ORA-01220:

file based sort illegal before database is open
Cause: A query issued against a fixed table or view required a temporary segment for sorting before the database was open. Only in-memory sorts are supported before the database is open.
Action: Re-phrase the query to avoid a large sort, increase the values of the SORT_AREA_SIZE and/or SORT_AREA_RETAINED_SIZE initialization parameters to enable the sort to be done in memory.
