SCCM 2012 R2 Branch Cache - Distributed Cache mode

Hello to all, I understood the process to enabled Branch Cache - Distributed Cache mode in source server and how to enable clients to use it. Fine. I saw a text that states "
BranchCache management is integrated in the Configuration Manager console. For applications, you can configure BranchCache on a deployment type. For programs and software updates, you can configure the BranchCache settings on the deployment.
Does it mean that I also need to configure Branch Chache individually for applications, programs and updates so they can take advantage of it? If positive, how to do this "specific" configuration?
Regards, EEOC.

The BranchCache option is checked by default, so you would only need to disable it for any deployments where you didn't want this functionality.
You can't enable BranchCache for Task Sequences though - but we have a script for that :-)

SCCM 2012 – Client Installation properties - client cache size

Hi,
I'm setting the command line options for the client push install and taking into account the default client cache size is 5120MB. But my concern is a lot our servers and some workstations don't have enough free disk space for this.
So I was going to set the cache size to only use a certain percentage, say 10% for example:
SMSSITECODE=xxx SMSCACHEFLAGS=PERCENTDISKSPACE;NTFSONLY SMSCACHESIZE=10 SMSMP=FQDN-MP FSP=FQDN-FSP
So does it allocate 10% of the total hard disk size or 10% of the free disk space available?
Thanks

As Torsten noted, this isn't an allocation or reservation of disk space. It's a maximum size that the ConfigMgr agent will allow the cache to grow to. If the servers don't have enough free space, the ConfigMgr agent won't stop or block or cause any
failures until it actually needs to use that space.
However, if you honestly have servers and workstations that don't have 5GB of free disk space, you've got much, much bigger problems.

Distributed Cache Mode With W2k8 Enterprise ServerCore ???

Hi, can someone teach me how to configure BranchCache in Distributed Cache Mode with W2k8 Enterprise ServerCore? tks a lot!

Hi,
Since Server Core installation provides a minimal environment for running specific server roles, which reduces the maintenance and management requirements and the attack surface for those server
roles, so the installation process of BranchCache Distributed Cache Mode is the same as the Windows Server 2008 with GUI. Since there isn’t any official document about this, I suggest we could use the following guides as reference.
BranchCache Distributed Cache Mode Step by Step Guide
http://www.microsoft.com/en-us/download/details.aspx?id=5772
Here are some articles about how to configure a Server Core installation, they may be useful to us.

Hi,
There are numerous ways to change the cache size.
You could deploy a vbscript to a collection of the devices.
On Error Resume Next
Dim UIResManager
Dim Cache
Dim CacheSize
CacheSize=20000
Set UIResManager = createobject("UIResource.UIResourceMgr")
Set Cache=UIResManager.GetCacheInfo()
Cache.TotalSize=CacheSize
Or you could use a configuration item.
http://blog.coretech.dk/heh/configuration-items-and-baselines-using-scripts-powershell-example/
You can also use the right click tools by Now Micro on a collection, if all the servers are on this would be the easiest / quickest way.

How can i configure Distributed cache servers and front-end servers for Streamlined topology in share point 2013??

my question is regarding SharePoint 2013 Farm topology. if i want go with Streamlined topology and having (2 distribute cache and Rm servers+ 2 front-end servers+ 2 batch-processing servers+ cluster sql server) then how distributed servers will
be connecting to front end servers? Can i use windows 2012 NLB feature? if i use NLB and then do i need to install NLB to all distributed servers and front-end servers and split-out services? What will be the configuration regarding my scenario.
Thanks in Advanced!

For the Distributed Cache servers, you simply make them farm members (like any other SharePoint servers) and turn on the Distributed Cache service (while making sure it is disabled on all other farm members). Then, validate no other services (except for
the Foundation Web service due to ease of solution management) is enabled on the DC servers and no end user requests or crawl requests are being routed to the DC servers. You do not need/use NLB for DC.

Newsfeed error - The operation failed because the server could not access the distributed cache.

Recently installed SharePoint 2013 RTM, on the newsfeed page an error is displayed, and no entries display in the following or everyone tabs.
"The operation failed because the server could not access the distributed cache."
Reading through various posts, I've checked:
- Activity feeds and mentions tabs are working as expected.
- User Profile Service is operational and syncing as expected
- Search is operational and indexing as expected
- The farm was installed based on the autospinstaller scripts.
- Don't believe this to be a permissions issue, during testing added accounts to the admin group to verify
Any suggestions are welcomed, thanks.
The full error message and trace logs is as follows.

