SQL Server 2008 R2 SP1 Questions and Observations

  • I am in the process of applying SS2K8R2 SP1 on some test servers and low profile live servers and I have observed different results depending on the server. So, the following are some questions I have regarding deployment.

    1. In a mirror environment, should the service pack be deployed to the partner or the principle first?

    2. In a replication environment, the the service pack be deployed to the subscriber or publisher first?

    3. Can this be deployed on a production server without users experiencing a service outage?

    Thanks.

  • Okay, I notice I'm getting reads, but no replies.

    Basically I already know the answer to number three, because I watched the services restart when I performed the upgrade on the test mirror environment. But the mirror partner is the only server out of the three servers I ran sp1 on that actually required a restart, which I found curious.

    The reason I ask questions one and two is because I don't know if upgrading two databases (the mirror principle and the replication publisher) that will then be pushing data to what would then be a lesser version, my cause corruption. It seemed like a good question to me.

    1. In a mirror environment, should the service pack be deployed to the partner or the principle first?

    I've never patched a mirrored server but the same process applies as did in SQL 2005 and the detail is found on the link below

    2. In a replication environment, the the service pack be deployed to the subscriber or publisher first?

    There are a few references for this but the order it should be applied is distributor, publisher and subscriber. Obviously, you may have a publisher/distributor which shortens the sequence.

    I hope this helps. 😀

  • Thanks. Yes it does help.
