Hi ..

I have a core_dump in the server... AIX 5.3 . It was created by on proc executable called "ProcessIse" . from the log report i found the source file name
"ProcessIseInterface.C" which created the core file.
the core file name is : "core" under /iprs/bin directory.

can you help me ? how do i start the investigation using dbx ?
what are all the commands should need to execute for fixing the bug?

Im very new to unix environment...so, can anyone give me your advice ?
