RE: Database Encryption

What version of the database are we talking about here? Always helpful knowledge.

If it’s a supported version, I’d open an SR with Oracle, to be honest. You should not be seeing this kind of impact from encryption unless your server was already sitting on the edge. Depending on your version, there are known bugs (and – yes – bug fixes) for problems related to encryption and performance. Where are you seeing your biggest impacts? CPU, IO response times, changed execution plans? What was the command you used to do the encryption? Did you encrypt with or without salt? In other words, what have you done to quantify the problem you are seeing?

Stay the course and figure out this problem would be my suggestion. Don’t just jump ship because you’re taking on a little water.

Yes right... Did not encrypt the system sysaux undo n temp..

All,

We have encrypted almost all the datafiles of the database, post that the performance of the database degraded to almost 40-50%

Could anyone suggest what is the other alternative method that we can use in order to secure data with bit performance impact.

Regards,
Arun
