We’re working through a Cloud upgrade with a remote deployment. I’m running into a lot of performance issues, and I’d like to explore using different antimalware solutions, different public clouds, and different on-prem hardware. Whenever I copy our production database somewhere, though, it creates a significant business risk, so I need a full-sized copy of our system that has been made safe enough to use for this exploratory purpose.

 

I need to mask or sanitize our entire database to reduce or eliminate the risk of our business data getting compromised.

 

Question 1: Has anyone scrubbed a database like this? How did you do it?

 

There’s a pack available for Oracle Database Enterprise Edition called the Data Masking and Subsetting Pack. I saw that it needs to be licensed for the source database, or in this case our PROD 9 database.

 

Question 2: Does this pack need to be licensed for every user or just the IT users who are working in the sanitized environment?

 

Even if I can manage to mask all the fields myself, I’d have to mask both sides of each referential integrity constraint. This isn’t so bad for well-behaved fields that are just keys, but the system includes several columns like KEY_REF and KEY_VALUE that would need to be remapped as well.

 

Question 3: If you’ve done this before, how did you mask partial column values? If you’ve used the Oracle pack to do this, did it cover partial keys?

Our system has over 100K columns and 6K tables, and the Oracle EE pack would require a prohibitive amount of data entry into Enterprise Manager.
