In another post “How to Install Example Schemas in 12c Database?“, It shows detail steps of how to install example schemas manually through SQL command line.
Here we use another way to install example schemas by creating a PDB with example schemas and plug this PDB into a current CDB .
1) Start up DBCA, select “Manage Pluggable Databases”.
2) Select “Create a Pluggable Database”.
3)Select CDB database to create a PDB in.
4)Select “Create pluggable database using PDB file set”.
5) Select example schemas file set under $ORACLE_HOME/assitants/dbca/templates/
6) Specify PDB name and PDB datafiles location.
7)Review the template summary.
8) Start to create PDB of example schemas.
9) PDB creation is complete.
Verify PDB Creation and Connect to Example Schemas
1) Connect to CDB.

2) Create an entry in TNSNAMES.ora for PDB_SAMPLES.
PDB_SAMPLES = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST =CDBSERVER)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = pdb_samples) ) )
3) Connect to PDB , unlock example schemas and reset passwords.
