Performance Considerations for Data Cleansing
The following recommendations for data cleansing should help you achieve good performance when working with large volumes of data:
- You can include only new or recently modified records in the batch data cleansing process.
If you run data cleansing on a record twice, sometimes the record can change the second time. However, cleansing all records in the Siebel database each time a data cleansing is performed can cause performance issues. It is recommended you include only new or recently modified records in the batch data cleansing process. These records can be identified using the Object WHERE clause when you submit your server component request, as shown in Table 17.
- You can copy address files to your local machine.
Address data cleansing (for business address and prospect data) needs to access the address data files frequently, so you should copy these files to your local machine.
- You can set the ReservedOption parameter.
For you to speed up the data cleansing task for large databases, set the ReservedOption component parameter to 0 (ReservedOption=0), and then cleanse a smaller number of records at a time using an Object WHERE clause.

- You can split the tasks into smaller tasks and run them concurrently.
