El examen OCM no es un juego es uno de los examenes mas fuertes de oracle y con mayor duracion (2 días) ; se necesita mucho conocimiento, así como rapidez en el trabajo para resolver problemas, para aprobarlo. Aquí enumeraré los temas y algunas guías de estudio para cada uno de ellos, para poder intercambiar con ustedes que también están solicitando, interesados o tienen conocimiento. Cada tema tendrá un enlace a una publicación donde iré cubriendo algunos casos de prueba, lo que se necesita estudiar y el enlace al documento oficial de Oracle. Recuerde, el Documento Oficial de Oracle es todo lo que tendr...
