Connecting to IBM MQ from Java client is failing with MQJE001: Completion Code '2', Reason '2035'

Question

I have a IBM MQ version 7.5 installation in windows 7. I have created a queue manager, channel and listener using the following commands.

//CREATE THE QUEUE MANAGER
crtmqm.exe PG3RT1

//START THE QUEUE MANAGER AS INTERACTIVE
strmqm.exe -si PG3RT1

//CONNECT AS SCRIPT CONSOLE
runmqsc.exe PG3RT1

//CREATE THE CHANNEL TO APPLICATION CONNECTIVITY
DEFINE CHANNEL(PG3RT1.CHANNEL) CHLTYPE(SVRCONN) TRPTYPE(TCP)

//CREATE THE LISTENER 
DEFINE LISTENER(LISTENER.PG3RT1) TRPTYPE(TCP) PORT(1414)

//START THE LISTENER
START LISTENER(LISTENER.PG3RT1)

Now i am trying to connect to the Queue Manager using following java client. connection is rejected with the following error.

    15:06:52.175 [localhost-startStop-1] ERROR c.b.c.s.s.m.MQUtil - MQJE001: Completion Code '2', Reason '2035'.

Can anyone advise why the connection is failing. Do i need to enable remote administration on the queue manager?

Following is the code fragement i used for connection

public void init(){
    MQEnvironment.hostname = hostName;
    MQEnvironment.port = Integer.valueOf(port);
    MQEnvironment.channel = serverChannelName;
    MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES);
    LOGGER.info("queueManagerName: " + queueManagerName);
    LOGGER.info("hostName: " + hostName);
    LOGGER.info("serverChannelName: " + serverChannelName);
    LOGGER.info("port: " + port);
    //initialize the connection pool
    MQPoolToken token = MQEnvironment.addConnectionPoolToken();
    try {
        mqQueueManager = new MQQueueManager(queueManagerName, MQEnvironment.properties);
        LOGGER.info("mqQueueManager: " + mqQueueManager);
    } catch (MQException e) {
        LOGGER.error(e.getMessage(), e);
    }
}

Answer 1

MQRC 2035 is MQRC_NOT_AUTHORIZED. The reason this was returned can be found in the AMQERR log on the queue manager.

As CHLAUTH hasn't been configured, and is on by default, I expect you're not able to connect as you're not passing the CHLAUTH rules.

Answer 2

It is quite likely that this is an authorization issue. The easiest is to look at the return code and interpret

mqrc 2035 returns MQRC_NOT_AUTHORIZED

One of the reasons for it could be permissions. This can be resolved either by setting the right privilges on the QueueManager (setmqaut) , then on the channel enable the user with you are connecting to MQ to authorize as explained here . Post this you can use the code to connect by adding userId to the MQEnvironment and go

You can also refer this technote for information.

Answer 3

We are using clearing the authentication setting on manager by runmqsc:

SET CHLAUTH('CNL_NAME') TYPE(BLOCKUSER) USERLIST(ALLOWANY)

ALTER QMGR CONNAUTH(' ')

REFRESH SECURITY TYPE(CONNAUTH)

in case of development. Or proper setting of credentials:

QueueConnectionFactory.createQueueConnection(props.get(PROP.USER), props.get(PROP.PASSWD));

for JMS or:

...
MQEnvironment.userID = uid;
MQEnvironment.password = passwd;
new MQQueueManager(isQueueMgr);

for native com.ibm.mq.MQQueueManager.
