An Introduction to MQSeries Messaging and Queuing

IBM WebSphere MQSeries allows different applications to communicate asynchronously through queues across different operating systems, different processors, and different application systems.WebSphere MQSeries includes the Message Queue Interface (MQI), a common low-level programming application program interface (API). Applications use MQI to read and write messages to the queues.

What is MQSeries?

A middleware product that implements a messaging and queuing framework.

Middleware - an intermediate software component that bridges dissimilar computing environments.

Messaging - programs communicate by sending data in messages rather than by calling each other directly.

Queuing - messages are put on queues in storage, eliminating the need for programs to be logically connected.

A messaging and queuing framework is inherently ASYNCHRONOUS!

MQSeries Objects

1.1 Queue Manager

A queue manager is that part of an MQSeries product that provides the messaging and queuing services to application programs, through the Message Queue Interface (MQI) program calls. It controls access to queues and serves as transaction (sync point) coordinator for all queue operations.

Queue manager names must be unique!

1.2 Queues

MQSeries defines four types of queues. A queue instance is fully qualified by its queue manager and queue name.

Local Queue - an actual queue for which storage is allocated.

Remote Queue - a definition of a queue on a different queue manager (acts somewhat like a pointer)

Alias Queue - another name for a local or remote queue. Typically used to switch queue destinations without modifying program code

Model Queue - a template whose properties are copied when creating a new dynamic local queue (create queue xxx like queue yyy).

Some properties of local queues:

Maximum Message Size Maximum Queue Depth High/Low Factors Enable/Disable Put or Get Persistent/Not Persistent

1.3 Channels

A channel provides a communication path between Queue Managers.

1.4 Messages

A message any arbitrary data that one program wants to send to another. This data is called the application data.

A message needs to include other information, such as its destination and possibly a return address. This type of data is called the message descriptor

There are four types of messages:

1. A request message is used by one program to ask another program for something (usually data). A request message needs a reply.

2. A reply message is used in response to a request message.

3. A one-way message, as you would expect, doesnt need a reply, though it can carry data.

4. A report message is used when something unexpected occurs. For example, if the data in a reply message is not usable, the receiving program might issue a report message.

Most useful report messages are generated by the Queue Manager. For example, Delivery confirmation.

Messages can have a time-to-live, called Expiry. A message that has not been delivered before its expiration is removed (not given to an app)

What to do with undeliverable messages? Each queue manager can have a dead-letter queue.

Messages can be individually designated persistent or non-persistent (persistent messages are logged to enable recovery)

Message Correlator - select which message to get from queue

Message Priority - retrieve messages in different order of put

Segmented Messages - allows ending of VERY LARGE messages (> 100 MB)

A message can contain a reply to address (the name of a Queue Manager and Queue). This tells the receiving application where any response should be sent.

Messages are added and removed from queues in Units of Work

The smallest Unit of Work is one message.

Units of work are atomic.

When an app reads a message from a queue, a message appears to have been removed, but in fact, it is still in storage until the app commits the unit of work.

1.5 Pic: Message Flow Between Applications

Frequently used APIs in Application Programs

(MQI The MQSeries Programming Interface)

MQCONN Connect to queue manager MQDISC Disconnect from queue manager MQOPEN Open object MQCLOSE Close object MQPUT Put message MQPUT1 Put one message MQGET Get message MQBEGIN Begin unit of work MQCMIT Commit MQBACK Back out MQINQ Inquire about object attributes MQSET Set object attributes

1.6 Need for API:

The MQ Series client code that runs in the client machine processes the API calls and routes them to the machine defined in the environment variable.

The application program can put many messages in the queue before it closes or gets disconnected.

COBOL MQ

API Commands sequence for Sending MQ Messages

Step 1: The MQCONN call connects an application program to a queue manager. It provides a queue manager connection handle, which is used by the application on subsequent message queuing calls.

Syntax : MQCONN (QMgrName, Hconn, CompCode, Reason)

QMgrName (MQCHAR48) input Name of queue manager.Hconn (MQHCONN) output Connection handle.CompCode (MQLONG) output Completion code. Reason (MQLONG) output Reason code qualifying CompCode.

