Topic 1: The Duties of a DBA
Database administrators play an important role in database management. An Oracle DBA performs several critical functions to the successful management of databases. Each database needs at least one administrator to manage it. However, since an Oracle database system can be large, it isn’t easy to manage it by a single DBA. Oracle DBAs perform certain important functions. One of the main functions of DBAs in Oracle is installing and upgrading application tools and the Oracle server (“Oracle,” n.d.). DBAs ensure that they constantly monitor their oracle databases to ensure that they are always up-to-date. Application tools should also be updated to ensure improved performance and efficient management.
Another important role of an Oracle DBA is allocating system storage and anticipating and planning for future storage needs for the database. Oracle DBAs should always monitor their systems and allocate system storage appropriately. Allocating enough system storage is critical for the performance and efficiency of the database (“Oracle,” n.d.). Planning for future data storage needs is also critical in preparing resources to support such needs.
Once application developers have provided a DBA with the necessary information, they are tasked with modifying the database structure as required. DBAs can modify the database structure to suit their needs and that of their organizations (“Oracle,” n.d.). Oracle DBAs are also expected to ensure that they comply with the Oracle license agreement (“Oracle,” n.d.). The Oracle license agreement stipulates what is expected of both clients and the company. Oracle DBAs should therefore constantly monitor the usage of their databases to ensure that they comply with the Oracle license agreement. Finally, Oracle DBAs are required to back up and restore databases. Databases should be properly backed up to prevent any data losses. An Oracle DBA is expected to back up its databases and implement recovery measures in case of data loss.
Topic 2: The Best OS for Oracle
A relational database management system (DBMS) carries out several critical functions that determine the consistency and integrity of data in the database. The DBMS utilizes the data dictionary to search for components and their relationships. This function makes it easier for users or DBAs to code complex relationships into each program. DBMS also ensures that all changes made in a database structure are updated automatically, saving users from modifying all the programs affected by the change (“Sisence,” n.d.). The DBMS carries out security management by creating a system that maintains data privacy and user security. A DBMS applies security rules that determine the access levels of each user and the functions that they can execute on the database.
Furthermore, data integrity management is a critical role of DBMS. The DBMS ensures the strict enforcement of integrity rules, fostering data consistency and minimizing redundancies (“Sisence,” n.d.). The DBMS also aids in multi-user access control by applying complex algorithms to ensure that several users can access the database simultaneously without compromising its functionality or integrity (“Sisence,” n.d.). A DBMS is an important aspect of any database management process.
The best OS for Oracle is Oracle Linux OS. Oracle Linux (2020) states that Oracle had selected Solaris as its OS in 2005 but decided to develop their OS that is custom made to meet the needs of a typical database. The Linux OS combines the advantages of all the other OS platforms hence ensuring improved functionality.
