I wrote a blog earlier about my first experience (and error encountered) with “Stretch Database” feature. In this blog I would talk about the error – Free Trial subscriptions can provision Basic, Standard S0 through S3 databases, up to 100 eDTU Basic or Standard elastic pools and DW100 through DW400 data warehouses.
One of my blog readers read my earlier blog SQL SERVER – Stretch Database – ERROR: The Provided Location is Not Available for Resource Group.
He followed the wizard, but it failed with an error. He sent me an email and I asked for a complete log which was generated and here is what we see.
- [Informational] TaskUpdates: Message:Task : ‘Configure Stretch on the Database StretchTestDB’ — Status : ‘Running’ — Details : ‘Task failed due to following error: Microsoft.SqlServer.Management.Smo.FailedOperationException: Alter failed for Database ‘StretchTestDB’. —> Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch. —> System.Data.SqlClient.SqlException: ‘Free Trial subscriptions can provision Basic, Standard S0 through S3 databases, up to 100 eDTU Basic or Standard elastic pools and DW100 through DW400 data warehouses’
- ALTER DATABASE statement failed.
The error message gives and hints that the reader was using “Free” subscription which doesn’t have the capability to consume Database Stretch Unit (DSU). Here is what I see in my management studio.
Below is the screenshot from the portal.
As per error message below service tiers are possible.
- Basic, Standard S0 through S3 databases.
- Up to 100 eDTU Basic or Standard elastic pools
- DW100 through DW400 data warehouses
And none of them talk about DSU and hence the error. So, I replied to my reader that he needs a paid subscription to use this feature. I am surprised that Microsoft has not documented it, or at least I am not able to search it. If you find it, please share it via comments.
