Personal experiments sometimes use large tables, where you can share the dba_objects to create a test large table:
First set up the test table
Sys@orcl>create table Test nologging as Select RowNum id,a.* from Dba_objects a where 1=2;
Table created.
Insert 5 million data:
Sys@orcl>declare
L_CNT number;
L_rows number:=&1;
Begin
Insert/*+ Append */into Test select rownum,a.* from Dba_objects A;
L_cnt:=sql%rowcount;
Commit
while (l_cnt
Loop
Insert/*+ Append */Into Test select rownum+l_cnt,
Owner,object_name,subobject_name,
OBJECT_ID,DATA_OBJECT_ID,
Object_type,created,last_ddl_time,
Timestamp,status,temporary,

From sales
where rownum<=l_rows-l_cnt;
L_cnt:=l_cnt+sql%rowcount;
Commit
End Loop;
