Help On coherence
Hi all,
I am new to coherence.Trying hard to make it working on weblogic 10.3.3.I am using TopLink with JPA at ejb side.And wanted to use coherence cache instead of TopLink cache.I have done custome config for coherence through weblogic admin console by providing coherence-cache-config.xml.Though I don't see any coherence logs when i run my client.
Please let me know,If anyone has used weblogic 10.3.3 coherence with toplink.
Thx-
rakesh

Hi Paul,
Thanks for reply.
I am using weblogic 10.3.3 provided coherence.I followed http://wiki.tangosol.com/display/COH33UG/Using+Coherence+and+TopLink+Essentials this link to configure it.
I dont see any coherence related logs when I am fetching entities through my ejb client.
Please let me know,Is this correct way to configure it?
Note:I am using TopLink Essentials
Thx-
rakesh

Help on Coherence + Weblogic Cluster configuration
Hi,
I am new to Coherence. I am exploring coherence to fulfill one of my requirement.
My requirement : I have an application deployed on a Web logic Server clustered environment. I need to cache the application specific data(java maps) and that should be available for all nodes of the WLS cluster. The application data that's being cached, can be updated from any of the node from the WLS cluster and updated application data from the cache should be available for all the nodes of the WLS cluster. The nodes in the WLS cluster resides in different machines from different locations.
Can I use coherence as a caching services for my requirement?
If Yes, do I need to start a coherence cache server on each node of the WLS cluster?
If yes, do I need to specially configure these cache servers, so that these cache servers would communicate each other in case of any data updates in the cache?
It will be great help if you could also provide sample configurations to achieve the above scenarios.
Thanks in advance!
regards,
Srinivas MYou can start one cache server in the network by using for example
# home directory
BEA_HOME="/home/oracle/bea"
export BEA_HOME
# java vendor (for example Oracle or Sun)
JAVA_VENDOR="Oracle"
export JAVA_VENDOR
# cache server klasse
CACHE_SERVER_CLASS="com.tangosol.net.DefaultCacheServer"
export CACHE_SERVER_CLASS
# coherence options
COHERENCE_OPTIONS="-Dtangosol.coherence.management=all"
export COHERENCE_OPTIONS
COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.management.remote=true"
#COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.cacheconfig=WEB-INF/classes/session-cache-config.xml"

export CLASSPATH
# start the cache server
${JAVA_HOME}/bin/java ${MEM_ARGS} ${COHERENCE_OPTIONS} ${CACHE_SERVER_CLASS}The -Dtangosol.coherence.management=all option gives you some handy information on what the cache is doing by using for example the mbean browser provided by jconsole or jrockit mission control.
You can create an application in which you create a cache, the following shows an example of a servlet
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Random;
public class TestServlet extends HttpServlet {
private NamedCache movies;
public void init() throws ServletException {
movies = CacheFactory.getCache("repl-movies");
movies.put(10, new Movie(10, "Rear Window", "Alfred Hitchcock"));
movies.put(20, new Movie(20, "Vertigo", "Alfred Hitchcock"));
movies.put(30, new Movie(30, "Double Indemnity", "Billy Wilder"));
movies.put(40, new Movie(40, "Touch of Evil", "Orson Welles"));
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Integer[] integers = {10, 20, 30, 40};
Random random = new Random();
while (true) {
movies.get(integers[random.nextInt(4)]);
}Package the servlet into for example a WAR file and deploy it to a configured WebLogic cluster.
By accessing servlet on the different nodes of the cluster a new cache gets created and added to the
already running DefaultServer.
The hard part is to configure your cache. As you can see in the servlet init we ue something like CacheFactory.getCache("repl-movies");
Coherence default with some example cache configurations which are contained in the coherence.jar (coherence-cache-config.xml).
The following entry is used
<cache-mapping>
<cache-name>repl-*</cache-name>
<scheme-name>example-replicated</scheme-name>
</cache-mapping>
<replicated-scheme>
<scheme-name>example-replicated</scheme-name>
<service-name>ReplicatedCache</service-name>
<backing-map-scheme>
<local-scheme>
<scheme-ref>unlimited-backing-map</scheme-ref>
</local-scheme>
</backing-map-scheme>
<autostart>true</autostart>
</replicated-scheme>A replicated cache is probably what you need as well. As you want all the data to be available on all nodes. If you want to use
your own cache configuration you can add the option -Dtangosol.coherence.cacheconfig (see the start script for the default server)

