I have came through the issue that has been encountered while working with an Oracle SOA composite running in the Oracle IDAM environment.
When restarting server stack containing (OAM, OIM, SOA), customized DefaultOperationalApproval crashed (with UNKNOWN status) if anyone has gone through the same please help me out.
I have tried with deleting unused composite (DefaultOperationalApproval 5.6)that prompts the error on the log(under WFTASKMETADATA table).
SOA diagnostic log-:
Failed to retrieve task metadata information for taskDefinitionId: default/DefaultOperationalApproval!5.6/ChallengeTask in listTaskMetadataByNamespace(). Will continue with other task meta data in the result.
