Hi Arthur, welcome to the guide "DBCA: Software + DB Creation"
With this guide, you will be able to teach Marvin how to get Oracle Databases on your RAC cluster
We are assuming you already have your Software downloaded and ready in node1 of your cluster.
If that is not the case, please go to Oracle Database Software Downloads
or to Oracle Software Delivery
On these cases, we are creating the DB assuming not only some of the
default configuration settings, but also assuming the "oracle_home"
software has not "SQL patches" or "Bundle Patches" on them.A good practice is always to check the system for invalid objects
after its creation and in some cases, execute "datapatch" (for 12c+
systems) and scripts like "utlrp.sql" or "catbundle.sql" to make sure
the DB has all its objects valid and all patches actives.Have a look to these articles for more info on this:
Do you have to execute catbundle.sql when you create a new 11g
database?Do you have to execute “datapatch” when you create a new
database?
DBCA 12c and "datapatch.pl" - things to
know
Oracle 11.2.0.4 Silent Installation
Get 11.2.0.4 files from MOS, since OTN files are 11.2.0.1
https://updates.oracle.com/Orion/AdvancedSearch/process_form?search_style=9&language=0&patch_type=patchset&incl_prod=&incl_prod_checked=yes&release=80112040&plat_lang=226P&product=9480#query_linkFiles:

p13390677_112040_Linux-x86-64_2of7.zip Unless you want to install
11.2.0.1 and then upgrade to 11.2.0.4... Im sure that is also fun!!
In order to be able to install 11g Software as RAC we will need to make sure CRS flag is present in the Inventory.xml.
Is possible you wont need to change anything, but on some cases you will be prompted with some errors if this is not set explicitly since DBCA wont "see" the cluster

What we are going to do first, is just install Oracle DB Software.
Let's create a response file for "Software only" making sure we have correct "oracle.install.responseFileVersion" and "oracle.install.db.CLUSTER_NODES" is listing all RAC cluster nodes:
[oracle@rac1-node1 database_11.2]$ cat db_swonly.rsp
## db_swonly.rsp ##
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0

SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
oracle.installer.autoupdates.option=SKIP_UPDATES
Now, we just need to execute DBCA in silent mode with the response file created and the system will make sure DB software is installed in both RAC cluster nodes:
[oracle@rac1-node1 database_11.2]$ ./runInstaller -silent -responseFile /u01/Installers/database_11.2/db_swonly.rsp -showProgress -ignorePrereq

Remember to read the output in your screen (I know.. is not always the most exciting part, isn't it..?) and execute the root script as root in all of the RAC cluster nodes:

[root@rac1-node2 ~]#
Since we have now the Software in place, we will be able to create a DB on that.
For this part of the journey, we are just creating a DB with most of its default option.
We will explore DB templates personification under DBCA: Modify Templates and clone Database

Lets create our first Database now that we have the software ready.

Since we are talking about 12c database, shouldn't we try to create the Database as container and add a couple of PDBs?... yeah.. lets do it.

Now, you can confirm that the DB is running in all cluster nodes and add the Instances entries to oratab:
[oracle@rac1-node2 ~]$ srvctl status database -d db122 -v
Instance db1221 is running on node rac1-node1. Instance status: Open.
Instance db1222 is running on node rac1-node2. Instance status: Open.
[oracle@rac1-node1 bin]$ cat /etc/oratab

Like we did in 12.1, we can create a container DB with couple of PDBs
PDBs Services Conflict
To avoid PDBs automatic service conflicts, avoid creating the PDBs
with same name as they have in other Container even if they are
different versions. The system will prompt to an error if it tries to
create "PDB1" in more than one container since the "listener service"
will be called the same
## Command Example ##
/u01/app/oracle/product/12.2.0/dbhome_1/bin/dbca \
-silent \
-createDatabase \
-templateName General_Purpose.dbc \
-gdbName cdb122 \
-sid cdb122 \
-createAsContainerDatabase true \
-numberOfPdbs 2 \
-pdbName pdb2 \
-pdbAdminPassword Welcome1 \
-SysPassword Welcome1 \
-SystemPassword Welcome1 \
-emConfiguration NONE \
-storageType ASM \
-redoLogFileSize 50 \
-diskGroupName DATA2 \
-characterSet AL32UTF8 \
-nationalCharacterSet AL16UTF16 \
-databaseType MULTIPURPOSE \
-sampleschema false \
-ignorePreReqs \
-nodelist rac1-node1,rac1-node2
## Output ##

[WARNING] [DBT-10331] Specified SID Prefix (cdb122) may have a potential conflict with an already existing database on the system.
CAUSE: The specified SID Prefix without the trailing numeric characters (cdb) may have a potential conflict with an already existing database on the system.
ACTION: Specify a different SID Prefix that does not conflict with existing databases on the system.

Lets check the PDBs:
SQL> show pdbs;
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB21 READ WRITE NO
4 PDB22 READ WRITE NO
And now, you can see how to create the PDB using DBCA once you have the container ready:
## Command Example ##
/u01/app/oracle/product/12.2.0/dbhome_1/bin/dbca \
-silent \
-createPluggableDatabase \
-sourceDB cdb122 \
-pdbName pdb23 \
-pdbAdminPassword Welcome1
## Output ##
[oracle@rac1-node1 bin]$ /u01/app/oracle/product/12.2.0/dbhome_1/bin/dbca -silent -createPluggableDatabase -sourceDB cdb122 -pdbName pdb23 -pdbAdminPassword Welcome1

I think is enough DBCA exploration for now.
Don't get to frustrated after the first initial errors or mistakes... they are just part of the fun (or that is what Trillian keeps telling me..)
