Hi All,
I have a materialized view with refresh rate like this
CREATE MATERIALIZED VIEW MV_TEST
REFRESH FORCE
START WITH SYSDATE
NEXT SYSDATE + 1/24
AS
SELECT * fROM View_TEST


1)Does this mean that the materialized view would be refreshed every hour?

2)If it refreshes every hour what would be starting point time?

3)What if the database is unavailable/down at the time of next refresh time? Does it refresh immediately after the database becomes available?

Pls help me in understanding these. I am quite new to the concept of materialized view.

Thanks in advance.
Anand

1. Yes - SYSDATE + 1/24 = every hour

2. SYSDATE - the time you run the command.

3. Yes
