Muhammad,

I cannot tell you the reason for finding core_XXX directories in $ORACLE_HOME, outside of an application writing them there, so I won't even try to answer that part of your post. You can find the reason for the core dump files with a debugger like dbx, adb or gdb. The debugger will load the core file and report on the reason for the core dump. Most likely you'll find the reason as a segmentation fault which is, I believe, a memory error. A likely candidate for this is an application error when accessing the database instance. Run the core files through a debugging program and see what comes out. Also, check your alert.log for errors that could dump core, like ORA-0600 errors. This should tell you the time when the errors occurred and possibly why the core file was created.
