SP2010 – Removing old Application Pools for Service Applications


You’re creating a new Service Application, and in the “use an existing application” pool drop-down menu you see listings for many application pools that don’t actually exist in IIS.

How this happened:

You probably created many Service Application Pools when creating old Service Applications that have since been deleted. After you told SharePoint to remove the Service Application, there was an unused Application Pool in IIS that you subsequently removed manually.

How to clean this up:

Open a PowerShell window that has the Microsoft.SharePoint.Powershell snap-in loaded, and use the Remove-SPServiceApplicationPool “APP POOL NAME” command to tell SharePoint that those old application pools no longer exist. The next time you try to create a new Service Application, those old nonexistent options will be gone.

SharePoint 2010: Service Packs and Site Collection Backups

This only applies to Site Collection backups, and not farm backups. Farm backups are apparently just fine as long as you run the psconfig update command afterward. I haven’t had to deal with these specifically yet, and if those have the same issue then I’ll post at a later date (when I come across those issues).

If you have a site collection backup from before a service pack was applied, you can not restore from that backup after the service pack. What you’ll want to do is to set aside another environment (even if it’s a virtual image) from before the update in case you need to restore one of these old backups in the future. After you have the content database restored with the site collection in it, you can attach to the new environment and run psconfig’s update to get it up to speed.

The pre-SP1 environment I stood up for this purpose was a Windows 7 developer install of just Foundation on no domain at all. The final destination was in a domain running server.

Yes, I just had to do this. Yes, it was a huge hassle. Yes, it worked.

Happy restoring!
