A value of true for the parameter VRS_DB_HINT_ENABLE on Application Parameters will enable the usage of the Database Optimization Hint on the pages appropriately set up on Page Preferences. Any other value will disable the usage of the Database Optimization Hint throughout the application, regardless of the settings on Page Preferences. Note that the application server will need to be restarted for a change to the value of VRS_DB_HINT_ENABLE to take effect.
