Database mirror disconnected issue

  • Hi Guys,

    I have question regarding database mirroring. I have active active cluster

    production server and stand alone dr server, which I setup 7 db mirroring

    from prod to dr server. The setup was good and it has been running for 2

    weeks. Today all db mirroring was gone. I got error like:

    Bypassing recovery for database 'codesample' because it is marked as an

    inaccessible database mirroring database. A problem exists with the mirroring

    session. The session either lacks a quorum or the communications links are

    broken because of problems with links, endpoint configuration, or permissions

    (for the server account or security certificate). To gain access to the

    database, figure out what has changed in the session configuration and undo

    the change.

    and other error like:

    Message

    Database mirroring connection error 4 'An error occurred while receiving

    data: '10054(An existing connection was forcibly closed by the remote

    host.)'.' for 'TCP://messagesv.net:5022'.

    Does any body familiar with this error? Thanks in advance.

  • Have you checked the logs on the both the Primary and the Mirror?

    Are you using DOMAIN or local account?

    Also it maybe worth going through the link below

  • Thank you. The error I posted in my last message was gotten from error log in mirroring server. It looks like the network had issue. It had been worked for 2 weeks, then was broken suddenly. I don't know why?
