Issue while deleting web application or service application in SP 2010

I came across an error while deleting a User Profile Service Application and it mentioned "An update conflict has occurred, and you must re-try this action. The object UserProfileApplication Name=User Profile Service Application was updated by [farm admin id], in the OWSTIMER (ID) process, on machine [machine name]. View the tracing log for more information about the conflict."

Below are the steps I followed to remove the User Profile Service Application with out error.
On the server throwing the OWSTIMER (ID) error I cleared the server cache, by following the below steps -
1. Logged into server throwing the OWSTIMER error.
2. Went to Start -> Administrative Tools -> Services
3. Stopped the Timer service by Right click SharePoint 2010 Timer and click Stop

Next I cleared the Server Cache (Win 2008 x64 R2) by following the below steps-

1. Browsed to local drive (c:) on the server
2. Looked for the ProgramData directory.  It is set to be hidden by default. Hit the Alt key -> Tools -> Folder Options -> View and under Hidden Files and folders click the Show Hidden files and folders radio button. Click ok.
3. Next browsed to ProgramData/Microsoft/SharePoint/Config directory
4. Inside this directory there are a couple folders with [GUIDs] as their names. Looked inside each folder until I found the one that has all the .XML documents and the Cache.ini file.
5. Backuped the Cache.ini file and save it in a safe place.
6. Then highlighted all the .XML files and deleted them.
7. Opened up the Cache.ini file and deleted the value inside and replaced it with 1. Saved a close the file.
8.  Went back to Administrative Tools -> Services, right clicked SharePoint 2010 Timer services and clicked Start to restart the services.

Inside the ProgramData/Microsoft/SharePoint/Config directory inside the [GUID] folder that had all the .XML documents and Cache.ini files all the .XML documents that were deleted were starting to repopulate.

Retrying the deletion went through with no error.
 

List of Active Sharepoint databases in SharePoint 2010

There was a need when I had to get the list of sharepoint databases present on a shared SQL server instance.

Below PowerShell Command helps to reduce the work in searching the databases individually. We need to go to the Sharepoint Management Shell and run the below powershell command -

Get-SPDatabase | Select Name | Out-File c:\AllActiveSPDBs.txt

The text file will be created automatically if it doesn't exist.

Also you can go and validate the same from Central Administration as well by following the path
Central Administration --> Upgrade and Migration --> Review Database Status
