RE: Profiling using OFBiz
Hi , Thanks a lot for your replies. I have used Your Kit JProfiler for checking memory leaks in the application. I find that Delegator, ModelReader and JobPoller objects hold the maximum place in the memory. But how should I detect memory leak and which OFBiz objects are causing memory leaks?? How should I solve the memory leak probe, if exists??? Kindly help me if there are any documents or steps to perform this.

Re: Profiling using OFBiz
Neha, I posted this message a few months ago about some profiling probes we wrote to measure method times. They work pretty well and allow you specify what you want to profile (e.g. com.mycode.* or org.ofbiz.entity, etc). I've been meaning to contribute these tools back with instructions on how to use them. I'll open a JIRA issue when I can get this complete. Brett /*/ We have been experimenting with the TPTP tools from eclipse to find performance bottlenecks. The tool let's you create your own custom probes that can be inserted at run time into your deployed application. The nice thing about these custom probes are they don't create a large footprint like so many other profiling tools. http://www.eclipse.org/tptp/ Here are some other links you may find helpful: Brett Articles on Eclipse Test and Performance Tools Platform http://www.eclipse.org/tptp/ http://www.vogella.de/articles/EclipseTPTP/article.html http://docs.hp.com/en/JAVAPERFTUNE/ Good article for WebSphere/ZOS with Sample probe code - http://www.redbooks.ibm.com/abstracts/sg247177.html?Open http://www.ddj.com/article/printableArticle.jhtml?articleID=184406433dept_url=/java/ http://docs.hp.com/en/JAVAPERFTUNE/bytecode.pdf On Fri, Mar 12, 2010 at 7:10 AM, Neha Mehta neha.me...@lntinfotech.comwrote: Hi, I need to check memory leaks, memory profiling and cpu profiling with OFBiz.

you can use probe application, which can be started from hot-deploy. cheers From: Neha Mehta [neha.me...@lntinfotech.com] Sent: Friday, March 12, 2010 6:40 PM To: user@ofbiz.apache.org Subject: Profiling using OFBiz Hi, I need to check memory leaks, memory profiling and cpu profiling with OFBiz.

Hi Neha, Our team had serious problems with memory leaks for 2 main reasons: 1) Lack of knowledge of the correct use of the Entity Manager. 2) In cases of a large number of request.
