  • Blog Post: Calling SQL Server from SharePoint Web-Part with Impersonation

    A question that comes up with fairly persistent regularity is “how come my web-part can’t connect to my SQL database/web-service/whatever with integrated credentials?”. It’s a question that has some rationale and some history behind it; the rationale being “I logged into the page as a user that should...
  • Blog Post: SharePoint 2013 on SQL Server AlwaysOn, 2014 Edition

    SQL Server 2014 is out bringing with it enhanced AlwaysOn clustering, and is indeed already supported by SharePoint 2013 past SP1. Some new benefits in SQL Server 2014 are the reliability improvements for when connectivity is lost between nodes and also the ability to add a SQL Server instance hosted...
  • Blog Post: Building True Multi-Subnet Windows Server Failover Clusters

    Something you may have heard of if you know clustering at all is the idea of “multi-subnet clusters”; a capability introduced in Windows Server 2012 (if memory serves) to Windows Failover Clustering. It’s conceptually the same thing as a normal cluster; it’s designed to withstand an instance failure...
  • Blog Post: Multi-subnet Clustered SQL + RegisterAllProvidersIP + SharePoint 2013

    Those of us that have even the most passing knowledge of SharePoint will know that it needs a SQL Server instance to work at all. If SQL goes down it takes SharePoint with it which is why it’s quite common to have SQL clustered to make sure SQL stays alive at all costs. I’ve covered this before already...

  • Blog Post: Patching SharePoint Farms with No Downtime

    Patching SharePoint farms is a rare occurrence but one that almost certainly will happen at some point or other, if only for the need to stay on a supported platform as time goes on. When patching SharePoint it’s necessary to take the entire farm offline at one point for reasons explained here...
  • Blog Post: Hot-Standby/Disaster-Recovery SharePoint Farms – Basic Setup & Failover

    Something that’s often required for high-availability SharePoint installations is the ability to failover to another web-farm entirely when needed because of a failure  of some kind on the 1st farm, or wanted because of maintenance taking the 1st farm offline completely. It’s simple enough in concept...
  • Blog Post: Set SharePoint Content Database in Read-Only Mode

    This a quick & easy one; I couldn’t find any MSFT material on how to do this as easily as I thought I might, hence this article. A simple question: how do you set a SharePoint content database to read-only? You may’ve seen the setting “Read-Only” in Central Administration and wondered “how do I make...
  • Blog Post: SharePoint 2013 and SQL Server AlwaysOn - High Availability SharePoint

    What is AlwaysOn and why use it for SharePoint? Update : SQL 2014 + SharePoint 2013 (abridged) guide also available . AlwaysOn is a great new feature to SQL Server 2012 that allows consuming clients to have a mirroring and failover database solution all transparently for a single named instance...