Distributed Cache service stuck in Starting Provisioning

Hello,
I'm having problem with starting/stopping Distributed Cache service in one of the SharePoint 2013 farm servers. Initially, Distributed Cache was enabled in all the farm servers by default and it was running as a cluster. I wanted to remove it from all hosts
but one (APP server) using below PowerShell commands, which worked fine.
Stop-SPDistributedCacheServiceInstance -Graceful
Remove-SPDistributedCacheServiceInstance
But later I attempted to add the service back to two hosts (WFE servers) using below command and unfortunately one of them got stuck in the process. When I look at the Services on Server from Central Admin, the status says "Starting".
Add-SPDistributedCacheServiceInstance
Also, when I execute below script, the status says "Provisioning".
Get-SPServiceInstance | ? {($_.service.tostring()) -eq "SPDistributedCacheService Name=AppFabricCachingService"} | select Server, Status
I get "cacheHostInfo is null" error when I use "Stop-SPDistributedCacheServiceInstance -Graceful".
I tried below script,
$instanceName ="SPDistributedCacheService Name=AppFabricCachingService"
$serviceInstance = Get-SPServiceInstance | ? {($_.service.tostring()) -eq $instanceName -and ($_.server.name) -eq $env:computername}
$serviceInstance.Unprovision()
$serviceInstance.Delete()
,but it didn't work either, and I got below error.
"SPDistributedCacheServiceInstance", could not be deleted because other objects depend on it. Update all of these dependants to point to null or
different objects and retry this operation. The dependant objects are as follows:
SPServiceInstanceJobDefinition Name=job-service-instance-{GUID}
Has anyone come across this issue? I would appreciate any help.
Thanks!

Hi ,
Are you able to ping the server that is already running Distributed Cache on this server? For example:
ping WFE01
As you are using more than one cache host in your server farm, you must configure the first cache host running the Distributed Cache service to allow Inbound ICMP (ICMPv4) traffic through the firewall.If an administrator removes the first cache host from
the cluster which was configured to allow Inbound ICMP (ICMPv4) traffic through the firewall, you must configure the first server of the new cluster to allow Inbound ICMP (ICMPv4) traffic through the firewall.
You can create a rule to allow the incoming port.
For more information, you can refer to the blog:
http://habaneroconsulting.com/insights/Distributed-Cache-Needs-Ping#.U4_nmPm1a3A

Foundation 2013 Farm and Distributed Cache settings

We are on a 3 tier farm - 1 WFE + 1APP + 1SQL - have had many issues with AppFab and Dist Cache; and an additional issue with noderunner/Search Services. Memory and CPU running very high. Read that we shouldn't be running Search
and Dist Cache in the same server, nor using a WFE as a cache host. I don't have the budget to add another server in my environment.
I found an article (IderaWP_CachingFormSharePointPerformance.pdf) saying "To make use of SharePoint's caching capabilities requires a Server version of the platform." because it requires the publishing feature, which Foundation doesn't have.
So, I removed Distributed Cache (using Powershell) from my deployment and disabled the AppFab. This resolved 90% of server errors but performance didn't improve. Now, not only I'm getting errors now on Central Admin. - expects Dist Cache
- but I'm getting disk operations reading of 4000 ms.
Questions:
1) Should I enable AppFab and disable cache?
2) Does Foundation support Dist Cache? Do I need to run Distributed Cache?
3) If so, can I run with just 1 cache host? If I shouldn't run it on a WFE or an App server with Search, do I have to stop Search all together? What happens with 2 tier farms out there?
4) Reading through the labyrinth of links on TechNet and MSDN on the subject, most of them says "Applies to SharePoint Server".
5) Anyone out there on a Foundation 2013 production environment that could share your experience?
Thanks in advance for any help with this!

That article is referring to BlobCache, not Distributed Cache. BlobCache requires Publishing, hence Server, but DistributedCache is required on all SharePoint 2013 farms, regardless of edition.
I would leave your DistCache on the WFE, given the App Server likely runs Search. Make sure you install
AppFabric CU5 and make sure you make the changes as noted in the KB for
AppFabric CU3.
You'll need to separately investigate your disk performance issues. Could be poor disk layout, under spec'ed disks, and so on. A detail into the disks that support SharePoint would be valuable (type, kind, RPM if applicable, LUNs in place, etc.).

