Segue uma dica para momentos difíceis como os lock por ddl :

Eliminar sessões maléficas :

select 'alter system kill session ''' || ddl.session_id || ',' || ses.serial# || ''' immediate;'
from dba_ddl_locks ddl
, v$session ses
where owner like '%userid%'
and ddl.session_id = ses.sid

Rode o resultado da query .

Trabalhando com Triggers

Segue algumas dicas para quem trabalha com triggers no seu schema .

Listar as triggers do SGDB por Schema :
