sys.database_mirroring_endpoints (Transact-SQL)

Applies to: SQL Server

Contains one row for the database mirroring endpoint of an instance of SQL Server.

Note

The database mirroring endpoint supports both sessions between database mirroring partners and with witnesses and sessions between the primary replica of an Always On availability group and its secondary replicas.

Column name	Data type	Description
<inherited columns>	-	Inherits columns from sys.endpoints (for more information, see sys.endpoints (Transact-SQL)).
role	tinyint	Mirroring role, one of: 0 = None 1 = Partner 2 = Witness 3 = All Note: This value is relevant only for database mirroring.
role_desc	nvarchar(60)	Description of mirroring role, one of: NONE PARTNER WITNESS ALL Note: This value is relevant only for database mirroring.
is_encryption_enabled	bit	1 means that encryption is enabled. 0 means that encryption is disabled.
connection_auth	tinyint	The type of connection authentication required for connections to this endpoint, one of: 1 - NTLM 2 - KERBEROS 3 - NEGOTIATE 4 - CERTIFICATE 5 - NTLM, CERTIFICATE 6 - KERBEROS, CERTIFICATE 7 - NEGOTIATE, CERTIFICATE 8 - CERTIFICATE, NTLM 9 - CERTIFICATE, KERBEROS 10 - CERTIFICATE, NEGOTIATE
connection_auth_desc	Nvarchar (60)	Description of the type of authentication required for connections to this endpoint, one of: NTLM KERBEROS NEGOTIATE CERTIFICATE NTLM, CERTIFICATE KERBEROS, CERTIFICATE NEGOTIATE, CERTIFICATE CERTIFICATE, NTLM CERTIFICATE, KERBEROS CERTIFICATE, NEGOTIATE
certificate_id	int	ID of certificate used for authentication, if any. 0 = Windows Authentication is being used.
encryption_algorithm	tinyint	Encryption algorithm, one of: 0 - NONE 1 - RC4 2 - AES 3 - NONE, RC4 4 - NONE, AES 5 - RC4, AES 6 - AES, RC4 7 - NONE, RC4, AES 8 - NONE, AES, RC4
encryption_algorithm_desc	nvarchar(60)	Description of the encryption algorithm, one of: NONE RC4 AES NONE, RC4 NONE, AES RC4, AES AES, RC4 NONE, RC4, AES NONE, AES, RC4

Remarks

Note

The RC4 algorithm is only supported for backward compatibility. New material can only be encrypted using RC4 or RC4_128 when the database is in compatibility level 90 or 100. (Not recommended.) Use a newer algorithm such as one of the AES algorithms instead. In SQL Server 2012 (11.x) and higher, material encrypted using RC4 or RC4_128 can be decrypted in any compatibility level.

Permissions

The visibility of the metadata in catalog views is limited to securables that a user either owns, or on which the user was granted some permission. For more information, see Metadata Visibility Configuration.
