Performance Issue
Posted: Fri May 06, 2011 11:23 am
Basically we are loading from Sybase to Oracle tables, it takes close to 30 mins. for loading 2 million records. It is direct mapping and no validation.
For the first run it will be full referesh but then onwards it would be delta records. Hence we are using a upsert process (Update then insert)
SYB -> TRN -> ORA
Apart from this when we add a column to the existing record and load the overall load time for 2 million records is 1 hour.
Any suggestions on how to bring the load time down please.
Thanks
