Information in this document applies to any platform.
You are creating a local (no dblinks) read-only materialized view and it does not finish and gives you the impression it has hanged or creation takes much longer than expected.
Additionally if you issue a "Create Table As Select" command using the same Create Materialized view SQL definition, the CTAS finishes in a short time.
