Title: Cognos multi Gateway and Dispatchers configuaration
Post by: joseph123 on 08 Apr 2013 07:02:25 PM
Hi


Please clarify  the following with respect to my org environemnt.

Machine1: Gateway1 and Webserver1
Machine2: Gateway2 and Webserver2
Machine3: Dispatcher1, ContentManager1
Machine4: Dispatcher2, ContentManager2


Q1) How should I configure Gateways so that users can enter http://orgname/c10 to enter to cognos portal.

Q2) How internal loadbalancing will be implemented for these Gateways.

Q3) How Dispatchers will be configured and integrated for failover purpose.

Your help will be highly appreciated.

Thanks,
Joseph

With an external appliance (load balancer), and a DNS entry.  Cognos does neither of these natively

Load balancing is native to dispatchers.  Just add all dispatchers to the configuration for each Cognos gateway

If you are going to do fail-over for Content Manager, it's a good idea to put Content Manager on dedicated boxes.  Long story short, sharing CM on a report server can cause instability and environment crashes when system is under load (load being badly written reports/badly modeled FM packages, not just traffic).  Long-running tasks can cause the secondary CM to lose the heartbeat and take over the environment, then clashing with primary when it comes back -- I've seen it happen multiple times.
