Oracle Database Discussions

Hi

I am working in oracle 11gR2. I got request for column encryption from my client. I read something about TDE and created wallet through sqlnet.ora file.

after login to the database i made,

alter system set encrytion key authenticated by "password";

then I thought to change the password but I don't know how to do it. then I planeed to remove wallet instead of that i removed ewallet.p12 file from os level.

I have seenone column is encrypted, when i trying to select * from t am getting below error,

ora-28362:master key not found

How to remove the wallet or reset the password? and I want to create one fresh encryption wallet.


Thanks in advance.
