Updating Microsoft AppFabric

Updating AppFabric

If you think that updating App Fabric is easy, you are very wrong!

It is not possible to update it just by running Cumulated Update for AppFabric, by doing this AppFabric Caching Service will be stopped and you cannot start it manually.

To update AppFabric, we must do the following:

1-???View the list of Distributed Cache servers by running the following command in SharePoint Management Shell:

Get-SPServiceInstance | ? {($_.service.tostring()) -eq "SPDistributedCacheService Name=AppFabricCachingService"} | select Server, Status        

2-???1- Enter the following path in the Registry Editor (regedit.exe):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

If the version is higher than 4.5.51209, right-click on the V4 folder and select Properties, and in the Security tab, change the Owner to the SPFarm user and click OK. Then we take Properties again and give Full Control access to the SPFarm user in the security tab.

For all its sub-folders, we give Full Control access to the SPFarm user and then change the Version to 4.5.51209 in all sub-folders.

3-???On one of the Distributed Cache Servers in SharePoint Management Shell, we type the following commands:

Stop-SPDistributedCacheServiceInstance –Graceful

Remove-SPDistributedCacheServiceInstance
        

4-????Check the list of Distributed Cache Servers with the following command:

Get-SPServiceInstance | ? {($_.service.tostring()) -eq "SPDistributedCacheService Name=AppFabricCachingService"} | select Server, Status        

5-????Now update AppFabric to the latest version manually. (e.g. AppFabric-KB3092423-x64-ENU.exe)

6-????After the update, we use the following commands to check the version:

(Get-ItemProperty “C:\Program Files\AppFabric 1.1 for Windows Server\PowershellModules\DistributedCacheConfiguration\Microsoft.ApplicationServer.Caching.Configuration.dll” -Name VersionInfo).VersionInfo.ProductVersion        

CU1: 1.0.4639

CU2: 1.0.4644

CU3: 1.0.4652.2

CU4: 1.0.4653.2

CU5: 1.0.4655.2

</appSettings>

9-????Run Service Instance with the following command in SharePoint Management Shell:

Add-SPDistributedCacheServiceInstance        

10- ?To ensure that the service is running, use the following command:

Get-SPServiceInstance | ? {($_.service.tostring()) -eq "SPDistributedCacheService Name=AppFabricCachingService"} | select Server, Status        

11- Make sure that Cache host is up and working with the following commands:
