Multi-Layer Cache Servers
Is there any other way to configure multi-layer cache server client select other than with IP addresses?
Thanks

It might lead to replication conflicts if people in the branch offices
do administrative changes to AD. But unless replication resumes within
the tombstone lifetime, this is not a critical issue.
The only point in fact is tombstone lifetime (and of course, Sysvol
replication -> DFSR maxage).

Does anybody have some usefull links or information regarding CEF/Multi-layer switching? How are these features interacting with each other? Key differences?
Thank's a lot.
FlorianHi Florian,
Basically in MLS the first packet to reach the destination rill need to be processed by router as it just maintain the caches and so for second packet it gets wr writed in hardware.
But in CEF even the first packet is hardware switches as it builds the adjacency table and FIB table. Which not only maintains the routing entried but also the arp entried like binding the mac with ip so that even first packet can be hardware switches.
Have a look at this white paper for CEF

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.

Multi-layer/layer3 switch VS. Router
Multi-Layer Switch or Layer3 switch vs. router; How they are different?
1.7In a router the route calculation and packet processing take place in the software on layer 3. This means that packets need to be moved from the layer 2 hardware interface to layer three and so it takes some time. In a layer 3 Switch Routing calculations takes place at layer 3 in hardware or software, while the actual packet processing takes place at layer 2. The speed gain is accomplished by reducing the amount of features supported and moving as much logic as possible into hardware.

On an iPad, how can I view just the text layer of a multi-layer PDF?
I have a PDF which has 4 layers. They are all visible at the same time through the Adobe reader app.
This is un-readable. How can I select just one layer to view at a time?I found a post that Fuji Xerox Docuworks Viewer Light reads PDF layers but I could not verify as it's not sold in the USA App Store.

Hi All,
I have created a simple console application which will get the Cache from the cache server.
However i am getting the below error. my cache server is up and running. could any one help ?
ErrorCode<ERRCA0017>:SubStatus<ES0006>:There is a temporary failure. Please retry later. (One or more specified cache servers are unavailable, which could be caused by busy network or servers. For on-premises cache clusters, also verify the following
conditions. Ensure that security permission has been granted for this client account, and check that the AppFabric Caching Service is allowed through the firewall on all cache hosts. Also the MaxBufferSize on the server must be greater than or equal to the
serialized object size sent from the client.)
Below is the code
static DataCacheFactory _cacheFactory = Initialize();
static void Main(string[] args)
var cache = _cacheFactory.GetCache("Given the Cache name"); // getting an error here
var Key = "mykey";
var obj = cache[Key];
if (obj == null)
obj = "Sample";
cache.Add(Key, obj);
Console.WriteLine("Object added");
else
Console.WriteLine("Object was already in cache");
Console.ReadLine();
static DataCacheFactory Initialize()
var Config = new DataCacheFactoryConfiguration();
var Servers = new List<DataCacheServerEndpoint>();
Servers.Add(new DataCacheServerEndpoint("Given the cache host name", 22233));
Config.Servers = Servers;
var temp = new DataCacheFactory(Config);
return temp;
NavaneethConfig.SecurityProperties = new DataCacheSecurity(DataCacheSecurityMode.None, DataCacheProtectionLevel.None);
After setting the above property it worked!

It's possible to make a multi-layer filter plugin? The idea is: the user has open a multi-layer document, then execute the plugin and selects N layers of the document in the filter UI, and when clics "OK", the plugin create a new layer adding every selected layer pixel by pixel.
LAYER A LAYER B RESULT LAYER
0 0 5 5 5 1 1 2 1 1 1 1 7 6 6
0 0 0 5 5 + 1 1 3 1 1 = 1 1 3 6 6
0 0 0 0 5 1 2 3 2 1 1 2 3 1 6
Any advice?
Thanks!A filter plug-in can read from any layer using the channel ports suite. See the Poor Mans Type Tool example. A filter plug-in can only write to the active layer. You cannot add a layer from a filter plug-in. You would need the auto/filter combo as Chris talks about. See the autofilter/hidden combo example or the format/auto for importing text files example.

ACE for Cache servers how-to??
We have ACE10 installed on 7609 Internet-router, we intend to force Internet http traffic on the 7609 to a third party Cache servers without using either PBR or WCCP to obtain backbone bandwidth savings. In addition the ACE will distribute the http traffic to the cache servers which are 8 in number. Can anybody help out with how to do it (some reference documents will be appreciated).
HI,
The ACE uses the predictors to select the best server to fulfill a client request.
Use the Hash URL method as predictor as it selects the server using a hash value based on the requested URL. You can specify a beginning pattern and an ending pattern to match in the URL. Use this predictor method to load balance cache servers.
Cache servers perform better with the URL hash method because you can divide the contents of the caches evenly if the traffic is random enough. In a redundant configuration, the cache servers continue to work even if the active ACE switches over to the standby ACE.
You have to understand the reason of url hash.
The goal is to guarantee that the same object will not be cached on mayne servers and therefore maximise disk usage.
So, if you don't really need to maximize this disk usage, you could use any other balancing method.
There is not one-best-for-all solution.
It all depends on what are your priorities.
Kindly see how to configure Hash URL method Below:

