Hi, I'm looking at the message length limits on OS/390. The manual says the limit is 63K for shared queues and 100MB for non-shared queues. I'm not clear on the "shared/non-shared" concepts.
Does "shared" means the queue shared by multiple queue managers in the same group of queue managers or it means the queue cannot be opened for put/get simultinuously by multiple transactions ?
Thanks

Thanks. It means the new limits for message length on the OS/390 is 100MB if we're not sharing queue managers ?

Hi..
It's right about the limits...
But if you're planing to use 100MB messages you will have to look on the CHIN task. There is a limit on the CHIN to obtain about 1,7 GB of storage and that gives about 16 channels active on max. msg. size. 
There is also some performace considerations on the MSTR task due to buffers, logs and page sets.
The introduction of message segmentation look to me as a better approch for huge messages, because of a better usage of system resources.
Thats my opinion ...
