This is bit off-line topic(DBA Track) for sizing process in new EBS installation. Line managers, infrastructure heads, IS team, DBA and Implementation Leads must have to understand some key points for sizing as:

  • Sizing is a complex, iterative process and must be treated with care during the implementation.
  • It should not get conflicted as Sizing a mere calculation rather it a process.
  • Sizing is a project in its own right (PC, network, middle-tier and database-tier). Network is often forgotten in sizing projects.
  • System sizing and architecture goes a long way in determining the TCO of the software
  • It potentially means ability to grow vertically(Module wise) and Horizontally (Data)'
  • Customer, hardware vendor and the consulting patner should work together to find the best sizing strategy.
  • Your database Size should be based on benchmarks and collective experience of Oracle, H/W vendor and knowledge gained from existing customers.
  • Sizing process should not be confused with capacity planning, as both are different parameters.
  • Scaling & load balancing requirements can influence the architecture landscape
  • Validation of assumptions is key.
  • Predicting the batch processing load should not be ignored during an ERP sizing study. Batch loads may be a more important a factor than online requirements.

handFactors which decide some key drivers for sizing are:

  • Number of named users
  • Number of concurrent Users
  • Number of Concurrent Manager (CM) Process
  • Business Event
  • Business Intelligence (BIS)
  • Reporting
  • Number of years online data retention
  • Business volumes
  • Platform & H/W preference

Those who are looking some more granular details for sizing, there is one nice document from Oracle.
