Well into the execution phase of an upgrade of NW Java 7.02 to NW Java 7.3, we encounter this nebulous error that is leaving me little in the way of "known issues" in my searches. Anyone encounter this or have ideas on why it's stopping now? An error has occurred during the execution of the Remove old db content step with action execute. Service com.sap.sdt.j2ee.services.servicesimpl.UndeployDBContentService failed with the following message: java.lang.NoClassDefFoundError: com/sap/dictionary/database/dbs/DbMsgHandler : cannot initialize class because prior initialization attempt failed You can find more information in the files /usr/sap/EP3/SUM/sdt/log/SWITCH/REMOVE-OLD-DB-CONTENT_06.LOG and ProcessOverview.html. Use the information provided to trouble-shoot the problem. There might be an OSS note providing a solution to this problem. Search for OSS notes with the following search terms: SWITCH,execute,offline-migration,remove-old-db-content,com.sap.sdt.j2ee.services.servicesimpl.UndeployDBContentService,class java.lang.NoClassDefFoundError The last log in the REMOVE-OLD-DB-CONTENT.LOG file reads: Sep 2, 2015 2:43:33 PM [Info ]: Check sap.com/ETPRJSCHEDULER SCAs for SDAs with DB content.
