The Validation Process
Validation can be done in any of the following ways:
Analysis performed on the production system and validated on the production system.
Analysis performed on the test system and validated on the production system.
Analysis performed on the production system and validated on the test system.
Analysis performed on the test system and validated on the test system.
Note: It is recommended that the last two options not be used during validation because
the collected statistics are from the local system and a test system is usually an
emulated production system where the table data does not exist.
When the analysis and validation are performed on the same system, you can select
the recommendations from the QCD and leave the Validate on Another System unchecked.
When the analysis is performed on one system (test system) and the validation is performed
on another system (production system), the following scenarios can occur:
The user is logged on to the system where the workload is analyzed and wants to validate
on another system. In this case, check the Validate on Another System option in the Load Recommendations from QCD window to log on to the system on which validation must be done. Additionally, the
recommendations can be loaded using either the QCD or the file, if they were saved
at the time of analysis.
The user is logged on to the system where the validation is to be performed. In this
case, the recommendations can be loaded from QCD (if the analysis results are available
on this system by importing of the recommendations earlier) or from the file that
was saved at the time analysis was performed.
