How to read a core file?

Heisemberg

A core has been generated. I know this file contains details of some crash or error occurred into the JVM. However, what tool are you used to load this core file?

core.4849890.06045307

Use jmap to convert the core file into a hprof file and then you can use any java profiling tool like for example VisualVM to analyse it.

Hi handat, thank you for letting me know about jmap.

However, the system is AIX and I couldn't find jmap out there. On other hands, there's dbx command, which loads well that core file.

I am not sure how far can I go with dbx, what can be read? please help

$ ls core*

core.11599898.04034722

$ dbx

Type 'help' for help.

enter object file name (default is `a.out', ^D to exit): core.11599898.04034722

Core file "core.11599898.04034722" program "webservd" does not match current program (ignored)
