Oracle Error Message
ORA-12039: unable to use local rollback segment “string”
Reason for the Error
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.
Solution
Either supply the automatic refresh parameters so that a refresh group will be created or do not specify a local rollback segment.
