JMS and websphere 30/1/2014
you want to use JMS:
1. Read the relevant sections of the MQ Using Java manual. 2. Also skim the first several sections of the MQ Publish/subscribe manual.
If you want to use C programs:
1. take an hour or two (really, that's all it will take) to read the first several sections of the MQ Publish/Subscribe manual - don't read all the reference material in there, you can come back to that another time. 2. use the supplied Publish/subscribe sample programs to teach yourself by example.
Enjoy

WELCOME TO MY WORLD , MQ .
Facing the monster .
Reach with kindness . Kind words , Kind deed .
Turn the monster turn into small bits and they disappear .
Overcome anger eating demon in life with kindness.

recieving channel
sending channel
MQI channel
A Message Queue Interface (MQI) channel connects a WebSphere
MQ client to a queue manager across a network. An MQI channel is
bidirectional in that one channel can be used for a client to both send
and receive messages. The two subtypes of MQI channel are SVRCONN
(a definition used by the queue manager) and CLNTCONN (a definition
used by the client program)

Messages
WebSphere MQ Message Descriptor (MQMD): Identifies the message and contains
additional control information, such as the type of message and the priority that is
assigned to the message by the sending application.
Message properties: An optional set of user-definable elements that describes the
message without being part of the payload. Applications that receive messages can
choose whether to inspect these properties.
Message data: Contains the application data. The structure of the data is defined by the
application programs that use it; WebSphere MQ is largely unconcerned with its format or
content.
Message descriptor (MQMD)
The MsgType describes the high-level purpose of the message.
The most frequently used values in this field are datagram,
request, reply, and report.
A datagram is set by the sending application when it is not
expecting any response from the receiving application.
MsgID (message ID) and CorrelID (correlation ID) are used to identify a specific request
or reply message.
The programmer can set a value in one or both fields or have
WebSphere MQ automatically create a unique ID. These fields are 24 bytes long and are
not treated as characters that can be converted between code pages, such as ASCII to
EBCDIC.
A normal pattern for application programs is that the message ID that is generated by
WebSphere MQ when a message is put to a queue is used to identify responses sent
back to the designated reply queue. The program that receives the request message
copies the incoming message ID into the correlation ID of the reply message. This allows
the originating program (the one that gets the reply) to instruct the queue manager to
return a specific message in the reply queue instead of just getting the first message from
the queue. It is particularly important when multiple applications are reading messages
from the same queue.
The Persistence flag selects whether the message must be treated as persistent, and
therefore recoverable in a system failure, or whether the message is non-persistent and
can be discarded when an error occurs. A programmer can explicitly set persistence to be
on or off, or allow the value to be controlled by a system administrator.
Queues can hold a combination of persistent and non-persistent messages
Messages have a Priority that is set as a value between 1 and 10. An administrator can
define that messages are retrieved in priority order, rather than true first in first out (FIFO)
sequencing.
the PutTime and PutDate
Messages might have Expiry time.
When sending a request message, the responding application must be told where to send
the reply. This is usually done by providing the ReplyToQ and ReplyToQMgr names in the
initial request.
The Format field describes the message data. It is often set to MQSTR (to denote text
data) or NONE (to denote binary data), but there are other possible values. In some
cases, the body of the message is itself made up of additional WebSphere MQ-defined
structures and the format field tells WebSphere MQ what to do with that data.
User-defined formats can also be used. The format setting causes data conversion to take
place when it is needed. For example, it causes WebSphere MQ to convert text data
between ASCII and EBCDIC code pages (the CodedCharSetId field) when the sending
and receiving applications are on different systems using those character sets
information about the sending application (program name and path) and the platform on
which it is running are set in the PutApplType and PutApplName fields
Each time a message is backed out, the BackoutCount is increased. An application can
check this counter and act on it, for example, send the message to a different queue where
the reason for the backout is analyzed by an administrator.
