If an application attempts to put a ‘REQUEST-type’ message on a queue, what field in the MQMD does the queue manager check to be sure it has a value?
Ans: ReplyToQ
1.If the client application is running on on machine and moved to another then what is the attribute need to set.
2.Qmgr Q1 in london and Qmr2 in paris forms a cluster. for adding Qmgr3 in washington into the cluster how many more channels need to be created in Qmgr1 and Qmgr2?
3. When the 2 repositories go down what happens to other queue managers in the cluster.
4. two channel are defined with same xmitq, when one channel is started what happens when you try to start the other.
5. To find out the status of a remote queue manager what command is used?
6. Which exit is used to check if the user is trusted party?
7. Two applications running on a Queumanagers are connected to 2 remote Queue managers via two Xmit Queueus. Channels are running at ful capacity. How can we increase the perfomance?
8. An event message is generated in Qmgr1 and even messages are monitored by Qmgr2. Expiration time of even message is 1 min. the link frm qmgr1 and qmgr2 is down. What happens to the message?
9. MQGET fails and the message is still in the Queue. What command is used to find the error caused?
10. Three Qmgrs Q1 Q2 Q3. There is no connection between Q1 and Q2. A message is put into Q1 and it has to reach Q3 via Q3.(Multi Hopping) Now the lnk between Q2 and Q3 is down. What happens to the message.
11. Command USed to find the message length?
12. which installable service component can be used for security?
13. channels defined btwn qm1 and qm2 are qm1.t.qm2 & qm2.t.qm1. how to know the link status

1. How do you define when a message on a Queue to be shared on Qmanagers QM1, QM2 and QM3?
2. A person wants to define a Controlled Queue Manager, which will be used to control objects on other Client Queue managers which one will mention the best realtionship between Controlled ueue manager and Client Queue manager?
3. When a channel is running, if it fails suddenly, what command u use to roll the back the messages which are in Transmission Queue?
4. When we try to put a message on a Queue and if it fails, with saying as Queue is in use. Which command u use to find which application uses this Queue?
5. What is the command in Unix to direcly run the Channel?
6. If the channel has to stop after 1hour how do u define Disconnect interval?
7. If the AIX appilcation sends a message to Windows application where do u specify a convert option?
8. If MQseries wants to know the conversation obtained by Sending application sends a message to Server, which option you use in message descriptor?
9. When a message sending from one channel to another and if the message needs to be changed in header of the message where do u change it?
10. If a channel is defined with TCP then which field will tell you the TCP value?