Step 2: The MQOPEN call establishes access to an object.

Syntax : MQOPEN (Hconn, ObjDesc, Options, Hobj, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.ObjDesc (MQOD) input/output Object descriptor.Options (MQLONG) input Options that control the action of MQOPEN.Hobj (MQHOBJ) output Object handle.CompCode (MQLONG) output Completion code.Reason (MQLONG) output Reason code qualifying CompCode.

Step 3: The MQPUT call puts a message on a queue or distribution list. The queue or distribution list must already be open.

Syntax : MQPUT (Hconn, Hobj, MsgDesc, PutMsgOpts, BufferLength, Buffer, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.Hobj (MQHOBJ) input Object handle.MsgDesc (MQMD) input/output Message descriptor.PutMsgOpts (MQPMO) input/output Options that control the action of MQPUT.BufferLength (MQLONG) input Length of the message in Buffer.Buffer (MQBYTEBufferLength) input Message data.CompCode (MQLONG) output Completion code.Reason (MQLONG) output Reason code qualifying CompCode.

Step 4: The MQCLOSE call relinquishes access to an object, and is the inverse of the MQOPEN call.

Syntax : MQCLOSE (Hconn, Hobj, Options, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.Hobj (MQHOBJ) input/output Object handle.Options (MQLONG) input Options that control the action of MQCLOSE.CompCode (MQLONG) output Completion code.Reason (MQLONG) output Reason code qualifying CompCode.

Step 5: The MQDISC call breaks the connection between the queue manager and the application program, and is the inverse of the MQCONN or MQCONNX call.

Syntax : MQDISC (Hconn, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.CompCode (MQLONG) output Completion code.Reason (MQLONG) output Reason code qualifying CompCode.

API Command sequence for Receiving MQ Messages

Step 1: The MQCONN call connects an application program to a queue manager. It provides a queue manager connection handle, which is used by the application on subsequent message queuing calls.

Syntax : MQCONN (QMgrName, Hconn, CompCode, Reason)

QMgrName (MQCHAR48) input Name of queue manager.Hconn (MQHCONN) output Connection handle.CompCode (MQLONG) output Completion code. Reason (MQLONG) output Reason code qualifying CompCode.

Step 2: The MQOPEN call establishes access to an object.

Syntax : MQOPEN (Hconn, ObjDesc, Options, Hobj, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.ObjDesc (MQOD) input/output Object descriptor.Options (MQLONG) input Options that control the action of MQOPEN.Hobj (MQHOBJ) output Object handle.CompCode (MQLONG) output Completion code.Reason (MQLONG) output Reason code qualifying CompCode.

Step 3: The MQGET call retrieves a message from a local queue that has been opened using the MQOPEN call.

Syntax : MQGET (Hconn, Hobj, MsgDesc, GetMsgOpts, BufferLength, Buffer, DataLength, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.Hobj (MQHOBJ) input Object handle.MsgDesc (MQMD) input/output Message descriptor.GetMsgOpts (MQGMO) input/output Options that control the action of MQGET.BufferLength (MQLONG) input Length of the message in Buffer.Buffer (MQBYTEBufferLength) input Message data.CompCode (MQLONG) output Completion code.

Step 4: The MQCLOSE call relinquishes access to an object, and is the inverse of the MQOPEN call.

Syntax : MQCLOSE (Hconn, Hobj, Options, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.Hobj (MQHOBJ) input/output Object handle.Options (MQLONG) input Options that control the action of MQCLOSE.CompCode (MQLONG) output Completion code.Reason (MQLONG) output Reason code qualifying CompCode.

Step 5: The MQDISC call breaks the connection between the queue manager and the application program, and is the inverse of the MQCONN or MQCONNX call.

Syntax : MQDISC (Hconn, CompCode, Reason)

Hconn (MQHCONN) output Connection handle.CompCode (MQLONG) output Completion code.Reason (MQLONG) output Reason code qualifying CompCode.

Note: CICS programs do not have to issue MQCONN and MQDISC commands. The programs are connected automatically to the queue manager to which the CICS system is connected.
