Purpose
Troubleshooting Steps
 Situation A. This is the first time trying to fast refresh the materialized view
 Situation B. The materialized view used to fast refresh without issue
 Zero in on the underlying issue and cause
 Is this the first time the materialized view (mview) has been fast refreshed?
 Does the fast refresh work when you run it from sqlplus?
 Is there an error in the alert log or on your screen when the fast refresh fails?
 Did the problem start after you upgraded or applied a patchset (or PSU) to either the master or mview database (neither master nor mview databases are new)?
 Did the problem start after you moved either the master or mview database to a new database?
 Do you see no errors, yet the fast refresh never finishes?
 Is your issue still unanswered?
