This information supports z/OS® (5650-ZOS).
Purpose of this information:
This information provides information for debugging JES3 and installation-written
extensions of JES3. It describes the tools that JES3 users can use
for debugging. This information is specifically designed for installations
running z/OS.
Who should read this information:
This information is intended for system programmers and IBM® service
representatives or anyone who is responsible for diagnosing and correcting
problems in JES3. Users of this information must have a working knowledge
of JES3 functions.
How to use this information:
This information contains information used by the system programmer
for diagnosing JES3 problems.
This information is divided into the following topics:
- Diagnosing, Resolving, and Reporting JES3 Problems
Discusses a general
methodology for diagnosing JES3 problems and includes topics about:
- Collecting an exact description of the problem.
- Gathering relevant system supplied data.
- Determining the system's status.
- Publications that assist in diagnosis.
- Recommendation for using JES3 dumps and Dump Core.
- Viewing the contents of a dump
- Viewing the JES3 control blocks
- Types of problems in JES3 and associated address spaces.
- Abends in JES3 address spaces
- Miscellaneous JES3 problems areas
- JES3 system abends in user address space
- Problems in the FSS address space
- Problems in the JES3DLOG address space
- Problems in the JESXCF address space
- Problems in the BDT address space
- Typical JES3 problems and their resolution
- Job related diagnosis
- Reporting a problem to IBM.
- General Diagnosis
Discusses facilities
and tools used for general system diagnosis. This discussion includes
the format of trace tables and use of JES3 diagnostic facilities,
such as descriptions of:

Discusses how to identify
areas in a formatted dump of a JES3 or C/I Functional Subsystem (FSS).
- JES3 Monitoring Facility
Provides a description
on how system programmers can use the JES3 Monitoring Facility (JMF)
to obtain statistical data of the system.
- Reading a JMF hardcopy report
Provides a description
of the JMF hardcopy report and a description of how to generate a
report using SMF records.
