Problem:
While creating my local domain for POC work , faced the following error while running SOA 12c RCU for creating schemas,

Error:
RCU creation failed due to following error.

RCU-6002:The specified database does not meet the minimum requirement to load metadata repository.
RCU-6080:Global prerequisite check failed - Check requirement for specified database
The selected Oracle database is a multitenant container database (CDB). Connecting to a multitenant container database (CDB) is not supported. Instead, connect to a valid pluggble database (PDB).
========================================================================
Cause: 
The selected Oracle database is a multitenant container database (CDB)
========================================================================
Resolution:
1. Determine if your database has been created as CDB or not using below SQL
SELECT CDB FROM V$DATABASE;
2. Check if any PDBs are available in the Database.
SELECT CON_ID, NAME, OPEN_MODE FROM V$PDBS;
    If there is no PDB other than PDB$SEED, please work with your DBA to create a PDB for the RCU schema
3. If there is a PDB then get full service names using below sql,
select name from v$services;
4. Make sure PDB is open (Mounted doesn't mean it's open). To open PDB run below sql,
alter pluggable database all open;
5. Verify if PDB open by running,
SELECT CON_ID, NAME, OPEN_MODE FROM V$PDBS;
6. Once done you can verify service using "lsnrctl status"
7. Now DB is ready for schema creation using RCU. Connect and create schema.
