Content databases contain orphaned Apps

SharePoint Health Analyzer rule “Content databases contain orphaned Apps.”

Some situation content database may become corrupted. The corrupted database may contain orphaned apps. Orphaned apps are not accessible, which causes unnecessary resource and license consumption and may result in failures in SharePoint upgrade.

Solution

Remove app for SharePoint instances from a SharePoint 2013 site.

A user must have the Manage Web site permission to remove an app for SharePoint. By default, this permission is only available to users with the Full Control permission level or who are in the site Owners group.

To remove an app from a SharePoint site

  • Verify that the user account that is performing this procedure is a member of the Site owners group.
  • On the site, on the Settings menu, click View Site Contents.
  • In the Apps section, point to the app that you want to remove, click “…”, and then click Remove.
  • Click OK to confirm that you want to remove the app.

To remove an app by using Windows PowerShell

Verify that you have the following memberships:

  • securityadmin fixed server role on the SQL Server instance.
  • db_owner fixed database role on all databases that are to be updated.
  • Administrators group on the server on which you are running the Windows PowerShell cmdlets.
  • Site Owners group on the site collection to which you want to install the app.

An administrator can use the Add-SPShellAdmin cmdlet to grant permissions to use SharePoint 15 Products cmdlets. On the Start screen, click SharePoint 2013 Management Shell, type the following commands, and press ENTER after each one:

$instances = Get-SPAppInstance -Web
#Gets all apps installed to the subsite you specify.

$instance = $instances | where {$_.Title -eq ”}
#Sets the $instance variable to the app with the title you supply.

Uninstall-SPAppInstance -Identity $instance
#Uninstalls the app from the subsite.

At the question “Are you sure you want to perform this action?”,
type Y to uninstall the app.

Locate and remove app instances in all locations

An app for SharePoint in the App Catalog is available for users to install.Users can install apps for SharePoint on many sites. Below two Windows PowerShell scripts can be used to find all locations for a specific app and then uninstall all instances from every location.

First script to locate all instances of a specific app in a SharePoint environment. Then use the second script to uninstall all instances of the app from the SharePoint environment.

To locate specific apps by using Windows PowerShell (save as script and run script)

Verify that you have the following memberships:

  • securityadmin fixed server role on the SQL Server instance.
  • db_owner fixed database role on all databases that are to be updated.
  • Administrators group on the server on which you are running Windows PowerShell cmdlets.

An administrator can use the Add-SPShellAdmin cmdlet to grant permissions to use SharePoint 2013 cmdlets

save the below script as “Get-AppInstances.ps1”

This Windows PowerShell script gets all app instances from your SharePoint 2013 farm for a specified App ID on a specified web application. You specify the App ID and the web application URL and the script will remove all of the instances of the App for all webs in that web application.

param(
[Parameter(Mandatory=$true)] [Guid] $productId,
[Parameter(Mandatory=$true)] [String] $webAppUrl
)

function GetAllInstances($productId = $null, $webAppUrl = $null)
{
$outAppName = "";
$sites = Get-SPSite -WebApplication $webAppUrl
$outWebs = @()
foreach($site in $sites){
if($site.AdministrationSiteType -ne "None"){
continue;
}
$webs = Get-SPWeb -site $site
foreach($web in $webs) {
$appinstances = Get-SPAppInstance -Web $web
foreach($instance in $appinstances) {
if($productId -eq $instance.App.ProductId) {
if ($outAppName -eq "") {
$outAppName = $instance.Title;
}
$outWebs += $web;
}
}
}
}
return ($outAppName,$outWebs)
}
Write-Host "This script will search all the sites in the webAppUrl for installed instances of the App."
$confirm = Read-Host "This can take a while. Proceed? (y/n)"
if($confirm -ne "y"){
Exit
}

$global:appName = $null;
$global:webs = $null;

{
$returnvalue = GetAllInstances -productId $productId -webAppUrl $webAppUrl;
$global:appName = $returnvalue[0];
$global:webs = $returnvalue[1];
}
);

$count = $global:webs.Count;
if($count -gt 0){
Write-Host "App Name:" $global:appName;
Write-Host "Product Id: $productId";
Write-Host "Number of instances: $count";
Write-Host "";
Write-Host "Urls:";

foreach($web in $global:webs) {
Write-Host $web.Url;
}
}
else {
Write-Host "No instances of the App with Product Id $productId found.";
}
return;
  • Now Open “SharePoint 2013 Management Shell”
  • Change to the directory where you saved the file.
  • At the Windows PowerShell command prompt, type the following command: 
./ Get-AppInstances.ps1 -productId -webAppUrl

To uninstall specific apps from all locations by using Windows PowerShell (save as script and run script)

Verify that you have the following memberships :

  • securityadmin fixed server role on the SQL Server instance.
  • db_owner fixed database role on all databases that are to be updated.
