Oracle Exam 1Z0-076 Topic 5 Question 18 Discussion

Actual exam question for Oracle's 1Z0-076 exam
Question #: 18
Topic #: 5
[All 1Z0-076 Questions]

Examine the Data Guard configuration:

DGMGRL> show configuration;

Configuration - Animals

Protection Mode: Max Availability

Databases:

dogs - Primary database sheep

- Physical standby database cats

- Physical standby database

Fast-Start Failover: DISABLED

Configuration Status: SUCCESS

An attempt to enable fast-start failover raises an error:

DGMGRL> enable fast_start failover;

Error: ORA-16693: requirements not met for enabling fast-start failover

Failed.

Identify three possible reasons for this error.

Show Suggested Answer Hide Answer
Suggested Answer: C, D

To increase the number of applier processes on a logical standby database, the following changes can be made:

C: Increasing the value for the MAX_SERVERS SQL apply parameter would allow for more applier processes to be initiated, assuming that system resources permit.

D: Increasing the PARALLEL_MAX_SERVERS initialization parameter would allow for more parallel execution processes, which can be used by SQL apply to increase the number of applier processes.

Option A is incorrect as decreasing the number of archiver processes will not necessarily increase the number of applier processes; these are unrelated components.

Option B is incorrect because the 'FREPARER' processes do not exist, it seems to be a typographical error, and the 'REPARER' is not a valid Oracle process or parameter.

Option E is incorrect because the RECOVERY_PARALLELISM parameter controls the number of processes used for instance recovery and media recovery, not for SQL apply.

I bet the problem is with the async LogXptMode on one of the databases. Gotta keep those logs in sync for fast-start failover to work.

Dogs and cats, huh? Sounds like a classic Data Guard setup. I wonder if the animals are getting along in that configuration.

I think option C could also be a reason for the error, as the LogXptMode property is set to FASTSYNC on Cats while Sheep is the target standby database.

Ooh, this is a tricky one. I'm guessing the fastStartFailoverTarget property is the culprit here. Gotta make sure that's set up properly.

I agree with Augustine. Option A seems like a possible reason for the error.

Hmm, let's see. I think the error could be related to the LogXptMode property on the standby databases. Maybe it's not set correctly for fast-start failover.

A) The fastStartFailoverTarget property is not set on Dogs.

I think the error might be due to option A, the fastStartFailoverTarget property not being set on Dogs.
