This question keeps coming everytime.
What is the best (in terms of performance) way to aggregate messages in wmqi? (Does MB have anything better?)
I can think of
1.The good old data base solution (bad on performance)
2. Aggregator family nodes (again a db used internally , locking and db issues)
3.Match using a common id , limitations are that not all messages are available at the same time and wmqi cannot wait , applications cannot change etc.
Any suggestions , specially those that are running successfully with good performance till date??? |

I have used the MQGET node to aggregate replies. It was implemented in wmqi (V2) and has been in production for more than a year. We can not use the aggregation node because we do not know how many replies we are going to get. The application sends a message to MVS to trigger a CICS transaction. Dpending on the content of the message, the CICS transaction will call other CICS transactions producing a number of reply messages. At the completion of these CICS transactions, a control message is returned telling us how many replies we should expect. This control message kick off a message flow. We loop the MQGET node against the reply queue until we get all the replies or timed out. It is fast, no DB involved.
I was at the MQ conference, they said that the MQGET node will be fully supported in CSD04 of V5. |
