Design And Development Of Oracle Database System
                     Design And Development Of Oracle Database System
The optimal performance of the 
Oracle database starts with the 
design, and this continues for the 
whole life of the database system. 
Businesses should meticulously 
consider performance issues in 
the initial design phase so that 
the system can be effectively 
tuned easily during the 
production stage.

An Overview Of The Methodology Of Oracle 
The performance of the database system is very 
crucial today as computer systems are getting bigger 
and more complex thanks to the role of the 
Internet in business applications. To accommodate the 
above, Oracle has created a performance 
methodology over time to improve the design and 
performance experience of the system. This 
methodology is a guideline that lays down simple and 
defined activities that improve the performance of the 
system by

very large extent.
Performance Strategies And Their Role In The 
System 
The strategies for performance differ in effectiveness. These systems have different goals, like 
systems for operations and systems for decision support. Each need customized performance 
skills. The system performance is created and in-built in the system. Issues in performance 
generally arise due to contention or the exhaustion of a system resource. When the system 
resource becomes exhausted, businesses experience downtime. With the elimination of these 
issues, Oracle database systems can be made scalable to meet a higher level of performance. 
The Oracle methodology needs to be placed on careful planning and design of the system to 
stop resources from exhausting and causing downtime in businesses. When resource conflicts 
are eliminated, these systems can be made scalable to the levels that the business needs.
1.Options For Investment
Most businesses make an effort to improve performance as memory, disk 
drives, high-end processors, and other system resources are extensively 
available and affordable. So, business owners resort to buying better 
CPUs, more disk drives, and memory to get an immediate improvement in 
performance. However, Oracle database consultants state any immediate 
performance booster is just a short-term remedy to a current issue. If the 
load and the demand on the database increases, the same problem will 
again surface in the future. 
In some scenarios, extra hardware will improve the performance of the 
system. However, if the system has been designed poorly even after 
adding better hardware, its performance is not boosted. Before you buy 
new hardware for supporting the system, ensure there is no single 
threading or serialization in the application. In the long-term, it is prudent 
to increase the functionality of the application as per the number of 
resources you have physically utilized for every transaction occurring 
within the business.
2. Know The Scalability Of The System
Experts in Oracle DBA consulting state one should 
understand the scalability of the system to implement 
changes to boost its performance. One should 
understand the importance of scalability for the optimal 
performance of the Oracle database system. It means 
the ability of the system to process additional workload 
with a proportional surge in the usage of system 
resources. For instance, if the workload on the system 
doubles, the number of resources used for it increases 
as well. The system deploys twice the number of system 
resources it needs for the process. This sounds natural 
and obvious; however, because of system conflicts, the 
uses of resources might supersede twice the initial 
workload.
Poor Scalability Of Oracle Database Management System
The following are some instances of poor scalability- 
● There is an increase in applications that need concurrency management when the 
user population rises
● There is a surge in locking activities
● There is an increase in the workload of data consistency
● There is an increase in the workload of the operating systems 
● There is an increase in data access in transactions when the volume of data 
increases
● The presence of poor index design and SQL result in a larger number of logical 
input and output for the same number of returned rows
● There is reduced availability as the objects of the database take more time to 
maintain
Exhaustion of system resources
Experienced Oracle database consultants add an application that becomes 
unscalable when the system resources are exhausted to such a level where no 
additional throughput is possible after the workload increases. These applications 
result in very poor response time and fixed throughputs. The following are some 
instances of the exhaustion of system resources-
● Exhaustion of hardware
● Memory allocation that results in swapping and paging
● Table scans for high-volume transactions that result in unavoidable disk input 
and output shortages
● Excessive requests for the network that cause bottlenecks in-network and 
schedule.
● Excessive thread allocation and process resulting in system crashes. 
Therefore, when it comes to the design and the 
performance of any Oracle database system, the 
above factors need to be taken into consideration. 
Applications should be designed in such a way that 
they have short evaluation periods. If the design of the 
Oracle database is bad and poor, this means you 
need to take out time and re-implement and re-
architect the system in the future to arrest issues that 
arise with time.
