Hi ,
I was able to install memory analyzer tool via eclipse update site..
But now i couldn't switch to "memory analyzer perspective" (i dont see such kind of perspective) or i don't get *.hprof file when i run a java program...(i did a VM setting -XX:+HeapDumpOnOutOfMemoryError)

Any help please?

Rgds,
Ratha.

Hi,

>> But now i couldn't switch to "memory analyzer perspective"

Did you list all available perspectives, because Memory Analyzer is not showing up in the pre-populated list?
Go "Window" -> "Open Perspective" -> "Other..." and look for "Memory Analysis"
If it is missing among "Other..." can you look for some message in the error log which could be related?

>> i don't get *.hprof file when i run a java program...(i did a VM setting -XX:+HeapDumpOnOutOfMemoryError)

With this option you will get a heap dump only if the VM runs into an OutOfMemoryError. Is this the case?

I haven't experienced the problem so far. Are there any messages the error log?

>> i couldn't see such *.hprof file...
The file (if written) should be in the working directory of the process. The VM also writes some statements to the console when writing the heap dump. Are there any?

Hi,
I think the problem with my installation..anyway i haven't faced any issue with code development..only issue with the plugin install..(i checked with 'findbug' plugin also.. it didn't work)
Now again got a fresh distribution and tried to install both plugins...they work fine..

Thanks for answering me...

Regards,
-Ratha.
