Database Administration with Oracle

Database management systems can be divided into two categories namely, desktop databases and server databases. The principle use of any database manement system is to store, organize, and retrieve information for business and/or financial purposes. Desktop databases are designed for single-user applications loaded onto standard personal computers. Desktop databases provide simple solution to many less complex data storage and manipulation requirements. Popular Desktop DBMS are Microsoft Access, FoxPro, FileMaker Pro, Paradox and Lotus Approach. Server databases, on the other hand, facilitate big corporates and organisations to manage large volumes of data efficiently. Server Data bases such as Microsoft SQL Server, Oracle and IBM DB2, offer organizations the ability to manage data in a manner that enables many users to access and update the data simultaneously.

Oracle - The Advantages

Oracle is a very complex and powerful product, and part of its power lies in its ability to get the best possible performance out of each individual database configuration, maximizing performance is hierarchical in nature. Oracle Database is probably the best-known of all of the DBMS software applications. It quickly established itself as a robust, database management system in the business world. Unlike its competitors which are primarily user-based and resident on local computers, Oracle Database is primarily a server-based system which requires the services of certified database administrators and database engineers.

Oracle can handle just about any data management problem. Developers favors this system because it has programmer-friendly application programmer interfaces, APIs that provide for the rapid development of database oriented custom applications. The Oracle platform is even available for multiple operating systems. Oracle is as powerful as it is expected to be. Oracle which is modern database administration tool, can manage multiple high-speed processors, clustered servers, high bandwidth connectivity and fault tolerant storage technology. If the necessary hardware resources are provided, Oracle is able to gracefully handle a rapidly expanding amount of users and/or data.

Oracle - How to extract maximum performance

Oracle-based database administration is dependent on three major factors for better, optimised performance. These areas are Operating system configuration, Oracle resource configuration and Object creation and SQL execution. Basically, you cannot hope to get good performance out of Oracle unless and until you have properly configured and tuned your operating system. Likewise, good query execution depends on a properly configured Oracle environment. In most installations, there is a system administrator or manager who is responsible for addressing operating system and hardware issues. This system administrator is usually an expert on the hardware and operating system software, and most DBAs are not in a position to second-guess him or her.

Physical memory should be fully utilized, but swapping (in environments that swap memory) should not occur. In particular, make certain that you do not create a System Global Area (SGA) that is too big for physical memory, since swapping of the SGA will severely degrade Oracle performance. The CPU should approach 100% utilization at peaks, but processes should not have to wait for the CPU. Disks and controllers should be running at or near their optimal capacities (usually 60 to 90% of maximum) with minimal I/O waits. As the DBA, you do have some control over this area as well.

Network throughput should not be a bottleneck. Consider backbone networks to link servers to each other, and separate client/server traffic from server/server traffic where possible. Try to keep your Oracle server machine a pure server, and move users to another machine. Be sure any operating system components (including patches) that may affect Oracle are installed. Because Oracle is a major vendor in the database marketplace, most major hardware vendors have Oracle "experts" on staff who can provide advice on hardware and operating system issues that may affect Oracle's execution on their hardware. Oracle's overall performance is affected by the components that are installed, as well as by how those components are configured. A high-performance Oracle database is essential to obtaining maximum performance from transactions run against that database.

Conclusion

Oracle has become over the years, a highly popular database administration system. If adequate care taken while installation, Oracle will give an excellent performance. Oracle is today platform-independent and can be installed on all major operating systems. Multiple users and large volume of data are efficiently stored, manipulated and retrieved by deploying Oracle. Developers today are bringing up several tools and applications which can be combined with Oracle for better database administration.
