I am attempting to use Eclipse MAT (Memory Analysis Toolkit) to analyze some rather large heap dumps (~2G). My laptop unfortunately 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?
A:
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.

Thanks. I need to try this out before awarding you the bounty, but it looks promising!

These options are not really necessary

@kohlerm : not necessary, but will insure that the reports are pre-built, and not run on the lower-memory machine.

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.
