Genrating a stack from core dumps in unix and linux

Follow the instructions below in order:

1.      Check if you have a core file, we may find in cdump or bdump/trace or bdump or cluster log locations.

2.      Log into the user (the user need to be the owner of the core file) Then issue

               file <CORE_FILENAME>

The above output gives more info like from which executable (program) the core generated and other.

3.      Log into the user (owner of the program). Go to ORACLE_HOME/bin or GRID_HOME/bin, then issue

                file <Program>

Note: if possible give read permission to the program  (optional)

                chmod a+r <program>