Help with Coherence EntryProcessor design
Hi Gurus,
We are in the process of designing our End Of Day Trade processing application on Coherence 3.7.1, the use case is as under
1. Trades coming through JMS channels are split in to Parent Trade + Child SubTrades, these trades and subtrades are placed in to their respective cache, collocated by Key Affinity.
2. We want to use Entry Processors to process each type of SubTrade and update the Parent Trade (An EntryProcessor per SubTrade Type).
3. Once all SubTrades are processed, The Trade reaches the Completed State and should be Audited and removed from the cache with all its SubTrades.
The EntryProcessors are working fine on preloaded Cache, Can you Gurus please verify the approach and please advise us how to extend it further for Trades being added to the cache after the invocation of the EntryProcessors, i.e we want to call these processors recursively. Is there a way to know when all EntryProcessors has completed so a new Execution for the same can be initiated, we want to avoid a number of event processors lined up unnecessarily.
Regards
Edited by: 965684 on 17-Oct-2012 03:10They probably liked your style ( on the green logo ) and want to incorporate it into their packaging. You should be honest and tell them you do not have any experience. They'll probably bring you in at "entry level" so they can groom you to their corporate culture. You'll probably be working under a senior designer and will probably spend a few months learning how things are done. I'd imagine you'll need some basic knowledge of Illustrator and Photoshop, if not some intermediate level capabilities with both programs.
Now, if you want to impress them, find a current package the company had produced in the last few years. Pull it apart and get it to lie flat. Re-create the entire piece using Illustrator. This will include a spot layer with dies. Focus on improving the design and look of the piece, but make sure you do not copy what has already been done. Come up with something original and incorporate your version of the "green" logo. It does not have to be anything out-of-sight, but shows you know the company, you know how to improve the existing packaging out there, and you'll show initiate. They'll probably never use it ( like your "green" logo, but will get you the job ).
This will take you some time. I do not know of any web tutorials, but both Illustrator and Photoshop come with a few. You could also go to a local bookstore and take alook at what they have in their "graphic design" section. Some books come with a CD that has some templates and files you can take a look at.
There must be a void they're looking to fill, otherwise you'd never get the interview. Don't get too stressed out trying to impress them. They're already impressed. But, if you "claim" to know it all in software, you'll be doing yourself a huge injustice. Talent does not come in a box. Sounds like they're willing to get you started, so go for it. -
How can I measure coherence between EEG signals using labview?
well, I have an EEG signal(a matrix 16X8498)whose lines represent the channels and collums the samples. The last line is the stimulus channel. I would like to know if I can measure the coherence between my EEG channels(lines)using labview.If,yes,is there someone who has the block diagram?
Search the Labview help for coherence and you'll find several functions (in Labview 6.1 Full Development System). The functions are in the palette Analyze >> Waveform Measurements >> Frequency Response Function (Mag-Phase) or (Real-Im).

