Re: running jrockit with CFusionMX7 to find memory leak
1 think this is the easiest way to use memleak. 1) Copy the license file to your JRE-directory. See: http://dev2dev.bea.com/jrockit/tools.html 2) Start JRockit with -Xmanagement:port=7091,ssl=false,authenticate=false 3) Start Mission Control and click new connection in the JRockit Browser toolbar. Set the host(localhost) and port(7091). 4) Right click on the connection you've just created and select Memleak. ~| Create robust enterprise, web RIAs.

running jrockit with CFusionMX7 to find memory leak
I have been having a terrible time trying to get jrockit running with coldfusion. I have coldfusion MX 7 running and installed jrockit (jrockit-R27.3.1-jdk1.5.0_11). The reason I am trying to run jrockit is to use their memory leak tools to find a memory leak on my server. It crashes nearly daily because it runs out of memory. I have tried following the information on this page but it has not worked: http://www.schierberl.com/cfblog/index.cfm/2006/10/12/ColdFusion_memoryLeak_profiler So far I have made these changes to the jvm.config file:l java.home=C:/Program Files/Java/jrockit-R27.3.1-jdk1.5.0_11/jre Also, I added the following at the end of the java.args: -Xmanagement According to the post, I should add this to the java.args but doing so prevents cold fusion server from starting: -Xmanagement -Djrockit.managementserver.port=9010 Okay, so by just using the '-Xmanagement' cold fusion starts and I am able to run jrockit. Once in jrockit, under the 'connectors' it shows localhost:80 however I am unable to start the memory leak or do anything else with that (timeout failures). Under 'discovered' within 'local' it shows com.jrockit.mc.rcp.start.MCMain. I am able to start memory leak on that connection, but I believe it isn't the correct connection. It seems as if there is some disconnect between my localhost and the jrockit. Any advise or directions would be greatly appreciated. ~| Create robust enterprise, web RIAs.

Re: running jrockit with CFusionMX7 to find memory leak
This is not relating to jrockit, but do you happen to be running FusionReactor? There was a bug in v2 of FR that, in some instances, caused the ODBC Wrapper to make memory climb. This has been fixed in their 2.04 release - and works great I might add. Just thought I would though that out there in case you are running FR with the ODBC wrapper.

RE: running jrockit with CFusionMX7 to find memory leak
No reason to completely switch out the JVM for this..

Re: running jrockit with CFusionMX7 to find memory leak
varScoper looks good, but this page uses cfscript which doesn't work w/ varScooper. I am currently downloading Java SE 5.0 so I can try out jvmstat. After I download a new version of Java, I assume I need to point coldfusion (through the admin interface) to point to the new instance of java. At that point I should be able to use jvmstat.

RE: running jrockit with CFusionMX7 to find memory leak
Have I missed something here? Things like visualgc, FusionReactor etc just tell you how big the heap is. Unless you can pin down the memory leakage to particular moments in time, this doesn't help much. We need to know what's in that heap. From what I've seen the only one of Sun's tools that runs on the 1.4.x JVM is visualgc. The heap analysis tools require later JVMs, which CFMX7 does not support. That leaves us with things like OptimizeIt and JProfiler. I'd love to know if there's another way. I have a memory leak on my production server which I've been unable to reproduce on dev, and don't want to load down production with instrumentation. My current plan is to upgrade to CF8 and a) see if the leak goes away and b) get into the JVM 1.6 good stuff like JHAT.
