After upgrading Cognos 8.3 to 10.1 i tried after upgrading the content store to create a delpoyment export. When i try this i receive this error…
CM-SYS-5227 A database constraint violation was detected. The current database transaction will be rolled back. Method-Name: “handleSQLExceptionForNewObject” Object-ID: “2591”. DPR-ERR-2082 An error has occurred. Please contact your administrator.
i fixed this to run a consistency check for all namespaces and with the option “find & fix”. I cleaned a dozen users and after that the export ran fine.
Hope this works for you as well!
