This book has the following parts:
- Part 1, Introduction
- Introduces the concepts of WebSphere MQ intercommunication.
This part of the book introduces WebSphere MQ intercommunication.
The description in this part is general, and is not restricted to a particular
platform or system.
- Note:
- Some references are made to individual WebSphere MQ products. Details
are given only for the products that this edition of the book applies to (see
the edition notice for information about which WebSphere MQ products these
are).
- Part 2, How intercommunication works
- Describes the functions performed by the distributed-queuing management
(DQM) facilities. Read this part to understand DQM's role in the
context of WebSphere MQ.
- Part 3, DQM in WebSphere MQ for UNIX systems, and Windows systems, and MQSeries for Compaq OpenVMS Alpha, Compaq NonStop Kernel, and OS/2 Warp
- Is specific to WebSphere MQ products on distributed platforms. It
helps you to install and customize DQM on these platforms. It explains
how to establish message channels to other systems and how to manage and
control them.
- Part 4, DQM in WebSphere MQ for z/OS
- Is specific to WebSphere MQ for z/OS. It helps you to install and
customize DQM. It explains how to establish message channels to other
systems and how to manage and control them.
- Part 5, DQM in WebSphere MQ for iSeries
- Is specific to WebSphere MQ for iSeries. It helps you to install
and customize DQM. It explains how to establish message channels to
other systems and how to manage and control them.
- Part 6, DQM in MQSeries for VSE/ESA
- Is specific to WebSphere MQ for VSE/ESA(TM). It contains an example
of how to set up communication to other systems.
- Part 7, Further intercommunication considerations
- Tells you about channel exit programs, which are an optional feature of
DQM that allow you to add your own facilities to distributed queuing.
It gives some guidance on the problems you may experience, how to recognize
these problems, and what to do about them.
- The Appendixes
- contain extra information that is pertinent to DQM:
Appendix A, Constants for channels and exits gives the values of named constants that apply to the
channels and exits in the MQI that are discussed in this book.
Appendix B, Queue name resolution provides a detailed description of name resolution by queue
managers. You need to understand this process in order to take full
advantage of DQM.
Appendix C, Configuration file stanzas for distributed queuing gives information about the configuration file stanzas that
relate to distributed queuing.
This book uses the following type styles:
- CompCode
- Example of the name of a parameter of a call
In the body of this book, the following shortened names are used:
- CICS(R)
- The CICS Transaction Server for z/OS(R) (CICS/Enterprise Systems
Architecture) product. (Note that, unlike other WebSphere MQ books,
this book does not use the term generically to include other CICS products
such as CICS for VSE/ESA.)
- OS/2
- OS/2 Warp
- z/OS
- z/OS means any release of z/OS or OS/390 that supports the current version
of WebSphere MQ for z/OS.
The term "UNIX systems" is used to denote the following UNIX operating
systems:
- AIX
- AT(R)&T GIS UNIX
- Compaq Tru64 UNIX
- HP-UX
- SINIX and DC/OSx
- Sun Solaris (SPARC and Intel Platform Editions)
Throughout this book, the name mqmtop has been used to represent the name
of the base directory where WebSphere MQ is installed on UNIX systems.
- For AIX, the name of the actual directory is /usr/mqm
- For other UNIX systems, the name of the actual directory is
/opt/mqm
