To learn Oracle 1Z0-007, first of all to learn the architecture of Oracle, now you do not need in-depth understanding of them, but to distinguish a few key concepts:
instance & database, memory structure, process & those files, such as data file, control file, init parameter file etc and the database, tablespace, data file and tablespace, segmnet, extent & block the relationships between them.

You want to learn some simple hands-on, is how to manage Oracle 1Z0-007 database, of course, not to manage all of the Oracle. In this process, you will have SQL and Oracle architecture has a better understanding.

This step is basically to be your initial grasp of the Oracle, the following will be under the direction of your specific learning other knowledge of Oracle Certification. If you are a developer, you need more to learn PL / SQL, and DEVELOPER, and this will be a new course. If you are a DBA, please continue.

You can according to their actual situation, to have a choice of learning content that is not specifically order the following requirements. Oracle 9i DBA Certification may choose to study in depth the management, backup and recovery, performance tuning, network. Of course, the knowledge in the learning process, if there is a practical work better, so you can actually grow, learn TROUBLE SHOOTING.

Testinside summarizes a lot about learning Oracle 1Z0-007 and 1Z0-042 method, you can come back to, and learning together with people of the certification exams exchange. When the 1Z0-007 to generate a database table space segment, the effective free space from the table space for the initial scope of this section allocated space. Full range of these initial data, the section would request to add another range. This expansion process will always continue until the maximum range values, or space in the table has no free space for the next range.

When a space to meet the requirements, 1Z0-042 will first search the current database, the largest free range, and “maximum” free range became smaller and smaller, to find a large enough range of freedom has become increasingly difficult, leading to the table space speed of obstacles to the database space allocation increasingly away from the ideal state.
