Hi,



There is one Legacy database DB1 and other Oracle Applications Database DB2. I created a Read-Only Materialized View in Legacy Database DB1 which fetches the data from Oracle Apps Database DB2 Tables.

Now my question is,

When there will be a downtime for oracle Applications Database DB2 then will new Materialized View be accessible in Legacy Database DB1?
Regards and Thanks in Advance!!
Jayaprakash.

Yes, it will be queryable, but it cannot be refreshed whilst the source database is down.

The materiliazed view will refresh every day in the morning, so the next day morning if data base is up then is it refresh?

"Refresh" involves collecting the data from your DB2.
So if database DB2 is not running, no data can be collected.
The refresh will fail, but there is still data in your materialized view on DB1, however the data will be out-of-date.

Can you access your pc's hard-drive when it is not running?
Can you accept phone-calls when your mobile is not switched on?

EDIT: seems you updated your question, now the answer is YES Smile
