According to the document Disabling CMMN and Standalone Tasks, I didn’t need the CMMN
and set the cmmnEnabled
to false. After running the Server, Cockpit first page could not get the data from Rest API and the Rest reported 500 Error.
The Rest API that reported 500 error is here:
http://localhost:8080/camunda/api/engine/engine/default/case-definition/count?latestVersion=true
And the response of above Rest:
type-> "ProcessEngineException"
message-> "An exception occurred in the persistence layer. Please check the server logs for a detailed message and the entire exception stack trace."
Notice that I use H2-create-drop
database. When the database and tables are created, CMMN
table will not be created. so the Rest API can not find the CMMN
table.
The dmnEnabled
property, behaves similarly to cmmnEnabled
.
