"ORA-00439: feature not enabled" Error on Oracle Database 19c Enterprise Edition

in Database Utilities (MOSC) 6 commentsAnswered

We recently installed Oracle Database 19c Enterprise Edition and on latest July 2024 patch. I wanted to apply Transparent Data Encryption and when running this statement:

ALTER SYSTEM SET "_TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM" = 'AES256' SCOPE = BOTH SID = '*';

I received an error message:

Error: ORA-00439: feature not enabled: Transparent Data Encryption

We are running Enterprise Edition with licensing for Oracle Advanced Security. How can we resolve this error?

Howdy, Stranger!
