Database Mirroring Error

  • Hi All,

    I have the Principle ,Mirror and Wintness server (i my case on same server) with different Instance .At the time of installing i have no errors.I have issue when i try to enable the Start Mirroring option.

    I am propmted with

    "TCP://instance name.Domin.com:5022" cannot be reached or does not exist.Check the network address name and that the ports for the local and remote endpoints are operational.

    I checked the firewalls all eneabled..And the TCP/IP enabled in SQL Configuration .Not sure what the issue is..

    Can some one help on this issue.

    Many Thanks in Advance

  • "TCP://instance name.Domin.com:5022" cannot be reached or does not exist.Check the network address name and that the ports for the local and remote endpoints are operational.

    Since you have all the roles on a single server you would need different port numbers for each mirroring endpoint. The configuration would look something like this.

    server1\instance1 : tcp://server1.mydomain.com:5022

    server1\instance2 : tcp://server1.mydomain.com:5023

    server1\instance3 : tcp://server1.mydomain.com:5024

  • Hi Todd,

    I had just forgotten to Add that information the i have 3 Different Ports for each 3 Instance.

    But Still no luck

  • Did you check if the mirroring endpoints were started? The default sate when using CREATE ENDPOINT is stopped.

  • Yes. I had checked that it was in Started State.
