I have a heap dump file to analyze. ( produced by –XX:+HeapDumpOnOutOfMemoryError )
1. Is ther any way to get teh timestamp at which heap was dumped ?
2. I would also like to get the complete command line arguments for the JVM that dumped the heap
I tried both jhat & jvisualvm without much luck
3. What is the possibility that a heap file ( java_pidNNNN.hprof ) will be generated with –XX:+HeapDumpOnOutOfMemoryError, when there was no OutOfMemoryError ?
( I have 6 heap files generated for a JVM. However looking at the server log, I can only see one instance of OutOfMemoryError )
Does anybody know ?

I don't know a thing about HeadDumpOnOutOfMemory, but if it creates a file, every file I've ever seen has a date/timestamp of when it was created (or last modified). Can't you do a dir/ls and see when it was created?

Never ascribe to malice that which can be adequately explained by stupidity.