Limitation on number of objects in distributed cache

Hi,
Is there a limitation on the number (or total size) of objects in a distributed cache? I am seeing a big increase in response time when the number of objects exceeds 16,000. Normally, the ServiceMBean.RequestAverageDuration value is in the 6-8ms range as long as the number of objects in the cache is less than 16K - I've run our application for weeks at a time without seeing any problems. However, once the number of objects exceeds the magic number of 16K the average request duration almost immediately jumps to over 100ms and continues to climb as more objects are added.
I'm fairly confident that the cache is indexed properly (as Dimitri helped us with that). Are there any configuration changes that could possibly help out here? We are using Coherence 3.3.
Any suggestions would be greatly appreciated.
Thanks,
Jim

Hi Jim,
The results from the load test look quite normal, the system fairly quickly stabilizes at a particular performance level and remains there for the duration of the test. In terms of latency results, we see that the cache.putAll operations are taking ~45ms per bulk operation where each operation is putting 100 1K items, for cache.getAll operations we see about ~15ms per bulk operation. Additionally note that the test runs over 256,000 items, so it is well beyond the 16,000 limit you've encountered.
So it looks like your application are exhibiting different behavior then this test. You may wish to try to configure this test to behave as similarly to yours as possible. For instance you can set the size of the cache to just over/under 16,000 using the -entries parameter, set the size of the entries to 900 bytes using the -size parameter, and set the total number of threads per worker using the -threads parameter.
What is quite interesting is that at 256,000 1K objects the latency measured with this test is apparently less then half the latency you are seeing with a much smaller cache size. This would seem to point at the issue being related to or rooted in your test. Would you be able to provide a more detailed description of how you are using the cache, and the types of operations you are performing.
thanks,
mark

Error message when using a MessageListener using a distributed cache

Hi --
I'm getting the following error message when I attach a message listener to a distributed cache. I get the same message if I attach the listener to the NearCache in front of the DistributedCache, or to the DistributedCache itself.
My message listener listens for a create() operation and writes the created value out to the database. Both the key and value are java objects that are getting "serialized" when they're pushed in the cache. The listener is never called.
The error spits out two messages, which look like:

Kris,
First of all you should increase the value of logging-config/character-limit element in tangosol-coherence.xml to see the message entirely. The default setting is 4096 which is not enough to see your exception text.
When you do that I believe you will see that the actual exception is java.lang.ClassNotFoundException indicating that the node that has the listener installed doesn't know about the class that is being put into the cache and could be easily fixed as shown here: http://www.tangosol.com/faq-coherence.jsp#classnotfound
Please let me know if that doesn't help.

Distributed cache

HI,
We have a server (Server 1), on which the status of the Distributed cache was in "Error Starting" state.
While applying a service pack due to some issue we were unable to apply the path (Server 1) so we decided to remove the effected server from the farm and work on it. the effected server (Server 1) was removed from the farm through the configuration wizard.
Even after running the configuration wizard we were still able to see the server (Server 1) on the SharePoint central admin site (Servers in farm) when clicked, the service "Distributed cache" was still visible with a status "Error Starting",
tried deleting the server from the farm and got an error message, the ULS logs displayed the below.
A failure occurred in SPDistributedCacheServiceInstance::UnprovisionInternal. cacheHostInfo is null for host 'servername'.
8130ae9c-e52e-80d7-aef7-ead5fa0bc999
A failure occurred SPDistributedCacheServiceInstance::UnprovisionInternal()... isGraceFulShutDown 'False' , isGraceFulShutDown, Exception 'System.InvalidOperationException: cacheHostInfo is null at Microsoft.SharePoint.DistributedCaching.Utilities.SPDistributedCacheServiceInstance.UnProvisionInternal(Boolean
isGraceFulShutDown)'

8130ae9c-e52e-80d7-aef7-ead5fa0bc999
We are unable to perform any operation install/repair of SharePoint on the effected server (Server 1), as the server is no longer in the farm, we are unable to run any powershell commands.
Questions:-
What would cause that to happen?
Is there a way to resolve this issue? (please provide the steps)

