Step 6: Start the Cognos service on the first Content Manager Server—For distributed Cognos installations only
If your deployment includes a distributed Cognos Analytics installation, after you install the Cognos software on the first server, start the Cognos service on this server to designate it the active Content Manager.
Start the Cognos service on the rest of the Content Manager Servers only after you perform steps 1-5 on all the standby Content Manager Servers.
