It can be challenging for customers to fine tune the underlying infrastructure and software solution for Oracle database deployments, as research can be time intensive and confusing. Software and hardware vendors often provide lengthy documentation on how to tune their products for performance optimization and some may even provide specific best practices for specific products, but that does not mean these solutions will work optimally with other components in the solution. Solution performance optimization using this type of process requires constant observations and testing to determine a set of best practices for the whole solution. Each component in the solution must be tuned individually and then combined with other components to ensure that the system functions optimally. Those components in the infrastructure solution consist of:
Tuning exercises must also be conducted on a separate environment such as test or dev to avoid any problems that could arise when implemented on production. Optimal performance tuning also varies from system to system, meaning determining best practices can require a lot of trial and error.
