5. Define BROKER, BAR, EXECUTION GROUP, SCADA, and COMPONENTS OF BROKER, WORKBENCH, WORKSPACE, and CMM?
Ans.
BROKER: A broker is a set of execution processes that hosts one or more message flows to route, transform, and enrich in-flight messages.
BAR: Flows and sets that are to be deployed are packed in it and sent to configuration manager
EXECUTION GROUP: An execution group is a named grouping of message flows that have been assigned to a broker. The broker enforces a degree of isolation between message flows in distinct execution groups by ensuring that they execute in separate address spaces, or as unique processes.
SCADA: The SCADAInput node is used to receive messages from clients that connect to the broker across the WebSphere MQ Telemetry Transport. SCADA device clients use the MQIsdp protocol to send messages, which are converted by the SCADAInput node into a format recognized by WebSphere Message Broker.

It comprises two message channel agents, a sender and a receiver, and a communication protocol. An MCA is a program that transfers messages from a transmission queue to a communication link, and from a communication link into the target queue. For bi-directional communication you have to define two channel pairs consisting of a sender and a receiver.
A Message Queue Interface (MQI) channel connects an MQSeries client to a queue manager in its server machine. Clients don’t have a queue manager of their own. An MQI channel is bi-directional.

35. MQSI Server, MQSI Client difference? How to connect these two through command prompt?
Ans.
MQSeries Client:
A client workstation does not have a queue manager of its own. It shares a queue manager in a server with other clients. All MQSeries objects, such as queues, are in the server. Since the connection between client and server is synchronous, the application cannot work when the communication is broken. You could refer to such workstations as "slim" clients.
MQSeries Server:   
A workstation can be a client and a server. A server is an intermediate node between other nodes. It serves clients that have no queue manager and manages the message flow between its clients, itself and other servers. In addition to the server software you may install the client software, too. This configuration is used in an application development environment
 
Connection:    strmqm QMA
Start runmqlsr -t tcp -m QMA -p 1414
Runmqsc
Start channel (QMA.QMB)
End

61. Aggregate nodes?
Ans.  Aggregation nodes are used in fan-out and fan-in process.
Fan-out: The initial request to the message flow, representing a collection of related requested items, is split into the appropriate number of individual requests to satisfy the subtasks of the initial request.
Fan-in:  Replies from the subtasks are combined and merged into a single reply that is returned to the original requester (or another target application) to indicate the completion of the processing.
WebSphere Message Broker provides three message flow nodes that support aggregation:

118. What is the difference between catch terminal and failure terminal in MQInput node?
Ans.
Catch terminal: The output terminal to which the message is routed if an exception is thrown downstream and caught by this node.
Failure terminal: failure terminal detects an internal error; it propagates the message to that terminal.
The output terminal to which the message is routed if an error occurs. Even if the Validation property is set, messages propagated to this terminal are not validated.

119. How to specify reference keyword in the ESQL and what is the use of it?

Ans. The Tagged/Delimited String format (TDS) is the physical representation of a message that has a number of data elements separated by tags and delimiters.
Custom Wire Format (CWF) is the physical representation of a message that is composed of a number of fixed format data structures or elements, which are not separated by delimiters

123. Command used to deploy?
Ans. Using mqsideploy

124. What should you do before creating the broker and the configuration manager?
Ans. We have to create the data source name and Queue manager

125. Explain about web services nodes?
Ans. WebSphere MQ Web Services Transport connects Web services and clients that use the HTTP protocol for messaging. A WSDL definition for that service can be imported into a message set using the new WSDL importer.
HTTPInput: This node to receive Web service requests for processing by a message        flow Use the HTTPRequest node to interact with a Web service
SET OutputRoot.HTTPResponseHeader = NULL;
HTTPReply: This node to return a response from the message flow to the Web service client.
Select the Ignore Transport Failures check box if you want transport-related failures to be ignored (for example, if the client is disconnected). If you clear the check box, and a transport-related error occurs, the input message is propagated to the failure terminal. If you clear the check box, you must supply a value for Reply send timeout.
Set the Reply send timeout value if you are not ignoring transport failures. This is the length of time that the node waits for an acknowledgment that the client has received the reply.

126. Explain about JMS nodes?
Ans. JMS Input Node: to receive messages from JMS destinations.
The JMSInput node receives and propagates messages with a JMS message tree. You can set the properties of the JMSInput node to control the way that the JMS messages are received. JMS Output Node: to send messages to JMS destinations

127. Process of clustering and what are the advantages of clustering?
Ans. Grouping up of two or more Queue managers
Advantages: load balancing, reduces network traffic

128. Working of XML Transformation node?
Ans. Used to transform an XML message to another form of XML message, according to the rules provided by an XSL (eXtensible Stylesheet Language) style sheet.
You can use node properties. This ensures that the transformation defined by this single style sheet is applied to every message processed by this node.
You can use the content of the XML data within the message itself. This transforms the message according to a style sheet that the message itself defines. This behavior is only available for XSL and XML files that are located within a Message Flow project.
You can set a value within the LocalEnvironment folder associated with the message. This provides a dynamic choice of style sheet, because you must set this value (in a Compute node) within the message flow after receipt of the message. You can therefore use a variety of inputs to determine which style sheet to use for this message, such as the content of the message data or a value in a database.

129. Configuration of HTTP Input Node?          
Ans.
HTTP INPUT Node:
In URL Selector, put the path part of the URL from which this node receives Web service requests. Do not give the full URL.
Enter the Maximum client wait time timeout interval, as a number of seconds. This is the length of time that the TCP/IP listener that received the input message from the Web service client waits for a response from the HTTPReply node in the message flow. If a response is received within this time, the listener propagates the response to the client. If a response is not received in this time, the listener sends a SOAP Fault message to the client that indicates that its timeout has expired.
Select the Fault Format as one of SOAP 1.1, SOAP 1.2 or HTML.
If the node is to accept secure HTTP, select the Use HTTPS check box.
Select Default in the properties dialog navigator and set values for the properties describing the message domain, message set, message type, and message format that the node uses to determine how to parse the incoming message.
In the Message Domain field, select the name of the parser that you are using from the drop-down list. You can choose from:

• MRM
• XML
• XMLNS
• XMLNSC
• JMSMap
• JMSStream
• IDOC

Leave the Message Format field blank for XML, XMLNS, XMLNSC, JMS, MIME, and BLOB parsers.
Select Validation in the properties dialog navigator if you want the MRM parser to validate the body of messages against the dictionary generated from the message set. (If a message is propagated to the failure terminal of the node, it is not validated.)
Select General Message Options in the properties dialog navigator. Parse Timing is, by default, set to On Demand. This causes validation to be delayed until it is parsed by partial parsing. If you change this to Immediate, partial parsing is overridden and everything in the message is parsed and validated, except those complex types with a Composition of Choice or Message that cannot be resolved at the time. If you change this to Complete, partial parsing is overridden and everything in the message is parsed and validated; complex types with a Composition of Choice or Message that cannot be resolved at the time cause a validation failure.
Select Description in the properties dialog navigator to enter a short description, a long description, or both.
Click Apply to make the changes to the HTTPInput node without closing the properties dialog. Click OK to apply the changes and close the properties dialog. Click Cancel to close the dialog and discard all the changes that you have made to the properties.
