These are my notes
1. what are Jprofiler & Jconsole
Jprofiler/jconsole are GUI based debugging tool for java files.These provides the 5 level view.Handy to debug a java program by visualizing its behaviour at memory level (memory views ) ,Head walker,CPU view, there level view to identify dead lock related issues & VM telemetry views.
2. How it is different from Dtrace.
Dtrace have lots more utility than this.Dtrace provides the OS level view, i mean how many times the script or program visit to kernel and uses the s/w or h/w interupt. Dtrace can be used for other languages or scripting ( like jpython,jruby,java). the idea is based on probs and hence it is more memory intensive useless use of prob may increase time overhead charges.
Jprofiler is good in its GUI quality,light weighted.
3. How one can atain local vitualization in solaris.
There are many ways , using VMWare or Xen . VMWare is build over ESX which is lying over Virtual machine,whereas Xen doesnot need ESX and hence uses less amount of memory.
4. What are the important utilities of Dtrace ?
Dtrace us used to look inside, identify the problem ,root cause and can handle a large volume of project.
5. What are different components of Dtrace ?
