Verilerimiz 'dururken' şifrelenmesi gerektiğinden , birkaç veritabanını yansıtma ve şeffaf veri şifreleme (TDE) kullanma gereksinimim var .
Hem ana hem de ayna üzerinde TDE ayarladım. İki veritabanının yansımasını oluştururken karşılaştığım sorun ortaya çıkıyor. TDE kullandığım için gui aracılığıyla yansıtma kurmanın bir yolunu bilmiyorum, bu yüzden işi yapmak için t-sql kullanmak zorunda kaldım.
Yansıtılmış sunucuda kullandığım kod aşağıdadır
--Restore the full backup to the mirrored mdf and ldf
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
RESTORE DATABASE TDE
FROM disk = '\\SERVERNAME\SQL_Stuff\Backup\TDE_FULL.bak'
WITH NORECOVERY,
REPLACE,
MOVE 'TDE' TO 'E:\TDE.mdf',
REPLACE,
MOVE 'TDE_log' TO 'G:\TDE.ldf'
CLOSE MASTER KEY
GO
--Restore the log backup to the mirrored db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
RESTORE LOG TDE
FROM DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_LOG.trn'
WITH NORECOVERY;
CLOSE MASTER KEY
GO
--Drop/Create Mirroring endpoint on mirror
--DROP ENDPOINT TDE
CREATE ENDPOINT TDE
STATE = STARTED
AS TCP ( LISTENER_PORT = 7025 )
FOR DATABASE_MIRRORING (
ROLE = PARTNER
);
GO
--Check the endpoints for the mirror
USE MASTER
SELECT * FROM sys.database_mirroring_endpoints
GO
--Set the principal on the mirrored db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
ALTER DATABASE TDE SET PARTNER = 'TCP://PRINCIPAL.DOMAIN.local:7022'
GO
CLOSE MASTER KEY
GO
Aşağıda ana sunucuda kullandığım kod var.
----------------------Mirroring Section----------------------------------
--Full Backup of Principal
USE TDE

BACKUP DATABASE TDE
TO DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_FULL.bak'
WITH COMPRESSION,

GO
---Log Backup of Principal

GO
--Check the endpoints for the princple
USE master
select * from sys.database_mirroring_endpoints

--Set the mirror db on the principal db

Yansıtma uç noktasını önce 1, sonra ana uç noktayı ayarladım. Sonra ALTER DATABASE
aynada, daha sonra ilk hatayı, burada ortaya çıkan hatayı almak sorunu :
Msg 1416, Level 16, State 31, Line 2
Database "TDE" is not configured for database mirroring.
Bu konuda ne yapacağım konusunda bir kaybım var. Ayna "geri yükleme" durumunda, ancak hatanın asıl db hakkında konuştuğundan eminim.
Verebileceğiniz herhangi bir yardım için teşekkürler!
