ORA-12039: unable to use local rollback segment "[string]"
Cause: A local rollback segment was specified in the CREATE MATERIALIZED VIEW command, but automatic refresh parameters were not specified. Therefore a refresh group was not created to automatically refresh the materialized view and the local rollback segment can''t be registered for future use.
Action: Either supply the automatic refresh parameters so that a refresh group will be created or do not specify a local rollback segment.
Error Type: ORA
