Cognos 10.2.1.2 --> Event Management Service Partially Available Error

[ratna2cognos]

Hi,

I am working on Cognos 10.2.1 FixPack2 version and all components (Gateway, Content Manager, Dispatchers) are installed in a single server computer. Recently I have started getting the error says "DPR-ERR-2014 Unable to load balance the request because no nodes in the cluster are available, or no nodes are configured for the service: eventManagementService." when I click on Upcoming Activities ONLY. I have gone through the threads in this forum but not much useful to resolve my issue.

I have verified the below options:
       1) EventManagementService is set to TRUE in Cognos Configuration
       2) Able to see the schedules under Past Activities and Current Activities (Cognos Admin --> Status)
       3) When I click on Upcoming Activities ONLY I am getting the error DPR-ERR-2014 Unable to load balance the request
       4) Verified the status of EventManagementService in Cognos Admin --> Status --> Dispatcher --> EventManagementService. The status shows "Partially Available"

Can someone please suggest me how to resolve this issue.

Thanks in advance.

Ratna

If you also have this in your log...
"CNC-SDS-0322 Database update failed with error code INVALID_DATASTORE_VERSION. The JSM service will be aborted."
Then if you don't mind losing your schedules, then you could try this (deleting schedules is not sufficient, need to remove tables)
