Hi,
We have a web service that uses the functionality of the IBM Cognos SDK for the execution of reports from a web portal.

We would be needing to be able to balance the workload between 2 Dispatchers.

Is there any way to balance the load of SDK calls?

We have tested with Cognos internal load balancing but we could see that all executions are done by a single dispatcher, the one configured in the web service (in the connect method)
Example:
dispatcherURL = "http: // localhost: 9300 / p2pd / servlet / dispatch"

We are using Cognos 10.2.2

Thanks.

Do you have a gateway configured?  In our environment we typically make the dispatcher url = Gateway server.  Then the gateway server processes it as a normal report request which then uses all your configured routing rules, load balancing, and dispatcher settings.  If you are hardcoding dispatcherUrl = one dispatcher that server will be the only one processing the requests.

Hi Chirs,
Thanks for your answer.

My installation is distributed:
BICMDESA Server: Content Manager + Gateway (installed in separate folders)
BIAPP1DESA Server: Dispatcher
BIAPP2DESA Server: Dispatcher

Both Dispatchers are declared in Dispatcher URIs for the gateway

Gateway URL: "http: // bicmdesa: 80 / ibmcognos / cgi-bin / cognosisapi.dll"

I should replace the value:
dispatcherURL = "http: // biapp1desa: 9300 / p2pd / servlet / dispatch"

for:
dispatcherURL = "http: // bicmdesa: 80 / ibmcognos / cgi-bin / cognosisapi.dll"

Once this change is made, the load balancing rules will be applied and will begin to distribute the load between both dispatchers?

Note:
My environment is configured as Weighted Round Robin with a Processing capacity 1,1 because both dispatchers has the same configuration of hardware (Processor, Ram, HDD)


Regards

not 100% sure as we use cgi, but believe that looks correct.  This is what our endpoint URL looks like, which appears to be basically be the same as yours.

gatewayUrl="http://[servername]:[port]/ibmcognos/cgi-bin/cognos.cgi
