Installing and configuring Workflow Manager 1.0 can be frustrating, if you do not follow the right steps. I installed Workflow Manager 1.0 and ran the default configuration successfully. After installation, I figured that I need to install following cumulative update in the order specified below.
After installation of above CUs, I was able to create a WF Manager based site workflow and publish it successfully and I thought I cracked it!
But when I tried to browse the site workflow, the page threw an error. The ULS log suggested that there was an error in Data Access Layer. So I fired up the SQL Server Profiler and figured out some database entries were missing in following table. See the screen below for the table and the error text:
Microsoft.Workflow.TestServiceHost.exe Error: 0 : System.IO.InvalidDataException: A required Workflow Configuration 'WorkflowServiceScopeSnapshotProcessBatchSize' is not present. Please add this configuration value.
I put the entry my self, don’t ask how I came up with values, I put random large numbers because I couldn’t wait to see my workflow working. I put about 4 entries in that table before and finally, the error changed to something else. To be precise, now the error was a missing parameter in a Stored Procedure and finally, I gave up thinking that there must be something terribly wrong here… I decided to uninstall it
