Dear all,

I'm having a problem with configure Mirroring. When I use graphical inteface to config the Mirror, it is ok. But when using sql, there are an error that I can not understand.

Here is the code:

:SETVAR PrincipalServer DEMO\PARTNERA
:SETVAR MirrorServer DEMO\PARTNERB
:SETVAR WitnessServer DEMO\WITNESS
:SETVAR Database2Mirror AdventureWorksDW
go

:ON ERROR EXIT
go

:CONNECT $(PrincipalServer)

-- Mirroring ONLY supports the FULL Recovery Model
ALTER DATABASE $(Database2Mirror)
SET RECOVERY FULL
go

USE $(Database2Mirror)
go

CREATE ENDPOINT Mirroring
STATE=STARTED
AS TCP (LISTENER_PORT=5022)
FOR DATABASE_MIRRORING (ROLE=PARTNER)
GO

:CONNECT $(MirrorServer)

CREATE ENDPOINT Mirroring
STATE=STARTED
AS TCP (LISTENER_PORT=5023)
FOR DATABASE_MIRRORING (ROLE=PARTNER)
GO

:CONNECT $(WitnessServer)

CREATE ENDPOINT Mirroring
STATE=STARTED
AS TCP (LISTENER_PORT=5024)
FOR DATABASE_MIRRORING (ROLE=WITNESS)
GO

:CONNECT $(PrincipalServer)

BACKUP DATABASE $(Database2Mirror)
TO DISK = 'C:\TechReady\$(Database2Mirror).bak'
WITH INIT
GO

:CONNECT $(MirrorServer)

DECLARE @InstanceName sql_variant,
@InstanceDir sql_variant,
@SQLDataRoot nvarchar(512),
@ExecStr nvarchar(max)

SELECT @InstanceName = ISNULL(SERVERPROPERTY('InstanceName'), 'MSSQLServer')

EXECUTE master.dbo.xp_regread 'HKEY_LOCAL_MACHINE',

@InstanceName, @InstanceDir OUTPUT

SELECT @ExecStr = 'EXECUTE master.dbo.xp_regread '
+ '''HKEY_LOCAL_MACHINE'', '
+ '''SOFTWARE\Microsoft\Microsoft SQL Server\'
+ convert(varchar, @InstanceDir)
+ '\Setup'', ''SQLDataRoot'', @SQLDataRoot OUTPUT'

EXEC master.dbo.sp_executesql @ExecStr
, N'@SQLDataRoot nvarchar(512) OUTPUT'
, @SQLDataRoot OUTPUT

IF @SQLDataRoot IS NULL
BEGIN
RAISERROR ('Did not find the correct SQL Data Root Directory. Cannot proceed. Databases backed up but not yet restored.', 16, -1)
END

UPDATE #BackupFileList

+ REVERSE(SUBSTRING(REVERSE(PhysicalName)
, 1, PATINDEX('%\%', REVERSE(PhysicalName)) -1))

DECLARE @LogicalName sysname
, @PhysicalName sysname

DECLARE FileListCursor CURSOR FAST_FORWARD FOR
SELECT LogicalName, PhysicalName
FROM #BackupFileList

OPEN FileListCursor

FETCH NEXT FROM FileListCursor INTO @LogicalName, @PhysicalName

SELECT @ExecStr = N'RESTORE DATABASE $(Database2Mirror)' +
N' FROM DISK = ''c:\TechReady\$(Database2Mirror).bak''' +

END

-- NORECOVERY is required for Database Mirroring, replace is not.
-- Replace is used here solely to allow repetitive use of this script.
SELECT @ExecStr = @ExecStr + N' , NORECOVERY, REPLACE'

-- Useful for testing
-- Only return the string and then comment out the EXEC line below.
-- SELECT @ExecStr

EXEC (@ExecStr)

DEALLOCATE FileListCursor
GO

:CONNECT $(PrincipalServer)
SELECT DATABASEPROPERTYEX(N'$(Database2Mirror)', N'Status') -- Returns ONLINE
SELECT db_name(sd.[database_id]) AS [Database Name],

FROM sys.database_mirroring AS sd
WHERE sd.[database_id] = db_id(N'$(Database2Mirror)')
go

:CONNECT $(MirrorServer)

ALTER DATABASE $(Database2Mirror)
SET PARTNER = 'TCP://DEMO:5023'
-- SET PARTNER = 'TCP://Server.fully.qualified.dns.name:5091'
-- SET PARTNER = 'TCP://SQLIDW15HA.redmond.corp.microsoft.com:5091'
GO

:CONNECT $(PrincipalServer)

ALTER DATABASE $(Database2Mirror)
SET PARTNER = 'TCP://DEMO:5022'
-- SET PARTNER = 'TCP://Server.fully.qualified.dns.name:5092'
-- SET PARTNER = 'TCP://SQLIDW15HA.redmond.corp.microsoft.com:5092'
GO

ALTER DATABASE $(Database2Mirror)
SET WITNESS = 'TCP://DEMO:5024'
-- SET WITNESS = 'TCP://Server.fully.qualified.dns.name:5090'
-- SET WITNESS = 'TCP://SQLIDW15HA.redmond.corp.microsoft.com:5090'
GO

SELECT db_name(sd.[database_id]) AS [Database Name],
sd.mirroring_guid,
sd.mirroring_state,
sd.mirroring_state_desc,
sd.mirroring_partner_name,
sd.mirroring_witness_name,
sd.mirroring_witness_state,
sd.mirroring_witness_state_desc,
sd.mirroring_role,
sd.mirroring_role_desc,
sd.mirroring_role_sequence,
sd.mirroring_safety_level,
sd.mirroring_safety_level_desc,
sd.mirroring_safety_sequence,
sd.mirroring_failover_lsn
FROM sys.database_mirroring AS sd
WHERE sd.[database_id] = db_id(N'$(Database2Mirror)')

and the log is:

Msg 1452, Level 16, State 6, Line 3
The partner server instance name must be distinct from the server instance that manages the database. The ALTER DATABASE SET PARTNER command failed.
** An error was encountered during execution of batch. Exiting.

I Think the error is begin at:

ALTER DATABASE $(Database2Mirror)
SET PARTNER = 'TCP://DEMO:5023'
-- SET PARTNER = 'TCP://Server.fully.qualified.dns.name:5091'
-- SET PARTNER = 'TCP://SQLIDW15HA.redmond.corp.microsoft.com:5091'
GO

:CONNECT $(PrincipalServer)

ALTER DATABASE $(Database2Mirror)
SET PARTNER = 'TCP://DEMO:5022'
-- SET PARTNER = 'TCP://Server.fully.qualified.dns.name:5092'
-- SET PARTNER = 'TCP://SQLIDW15HA.redmond.corp.microsoft.com:5092'
GO

ALTER DATABASE $(Database2Mirror)
SET WITNESS = 'TCP://DEMO:5024'
-- SET WITNESS = 'TCP://Server.fully.qualified.dns.name:5090'
-- SET WITNESS = 'TCP://SQLIDW15HA.redmond.corp.microsoft.com:5090'
GO

but I can not find out the solution. Turn back to grafical interface, everything is done

Please help!
