Working with a Second (Failover) WebView Database 
To allow users continued access to favorites and saved report definitions, you must install and maintain 
a copy of the WebView database. If the primary WebView database fails, you can redirect to the failover 
database without re-running ICM Setup.
Redirecting to the failover database is achieved by changing the ODBC DSN and can take about an hour. 
Reporting users can continue to work with WebView during that time but will not have access to 
favorites, shared reports, and scheduled report definitions until the switchover is complete.
If you choose to maintain a WebView database for use in a failover scenario, implement a regular backup 
schedule to ensure that it is current and contains the same favorites and shared reports as the primary 
WebView database.