__Is there a way to make a multi-layer Ai file into a multi-page PDF? (1 layer per page)
__Is there a way to make a multi-layer Ai file into a multi-page PDF? (1 layer per page)
thanksDefinitely can be done.
In CS 4 you create an artboard for each page and the position the art for the corresponding page on the corresponding artboard and make a layer for that art. This way it does not even matter if the layer s are properly layered when saving the pdf. Just as long as the artboards are.
CS 3 and earlier back a larger document that can be divided into whole pages by turning on tiling and using the page tool position that art.
Position the art for each page over the designated artboard make a layer for each pages art now when you export the with tiling on and you wll get a multi page pdf. -

So I had to make a SSD or sequence Diagram now we have to make a multi design diagram?
for the multi design. will we just be creating one big diagram of the assignment for this part?
or is it going to be a collection of a bunch of separate diagrams. as books shows a few of them? regarding layers?
For example create a diagram to cover all different layers/steps
So should be a collection of 3 or more diagrams for Part 3 of TMA3
do I have this correct?Just click on "Buy" one at a time. If you do them all in one sitting, they will be grouped as a single charge on your credit card.

After Effects CS6: ***Layer Cache Indicators*** issues
I guess i jumped the guns too soon on the CS6 upgrade (from CS5.5 Production Premium) as I've discovered quite a major issue with one of the selling points of this product.
The issue is with After Effects CS6, as enabling Layer Cache Indicators is not available. You can only select to show the global cache indicators (thats the render blue/green line on top of all the layers), but i really wanted to see the render bar for each of the layers, which was heavily advertized upon release of CS6.
Adobe, you have to fix this asap, release an update. This feature is available in CS5.5 (I've checked) but no where can i find to enable it in CS6.
PLEASE HELP!Its the Timeline panel menu, that yellow button on the top-right corner within the timeline. That opens up a menu, hold CNTRL + select show cache and the render bars going to appear on each of the layers. This should work for MAC i think.

Hibernate's dual-layer cach and TopLink's caching strategy
Dear members,
I understand that caching between hibernate and toplink is implemented (or utilized) differently. Hibernate seems to have 'dual-layer caching' (which may imply they have two layers of cache) whereas TopLink has session cache and shared cache. The way I see it, they seem to be aiming for the same thing. Are there any differences between (obviously there are, only that I do not know them) those two caching architectures, and how different are they?
HowardYes there are differences :) For details check out

How to write a multi threaded Cache Event Listener
I have a distributed data cache called tokenCache for my application. I have also added a mapListener to this cache to listen to a particular kind of events.
tokenCache.addMapListener((MapListener) new TokenCacheListenerBean(), new MapEventFilter(tokenFilter), false);
So bascially everytime a token (The domain object of this cache) is updated the entryUpdated() method in my EJB TokenCacheListenerBean is invoked.
The issue I have though is that, from what I observe on running my code is that the Cache Listener is single threaded. So if two Token Objects on my tokenCache are updated,
lets say Token Object A and Token Object B one after the other, the entryUpdated() method in my EJB is invoked for Token Object A and once the invocation is complete
then the entryUpdated() method is invoked again for Token Object B(). At a given point of time there is only one instance of TokenCacheListenerBean EJB. Is there a way to
make this happen in multi-threaded manner ?
Is there a configuration setting somewhere which allows multiple CacheListeners to be instantiated at a given point of time ?

}Here is what I am asking!
I have added 2 listeners (Listener A and Listener B) which each listen on for changes made to 2 different token Cache Objects (Token A and Token B).
for (i = 0; i < 2 ; i++) {
Token tokenAdded = new Token(UUID.randomUUID().toString(),TOKEN_AVAILABLE, networkID);
tokenCache.put(tokenAdded.getTokenID(), tokenAdded);
tokenCache.addMapListener((MapListener) new TokenCacheListener(), tokenAdded.getTokenID(), false);
Now assume that updates are made to Token A and Token B simuntaneosly.
Why do i observe in my diagnostic messages that only one Listener is invoked at a given point of time.
Which means I see Listener A getting invoked and then once invocation of Listener A is complete I see Listener B bieng invoked.
Ideally I would want both listeners to be invoked simultaneously rather than in a one off fashion.

How do I stop 10.9 caching servers sharing content with other peers?
We have a problem on a school district network where Mac Servers are sharing their caching content with their registered peers. We have set MaxPeersToQuery to 1 but can't set that value to Zero. We have tried PeerRangeFilters array but that doesn't work either. Apple documentation seems to include a double negative. We have no access to the network, that is controlled by the Local Authority. We just need a Mac Server within a school to only serve the local subnet (The option is ticked) and not query any peers for assets. Any help appreciated.
What was the values you set for PeerRangeFilters? Based on the documentation, this sounds like it should be able to provide what you are looking for.
But it sounds like you are trying to control two different things here. It sounds like you want to make clients from each subnet access the subnet's server. That can be accomplished by using the ListenRange key on each server. For example, if you have a server on a 172.16.0.0/24 you can define that server to listen only to client requests from that range. Then your server on 172.16.1.0/24 can be configured to listen on that subnet range.
The second thing you are trying to limit is the sharing across the servers based on peer sharing. I have not attempted this before but the PeerRangeFilter sounds like the right thing. Share what you configured.
