Troubleshooting
Problem
In IBM® InfoSphere® Master Data Management 11.6.0.11 and 12.0 deployments, the value of the value.serializer property in the KafkaResourceEnvironmentProvider component must be set to com.ibm.mdm.common.kafka.RuntimeValueJacksonSerializer. However, when you upgrade your InfoSphere® MDM deployment using the Upgrade_MasterDataManagement madconfig target, this value is not automatically updated.
Symptom
When this issue occurs, the following exception is shown in the SystemOut.log file:
000001a9 DWLExceptionU E com.dwl.unifi.tx.exception.ITxRxException: [Exception_NotificationManager_ClassInit:] CDKCN2002E:Exception occurred when initializing the following class.
