Database mirrioring Error (Microsoft SQL Server, Error: 1418)

  • See if this helps you

    http://msdn.microsoft.com/en-us/library/aa337361.aspx

  • You have to create TCP endpoints on Primary and on Mirror server and then you have to grant connect permission on both servers.

  • Guys,

    The error is misleading while the solution is pretty simple and straight..

    Server A --> principal --> domain\Servic_Account1

    Server B --> Mirror --> domain\Servic_Account2

    Make sure domain\Servic_Account1 has sysadmin rights on Server B

    and the same way domain\Servic_Account2 has sysadmin rights on Server A.

    Set up the mirroring again and you should be good with out any errors.

  • We have did that still unable to start the mirror in the server.Check the attached screenshot.

  • An Error occured while starting Mirroring.

    Additional information:

    Alter failed for Database 'testbest_DB'.(Microsoft.Sqlserver.Smo)

    An Exception occured while executing a Transact-SQL staement or Batch.(Microsoft.SqlServer.ConnectionInfo)

    The server network address "TCP:dbserver1:5022" can not be reached or does not exist.Check the network addess name and that the ports for local and remove endpoints are operatioanal

    I am getting this error while star mirroring,

  • 1) Run SQL services and SQl Agent with Same Account on Both server.

    2) Check Telnet is working on same port.

    3) Try to keep ldf and mdf path same drive for both server.

    Any Issue Let me know.

  • Configure SQl mirror with following reference....
