In a distributed environment, when starting one of the Application Tier servers a “DPR-DPR-1035 Dispatcher detected an error” message appears in the details of the service starting in Cognos Configuration although the service does start successfully and appears to be working, i.e., reports execute successfully on it and there are no errors returned to end users, This server appears as “Unavailable” in Cognos Administration (under Status -> System) even though it is fully operational including executing new report requests
A “DPR-DPR-1035 Dispatcher detected an error” message appears in the details of the service starting in Cognos Configuration when starting up the App Tier only install. The dispatcher status is ‘Unavailable’ in Cognos Administration, but everything else appears to work correctly.
The affected dispatcher has a different Dispatcher password set in its Cognos Configuration, than that set for the active Content Manager.
Open up Cognos Configuration and select Environment.
On the Dispatcher password setting, make sure that all the dispatchers in the environment have set the same password.
The default dispatcher password is not blank! If you do not know the password, change on all servers the password and restart the servers again.
