The Profiler is a tool to help identify resource requirements. Create a profile of your primary Oracle MaxRep Replication Engine to gain valuable insights to information such as data change rates on the primary LUN, data compressibility, required bandwidth to achieve the given recovery point objective (RPO), and required storage.
Profiling helps to accurately predict resource requirements between sites and on the secondary Oracle FS System. During the profiling process only data change rates at the primary Replication Engine are observed. No actual data replication occurs.
To attain higher levels of accuracy, profiling should span at least two weeks. Ideally you should capture relevant daily, weekly, and monthly processing jobs that might impact the source LUN data. Expanding your profile criteria provides you with a statistically significant amount of data.
What is the total storage capacity required for backup and disaster recovery of selected LUNs?
What is the bandwidth required for a near zero RPO?
What is the amount of bandwidth saved due to compression?
Does the currently provisioned bandwidth suffice for a continuous backup or disaster recovery (DR) implementation?
What is the storage required on the secondary server for the desired retention window?
How are the data changes distributed throughout the day, week, or month?
What is the bandwidth requirement for a desired RPO?
