One of our developers wrote an application using MQ java api and was able to connect to Queuemanager and get messages from queues. However, No autorities were given to the queue. except mqm, user no one can open or get messages from the queue.
How could the application connect to the queue manager and open queue without proper authorities..?
If we use java api calls, what user id does the program connects to the queue manager and opens the queue ?
Following is code fragment that opens the queue
*********************
MQEnvironment.port = INPUT_QUEUE_PORTNUMBER;
MQEnvironment.hostname = INPUT_QUEUE_HOSTNAME;
MQEnvironment.channel = INPUT_QUEUE_CHANNEL;
m_oMQQueueManager = new MQQueueManager(INPUT_QUEUE_MANAGER);
l_iOpenOptions = MQC.MQOO_INPUT_SHARED ;
m_oQueue = m_oMQQueueManager.accessQueue( INPUT_QUEUE_NAME, l_iOpenOptions, null, null, null);
************************ |

My guess would be that you are connecting with MQ Client - that is, somewhere there's a SVRCONN waiting for your call; most probably, you had configured MCAUSER(mqm) on the said channel.
To understand why this has the effect you described, you should read the Security and Clients manuals, and search this forum (this is a *very* frequent question); for example, when I searched for "client channel authorization" I found security and clients and many other relevant posts.
Enjoy

Actually, the Java API is the only one that does not set the user id based on the logged in user. It can't, for technical reasons.
Therefore, it by default sets the userid to null. Which unfortunately, mq treats as "mqm".
