database mirroring

  • Hi,

    I followed a document to do database mirroring in two server.Server A have two instances .I made one as principal and another one as witness.Server B have one instance I made that as mirror and followed the following steps.

    But i got again the error 1418, the server network address cannot be reached or does not exist.Can anybody help me for this error??

    Editor's Note: Section quoted from book removed.

  • A quick read through the (overly-long) notes tells me that you are trying to create ALL the endpoints on TCP/4040.

    That is fine if each MSSQL Instance is on a separate server. But you have one server with two instances. You will have to change the Port number for one of the endpoints.

  • If I may suggest - remove the extract from a wrox book as it is probably (at best) borderline copyright infringement - posting copyrighted works on a public forum.

  • Perhaps you could be a little more specific? What, exactly, is not working? What steps have you taken to figure out what is wrong?

    Is the long copy-and-paste document from a Wrox book, or any other copyrighted source? If yes, I second the GilaMonster and strongly suggest you remove it. If nothing else, it is overly long and largely irrelevant.

  • I looks that this post text is just a copy/paste from some book chapter which is the voilation of copyrights can you please tell what actually is not working.

  • I had a similar problem that ended up being a DNS entry problem. As a test, you can change the server name the endpoint is pointing to and use the IP instead. If this works, you hae a DNS problem.

  • ping the server with hostname.

    if not put an entry in host file and try to connect that server through osql
