Question # 15

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 files 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 files 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.

1, 3, 4, 6, 8

B.

2, 3, 5, 7

C.

2, 5, 6, 7
