SQL Server maintenance via PowerShell

-
I was asked to help create a maintenance plan for a SQL server . I chose to implement the plan using PowerShell for the following reasons:  PowerShell is a procedural scripting language and the maintenance plan would have a few procedural steps and iterations through objects. PowerShell was also built on top of the .Net framework. This means I could make use of the SQL Shared Management Object (SMO) library within my script. SQL Server also has a SQL PowerShell provider , which is pre-loaded when you run SQLPS. Support also has been extended to SQL Server Agent as there is a native PowerShell, which uses SQLPS, job subsystem. I have been using PowerShell for a while and found it really useful; it allows you to solve problems, much more easily, than using the standard SQL tools. A copy of my script, and related scripts, are available from my SkyDrive using the following link: OneDrive The maintenance script, SQLServerMaintanceTask.PS1 , does the following, depending o...

Challenges of move SQL Server data to Microsoft Azure SQL Server PaaS

This post covers one of the challenges we face when moving our infrastructure from on-prem to Microsoft Azure: Moving SQL Server data from on-premise to Microsoft SQL Server Paas. Moving our data was a challenge for the following reasons: Our company has tight controls and rules about what software/connectivity is allowed on our network The database that we need to migrate after compression was over 100GB in size. No information about how long other migration processes would take. As needed to ensure our migration was complete before the next Monday on the weekend of our migration. For most people migrating their data, the best option is to use Azure Database Migration Service , especially when transferring a database size that we were. We couldn't use the Azure Database Migration Service for the following reasons: Azure Database Migration Service requires software installed on a server within our network Connections to both databases ...

As mention in a previous post, we are using Azure SQL Server IaaS to help our transition to the cloud. The main reason for this is how some of our SSIS projects, which we inherited, were created. Some were using SSIS to manage the transactions, which uses MSDTC not supported in Azure. Use extra .Net libraries to read JSON and office files; external programs to do file operations like decompression. Migration timelines and priorities we didn't have time to refactor these projects. While ago we started to deploy our SSIS projects to our Azure SQL Server IaaS virtual machine, a Windows 2019 server with SQL Server 2019, to get the following error: SSIS Deployment Error 6522 "A required privilege is not held by the client". We able to resolve our problem by using the steps we found in the following blog posts: System.ComponentModel.Win32Exception: A required privilege is not held by the client while Deploying SSIS Project | Microsoft Docs . Fixing SQL 2012 SSIS Deployment Err...
