How to use existing Eclipse MAT indexes for interactive analysis

I am attempting to use Eclipse MAT (Memory Analysis Toolkit) to analyze some rather large heap dumps (~2G). My laptop u开发者_C百科nfortunately has 32bit Windows, and MAT runs out of heap space @ 1.4G allocated heap. I was successful in running the heap indexer from the command line on a large, headless 64bit box. However, I am unable to convince MAT to import these index files from a directory on my laptop so that I may investigate the heap interactively. All my attempts at loading the heap (with the index files alongside it) have resulted in MAT deciding to re-parse the heap file instead of using the existing indexes. Ideas?

You need to copy all files which are present in that directory to your laptop. I've done this successfully many times. I run the analyser on the server using

/opt/mat/MemoryAnalyzer -consolelog -application org.eclipse.mat.api.parse "$@" org.eclipse.mat.api:suspects org.eclipse.mat.api:top_components

This allows me to open the heap dump and then open the stored reports.

You just need to copy all the files that have the same file name prefix to the new location. It's really as simple as that.
