Rational Quality Management Center and Rational Performance Tester training which was held in Applabs, GEC by IBM folks. I find some things to be interesting in both of the tools. As part of Performance, I find RPT tool to be a good one but certainly has some limitations, in this tool there are definitely some good things covered as part of analysis, say for eg. Response Time Break-up on all the Layers which is a very good feature because I see none of the Performance Testing tool in the industry does this. Drawbacks are; it doesn’t support IIS, they were saying that they will support it in their next release and also another toughest thing which I found is managing the Script Framework, probably the guy who have given the demo doesn’t have much knowledge on the tool, which I feel should be explored.

And one good news to all, probably for the guys who are most interested in attending IBM Rational Software Conference 2009 (RSDC) which is going to be held on 11th of Aug in Taj Banjara. Hyderabad.

You need to pay a registration fee of 1000/- and for getting certified on any rational tool(need more clarity on which tool’s they are talking about) they are charging a very nominal amount i.e. 500/- and eligible to take the exam for 2 times.

Why tune SQL?

Hello,

Here is a good article on "Why Tune SQL and the Best Practices that needs to be adapted for tuning an SQL" I liked the way the Author presented the information which is really cool and in a more understandable format and hope you all will like it.

Thanks a lot to the Author!

rstat daemon on Unix

Hello All,
Most of you might know that few times we see that LoadRunner doesn't collect OS metrics on Unix, this might be due to 2 reasons, rstatd was not configured or that daemon was not running on that machine. This is important standard performance meter to work.We can achieve this by doing the following.

rstatd prerequisites
Ensure that the rstatd daemon is running on the monitored computer by verifying the presence of the following entry in /etc/inet/inetd.conf
rstatd/2-4 tli rpc/datagram_v wait root /usr/lib/netsvc/rstat/rpc.rstatd rpc.rstatd

By default Solaris 5.10 disables it .
# svcadm enable rstat
to verfiy whether it is running, run rpcinfo -p

Location of rpc.rstatd can vary among different Operating systems.
