Technically, different MViews in a schema would have been built for different purposes (user requirements). So, they are [expected] to be refreshed at different times / intervals.
If you need multiple MVs refreshed together, define a Refresh Group.

How can we improve materialized views based on complex queries such as join and union and make quicker refresh ?

Hi this helpful, but for some reason it asks me that I need to declare mview_name. Not sure if its because I am running this code in SQL developer and should run it from the command shell

Aah ! How many times do developers and DBAs use / configure an account with the DBA role when the DBA role isn't required !

TLDR, Refresh all mviews refreshes all mviews :)
