The number of concurrent users and transactions
The expected response time and throughput
The size and complexity of the data and transactions
The network bandwidth and latency
The configuration and topology of your servers, clusters, and load balancers
The software versions and patches of your Oracle Fusion Middleware components
Based on these parameters, the spreadsheets calculate the following metrics:
The CPU utilization and memory consumption of your servers
The disk space and I/O requirements of your databases
The network traffic and bandwidth consumption of your applications
The scalability and availability factors of your system
The recommended hardware specifications and software configurations for your system
The spreadsheets also provide graphs and charts that visualize the results and show the trends and patterns of your system's performance and capacity over time. You can use these graphs and charts to compare different scenarios, identify bottlenecks, and plan for future growth.
Why use Oracle Capacity Planning and Sizing Spreadsheets?
Oracle Capacity Planning and Sizing Spreadsheets can help you achieve the following benefits:
Reduce the risk of under- or over-provisioning your resources, which can lead to poor performance, wasted costs, or unmet service level agreements (SLAs).
Optimize the performance and scalability of your applications by finding the optimal balance between resource utilization, response time, throughput, and availability.
Improve the reliability and availability of your applications by designing a robust architecture that can handle peak loads, failover scenarios, and disaster recovery situations.
Save time and effort by using a standardized and proven methodology that is based on best practices and real-world experience from Oracle experts.
Gain insight into your system's behavior and trends by collecting and analyzing historical data from various sources, such as monitoring tools, logs, reports, or benchmarks.
How to use Oracle Capacity Planning and Sizing Spreadsheets?
To use Oracle Capacity Planning and Sizing Spreadsheets, you need to follow these steps:
Download the spreadsheets from the Oracle Technology Network (OTN) website. There are different spreadsheets for different Oracle Fusion Middleware components, such as WebLogic Server, SOA Suite, WebCenter Portal, Identity Management, Business Intelligence, etc. Choose the spreadsheet that matches your application's requirements.
Open the spreadsheet in Excel and enable macros. The spreadsheet contains several worksheets that correspond to different aspects of capacity planning and sizing, such as assumptions, inputs, outputs, graphs, etc. You can navigate between the worksheets using the tabs at the bottom of the spreadsheet.
Fill out the assumptions worksheet with some basic information about your application, such as its name, description, purpose, scope, etc. This worksheet also contains some default values for some parameters that are based on industry standards or typical scenarios. You can modify these values if they do not match your application's characteristics.
Fill out the inputs worksheet with more detailed information about your application's parameters, such as the number of concurrent users, transactions per user per hour, transaction size, response time, throughput, etc. You can use various sources of information to obtain these values, such as business requirements, user surveys, historical data, benchmarks, etc. You can also use the spreadsheet's built-in formulas and functions to calculate some of these values based on other values.
Review the outputs worksheet, which shows the results of the calculations based on your inputs. The outputs worksheet contains several tables and charts that display the metrics related to your system's performance and capacity, such as CPU utilization, memory consumption, disk space, network traffic, scalability factors, hardware specifications, software configurations, etc. You can use these outputs to evaluate your system's current and future state, identify potential issues or gaps, and make adjustments to your inputs or assumptions as needed.
Save the spreadsheet and document your findings and recommendations. You can also share the spreadsheet with other stakeholders, such as developers, testers, administrators, managers, etc., to communicate your capacity planning and sizing results and obtain feedback or approval.
Conclusion
Oracle Capacity Planning and Sizing Spreadsheets are useful tools that can help you plan and optimize your Oracle Fusion Middleware applications for performance and scalability. They can help you estimate the hardware and software requirements for your applications, monitor and manage the resource utilization and consumption of your applications, and design a robust and reliable architecture for your applications. By using these spreadsheets, you can reduce the risk of under- or over-provisioning your resources, improve the performance and availability of your applications, and save time and effort by following a standardized and proven methodology.
