STACK TRACE:
The
image, a core image, or the running kernel. It also interprets and formats
control structures in the system and certain miscellaneous functions for
examining a dump.
In order to analyze the dump, you must execute the
/unix, and it must be the /unix of the system that had the problem. However, to
make any change to code, you must have the source AIX code which is not held
by customers. Therefore, there is not much more that you can do. It is best to
let the Support Center handle the dump.
One useful operation you can do is to make sure that you have a good full dump.
