Loading Real and Dummy Data
When you load data into Oracle LSH, you must declare the data to be either real or dummy data by setting the Blind Break system Parameter. You cannot load real data and dummy data at the same time. However, only one Program or Load Set can write data to any particular Table instance. Different technologies require different approaches to populating the real and dummy data partitions of blinded Table instances.
Note:
Oracle LSH cannot ascertain whether data in an external system requires blinding or not. You must set up your security system so that only people who understand the issues and the source data can run Load Sets that may load sensitive data.
