A.

MQGMO_MSG_UNDER_CURSOR

B.

MQGMO_MSG_UNDER_CURSOR, MQGMO_LOCK

QUESTION 57

A new publish/subscribe application needs to be implemented. A mix of JMS and non-JMS WebSphere MQ applications will need to cooperate. It is suggested that the solution should be implemented using WebSphere MQ V8.0 rather than V7, because of the new publish/subscribe implementation of ebSphere MQ V8.0. Which of the following is NOT a benefit of the new publish/subscribe implementation in WebSphere MQ V8.0 over previous versions?

 

A.

Durable subscriptions are now supported.

B.

Message selectors and message properties can be used to further qualify subscriptions and thus reduce the number of messages received.

C.

A hierarchical system of topic based security is available and can be administered using WebSphere MQ Explorer and setmqaut commands.

D.

Topics are native WebSphere MQ objects, just like queues; new MQI calls and options are provided to give applications a more intuitive way to access these than the use of RFH2 headers.

 

Correct Answer: A

 

 

QUESTION 58

An application is using the WebSphere MQ V8.0 MQI to read a message that has been created using JMS on a WebSphere MQ V7 queue manager. How can the developer access the JMS user defined properties?

 

A.

Use the MQGMO_PROPERTIES_IN_HANDLE option and provide the MsgHandle when getting messages from a queue.

B.

Ask the administrator to set PROPCTL to COMPAT on the receiving channel, so the MQRFH2 header will be transformed into message properties.

C.

Read the whole message and parse the MQRFH2 header, because the message has been created using a previous version of the JMS API.

D.

Read the whole message and convert the MQRFH2 header using the MQMHBUF function, because the message has been created using a previous version of the JMS API.

 

Correct Answer: A

 

 

 

 

 

 

QUESTION 59

Queue Managers QMA and QMB both have a cluster queue definition for Q1. A sending application resides on QMC, which is also part of the cluster. The messages being sent from QMC contain data from the same account that needs to be processed at the destination (Q1) in the same order that the messages were sent. Which one of the following is MOST LIKELY to enforce the sending order on the destination queue, assuming the message can be routed to the destination queue?

 

A.

The sending application sends the messages for the account within the same unit of work

B.

The sending application specifies the destination Queue Manager and Queue name on the open for Q1 and sends the messages for the account

C.

The sending application opens Q1 with MQOO_BIND_ON_OPEN and sends the messages for the account

D.

Q1 is defined with DEFBIND(OPEN) and the sending application opens Q1 and sends the messages for the account

 

Correct Answer: C

 

 

QUESTION 60

A company has a large network of WebSphere MQ clustered queue managers that span multiple applications. When migrating such a cluster to a new version, which one of the following is a good practice?

A.

Perform a staged migration, in which queue managers are migrated one at a time.

B.

Stage the migration, but migrate all the queue managers on a particular operating system at the same time.

C.

At a minimum, migrate the full repositories at the same time, to avoid incompatibilities in the definitions that they store.
