I will answer question 2 first. Try looking at this:
1 select to_char(to_date('9912101400','YYDDDSSSSS'),'YYYYMMDD
HH24:MI:SS')
2* from dual
OPS2> /
TO_CHAR(TO_DATE('
OPS2> select to_char(to_date('99121','YYDDD') + 1400/86400,'YYYYMMDD
HH24:MI:SS')
2 from dual
3 /
TO_CHAR(TO_DATE('
As for question 1 well:
1) Larger DB block size provides more space to hold rows before a new
block must be obtained when empty blocks can be used, but changing the
Oracle block size requires a database rebuild
2) Allocate multiple free lists to the table/indexes and run 2 insert
jobs to reduce clock time, but not Oracle work.
3) Use sqlldr with direct load.