Latency problems between nodes
I'm looking for some help debugging coherence in a weblogic environment where we are having problems with (what seems to be) the latency of calls between coherence nodes both on the same box and on different boxes.
The application is a standard 3 tier java app which uses hibernate as its persistence provider and coherence as the L2 cache provider.
The target architecture is the application clustered in weblogic (in my test environment it is over a pair of boxes, in production this will scale out horizontally). The managed server JVM's will join the coherence cluster as nodes but set to not store data locally (we would like to reserve all the heap for the app) and then have (multiple?) coherence nodes on each physical server (we need to play with heap sizes and gc to best understand how we leverage the physical memory on the box) to support our caches.
We have seperate caches for each entity that is cached but to start of with they are all partitioned (as we work through testing we'll obviously play with the configurations for the different groups of entities as appropriate).
The coherence cluster is using well known addresses to find nodes but we haven't got into overriding any of the other values in the tangosol-coherence-override.xml file.
The simplest test case for demonstrating this behaviour is a single user logging in executing a particular search logging out, logging back in executing the search etc. etc.
If I have only one JVM running for the application (the managed server which has the application on) and for the sake of these tests set it to store local data so essentially the cache is running in process (like a replicated cache essentially). The we get a flat line of performance of 5 seconds per search. This is fine as a starting point but I obviously want to scale it out.
If I now start a coherence server node (launched from with weblogic) on the same physical machine (it happily joins the cluster) and run the same test I get a flatline of performance of 11 seconds. This really surprised me as I'm only sharing data between 2 processes on the same box yet we seem to have introduced a latency of 6 seconds.
Finally if I now start the full cluster, so I have 2 managed servers in a cluster (not storing data locally for this test) and each physical machine also has a coherence node on it the test flatlines at around 18 seconds. So we've introduced some more significant latency where the data maybe potentially on another box (but as I understand it coherence guarentees its only ever 1 hop away).
We're running on solaris 10 and the boxes aren't stressed for CPU or memory during the tests. Equally if I monitor the JVM's health they seem fine. I've also bumped up the coherence logging to 9 but don't get anything additional that looks worrying.
Is there anything obvious I am missing and if not how can I start to understand the problem more.
Thanks in advance,
Paul Fitz.Thanks for the response. Just to clarify 5 seconds is too long but for now its just my baseline (it should be less than that but that’s within the control of the dev team, in fact someone is checking in a fix to a mistake in the algorithm at the moment which brings that down to something more sensible). This is still with caches defined as partitioned but with only one JVM running that is hosting both the application and is acting as a coherence node storing data. It’s not the target architecture but to baseline what’s the quickest this will go based on the assumption that optimum throughput will come if the cache is in the same JVM as the app.
Moving towards the target architecture I then run the same test but with an additional coherence node started on the same physical box as my application JVM (so when I talk about hops I mean when hibernate looks for data in its L2 cache its either going to be in the node running in the same JVM as my app or in the node running as a separate JVM but on the same box). The searches now consistently come back at 11 seconds so as nothing else has changed the extra 6 seconds seems to come from the data coming now from 1 of 2 JVM’s (coherence nodes) running on the same machine as opposed to always being in the same JVM.
The final tests (in reality we started with this the target architecture and worked backwards to see where we were loosing time) is then bringing up nodes on the second box in the cluster which adds an extra 6 or 7 seconds to searches. In some respects I could understand this more and can debug traffic going out on the network between the cluster members and see if its being sent around the houses so to speak by the network and try some of the things mentioned above. What makes less sense is the second scenario where all we’ve got is inter process communication going on in the same box. I'll look at the actual size of the data being passed between the 2 processes because your post has made me question the cost of the serialization process thats happening (nothing more than standard java at the moment).
I’ve also got a couple of dev windows boxes on a different network so I’m inclined to quickly stand them up with the code and see if I can replicate the same increase in response times between the different configs. This should give me a feeling for if its something to do with my NFR environments and from that if its networks, interaction with a different o/s etc. -
Coherence Cluster Errors- Need your help to solve
Hi,
We had this error recently in QA and these servers are not new servers. These servers were running from some time and in good condition.
We had a below error happened suddently and cuased servers outage for some time.
After restarted all the servers, this issue has gone.
We are trying to understand the root cause to avoid this issue in future and need expertise in this forum for that.
Brief summary of issue
1. We had performed multicaste testing on the coherence cluster IP and port and all the communication is good.
2. Issues started with error of Unable to refresh sockets:
Stopping cluster due to unhandled exception: com.tangosol.net.messaging.ConnectionException: Unable to refresh sockets: [UnicastUdpSocket{State=STATE_OPEN, address:port=1.1.1.85:8088}, MulticastUdpSocket{State=STATE_OPEN, address:port=239.3.1.17:35122, InterfaceAddress=10.137.3.85, TimeToLive=1}, TcpSocketAccepter{State=STATE_OPEN, ServerSocket=1.1.1.85:8088}]; last failed socket: MulticastUdpSocket{State=STATE_OPEN, address:port=239.3.1.17:35122, InterfaceAddress=10.137.3.85, TimeToLive=1}

4. Continously logging errors like : Rejecting connection to member 3 using TcpSocket{State=STATE_OPEN, Socket=Socket[addr=/
5. After that noticed,

Need a help to update coherence cache values in c++
Hi,
I need to update coherence cache value of a particular object.
Managed<ExposureHolderContract>::Handle contract =
cast<Managed<ExposureHolderContract>::Handle>(cache->get(vsName));
contract->setName("dsafd");
When i try to cast to a ManagedObject:: Handle it says
coherence::lang::ConstCastException: attempt to cast from a "const coherence::lang::Managed<ExposureHolderContract>" to a "coherence::lang::Managed<ExposureHolderContract>"
at void coherence::lang::coh_throw_const_cast(const std::type_info&, const std::type_info&)(ConstCastException.cpp:27)
at coherence::lang::coh_throw_const_cast(std::type_info const&, std::type_info const&)
<stack frame symbol unavailable>
<stack frame symbol unavailable>

