Please advice me , how to resolve the problem ...

Some more information about ProcessIse core_dump from dbx :
***********************************************
(/usr/bin/dbx) where
ustart() at 0x9fffffff0000240
(/usr/bin/dbx) step
stopped in IprsIseInterface::execute(int,char**,IprsIseInterface*()(const char)) at line 101 in file "" ($t1)
could not read "ProcessIseInterface.C"
(/usr/bin/dbx) func
IprsIseInterface::execute(int,char**,IprsIseInterface*()(const char))

********************************************************

dbx is part of the AIX operating system and thus could be used without additional costs (fileset bos.adt.debug). Any chance to have it installed?

To Shockneck ...

if we have dbx , is it possible to debug the executable with out changing the source code ? .. because i dont have much idea abt core_dump n dbx .. is dbx used to identify the problem or resolving the problem ?

Dbx is mainly for identifying problems in your code by running it line by line but it can also be used to change variables. However, AFAIK the program you want to debug needs to be compiled with the -q option if using dbx should make much sense. You can use it without but the possibilities will be limited then. Have a look in the dbx manpage for a start.

lemme try ... we transfered the core file to another machine which having dbx n ran some commands ... the output is pasted below ...

(/usr/bin/dbx) where
ustart() at 0x9fffffff0000240
(/usr/bin/dbx) step
stopped in IprsIseInterface::execute(int,char**,IprsIseInterface*()(const char)) at line 101 in file "" ($t1)
could not read "ProcessIseInterface.C"
(/usr/bin/dbx) func
IprsIseInterface::execute(int,char**,IprsIseInterface*()(const char))

***************************************************************
???? anyone can get any idea about the problem in the code ?
