I have a requirement to be able to remove subscriptions with a
"RegistrationUserIdentifier" other than "mqm". The application sending the DeReg command to the broker is connecting using a bindings connection and is running as mqm.
Prior to securing our mq installation, everything connected as mqm so the RegistrationUserIdentifier was always mqm. This meant we could run a utility to send a DeReg command and it would always work.
Now, we are in a situation where some applications are registering subscriptions without the MQREGO_VARIABLE_USER_ID option. As such we cannot remove them with a utility running as mqm.
I'm looking to rectify this situation by modifying the utility to set the userid to the registered userid by using the following code:
| Code: |
MQEnvironment.userID = userid;
qMgr = new MQQueueManager(qMgrName);
System.out.println("\nQueue manager name: " + qMgrName);
brokerQueue = qMgr.accessQueue(commandQueue,
(MQC.MQOO_OUTPUT | MQC.MQOO_ALTERNATE_USER_AUTHORITY), "", "",
userid);
....
MQMessage requestMsg = new MQMessage();
MQPutMessageOptions pmo = new MQPutMessageOptions();
pmo.options = MQC.MQPMO_NEW_MSG_ID | MQC.MQPMO_ALTERNATE_USER_AUTHORITY;
requestMsg.userId = userid;
brokerQueue.put(requestMsg, pmo);
|
However, what i'm finding with the above code is that despite running as mqm, I receive 2035 errors and a failure to connect to the queue manager:
| Code: |
Event command (44) = Queue manager event
Event reason (2035) = Not authorized
Queue Manager name (2015) = RETAIL_JMS_MALI_MGR
Reason Qualifier (1) = MQRQ_CONN_NOT_AUTHORIZED
User Identifier (3025) = mqm
Application name (3024) = java
|
The platform details are:
WebSphere MQ 6.0.2.7 on Solaris SPARC. Unsubscribe utility is a java 1.5 application using the standard mq java api to manually construct messages to dereg subscriptions. |
