Create 12.2.0.1 Multitenant Database with DBCA

Here is an example of how to create a multitenant oracle database with DBCA in Oracle 12.2.0.1.

We will create a multitenant database with 1 CDB and 1 PDB. For CDB, all the components are selected and installed.  But for PDB, only following three components are selected and installed :

Oracle JVM 
Oracle Text
Oracle Multimedia

1)Startup VNCSERVER on node 1.

[oracle@racnode1 ~]$ vncserver :1

New 'racnode1.virtuallab:1 (oracle)' desktop is racnode1.virtuallab:1

Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/racnode1.virtuallab:1.log

[oracle@racnode1 ~]$

2) Open VNC Viewer .

3) Startup DBCA.

[oracle@racnode1 ~]$/u01/app/oracle/product/12.2.0/dbhome_1/dbca

4) Choose “Create a database”
“Advanced configuration”
“Custom database”
“Select all” nodes
Put in Database Name, SID, PDB details.
…
..
.

Choose ASMM in memory option, otherwise you will get below error:

[DBT-11211] The Automatic Memory Management option is not allowed when the
            total physical memory is greater than 4GB.

5) check the database.

[oracle@racnode1 ~]$ srvctl status database -d RACTESTB
Instance RACTESTB1 is running on node racnode1
Instance RACTESTB2 is running on node racnode2
[oracle@racnode1 ~]$