Set request timeout for distributed cache

Hi,
Coherence provides 3 parameters we can tune for the distributed cache
tangosol.coherence.distributed.request.timeout      The default client request timeout for distributed cache services
tangosol.coherence.distributed.task.timeout      The default server execution timeout for distributed cache services
tangosol.coherence.distributed.task.hung      the default time before a thread is reported as hung by distributed cache services
It seems these timeout values are used for both system activities (node discovery, data re-balance etc.) and user activities (get, put). We would like to set the request timeout for get/put. But a low threshold like 10 ms sometimes causes the system activities to fail. Is there a way for us to separately set the timeout values? Or even is it possible to setup timeout on individual calls (like get(key, timeout))?
-thanks

Hi,
not necessarily for get and put methods, but for queries, entry-processor and entry-aggregator and invocable agent sending, you can make the sent filter or aggregator or entry-processor or agent implement PriorityTask, which allows you to make QoS expectations known to Coherence. Most or all stock aggregators and entry-processors implement PriorityTask, if I correctly remember.
For more info, look at the documentation of PriorityTask.
Best regards,
Robert

Error handling for distributed cache synchronization

Hello,
Can somebody explain to me how the error handling works for the distributed cache synchronization ?
Say I have four nodes of a weblogic cluster and 4 different sessions on each one of those nodes.
On Node A an update happens on object B. This update is going to be propogated to all the other nodes B, C, D. But for some reason the connection between node A and node B is lost.
In the following xml
<cache-synchronization-manager>
<clustering-service>...</clustering-service>
<should-remove-connection-on-error>true</should-remove-connection-on-error>
If I set this to true does this mean that the Toplink will stop sending updates from node A to node B ? I presume all of this is transparent. In order to handle any errors I do not have to write any code to capture this kind of error .
Is that correct ?
Aswin.

This "should-remove-connection-on-error" option mainly applies to RMI or RMI_IIOP cache synchronization. If you use JMS for cache synchronization, then connectivity and error handling is provided by the JMS service.
For RMI, when this is set to true (which is the default) if a communication exception occurs in sending the cache synchronization to a server, that server will be removed and no longer synchronized with. The assumption is that the server has gone down, and when it comes back up it will rejoin the cluster and reconnect to this server and resume synchronization. Since it will have an empty cache when it starts back up, it will not have missed anything.
You do not have to perform any error handling, however if you wish to handle cache synchronization errors you can use a TopLink Session ExceptionHandler. Any cache synchronization errors will be sent to the session's exception handler and allow it to handle the error or be notified of the error. Any errors will also be logged to the TopLink session's log.

High-units reflect twice the amount with dual JVM's in a distributed cache

HI all,
I have a question - i have a near cache scheme defined - running 4 JVM's with my application deployed to it (localstorage=false) - and 2 JVM's for the distributed cache (localstorage=true)
The high-units is set to 2000 - but the cache is allowing 4000. Is this b/c each JVM will allow for 2000 high-units each?
I was under the impression that as long as coherence is running in the same multi-cast address and port - that the total high-units would be 2000 not 4000.
Thanks...

Thanks...Hi,
the high-unit setting is per-backing map, so in your case it means 2000 units per storage-enabled nodes.
From 3.5 it will become a bit more complex with the partition aware backing maps.

The Security Token Service is not available error on dedicated Distributed Cache server

I have an error on a dedicated Distributed Cache server stating that the Security Token Service is not available. I was under the impression that when Distributed Cache was running on a dedicated server that the only service that should be enabled
is Distributed Cache.
The token service is working as expected on all other servers but this one. Does this service need to be started or should I just ignore this error message?
Jennifer Knight (MCITP, MCPD)

as per my little experience with 2013, if STS is working fine on Web server then I am sure that sharepoint will be fine...Distributed cache stores the ST issued by STS. NO need to worry about this error.
Login
Token Cache
DistributedLogonTokenCache
This
cache stores the security token issued by a Secure Token Service for use by any web server in the server farm. Any web server that receives a request for resources can access the security token from the cache, authenticate the user, and provide access to the
resources requested.
I would say check the ULS logs and get more details about the error why its not working on that server.
Please remember to mark your question as answered &Vote helpful,if this solves/helps your problem. ****************************************************************************************** Thanks -WS MCITP(SharePoint 2010, 2013) Blog: http://wscheema.com/blog
