I have a 9.2.0.3 DB running on AIX 4.3.3
An application running on W2K using SQLLDR to load approx 6g of data
using local managed tablespaces
ie..
CREATE TABLESPACE PARENTDAT
DATAFILE '/vol01/oradata/e450dev/parentdat01.dbf' SIZE 2000M REUSE,
'/vol01/oradata/e450dev/parentdat02.dbf' SIZE 2000M REUSE,
'/vol01/oradata/e450dev/parentdat03.dbf' SIZE 2000M REUSE,
'/vol01/oradata/e450dev/parentdat04.dbf' SIZE 2000M REUSE
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M
NOLOGGING
ONLINE;
It was taking 8 hours to load this data
1) copied the data to the AIX box and ran SQLLDR local to the DB and
received similar results
2) changed the tablespace to contain 1 8g datafile
3) ran SQLLDR from the W2K machine ..completed in 30minutes
Also
ran the same test on AIX 5.1 running oracle 9.2.0.3 and obtained the same
results.
I really would like to be able to create the tablespaces with multiple data
files but it seems whenever I add a datafile the
performance of the load degrades.
Any ideas??
Thanks in advance
John
