However, certain tasks are still common to all oracle specialists, such as managing database performance and ensuring database availability, installing and configuring the database, managing and implementing security, and recovering and backing up data. Finally, the oracle specialist performs a technology watch to optimize and evolve the application.
The DBA must have certain well-defined technical skills. He or she plays an intermediate role as a consultant in a company, since he or she will communicate sometimes with the systems team and sometimes with the development team. He or she therefore has knowledge in various fields, which are not strictly speaking databases. However, all his knowledge and skills depend above all on his scope of intervention. Then, on his past experiences as well as his human skills.
For example, some oracle specialists have a high level of competence as an engineer in the field of storage architectures, when his position is targeted towards production. Others will have much more advanced skills in the development part.
As far as the human qualities required in the DBA are concerned, there are four that will be particularly necessary. First, curiosity. Indeed, he or she must be able to explore avenues for continuous improvement and be self-trained. Then comes listening and the ability to dialogue (manager), resistance to stress, and finally, rigor.
As far as training is concerned, the oracle specialist follows a development course with a specialization in databases. The best learning method remains professional experience, which allows the acquisition of the basics of the profession in the field.
