Refer to physical_attributes_clause for more information on the PCTFREE parameter. Subsequent queries will not use the zone map and the database will no longer maintain the zone map. While zone maps are internally implemented as a type of materialized view, materialized view logs on base tables are not needed to perform a fast refresh of a zone map. PCT refresh is also not enabled on the materialized view Action: Use just REFRESH, which will reinstantiate the entire table. Looking for official info on using *.domain.com and how short domain names cause issues like *.abc.co I have run in to the issue with the *.abc.co and can resolve it (user provided a better URL so we can use *.sub.sbc.co) but need docs to go with my change control.

When you query the table (table with large number of columns) Materialized Views avoid scanning unreferenced columns from the base tables. You should explicitly grant privileges on the materialized view to the roles that should use that view. You can specify LEFT [OUTER] JOIN syntax in the FROM clause, or apply the outer join operator (+) to dimension table columns in the join condition in the WHERE clause. This clause lets you explicitly rebuild the zone map. You must specify a GROUP BY clause with the same SYS_OP_ZONE_ID function expression that you specified for the first column of the SELECT list.
