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.
