Schedule SQL Jobs Using Azure Automation account

With the migration to SQL Azure happening on a fast pace i get lot of queries from my clients on how to schedule a SQL Agent job on a SQL Azure database In this Blog We will see how to schedule a SQL how to schedule a SQL Job using Azure Automation Account.


I am going to use my Test server 'Vinothtestsqlserver' and Test database 'VinothSampleDatabase' for this example.

Login into to Azure Subscription of the SQL Server and create new Automation Account from Azure MarketPlace

Once the Automation Account is created, Scroll through the left tab and select Runbooks under Process Automation,

First Step is to create a Credential for the SQL connection, Similar to Credential in SQL Agent or Data Sources in SSIS,  Under Shared Resources on you Automation Account Page, Select Credentials and Create a new Credential as below.

I have created a Credential Named BlogTestCredential for this example,

Now Create New Run book-This is similar to creating a new SQL agent Job

I have named the Runbook 'VinothTestRunBook' and Will be using Powershell Workflow. SQL Jobs can be created with either Powershell or Powershell Workflow.

Once the Runbook is created Your Script Editor will open, My aim for the SQL Job is to run 'SELECT * FROM sys.tables' from the VinothSampleDatabase every Hour.

I have used the below Powershell Script to achieve the output, The Script take Servername and Database as Parameter, then Uses BlogTestCredential using Get-Credential cmdlet to connect the SQL database. It then uses SQLConnection and SQLCommand Class to run the SQL.

In the Above Example I have used SQL Adapter to get the output and display, But in case you want to run a Store Proc or run Updates or Deletes use the Appropriate method(eg. ExecuteReader(), ExecuteNonQuery(), ExecuteScalar() etc.. More details on SQLCommand class and method in the below MSDN Link.


Once you Finish Scripting Test the Script by Clicking the Test Pane Button, where you can test the script by specifying the parameters(Server name and DB Name in this case) as below.

Once your testing Successful, Publish your run book by clicking the publish button this is same as creating a SQL Agent Job without a Schedule. 

Now once your Runbook is publish we can create a Schedule, Go back to Runbook Page on the Portal and select Schedules and create a new schedule as below I have created similar to SQL Agent job to run this script every hour,

Once you Create the Schedule Specify the Parameters for the Run book Schedule as below,

That's about it your job is now ready to run, To check the Job history Go to Workbook page in the Portal and click Jobs

Now you can see summary of a completed job, for detailed information click on the summary

And You can see the Jod Run's detailed info, To see the output click the output pane and you can see the job output.

There you go now you have perfectly working SQL Agent Environment in Azure. Powershell Workflow Allows you you run Steps in Parallel and in sequence we will see in detail on future blogs.

Replication - Compatibility issue

I was working on a POC concept for my client to test some replication functionality and got the below error,

"he selected subscriber does not satisfy the minimum version compatibility level"

I was using SQL Server 2008 as a distributor and Publisher and SQL Server 2012 as subscriber to mimic my client environment and i was using Developer edition to carry out my test.  I very well know the version and edition i was using supports replication. Finally after some research i found i was using SQL 2008R2 SSMS to set up my subscriber with was the cause of the mismatch, once i switched to SQL2012 SSMS everything was running fine. After this i did a testing with SQL 2012,SQL 2014 and SQL2016 similarly using publisher a one level below the subscriber and all the version failed with the same error when i use the lower version ssms. Hope the information helps.

Run SSMS As User in Different Domain

Every come across the trouble of having to login to a jump server in just to access SSMS since the server is in different domain. There is a way to by pass it and access SSMS using your second domain login from your desktop by using Runas /NetOnly option irrespective of domain trust.

Use the below command in the Command Prompt:-

runas /netonly /user:<domain\username> "<SSMSbasepath>\ssms.exe"

SSMS base path is the folder where your SSMS.exe is located.

Find SSAS instance Port Number

When you have more than one instance of SSAS installed in your Server you might end up in a situation to find the port numbers for each instance to set the firewall settings on the server. As you might all know the default Port for SSAS is TCP 2383, 

To find the port number of the other instances search for the msmdredir.ini file on your ProgramFiles(X86)->Microsoft SQL Server folder, most probably the file resides in the (%ProgramFiles(X86)%\Microsoft SQL Server\90\Shared\ASConfig\msmdredir.ini)location, Look in both 64 bit and 32 bit Program Files folder but more likely to be in 32 bit folder even for 64 bit installations.

If you have more than 1 Instance you will have entry in the ini file like below, If you change the port number to 0 it would take dynamic ports else you can assign a static port to the instance.



The Above exercise will hold good only for Non-Clustered SSAS instance, Clustered SSAS instance always uses TCP Port 2383 with the corresponding SSAS Cluster Resouce IP.
