Actions Taken
The FRA space alert has been taken care by adding the space from 3.5TB to 4.5TB.

Before adding space:
select round((SPACE_USED/SPACE_LIMIT)*100) from V$RECOVERY_FILE_DEST;

ROUND((SPACE_USED/SPACE_LIMIT)*100)
———————————–
77

After adding space:
select round((SPACE_USED/SPACE_LIMIT)*100) from V$RECOVERY_FILE_DEST;

ROUND((SPACE_USED/SPACE_LIMIT)*100)
———————————–
66
