Hello experts,

I'm trying to understand how the SHARECNV works. Can we use amqsputc sample program to test this?

I tried and for every amqsputc a new instance of channel is being created. If amqsputc doesn't work for this, is there any other sample program that I can use?

Thanks

SHARECNV settings address apps that multi-thread, such that threads of the same app instance share a TCP channel. Amqsputc dos not multi-thread.

Search google for SHARECNV, and watch some of the slide shows that explain conversation sharing.

What are you actually trying to achieve through the use of sharecnv?

Sharecnv is essentially a mechanism for potentially reducing the number of sockets in use when multiple connections are made to the same queue manager from the same client application process. While a sharecnv value of more than 1 can reduce the number of sockets in such a scenario it often has other negative performance implications in both the client and the server.
It's unusual these days for there to be a shortage of sockets and sharecnv(1) tends to be the starting point for an MQ performance tuning exercise.

Have you made yourself familiar with the general advice in the MQ performance reports ?