at __libc_start_main
on thread "main"
In the documentation it says in order to call non static methods we need to retrieve the handle.
but when I try to cast to a handle it fails.
I'm inserting data to coherence cache by calling Managed::create method. Is this method making immutable object.
ExposureHolderContract tempEhc(contractId, name, date, age, weight);
Managed<ExposureHolderContract>::Handle ss = Managed<ExposureHolderContract>::create(tempEhc);
cache->put(String::create(contractId.c_str()), ss);
Please help me to update the recorde value.
regards,
suraHi Sura,
It is a matter of safety and correctness. The in-process caches return a locally held object, and thus if you made some change to it, that change would be visible within the in-process cache, while not visible to the remote cache. Thus future access to the in-process cache would see a value which does not actually exist in the remote cache. While it is true that if you modify it with the intent to immediately re-insert it this shrinks the window of incorrectness that window still exists, and of course the cache has no idea if you will ever reinsert the value. As for the effect on performance it should be insignificant if you actually do put it back in the cache as the cost of a cache update will easily be multiple orders of magnitude greater then the cost of the clone. Also remember there is no requirement to clone a value if you don't intend to mutate it, you can safely use it via the View. So the only time the performance cost of the clone could be considered significant is when you intend to mutate but not reinsert the data, but a clone is also necessary there as not cloning it would leave the in-process cache in an inconsistent state with respect to the remote cache.

Oracle Coherence -
I'm currently undergoing a technical evaluation of Coherence and am finding a number of problems, the most pressing of which is that the documentation is not wholly helpful as it doesn't explain some basics about the software (at least, I can't find the information I want).
As part of the evaluation, I am attempting to implement a distributed cache of product data which can be read from a number of different applications.
PRICING:
It is not clear to me that if an application is looking up data in the cache, whether Coherence's pricing model means that we must pay for the CPU of that application (i.e. applications could be thought of as running inside a Coherence container which must be paid for). The alternative scenario is that the data resides on a number of Coherence servers (for which we must pay) but that any number of clients can access the cache without paying for every single client.
We have a (I would have thought) modest number of internal applications which want to access data on 6 blades, each of which has 2 quad-core processors. With the enterprise edition, the "Container" model would cost us $240,000 for the Enterprise edition (assuming a quad-core processor = 2CPUs) which is a mind-boggling amount for what is (I would have thought) a small deployment. From my experience thus far, however, Coherence would seem to follow this model
BASIC QUERYING:
I have implemented a basic cache of product data and have encountered a problem with terrible querying performance using ValueExtractors. Basically a pretty basic non-key-based lookup is taking around 100ms (this is with 2 nodes on the same machine), even if I repeatedly lookup data using the same extractor and even when my data is not being written to. Why is this? Am I missing some configuration to use Smart-caching of query results. Surely the client API should be aware of whether the data has been changed (jn another node) and therefore whether it can just run the query of the data in the local VM? An ID-based lookup is sub-millisecond (but only just) by comparison and taking the cache's size takes about 3ms.
Of course, this could be the serialization overhead of the ValueExtractor but that would mean that querying for individual items using an extractor is effectively unusable.
I'm not dissing Coherence here as I'm sure it's a fantastic product and that it's just the case that I can't find the information I need to answer my questions

In case your query depends only on the content of the cache, but no outside or variable factors, like time, then Coherence provides the Continuous Query Cache which reevaluates changed entries for being included or evicted from query results and practically maintains an up-to-date query result on the local node.
The trouble here is that I am maintaining a cache of (financial) product data and wish to be able to query for individual products by any one of a number of "code types" individually - e.g. ISIN, RIC, TICKER etc. Keeping alive a continuous query to perform what is essentially cache.lookup(CodeType.RIC, "JAVA.O") would not be an option because an application may need to query tens of thousands of products.
With indexing, I have got the query down to around 3ms but this really not the sort of performance I was looking for. I would have to build a caching layer on top of Coherence (i.e. on top of a cache)!
And I expect you wanted to write Coherence not Confluence :-)Oops :-)
Also, I found Coherence pretty easy to evaluate even 3 years ago and it only became easier since then due to the abundant information in the Wiki pages.I have been plagued by appalling page load times, various error pages on the Oracle website. From the Oracle website, the documentation is difficult to find; the docs bundled with the install are much more helpful. That said, the docs for GigaSpaces are better laid out and better structured from an evaluation point of view. (GigaSpaces seems to fundamentally lack a feature that we need by the way - I am not "bigging" up the GigaSpaces product!) -
Coherence Help standalone java program put data in cache & Servlet to Read
Hi,
I have coherence 3.4 and using Oracle Application Server 10.1.3 We are in the process of developing a Web Application and want to use Coherence for caching the data. My Coherence is also installed on the same box as Oracle Application Server 10.1.3 need some help in storing the data in the coherence and reading it through the servlet. We have standalone java program that needs to put data in the cache and through servlet want to read that and display it on the page. When running the client the data is stored in the cache but when reading it through the servlet it returns null. We have included both coherence.jar and tangosol.jar in the war file and also in the path when running the standalone java program. Started the Coherence using the below command:
C:\oracle\coherence\lib>java -cp coherence.jar -Dtangosol.coherence.cacheconfig=C:/oracle/coherence/tests/cache-config.xml com.tangosol.net.DefaultCacheServer
here is the sample config file used when starting the server above:
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
<caching-scheme-mapping>
<cache-mapping>
<cache-name>VirtualCache</cache-name>
<scheme-name>default-distributed</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<!--
Default Distributed caching scheme.

