SQL Server “Failed to open loopback connection”

TLDR: If you have the SQL Browser Service disabled then you must also have Shared Memory enabled, otherwise SQL Server can’t communicate with itself. While setting up a sandbox Always On Availability Group cluster recently I ran into some unexpected behavior. The first sign of problems was that SQL Agent would not start. The service… Continue reading SQL Server “Failed to open loopback connection”

Installing SQL Server Using Desired State Configuration

(Update: I’ve since discovered that SqlServerDsc has replaced xSQLServer.) One of my growing passions is using PowerShell Desired State Configuration (DSC) to automate all the things. I started out with simple configurations for testing but wanted to dive into more complex\useful situations for my day-to-day DBA life. To be honest, I was intimidated by the… Continue reading Installing SQL Server Using Desired State Configuration

Dynamics CRM Install\Import “The SQL Server {sqlserver_name} is unavailable”

My apologies for the significant gap between my last post on our CRM 2016 Upgrade Adventure and this one. My time has been consumed with preparing for go-live, but I’ve been keeping track of the roadblocks and caveats we encounter as I go so that I can post about them at later dates. One of… Continue reading Dynamics CRM Install\Import “The SQL Server {sqlserver_name} is unavailable”

Dynamics CRM Import Fails on “Upgrade Indexes”

As I mentioned in the last post, I’m taking you through our adventure in upgrading the existing on-premise Dynamics CRM 2011 environment to 2016 (and eventually 2016 cloud). Previously I discussed the first show-stopper error we received, “Must declare the scalar variable “@table”.” Following that resolution the import continued past the stage “Metadata xml upgrade: pass… Continue reading Dynamics CRM Import Fails on “Upgrade Indexes”

Dynamics CRM Import Error “Must declare the scalar variable “@table”

This post is the first in a new series I’m going to call “CRM 2016 Upgrade Adventure”. Summary: my organization has taken on the ambitious challenge of not only upgrading our existing Dynamics CRM 2011 environment to the 2016 version but  of moving it to the cloud service as well. Aside from getting the vanilla components… Continue reading Dynamics CRM Import Error “Must declare the scalar variable “@table”

Using Powershell to Refresh a Test SQL Server Instance from Production

A project I’ve been wanting to work on for a long time is how to automate restores of our Production databases to the Test instance. There are a number of challenges associated with this. First, the restore has to be able to find which backup it needs to use. Secondly, many of our databases do… Continue reading Using Powershell to Refresh a Test SQL Server Instance from Production

Using PowerShell to Perform Availability Group Failovers

In the past we’ve explored how to use PowerShell to automate failovers on SQL Failover Clusters for Windows Updates and other scheduled maintenance. But what if you’re using Availability Groups instead of the traditional cluster? Fear not, there is still a PowerShell option for that. Usually I would have our night team use SSMS to fail… Continue reading Using PowerShell to Perform Availability Group Failovers

Using PowerShell to Execute SQL Maintenance

It’s an odd truth that laziness leads to better systems administration. That is, so long as it spurs you to automate and thoroughly document a repetitive or tedious task. For instance, I was recently tasked with reducing the excessive size of some system tables in our Microsoft Dynamics CRM environment. To start with, I accomplished… Continue reading Using PowerShell to Execute SQL Maintenance
