Hi,

I am having an application that does a SYNCPOINT get. The requriement is, from the Queue only those messages with a mathcing messages must be fetched and processed. And this get must be done under SYNCPOINT. So in my Java application I set the options like this:

getMessageOptions.options = MQC.MQGMO_NO_WAIT | MQC.MQGMO_SYNCPOINT | MQC.MQGMO_FAIL_IF_QUIESCING;
getMessageOptions.matchOptions = MQC.MQMO_MATCH_MSG_ID;
messageReceived.messageId = msgId.getBytes();

where msgId = some string;

int openOption = MQC.MQOO_BIND_ON_OPEN | MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_INQUIRE;

m_QManager.begin();
MQQueue queue = m_QManager.accessQueue("QName",openOption);
queue.get(messageReceived, getMessageOptions);
if( no_Error )
m_QManager.commit();
else
m_QManager.backout();

But this is failing with an MQ reason code 2121 which says No External Participant. Please let me know if any of the settings are missing.

Thanks and advance
