• B.Database clients must disconnect before the online relocation timeout expires.
• C.The database must be stored on shared storage.
• D.Database clients must use Transaction Guard to prevent them from losing their connection.

Oracle Clusterware manages an administrator-managed database service defined with the MANUAL management policy.
Which two statements are true?

• A.The service must be manually restarted with SRVCTL every time the instance hosting the service fails.
• B.Clusterware will monitor the service while it is active.
• C.The service must be manually restarted with SRVCTL after restarting the Clusterware stack on the node hosting the service.
• D.The service must be manually started with SRVCTL after a planned restart of the instance hosting the service.
• E.When manually started, the service will always start on one or more available instances rather than on their preferred instances.

Examine the output of the asmcmd and srvct1 commands:

You execute this command:
$ srvctl modify asm -count 2
All databases on the cluster are running from Oracle 12c homes.
Which statement is true about the outcome of this command?

• A.The command fails because the instance count cannot be reduced to less than the minimum value of 3.
• B.ASM instances continue running on all three nodes until all database instances connected to one of the ASM instances shut down.
• C.One ASM instance is shut down and the instance count is reduced by one.
• D.The command fails because one ASM instance must be shut down manually before executing the command.

You plan to use DBCA to convert a single-instance Oracle 12c database on a local filesystem on a stand-alone server to RAC by using ASM.
You installed Grid Infrastructure 12c on a four-node cluster.
Examine this list of possible conversion steps:
1. Create a template and image les from the single-instance database by using DBCA.
2. Perform an RMAN backup of the single-instance database.
3. Validate the cluster using CLUVFY.
4. Copy the template and image les to a cluster node.
5. Restore the RMAN backup to the recovery area disk group on the cluster.
6. Perform an Oracle Database 12c RAC installation.
7. Create a RAC database with DBCA using the RMAN backup.
8. Create a RAC database with DBCA using the template.
Which statement correctly lists the minimum steps required to perform the conversion?

• A.2, 5, 6, 7
• B.1, 4, 6, 8
• C.2, 3, 5, 7
• D.1, 3, 4, 6, 8
• E.2, 5, 7
• F.1, 4, 8

Which three statements are true concerning policy-based cluster management in Oracle 12c Clusterware?

• A.Server pools must be managed with the srvctl utility for servers hosting a database.
• B.The server pool contains servers that host administrator-defined high availability resources.
• C.All servers in a new cluster installation belong to the generic server pool.
• D.All servers in a new cluster installation belong to the free server pool.
• E.Server Pools must be managed with the crsctl utility for servers hosting an application or other administrator-defined high-availability resource.
