You had a meeting of the DBA team to discuss high availability and the possible uses of clustered
technology. There are two points of view that have emerged.
One suggests RAC license and a full RAC implementation including clustered ASM and RAC databases.
The other involves using the Oracle 10g R2 Clusterware and clustered ASM and protecting single-instance Oracle databases with no RAC for the databases.
You feel that RAC databases are a better solution. How would you make a case for RAC in the next meeting? (Choose three.)
A.
Non-RAC database instances do not provide for continuous availability of services.
B.
Clusterware can protect a non-RAC database but does not help protect the listener.
C.
RAC databases may use transparent application failover (TAF) to provide for continuous availability of services.
D.
RAC databases provide for a greater number of parallel execution slave processes and, therefore, provide for increased speedup of batch processing in all cases.
E.
RAC databases provide for a greater number of parallel execution slave processes, and therefore could provide for increased speedup and scaleup of DSS workloads.
F.
Protection of single-instance Oracle databases using ASM causes delays due to disk group mounts in the ASM instance on the node where the database instance is restarted by the Clusterware.
