ORA-01078 When running Dbca Delete Database

When trying to delete a database by running dbca, the following errors appear:

$  dbca  -silent -deleteDatabase -sourceDB TESTDB -sysDBAUserName sys  -sysDBAPassword "sys_password"
ORA-01078: failure in processing system parameters


  1. Remove the entry in /etc/oratab for this database to be deleted.
  2. Make sure here sourceDB name is actually UNIQUE_DB_NAME, instead of DB_NAME. 
$  dbca  -silent -deleteDatabase -sourceDB TESTDB_UQ sysDBAUserName sys  -sysDBAPassword "sys_password"
