Workflow Manager service in Error state after Dec14 CU install

Question

After installing Dec 14 CU and updating the WF farm to CU2 I tried to run the cmdlets as per here -
https://technet.microsoft.com/en-us/library/dn133867.aspx?f=255&MSPPError=-2147217396
$credential = [System.Net.CredentialCache]::DefaultNetworkCredentials
$site = Get-SPSite https://teams.sharepoint.com
$proxy = Get-SPWorkflowServiceApplicationProxy
$svcAddress = $proxy.GetWorkflowServiceAddress($site)
Copy-SPActivitiesToWorkflowService -WorkflowServiceAddress $svcAddress -Credential $credential -Force $true
This errors:
Copy-SPActivitiesToWorkflowService : An internal error occured. For more details, please see the server logs. Client
ActivityId : cb2a40af-2c50-4e5c-8ac2-c5436c351b89.
At line:1 char:1

   -SPActivitiesToWorkflowService], InternalServerException
    + FullyQualifiedErrorId : Microsoft.SharePoint.WorkflowServices.PowerShell.CopySPActivitiesToWorkflowService
I then ran get-WFFarmstatus on the WF server (3 in the farm) and see that the service is stopped on all the WF servers with a warning:
WFserver1      WorkflowServiceBackend                                                 
Stopped
WARNING: Endpoint https://WFserver1:12290/ is not responding: The remote server returned anerror: (500) Internal Server Error.
WFserver1      WorkflowServiceFrontEnd                                                
Stopped
Checked the underlying services and IIS on the 3 WF servers and these are all now started but the WF service cannot be started:
net start WorkflowServiceBackend
The Workflow Manager Backend service is starting.
The Workflow Manager Backend service could not be started.
A system error has occurred.
System error 1067 has occurred.
The process terminated unexpectedly.
The WF operational logs show this:
Unhandled exception in AppDomain:
Microsoft.Workflow.Common.FatalException: An unrecoverable error occurred. For
diagnostic purposes, this English message is associated with the failure: 'A
required Workflow Manager configuration
'WorkflowServiceScopeSnapshotProcessBatchSize' is not present. Please add this
configuration value.'. ---> System.IO.InvalidDataException: A required
Workflow Manager configuration 'WorkflowServiceScopeSnapshotProcessBatchSize'
is not present. Please add this configuration value. <o:p></o:p>

Microsoft.Workflow.Common.AsyncResult.End[TAsyncResult](IAsyncResult result) <o:p></o:p>
at
Microsoft.Workflow.Service.WorkflowServiceBackendHost.OnStartCompleted(IAsyncResult
result) <o:p></o:p>
There is a suggested fix for this here -

I’d like to at least get some feedback as to whether this is safe/supported (MS doesn’t like
any tinkering with the DBs…) – or whether we should go down the uninstall/reinstall
the Workflow farm route  - thanks

Hi,
For your issue, try to provid EXECUTE permission for role "WFServiceOperators".
Add Workflow service account as “WFServiceOperators” into the database. Here are the steps to apply permissions:
Open the Query Window and Select the database “WFInstanceManagementDB”
Write the following line of script:
GRANT EXECUTE TO WFServiceoperators
Hit Execute.
Repeat the steps for database “WFResourceManagementDB”
