Database Mirroring

  • Dear All,

    I know it's trival doubt !!!

    Can someone shed light on the below? please

    After mirroring configuration done, If we create an index on Principal database , will it present on Mirror database? please

    If we perform index rebuilding at Principal database, what will happen ? I mean, will it effect to Mirror database or need to do when mirror becomes principal?

    Thanks and Regards,

    Ravichandra.

  • yes and yes and it 'll be ok.

    mirroring works with log replication, so everything you do on your principal db will also be performed on your mirror db as long as you don't break mirroring.

    Depending on the type of mirroring you configured, you may lose some data at the mirror db because of async settings.
