Exiting: MQCONNX: MQCC = MQCC_FAILED [2] MQRC = MQRC_RESOURCE_PROBLEM [2102]

Hi Mark,

I have update my GO Beat Code to a new version of "github.com/ibm-messaging/mq-golang/ibmmq". Afterwards I get the error code Exiting: MQCONNX: MQCC = MQCC_FAILED [2] MQRC = MQRC_RESOURCE_PROBLEM [2102]. Your example works.

/ Prepare mq client / func connectMqQueue(bt *Mqbeat) error { debugf("msb-beat -> connectMqQueue -> entry.")

var err error
var mqreturn *ibmmq.MQReturn

cno := ibmmq.NewMQCNO()

logp.Info("msb-beat -> connectMqQueue -> set mq connection channel %s.", bt.config.ChannelName)
cd.ChannelName = bt.config.ChannelName

logp.Info("msb-beat -> connectMqQueue -> set mq host(port) %s.", bt.config.ConnectionName)

// and indicate that we want to use the client
// connection method.

    csp.UserId = bt.config.UserId

    logp.Info("msb-beat -> connectMqQueue -> set mq client user password.")

    // And make the CNO refer to the CSP structure
    cno.SecurityParms = csp

    cno.Options = ibmmq.MQCNO_SHARED_BINDING
}

cno.Options |= ibmmq.MQCNO_HANDLE_SHARE_BLOCK

// And connect. Wait a short time before
// disconnecting.
bt.qMgr, err = ibmmq.Connx(bt.config.QmgrName, cno)

For that RC I'd normally expect there to be an FDC file created or something in one of the AMQERRxx.LOG files that gives more information.

Hi Mark,

here the solution. If anyone wants to mq golang with libbeat 7.x he has to disable seccomp in the beat configuration.

https://www.elastic.co/guide/en/beats/filebeat/master/linux-seccomp.html

seccomp.enabled: false

[ibmmqmet]

Well found. I wouldn't have thought of that. Might be interesting to see which specific system calls could be added to the default policy rather than a blanket disablement, but that's always likely to be empirical - rarely-taken paths in the code might expose additional system calls.
