ORA-30036: During Bulk Insert

Question

Hi gurus,
While loading data from stgging table to dimension table we are facing below mention error
ORA-30036: unable to extend segment by 8 in undo tablespace 'UNDOGTAMAC'
we are using below script
INSERT /*+ APPEND */ INTO table_dim (SELECT * FROM TEMP_tab);
COMMIT;
Where TEMP_tab table contains around 2,00,00,000 rows
Can we use sqlloader to achieve it ?
Please advice
Thanks in advance

Where TEMP_tab table contains around 2,00,00,000 rowsYou can do this as a custom parallel-enabled process. You can create a procedure as follows:
create or replace procedure InsertRowRange( fromRow varchar2, toRow varchar2 ) is
begin
  insert /*+ append */ into table_dm
  select * from temp_tab where rowid between fromRow and toRow;
end;You now need to split TEMP_TAB into multiple rowid ranges - let's say 20 ranges. Instead of starting 20 parallel copies of the procedure, each with a unique rowid range, you schedule it as 20 serialised processes.
The only requirement is that TEMP_TAB remains unchanged for the duration of the serialised processing as adding or deleting or inserting rows into it, will cause problems for the rowid range approach.
You can also potentially use the primary key (e.g. date based pk) of the source table to govern what ranges of rows to insert per processing step (e.g. only a single day's rows).
The main thing to stay away from (because of poor design and poor performance) is fetching from a cursor loop, inserting rows, and then committing every x number of rows. This is a horrible and non-scalable approach.
