1. The parameter that controls file naming at the standby is set so the apply process renames a data file itself when the redo describes a new path
2. The parameter that controls file sizing at the standby is set so the apply process extends a data file itself when the redo describes a new extent
3. The parameter that controls file checking at the standby is set so the apply process verifies a data file itself when the redo describes a new block
4. The parameter that controls file creation at the standby is set so the apply process creates a data file itself when the redo describes a new one
