Topic #: 1
[All 1z0-066 Questions]

Examine the Data Guard configuration:
DGMGRL > show configuration;

Configuration-Animals -
Protection Mode: MaxAvailability
Databases:
dogs- Primary database
dogsfsl Far Sync
sheep- Physical standby database

Fast-Start Failover: DISABLED -
Configuration Status:

SUCCESS -
An attempt to enable fast-start failover raises an eror:
DGMGRL> enable fast_start failover;
Error: ORA-16693: requirements not met for enabling fast-start failover
Failed.
Identify two possible reasons for this error.

  • A. The FastStartFailoverTarget property is not set on Sheep.
  • B. The FastStartFailoverTarget property is not set on Dogs.
  • C. The FastStartFailoverTarget property is not set on DogsFS1.
  • D. The LogXptMode property is set to ASYNC on Dogs.
  • E. The RedoRoutes property is not set on Dogs.
  • F. The RedoRoutes property is not set on DogsFS1.

Suggested Answer: AD 🗳️
D: Ensure that the LogXptMode property for both the primary database and the Fast-Start Failover target standby database are SYNC.
A: If more than one physical or logical standby database exists, in this case it is the sheep database, you must specify the FastStartFailoverTarget value explicitly, prior to enabling fast-start failover. The indicated target is verified when fast-start failover is enabled.
Note: DGMGRL> enable fast_start failover;
Error: ORA-16651: requirements not met for enabling fast-start failover
Failed.

SOLUTION -
1) Check whether the flashback database is enabled on primary & standby database
Select flashback_on from gv$database;
2) Check whether you have set the FastStartFailoverTarget parameter.

Answer: D and E ORA-16693 - requirements not met for enabling fast-start failover Cause The attempt to enable fast-start failover could not be completed because one or more requirements were not met: The effective redo transport mode for both the primary database and the fast-start failover target standby database must be set to either SYNC or FASTSYNC if the configuration protection mode was set to MaxAvailability mode.

To enable fast-start failover when a far sync instance is used to ship redo data to the standby database, the FastStartFailoverTarget property must first be set on both the primary and target standby database

I think B and F B - because the FastStartFailover target must be enable on the primary (dog) F - if you use FarSync (DogsFS1) to send redo to the target standby you must define RedoRoutes
