Installing the oracle with TDE feature

Dear All,

We are planning to perform Transparent Data Encryption for our oracle 11.2 database (PRD) using system copy (R3load) method.

Could you let me know, for the following:

we are performing system export (QAS) -import (PRD) method:

1. Do we need to perform any steps before we do QAS export, or after the export?

2. Do we need to perform any steps before we start the data import for PRD import?

3. As per the sap notes, it is understood that we need to create database wallet, and perform the encryption of tablespace

along with the data migration.

I am reading notes 0000974876, 1586304; Very much appreciative, if you can share your experiences, and thoughts.

Thanks and Regards

Purna
