The tablespace will be create inside of Pluggable Database: PDBPROD3

Datafile location: /u02/oradata/cdbprod/pdbprod3/
 Keystore location: /u01/oracle/admin/$ORACLE_SID/encryption_keystore/

1.) Include in SQLNET.ora:
 ENCRYPTION_WALLET_LOCATION =  
(SOURCE =(METHOD = FILE)(METHOD_DATA =    
(DIRECTORY = /u01/oracle/admin/$ORACLE_SID/encryption_keystore/)

2.)Create the directory, if doesn’t exist:

mkdir -p /u01/oracle/admin/$ORACLE_SID/encryption_keystore/

3.)Create the KEY store:

$ cd /u01/oracle/admin/$ORACLE_SID/encryption_keystore/
$ pwd
/u01/oracle/admin/cdbprod/encryption_keystore

Inside of Root Container execute:
