4. Downtime on the primary database for any reason must be kept to a minimum.
Components referred to in the broker commands are:
Which Data Guard broker commands are needed to implement these requirements?
A. EDIT DATABASE prima SET PROPERY REDOROUTES=’ (LOCAL: physt1, FASTSYNC)’; EDIT DATABASE prima SET PROPERY REDOROUTES=’ (LOCAL: fs1 SYNC)’; EDIT FAR_SYNC fs1 SET PROPERTY REDORUOTES=’ (prima: physt2 SYNC)’; EDIT CONFIGURATION SET PROTECTION MODE AS MAXAVAILABILITY;
