Hi,
We have a Solaris machine with lots of queue managers (about 19), lots of brokers (about 10) and system monitoring and Oracle installed. We're struggling with reliabilty and I suspect it is due to the system kernel and file descriptor settings in /etc/system.
Has anyone else got a really large configuration that would be willing to share details of what they have running and the etc/system settings that they're using that is keeping the system up?
Thanks,
Kulbir. |

I am suprised this thing runs at all if you are correctly representing your enviroment. 10 brokers?! How do you admin that beast? How much memory and how many MIPS do you have? (I think you are going to have issues on this system no matter what, you almost have to be over extended when you have everything running.)

We have a beast of a machine to go with the configuration 
We've got 1280 hardware with about 8CPU's and 8Gb RAM. We just haven't tuned it well! |

I think a better question than "how" is "why" - why on earth do you need so many brokers any qmgrs?? I have *never* encountered a true need for so many qm's, usually this is simply poor design (no offence).
Best way to achieve stability is to have less qms/brokers.... |

| If your machine is big enough why would you buy extra machines and pay IBM for a whole load more licence and also increase infrastructure and maintenance costs? |

Hi,
maybe its a memory problem, 8 GB is maybe to few.
Our 6 brokers, 12 qmgrs, DB2, sysmon, clustersoftw + some apps are using already 8GB auf our 12GB.
How many DataFlowEngines have you running and how much memory do they consume ?
How big is your used swap space ?
Greetings

Depending on the platform you pay by engine, so an 8 way box costs the same as 4 - 2 way boxes. I thought that was the way the licensing worked on solaris as well... (Though that doesn't matter if the hardware costs are not comparible) We have about 50 queue managers running on 3 engines in a linux virtualization.
