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.

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.

2. 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 Cloud
Application Development Gurgaon to a very large
extent.

3. 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.

4. 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.

5. 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.

6. 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

7. 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.

8. Original Source - Design And Development Of Oracle Database System
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.
