Hi all;
I'm using the CICS mQ brige facilities to call a cics program using DPL.
The message would be put into the Q1 which is a Bridge Q, The related program would be called and the result would be put into the ReplytoQ Q2 from which the requested client program would consum the message using MQGET call. The interesting phenomenoun is that the program would be executed (called bu the bridge) whenever the MQGet api times out. I mean it runs under a transaction since the syncpoint property of the MQPMO is not used. Any idea about this? |

Any idea about what? What about this is unexpected? Or unwanted?

If the MQGET with WAIT times out, the app will see the 2033 no-message-available, AND should know that whether or not there was a message the last time the MQGET was executed. If there was no previous message, the app itself can then call the routine you want executed?

| Despit of not specifying the MQPMO_SYNCPOINT option , it requires to specify MQPMO_NO_SYNCPOINT. When i add no_syncpoint option it has been coorected. |

Mainframe default is syncpoint, distributed platforms the default is no syncpoint.
This is basic essential knowledge for mainframe users. RTM. |
