eclipse MAT in headless mode

[Luca Maderna]

Thanks Bernd,

Unfortunately I can't work on production remote machine.
So I launched on my pc

ParseHeapDump.bat <dumpFile> org.eclipse.mat.api:suspects
org.eclipse.mat.api:top_components #

after few minutes goes in OutOfMemory, so now I'm retrying setting in
MemoryAnalyzer.ini a larger memory setting.

Anyway, when ParserHeapDump finish correctly how can I use these index
files?
I've only to open my *.hprof file and MAT automatically use index and
report files?

thank you very much
luca
