QUESTION NO: 2
After creating a RAC One Node database using SQL statements, you want to register this database with Oracle Clusterware as a policy-managed resource.
Which command, or sequence of commands, should you use?
A. srvctl add srvpool -serverpool ron -importance 100 -min 2 -max 2 -servers 016n1, 016n2srvctl add db
-db ron -oraclehome $ORACLE_HOME -dbtype raconenode -serverpool ron
B. srvctl add db -db ron -oraclehome $ORACLE_HOME -dbtype raconenode -server 016n1, 016n2
C. srvctl add db -db ron -oraclehome $ORACLE_HOME -dbtype raconenode -serverpool ron -server
016n1, 016n2
D. srvctl add srvpool -serverpool ron -importance 100 -min 2 -max 2 -servers 016n1, 016n2srvctl add db
-db ron -oraclehome $ORACLE_HOME -dbtype raconenode -server 016n1, 016n2
Answer: C
Explanation
If your Oracle RAC One Node database did not register automatically with Oracle Clusterware, then use the srvctl add database command to add an Oracle RAC One Node database to your cluster.
For example:
srvctl add database -c RACONENODE [-e server_list] [-i instance_name] [-w timeout] When you add services to a policy-managed Oracle RAC One Node database, SRVCTL does not accept any placement information, but instead configures those services using the value of the SERVER_POOLS attribute.
Note: Use the srvctl add database command to add an Oracle RAC One Node database to your cluster. For example:
srvctl add database -c RACONENODE [-e server_list] [-i instance_name] [-w timeout]
* -c {RACONENODE | RAC | SINGLE}
The type of database you are adding: Oracle RAC One Node, Oracle RAC, or single instance.
QUESTION NO: 3
Examine these commands:
srvctl add service -db RACDB -service CRM -preferred RACDB_1 -available RACDB_2 - tafpolicy preconnect srvcl start service -db RACDB -service CRM Instances RACDB_1 and RACDB_2 run on host0l and host02, respectively.
This is the only TNS entry in the client side tnsnames.ora:
CRM =
(DESCRIPTION =(FAILOVER=ON) (LOAD_BALANCE=ON)
(ADDRESS= (PROTOCOL=TCP) (HOST=host0l-VIP.example.com)(PORT=1521))
(ADDRESS= (PROTOCOL=TCP) (HOST=host02-VIP.example.com)(PORT=1521))
(CONNECT_DATA = (SERVICE_NAME = CRM)
(FAILOVER_MODE = (BACKUP=CRM_PRECONNECT)
(TYPE=SESSION)(METHOD=PRECONNECT))))
Which statement is true regarding the TAF settings?
A. Clients using this configuration fail over and restart any active queries automatically.
B. Clients using this configuration fail over and restart any active transactions automatically.
C. This configuration will work only for a policy-managed RAC database.
D. The configuration is incomplete because the TNS entry for the preconnected backup session is missing.
