Abstract

Disclosed is a graphical display of the relationships between the various processes running in an OS/2* 2.0 system. The relationships shown are those maintained by the OS/2 kernel.

Displaying Information about OS/2 Processes

       Disclosed is a graphical display of the relationships
between the various processes running in an OS/2* 2.0 system.  The
relationships shown are those maintained by the OS/2 kernel.

      This program is an analysis tool which determines and displays
all processes running on a OS/2 2.0 system.

      This program uses the Per Task Data Areas (PTDAs) to determine
what processes are active and their relationships. (Other programs
have "discovered" the relationships by looking at only the "parent"
of the particular process.  The actual genealogy as maintained by the
OS/2 kernel is used.) It starts with the system process and
determines if it has any child processes.  It continues down each
path looking for more child processes, adding them to the list being
built.  After completing the process search, it displays the list in
a tree structure.

      The display is similar to:

      The determination and presentation of the process hierarchy of
an OS/2 2.0 system is provided by this program. No other program or
tool presents this information in such a clear and concise way.
