Hi,
found a hint to ms07 qtune
| Quote: |
The other utility is qtune and its purpose is to expose the queue buffer settings so that you can inquire on them and set them. In high-volume situations where the queue manager must be tuned for optimum performance, it is very common for the queue buffers to have been changed from the default settings

has anyone any tips, how to tune my system with this options?
What is npBuf? no persistent message buffer ? 
is ist better to set maximum? are there a few drawbacks to concern about?
had i to tune on q to q basis?
if I use only non persistent message on a specific q, should i set npBuf to max and pBuf to low number?
I didn't found any information, not in manuals, not with google 
any hint/tip is welcome 
bye Frank |

I'd guess non-persistent message buffer. Which implies non-persistent messages only.

Frank,
if you search for the words nonpersistent or persistent and buffer you'll find some hits.
basically it's a value you can set in bytes to increase the default memory buffer value before messages are written to disk in queue files (not logging as that only applies to persistent messages)
if you set the value it applies only to new queues created with the new value.
hope this helps a little...

a) it's in MS0P, not MS07
b) read the README that is part of the tool |

It's only like to be of concern for very high volume and time-critical, non-persistent applications, which are being constrained by MQ disk i/o.
Other approaches still apply - including optimising the application (number of instances for example). |
