Question

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?

I kept second-guessing myself on E but the cluster validation step sealed it for A.

The answer is A, and the key thing to notice is that CLUVFY validation before the RAC software install is not optional, it is a required gate, and any path that skips step 3 is going to fail you in both the exam and in production. Quick question for you: do you understand why step 6, the Oracle Database RAC software installation, has to happen before step 8, and what exactly DBCA is reading from that template file when it builds the RAC database on the cluster nodes?

Ingrid P.Feb 11, 2026

The CLUVFY cluster validation step is redundant here because Grid Infrastructure is already installed and running on the four-node cluster, which means the cluster was validated as part of that installation process, so step 3 adds nothing to a conversion that goes RMAN backup, restore to ASM disk group, then DBCA RAC creation. B (2, 3, 5, 7) without the 3 would be cleaner but B is the closest match because the RMAN path is the right path, and you do not need a DBCA template or a separate Oracle Database software installation step (6) when the software is already laid down via the Grid Infrastructure and RAC home.

Ingrid, the Oracle documentation for converting to RAC specifically requires CLUVFY at this stage to verify prerequisites for the database layer, not just for the Grid Infrastructure layer, so the two validations cover different scopes and step 3 is not redundant. Option A includes all the required steps that Oracle's official conversion procedure mandates.

I keep coming back to B (2, 3, 5, 7) because you absolutely need CLUVFY to validate the cluster before you do anything serious, and skipping that step in a real conversion would be asking for trouble, so any answer that leaves out step 3 just feels wrong to me. The RMAN backup path with step 7 also makes way more sense than messing with template files when you already have Grid Infrastructure set up on the cluster nodes.

Luis, I totally get why step 3 feels essential in practice, but the question is asking about the documented procedure for that specific conversion scenario, and the official steps listed in A are what Oracle's documentation calls out as required there, with CLUVFY being a prerequisite you would have already completed before reaching this stage of the process. Worth re-reading the stem to see what phase they are describing, and see if others here agree.
