SharePoint 2010: Rename the SharePoint State Service Database

Continuing on a quest to rename everything in SharePoint. You can find the first article here.

Rename the SharePoint State Service Database

The State Service in SharePoint 2010 is a service application that manages user state across browser requests. The SharePoint State Service is required by InfoPath Forms Services, the Chart Web Part, and certain Visio 2010 scenarios. You can find the State Service in Central Admin under Application Management – Manage Service Applications. There will be one or more State Service applications and associated proxies.

As usual, if the state service was created by the SharePoint Configuration Wizard, or you create it without editing the database name, the database will be created with a GUID on the end, such as:

StateService_5536604e93df4369a916cf408e0c3866  (ew!)

So let’s check out our state service in PowerShell. Open the SharePoint 2010 Management Shell (Start –> All Programs –> Microsoft SharePoint 2010 Products –> SharePoint 2010 Management Shell). To start, try a simple:

Get-SPDatabase | Select Name

This will list the SharePoint databases, and you should easily spot your State Service database. If for some reason you don’t know the name of the State Service Database, you can list all state service databases with this command:

Get-SPDatabase | Where-Object { $_.Type -eq "Microsoft.Office.Server.Administration.StateDatabase" }

Every SharePoint object has an ID (a GUID), and the easiest way to get a reference to a SharePoint object is by using that ID. You can get the ID for databases with this command:

Get-SPDatabase | SELECT Name, ID

Once you find the ID for your State Service Database, you can get a handle on it with this command:

$db=Get-SPDatabase -id {guid}

Next (and this is a common step with SharePoint Service databases; the trick is always figuring out how) you have to dismount the database:

Dismount-SPStateServiceDatabase -Identity <DatabaseID>

For “DatabaseID” you can either paste in the GUID we copied earlier, or you can use the $db variable as a hook to the database itself. $db.Id won’t work unless you cast it to a string first.

You’ll be asked to verify that you want to do this:

Confirm
Are you sure you want to perform this action?
Performing operation "Dismount-SPStateServiceDatabase" on Target "SP_Dev_StateService_DB".
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help
(default is "Y"):

A simple “Y” and enter will dismount the database. Now you can go to SSMS to rename the database — right-click on the database and select “Rename” or in T-SQL:

ALTER DATABASE oldName MODIFY NAME = newName

After you’ve renamed the database, then mount it again with the command

Mount-SPStateServiceDatabase -Name "<DatabaseName>" -DatabaseServer "<ServerName>"

And you’re all set.

If you completely screw up the database somehow, or feel it’s corrupted, there’s no critical data in the database – simply delete it and create a new one with the command:

New-SPStateServiceDatabase -Name "<StateServiceDatabase>" -ServiceApplication $serviceApp

Which will create a state service database and associate it with the State Service.
