Distributed Cache (DC) is one of the new components that is added in SharePoint. It plays an important role in the SharePoint server because this is a key component for performance and caching.
This Distributed cache is not a SharePoint service but a standalone service called AppFabric 1.1 for Windows servers. This is known as one of the dangerous parts of SharePoint in terms of social computing. Though it may not cause an issue while managing Distributed Cache in SharePoint because it is quite comfortable using PowerShell and this is also applied for the same when repairing.
However, in SharePoint 2016 many users complained they are getting the Distributed Cache Error, so below have a look what this error and how to fix Distributed Cache Error in SharePoint?
Issue:
When MinRole SharePoint 2016 server is set up with 9 SharePoint servers then one Distributed cache server does not behave properly and it gives the error “cacheHosInfo is null”. Even it is said that “Distributed cache host may have caused the cache reliability problems”.
However, there are multiple servers farm and so Distributed cache can run only 1 server in the farm. But actually when the use-CacheCluster command is run on one of the SharePoint servers then the below-mentioned error is received.
Use-CacheCluster : ErrorCode<ERRPS001>:SubStatus<ES0001>:Error in reading
Causes:
Well, the cause of this error states that the server is not able to read and get the values of the connection string. However, the information is from AppFabric and when the Distributed Cache service is not running on the server then make sure it is because of the error as the server is not able to communicate to AppFabric.
Well to check where the Distributed cache is running on which server, some process can be done.
PowerShell
In SharePoint, open PowerShell and then run the below-mentioned command:
After running the above command, only one server is returned where DC is running and the problem is seen.
How to Fix Distributed Cache Error in SharePoint?
Well, everything is in front as expected but when you want to access the Distributed cache from all servers in the farm so you have to allow the provision of the DC instance on every server in the farm. Here some of the ways to fix the Distributed Cache error.
Solution 1: Use PowerShell
Now nothing to be done except leaving it. If you want to run this command then you have to log in on the server where the Distributed cache is running and then run it.
- After that login to the server where you have allowed the DC
- Now open PowerShell and then run the below command:
Use-CacheCluster
Get-CacheHost
Solution 2: Install Distributed Cache
Now install the Distributed cache instance on a server in the farm and then stop it, though it may look some odd type it works. After that run, the below mentioned command on the server where you have to run the DC.
add-SPDistributedCacheServiceInstance
Following the above command successfully supplies Distributed Cache service instance on the server and after that start the service and again run the below-mentioned command:
stop-SPDistributedCacheServiceInstance -Graceful
Following the command will only stop the DC on the server but will not remove it. Now when you run:
Use-CacheCluster
Get-CacheHost
Now as you can see the DC is up on the server where you run it and down on the server that you want it. Now check if the Distributed Cache error in SharePoint is fixed or not.
