Ibm Integration Bus Placement Papers - Ibm Integration Bus Interview Questions and Answers updated on 27.Jul.2024

Q1. Mqinput Node And Input Node Differences?

You must use an Input node to provide the in terminal to a subflow.

The Input node provides an in terminal for an embedded message flow (a subflow).

Q2. Difference Between Rad And Ordinary Deployment?

Using Resource adapter deployment, we can reuse the deployment till the server is rebooted.

Q3. How To Configure Mq?

By using runmqsc <Qmanager> command.

Q4. Define Correlation Names?

A correlation name is a field reference that identifies a well-defined starting point in the logical message tree and is used in field references to describe a standard part of the tree format.

Q5. What Is The Role Of Configuration Manager?

Connecting to the broker and to deploy the message flows.

Q6. Can We Create Multiple Instances Of A Message Flow?

Yes we can. One way is by adding multiple node. For ex. A single message flow can handle DATA received across MQ and Messages that are received across native IP connections.

Q7. What Are Mq Commands?

  • CRTMQM
  • STRMQM
  • DLTMQM
  • ENDMQM

Q8. Mq Objects?

Queue manager , Send queue ,Receive queue ,Administration queue, Administration queue ,Restart queue  ,Spill queue.

Q9. How Can We See The Error Log Files In Broker?

The Windows Event Viewer is where WebSphere Message Broker writes records to the local system.

Q10. Performance Monitoring Tools?

WebSphere Application Server , Java Management Extensions (JMX).

Q11. Mqsi Server, Mqsi Client Difference? How To Connect These Two Through Command Prompt?

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

Q12. Difference Between Mqconn And Mqconnx?

MQCONN (MQSTATE, qManagerName) : Connects to a queue manager, which is identified by qManagerName, a string of up to 48 characters. MQSeries sets the connection handle for use in subsequent calls.

MQCONNX (MQSTATE, qManagerName, MQCNO): Connects to a queue manager with options that control the way that the call works. The queue manager is identified by qManagerName, a string of up to 48 characters. MQSeries sets the connection handle (MQSTATE.hconn) for use in subsequent calls.

Q13. Use Of Configmanager?

To deploy the message flows onto the Broker.

Q14. Difference Between Root And Output Root?

Root is used in the Database content changing  and in Filter node.

Output Root is used in the ESQL code for a Compute node that creates a new output message based on the input message.

Q15. Define Broker, Bar, Execution Group, Scada, And Components Of Broker?

BROKER: A broker is a set of execution processes that hosts one or more message flows to route, trform, and enrich inflight 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 Trport. 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. The node also establishes the processing environment for these messages.

COMPONENTS OF BROKER: Broker, Configmgr, User name service.

 

Q16. What Is Eai? What Are Those Tools?

Enterprise Application Integration refers to the integration of one or more applications and processes together.

Tools: WBI Message Broker, ICS, WebMethods and Tibco

Q49. Difference Between Mqput And Mqput1?

MQPUT(MQSTATE, MQMD, MQPMO, BUFFER) : Adds a message to the queue. The buffer cannot be more that 32767 bytes, but that restriction does not apply if you are using the EGL add statement.

MQPUT1(MQSTATE, MQOD, MQMD, MQPMO, BUFFER): Opens a queue, writes a single message, and closes the queue

Q50. Difference Between Mca And Mqi Channels?

A message channel connects two queue managers via message channel agents (MCAs). Such a channel is unidirectional. It comprises two message channel agents, a sender and a receiver, and a communication protocol. An MCA is a program that trfers messages from a trmission queue to a communication link, and from a communication link into the target queue. For bidirectional 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 bidirectional.
