Dispatcher to Dispatcher forward

[kris123]

Hello,

Code Select Expand

A dispatcher can also route requests to a specific dispatcher to run a given request .
taken from Architecture and Deployment Guide 10.1.1


How to configure dispatcher to dispatcher? and why is this kind of setup required?

please help

You must have a multi-server environment in order to do this... You can then have e.g. a server that is dedicated to handling Report Service request...

[kris123]

what will the dispatcher 1 do if a report service request comes? will it know that the request should be forwarded to dispatcher 3 for any report service requests?

please can you tell how it will be configured and where?

Sorry kris123, but just to be curious... Are all your questions related to your Admin certification?

It depends. If you have multiple report servers, the request could in theory be load balanced to any one of them. In practice, the gateway request is passed to a "driving dispatcher". If this has associated report services, the request will likely end up on one of these. Once more than 50% of the low affinity connections of that dispatecher are in use, it will then begin to load balance further incoming requests to the other dispatchers with report services in the architecture using a weighted round robin approach.

If you have specified routing rules for the package/user associated with the request, load balancing is ignored, and the request is passed directly to the dispatcher(s) included in the routing rule. 

If there are no report services associated with the "driving dispatcher" and only one other dispatcher in the architecture has them, then all report requests will get routed to the one dispatcher with reporting capabilities (via the driving dispatcher).

I think that about covers it :)
