Introduction to the Oracle Server Technologies

T

his chapter describes the entire Oracle product family, the concepts behind relational databases, the SQL language, and the role of the database administrator (DBA) in the IT environment. The content is not directly tested in the OCP examination, but it is assumed knowledge that provides an essential background to the study of Oracle database administration. It also gives an idea of the scope of a DBA’s work. The DBA is often expected to know everything about everything. Well, that isn’t possible—but at least he/she should be aware of the whole environment and how the parts link together. The Oracle server technologies product set is more than a database. There are also the Oracle Application Server and the Oracle Enterprise Manager. Taken together, these are the server technologies that make up the Oracle Grid offering. Grid computing is an emerging environment for managing the complete IT environment and for providing resources to users on demand. Supplied with the server technologies are the development tools: third-generation languages (3GLs) and rapid application development tools. It is also possible to write software in a wide range of third-party application development environments. Oracle Corporation has a total commitment to supporting international standards for data processing, which means that it is perfectly possible to run third-party products on the Oracle technology stack.

    To create a database environment for Smith Consulting so they can track their consulting staff, each staff’s member skill sets, and what projects they are working on, they require the installation of a databases setup such as, Microsoft SQL Server, DB2, or Sybase in their machines as well as a separate server room for the database to maintain the connections and servers. To handle this database environment, the Smith Consulting also requires database administrators for each database who can maintain the database at every situation and make it easily accessible to the users who are working on it. (Verdiem Corporation, 2014) This is a kind of decision making process is one in which the management needs to decide which server they need to install so that they achieve the above mentioned goals within the organization. Let’s assume the management installed the Oracle database environment in their machines as well as in the separate database room. Now it is responsibility of the database administrator to properly handle the database environment so it is mostly recommended by all of the DBA’s to install the database server at a remote location which makes it less likely to be hacked and adds stability while using it. Another important role of the DBA is to have proper access to the database and based on the requirements and specifications to assign the permissions for the database to the management such as read, write and execute permissions. This will create the scenario of giving write permissions to the HR department which normally handles the new and old employees staffing. Now the HR department will update about the staff’s projects which means, which employees are allocated to which project and which employees are yet allocated to any projects. Write permissions are also given to the managers of every…
