Reply eam81969 says: October 23, 2013 at 2:50 pm On a multi-cored machine, is the CPU percentage calculated as an aggregate for all cores? There will normally be hundreds of threads in a javacore or threaddump for a moderately complex application. This investigation does not compare cpu utilization between hardware platforms but may be useful as part of those investigations. Solving proportions with 3 ratios, x:3:y = -2:3:-4 Should we eliminate local variables if we can? Solaris Prstat Load Averages

When running the command below: $ ps aux ...the if the STAT field begins with R, then the process is marked RUNNABLE by the kernel, which on most operating systems means I would strongly recommend this.Here we have differentiated the process stuffs in fiveCategories.1.Process status tools (Ex:prstat,ps)2.Process controlling tools (Ex:pkill,prun)3.Process inspection tools (Ex:pstack,pfiles)4.Process Lock Activity examination tools (Ex:plockstat)5.Process Tracing tools (Ex:Dtrace,apptrace,truss) 1.Process Note that registered members see fewer ads, and ContentLink is completely disabled once you log in.
