  • Hello All,

    When i start configuring database mirroring on the principle server, Finally it show the error msg like this

    SQL Server cannot create the mirroring endpoint, 'Mirroring'.


    Create failed for Endpoint 'Mirroring'.  (Microsoft.SqlServer.Smo)

    For help, click:

    An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

    Database mirroring is disabled by default. Database mirroring is currently provided for evaluation purposes only and is not to be used in production environments. To enable database mirroring for evaluation purposes, use trace flag 1400 during startup. For more information about trace flags and startup options, see SQL Server Books Online. (Microsoft SQL Server, Error: 1498)

  •  SQL Server 2005 was first released for general availability, database mirroring was available only for evaluation purposes and had to be enabled via trace flag 1400. With SQL Server 2005 SP1, database mirroring became completely supported as a general feature, with no restrictions.

    if guess you are having RTM version on mirror server if so  than mirroring is disabled for sql server 2005 ! To enable use trace flag 1400 . 

    SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'),
    SERVERPROPERTY ('edition') 

    Thanks,Suhas V

  • Can you please cross check it once again ! i am cent percent sure this issue is with not enabling the trace flag 1400 either on mirror or principal 

    Goto RUN –> Type sqlservermanager.msc
    Right click on SQL Server(instancename) service and click on properties
    Click on Advanced tab
    In the startup parameters enter this ;-T1400 and click on OK
    Restart SQLservices and then try configuring db mirroring 


    Please let me know the O\P of DBCC tracestatus command on both principal and mirror server 
    Thanks,Suhas V

  • Enable trace 1400 on both principal and mirror instance and then start the SQL server .
    RTM version will not support mirroring without this trace flag else update SP3 for both your instances.

    Thanks, Leks

  • Enable trace -T1400 on both the Principal and Mirror server and restart SQL services. Else try with Service Pack 2 on your server. Once server is restarted check whether the Trace has been set correctly by clicking properties of SQL instance in SQL services.
