Authorization required for rollforward
You must have SYSADM, SYSCTRL, or SYSMAINT authority to use the rollforward utility.
Privileges enable users to create or access database resources. Authority levels provide a method of grouping privileges and higher-level database manager maintenance and utility operations. Together, these act to control access to the database manager and its database objects.
Users can access only those objects for which they have the appropriate authorization; that is, the required privilege or authority.
