I am using mq client with c#. I am connecting mq manager over the
network company a to company b. I would like to know even though there is no error on mq manager is there any possibility of message not
delivered to server. Are is it necessary to implement single phase
commit to make sure transaction is complete. |

Once you receive a good return code from MQPUT, then MQ has got the message (it should be marked as persistent).
Whether or not you put under syncpoint or not, doesn't really affect this but gives you more control over when to end the unit of work. If there is a failure of the application before the commit, the message will not be sent. If you don't want this to happen, don't use syncpoint.
It will then be safely delivered once and once only, infrastructure permitting. If you want confirmation of delivery or arrival, there are options to request COD or COA messages to be returned. |

With all the usual, oft-discussed pros & cons of such messages.
