If you rename a file with alter database on primary, it will not occur on standby. If you want to rename it on standby to, you need to do it manually
- cancel the recovery (set dg_broker_start to false and restart db in mount status if you use dataguard)
- set the standby file management to manual alter system set standby_file_management=manual
- move the file with OS commands as you did on the primary
- rename the file with alter database rename file ‘old’ to ‘new’
- reenable automatic standby file management and dg broker and restart the recovery (start db in mount status if you use dataguard)
