Abstract

Disclosed is a method of improved problem determination following a failure somewhere in an MRO/HPCS (Multiple Region Operation/Highly Parallel Coupled System) connected system environment where an application is distributed across several MVS (Multiple Virtual Storage) regions. The requirement is to capture all potentially relevant documentation at failure time. The described improvement allows documentation to be captured only from those regions actively involved rather than the total number of all MVS regions comprising the system. Without this innovation first failure data capture would be limited to the region suffering the failure, making problem resolution very difficult.

Multiple Address Space First Failure Data Caputre

      Disclosed is a method of improved problem determination
following a failure somewhere in an MRO/HPCS (Multiple Region
Operation/Highly Parallel Coupled System) connected system
environment where an application is distributed across several MVS
(Multiple Virtual Storage) regions.   The requirement is to capture
all potentially relevant documentation at failure time.  The
described improvement allows documentation to be captured only from
those regions actively involved rather than the total number of all
MVS regions comprising the system.   Without this innovation first
failure data capture would be limited to the region suffering the
failure, making problem resolution very difficult.

      In an MRO/HPCS connected system environment, problem resolution
will require documentation from each of the connected systems.   A
task may involve a TOR,AOR,FOR (Terminal, Application and File Owning
Regions), possible additional AORs via DPL (Distributed Program
Link), and a database manager across multiple MVS images.   In order
to resolve problems, information from each of the connected regions
may be required.  To obtain the correct documentation, a means of
identifying all regions associated with a given CICS region is
required.   This information will then be used to initiate an SDUMPX
which has the ability to issue dumps across MVS images, within a
system complex.  This would include the associated CICS...
