Title: number of dispatchers allowed for one gateway
Post by: Chopin on 26 May 2015 06:22:02 AM
Hi Guru's,

Does anyone has experience regarding the number of dispatchers allowed for one gateway ? I met a issue that it ok when 4 dispatchers serve one gateway , when the number added to 6, the newly added 2 dispatchers become 'unavailable '. I don't know if it's because there are some restriction on number of dispatchers allowed for one gateway.

Thanks a lot in advance for your help !

I dont think there is any such limit for only 6 dispacthers. Its very common scenario and anyways your gateway will be communicating to only first dispacther URL configured.

Its something else happening with your dispacther. Check the log file more details. Check if those dispacthers are registered properly under the active content manager.

Hello Chopin,
I agree with sunosoft, I am unaware of any limits on the number of dispatchers that you can specify on your gateway configuration. The gateway basically runs down the list of the dispatchers to find the first available dispatcher. If it always finds the first dispatcher up and running, it will always forward to that dispatcher.

From your problem description it appears that you only added the 2 new dispatchers and that the other 4 were pre-existing. If that is the case, I would also check the Dispatcher password property of all the pre-existing ones within their respective cognos configurations. That password should be the same across the board. By default it is set as 'NoPasswordSet'.

Thanks, sunosoft, cognos810.

I have considered about  Dispatcher password property , they are the same(default password).
The issue is regarding Firewall. After turn off firewall as configured  the  same in dispatcher1 to dispatcher 3.
These 6 dispatchers works normally .

Thanks once again.
