The VS Profiler Team has an excellent post teaching how to use the VS2010 profiler with Silverlight Applications.

The steps are simple.

Run the A Visual Studio Command Prompt

And follow these steps:

  1. VSPerfClrEnv /sampleon
  2. "c:\Program Files (x86)\Internet Explorer\iexplore.exe" C:\Breakout\Breakout\Bin\Release\TestPage.html
  3. VSPerfCmd /start:sample /output:MyFile /attach:<PID of iexplore.exe process>
  4. Run your scenario
  5. VSPerfCmd /detach
  6. VSPerfCmd /shutdown
  7. VSPerfClrEnv /off

NOTE: information reposted from http://blogs.msdn.com/b/profiler/archive/2010/04/26/vs2010-silverlight-4-profiling.aspx

When the finish you will have a file called MyFile.vsp and just open that with VS2010.

ColdFusion 8 and JRockIt

JRockIt is an interesting Java Virtual Machine. I really admire the technology used in it. Well following Mike’s post about Memory Leaks in Coldfusion http://www.schierberl.com/cfblog/index.cfm/2006/10/12/ColdFusion_memoryLeak_profiler I was trying to configure the JRockit JVM to do some profiling on an important application.

But alas. Time just flies and things have change a lot since Mike wrote that post. So this is basically an update:

1) JRockit must be downloaded from: http://www.oracle.com/technology/software/products/jrockit/index.html You must accept the license and also have an OTN Account (this is a free process). Download the right version for your platform. I tried the x86 version on my 64 bit server and it didn;t work, so use the version that fits better to your platform. However there is no 64 bit client version of Memory Leak and all the other nice client tools. But dont worry. Download both version 64 and 32 bits versions. You will use the 64 version for your server and the 32 bit version for monitoring.

2) Stop coldfusion server

3) Modify the jvm.config file. In my case it was in: C:\ColdFusion8\runtime\bin\jvm.config

comment out old java.home and add a new line like:
java.home=C:/Program Files/Java/jrmc-3.1.0-1.6.0/jre

In the java.args setting, remove parameter –Xbatch (dont know why, it just didnt work)

add a parameter like:
-Xmanagement:ssl=false,authenticate=false,autodiscovery=true

*In my case I also had to disable security in C:\Program files\Java\jrmc-3.1.0-1.6.0\jre\management\management.properties with a line like:

com.sun.management.jmxremote.authenticate=false

4) Re start coldfusion
