Hi All,
We have a critical requirement where the GetAfter should fire on a specify Queue not for all, which is happening now for Put1After event and not for GetAfter  .
To be specific, we want the Queue Name which is (reading) getting the message from the respective Queue. 
Put1After:
void MQENTRY Put1After(PMQAXP pExitParms, PMQAXC pExitContext, PMQHCONN pHconn, PPMQOD ppObjDesc, PPMQMD ppMsgDesc, PPMQPMO ppPut1MsgOpts, PMQLONG pBufferLength, PPMQVOID ppBuffer, PMQLONG pCompCode, PMQLONG pReason)
GetAfter:
void MQENTRY GetAfter(PMQAXP pExitParms, PMQAXC pExitContext, PMQHCONN pHconn, PMQHOBJ pHobj, PPMQMD ppMsgDesc, PPMQGMO ppGetMsgOpts, PMQLONG pBufferLength, PPMQVOID ppBuffer, PPMQLONG ppDataLength, PMQLONG pCompCode, PMQLONG pReason)
As the above two prototype depicts a typical GetAfter Event and Put1After Event in API Exit.
As We have a parameter PPMQOD ppObjDesc in Put1After. But this is not available for GetAfter.
Can anybody suggest me regarding this issue.
regards,
Shalini. |

Hi,
This is not as simple as that. On the open, you will need to store the queue name and the object handle in say a link-list. Then in your GetAfter, you will search the link-list comparing the current object handle with one from the list. When you find a match then you will have the queue name.
Regards,

Thanks for your kind reply.
We have a few queries.
In your valuable suggestion what about the following:
a. Performance.
b. How many calls will be made to GetAfter.
c. What will happen to the function where call is for other Queues.
regards,
Shalini |

Hi clindsey,
Thanks for your reply
I had review on mirrorq.c, which in detail talks about all events except GetAfter.
I am very much keen to know about GetAfter.
Please suggest.
regards,
shalini. |

I recommended you look at the sample to see how you can use a list to map object handles to queue names. Accessing the list during GetAfter or PutAfter is the same concept. It should be pretty easy to plug in the code you need to make this work for GetAfter as well as PutAfter.
