Java™

There are two ways of inquiring on a queue: inquire and inquireAll.

InquireAll will return a Fields object in the admin reply message.

/* Create an empty queue admin message and parameters field*/
 MQeQueueAdminMsg msg = new MQeQueueAdminMsg();

/*Prime message with who to reply to and a unique identifier      
 * Set the admin action to get all characteristics of queue manager.
 */
msg.inquireAll(new MQeFields());

/* get message back from the admin reply queue to match */
/* and retrieve the results from the reply message */

The fields object that is returned in the administration reply message is populated with all of the properties of the queue. To get access to a specific value use the field labels as in the property table above. For example, to get at the queue description, assuming respMsg is the administration reply message:

// all on one line:
String description = respMsg.getOutputFields().
    getAscii(com.ibm.mqe.administration.Queue_Description)

Instead of requesting all the properties of a queue, particular ones can be requested and returned. If, for example, only the description is required the following can be used:

MQeFields requestedProperties = new MQeFields();
requestedProperties.putAscii(Queue_Description);
msg.inquire(requestedProperties)

/* Retrieve the administration reply */ 
/* message from the relevant queue */
/* Then retrieve the returned MQeFields */
/* object from this message */
MQeFields  outputFields = respMsg.getOutputFields();

outputFields now contains the field Queue_Description only.
