Configuring "weight" in services

b.petronio — Thu, 21 Feb 2008 14:58:25 GMT

Hello all,

I'm a little confuse, because i think i have a fine configuration, in the content rule as well as in the service's, regardless the weight parameter.

What i want is to double load service esl0011-7778, because it is a better server, with a better performance.

Here are the config, and some show command's.

Best Regards,

Bruno PetrÃ³nio

Well,

After reading this:

"If you do not have a weighted roundrobin load-balancing method specified

for the content rule or do not have DFP specified for server load-balancing,

use the weight command only in service mode..."

I try to configure weight only on service's, and the behavior was the same.

Any ideas ?

Hi Bruno, I tried the weight on the service too, no change in amount of connections. We're running default round robin.

Tried this also, but would have to do after hours:

VCC-CSSa(config-owner-content[cls])# balance weightedrr

%% Operation may not be performed on active content rule

Question. Is 1 going to get the lower load or 10 as the weight. The CSM is 10 gets the higher load. Not sure on the CSS? Thanks

Bruno, not sure if this would work in your environment, but it served as a great workaround for me...

under service: max connections # you can set to what you want on the server and it doesn't go above. Found this in another thread.

Tks for your inputs Sheila,

As long as i understood the "CSS Load Balance Configuration Guide", if we have a service with weight 10, it will receive 10 times more connections, comparing with one with weight 1.

Now, i cant do the suggestion u make about balance mode weighteddr method, but i'll try as soon as possible, and will feedback.

Relating the "max connection #" command, i don't know what will be the threshold connections for 1 OAS, and then is difficult to adjust this parameter.

Thank you once again.

Changing the balance method from round-robin to weightedrr resolve this issue.

Nevertheless, i read somewhere that it should be running with roundrobin too.

Am i wrong ?