Messages can be sent as part of a related group. The receiving application can then wait
until all messages from the group have arrived before starting its processing. Message
grouping also guarantees that the order in which the messages are sent is preserved. The
GroupId and MsgSeqNumber fields in the MQMD define this processing.
Message properties
The most important objects from this set are queues, channels,
topics, and the queue manager itself.
Queue manager
It is the queue manager that manages the storage of data and the recovery after a failure. The
queue manager coordinates all the applications updating messages on queues, and deals
with the isolation and locking that are required to maintain consistency. The queue manager
maintains statistics and status information for reporting, as needed.
qUEUE
LOCAL queue = p;ace where message are physically store
Alias Queue = pointer to a local queue
remote queue = A remote queue is another type of pointer. A remote queue definition
describes a queue on another queue manager. When an application
opens a remote queue, the queue manager to which the application is
connected ensures that messages are tagged and stored locally in
preparation for sending to another queue manager. Applications
cannot read messages from remote queues
Model queue - Used by application to dynamically create a real queue . Use to create a unique for reply messages
deleted when application end .
Dynamic queue - queues are created by the process of opening a model queue.
They are real local queues, but they cannot be explicitly created
through administration interfaces.
There are two subtypes of dynamic queue: A temporary dynamic
queue (TDQ) is automatically deleted when the application that caused
it to be created ends. A permanent dynamic queue (PDQ) survives the
creating application and can be reused by another application
Special queue
Transmission queue
local queue with the USAGE(XMITQ) attribute
configured.
It is a staging point for messages that are destined for a
remote queue manager.
Typically, there is one transmission queue for
each remote queue manager to which the local queue manager might
connect directly.
If the destination is unavailable, messages build up
on the transmission queue until the connection can be successfully
completed.
Transmission queues are transparent to the application.
When an application opens a remote queue, the queue manager
internally creates a reference to the relevant transmission queue and
messages are put there
Initiation queue
An initiation queue is a local queue to which the queue manager writes
a trigger message when certain conditions are met on another local
queue. For example, this is done when a message is put into an empty
message queue or in a transmission queue. Such a trigger message is
transparent to the programmer, but it is a powerful mechanism to
cause applications or channels to start executing only when there is
work to be processed. For more information about how this process
works, see 3.5, “Triggering” on page 39
A dead-letter queue (DLQ) is usually defined when a queue manager
is created. It is used for situations when a queue manager cannot
deliver a message across a channel. Here are some examples:
The destination queue is full.
The destination queue does not exist.
Message puts have been inhibited on the destination queue.
The sender is not authorized to use the destination queue.
The message is too large
When these conditions are met, the messages are written to the DLQ.
A queue manager has at most one DLQ.
Messages are only sent to the DLQ after they have successfully been
put to a local transmission queue first.
If an application putting a message receives an error that indicates the
output queue is full, the message is not put to a DLQ. The message is
never accepted by the queue manager for processing.
Events queue The queue manager generates event messages when certain things
happen. For example, events can occur when a queue is nearly full or
when an application is not authorized to open a queue. These event
messages are written to one of the predefined event queues and can
then be processed by management tools. All event queues have
similar names that indicate the type of event that is held there.
SYSTEM.ADMIN.QMGR.EVENT or SYSTEM.ADMIN.CHANNEL.EVENT are
examples of queue manager event queues

WEB SPHERE Topology
hen it comes to WebSphere MQ there's (almost) no such thing as an initial tutorial. First you must understand the basic concept of message oriented middleware and the way it's implemented in WMQ.
First you should take a look at this document:
http://www.redbooks.ibm.com/abstracts/redp0021.html (MQ Series Primer)
After this book you can consult "WebSphere MQUsing Java Version 6.0"
http://www.elink.ibmlink.ibm.com/publications/servlet/pbi.wss?CTY=US&FNC=SRX&PBL=SC34659102
And THE place to look when you have questions regarding WMQ and Java programming:
