| Does anyone know why I can't use the MQGMO_NO_SYNCPOINT option with the MQMO_MATCH_CORREL_ID option? From a Windows application I need to keep up with the correlationIDs of the put and get messages, but I need to do a destructive get and remove the get message from the static queue when successful. I am using the MQMO_MATCH_CORREL_ID option to insure my correlated gets, and the MQGMO_NO_SYNCPOINT option to do destructive gets and removal from the ReplyQueue. When my application runs, the get fails with a 2046 : MQRC_OPTIONS_ERROR. Is there any reason that I don't know of, that will keep me from using these two options together? Any help will be greatly appreciated. |

UOW has nothing to do with the conditions you specify on a get, like in your case MQMO_MATCH_CORREL_ID. Post your complete GMO options and MD values here.
Also you could review "App programming reference" for any conflicts of this nature.

Here are my options:
theGMO.Options := MQGMO_WAIT +
MQGMO_CONVERT +
MQGMO_NO_SYNCPOINT +
MQMO_MATCH_CORREL_ID;
And my Descriptor:
getMQMD.MessageType := MQMT_REPLY;
getMQMD.Persistence := MQPER_NOT_PERSISTENT;
getMQMD.Format := 'MQSTR';
getMQMD.CorrelationId := putMQMD.MessageId;
My application runs fine with MQGMO_NO_SYNCPOINT specified and without MQMO_MATCH_CORREL_ID. Or vice-versa. |

Oops.. you got it at the wrong place. Should have been something like this.
theGMO.MatchOptions := MQMO_MATCH_CORREL_ID;
It is match options and has its own attribute in the GMO structure. It is NOT in the Options attribute.

| That was the fix. Thanks for the help. At first I didn't think I had that method, but I realized that the 200 Interfaces do not have some of the methods and properties that the 500 Interfaces have. I have switched to the 500 Interfaces and everything is working fine. Thanks again. |