<distributed-scheme>
<scheme-name>default-distributed</scheme-name>
<service-name>DistributedCache</service-name>
<backing-map-scheme>

<scheme-ref>default-backing-map</scheme-ref>
</class-scheme>
</backing-map-scheme>
</distributed-scheme>
<class-scheme>
<scheme-name>default-backing-map</scheme-name>
<class-name>com.tangosol.util.SafeHashMap</class-name>
</class-scheme>
</caching-schemes>
</cache-config>And here is the standalone java program to put the data in the cache:
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
public class PutCache {
public PutCache() {
public static void main(String[] args) {
PutCache putCache = new PutCache();
NamedCache cache = CacheFactory.getCache("VirtualCache");
String key = "hello";
cache.put(key, "Hello Cache123123");
}And here is the Servlet code to read the data but it somehow returns null
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.*;
import javax.servlet.http.*;
public class Servlet1 extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
NamedCache cache = CacheFactory.getCache("VirtualCache");
String value = (String)cache.get("hello");
out.println("<html>");
out.println("<head><title>Servlet1</title></head>");
out.println("<body>");
out.println("<p>The servlet has received a GET. This is the reply.</p>"+value);
out.println("</body></html>");
out.close();
}Is there any other configuration I need. Any help is really appreciated.
ThanksHi,
While starting the coherence using
C:\oracle\coherence\lib>java -cp coherence.jar -Dtangosol.coherence.cacheconfig=C:/oracle/coherence/tests/cache-config.xml com.tangosol.net.DefaultCacheServer
while running standaone jave program using the below command
java -Dtangosol.coherence.cacheconfig=C:/oracle/coherence/tests/cache-config.xml Populatecache
In the Web Application don't have any reference to cache-config.xml just using the coherence.jar & tangosol.jar.
What are the steps or configurations I need in order to connect to the same Coherence Cache. Do I need to provide some host:port for the Coherence for storing the data in the cache. How does the java client program and Web Application knows to connect to the Coherence. As currently even if I don't start the coherence server and just run the java standalone program it goes and executes fine wondering wher exactly does it persists the cache if coherence itself is not started or just adding the jars is enough. Any help is appreciated.

Regarding Coherence Replication... Please help
Hi,
Please go through the following scenario which need to implement and suggest me accordingly.
Scenario:
There is a service ABC (say). Our java application will receive an XML file from ABC for every 3 minutes. When we receive the first XML file, We have to store that XML data in Coherence cache and should replicate it to other instances. When we receive the next xml file (for the 3rd minute) , we should overwrite the data in the cache with this new data. Like this we should keep on overwriting the data for every 3 minutes. When some invokes our application, then we should retrieve the XML data from cache and should provide it.
Can anyone please explain me how to implement it using coherence.
Thanks a ton,

NamedCache cache = CacheFactory.getCache(<CACHE_NAME>);

and should replicate it to other instances.If you truly want the XML replicated to each cluster node configure the <CACHE_NAME> to map to a replicated-scheme in your cache configuration file. If you want the XML objects to be partitioned across the cluster, thus allowing for linear increase of cache capacity as you add JVMs to the cluster, you should configure the <CACHE_NAME> to map to a distributed-scheme in your cache configuration file. I would highly recommend that latter.
When we receive the next xml file (for the 3rd minute) , we should overwrite the data in the cache with this new data. Like this we should keep on overwriting the data for every 3 minutes.
cache.put(key, XML);
When some invokes our application, then we should retrieve the XML data from cache and should provide it.Then all your application needs to do is:
NamedCache cache = CacheFactory.getCache(<CACHE_NAME>);
XML = cache.get(key);Rob

Hi, we have been tasked with the creation of a VM image which has WebLogic Server, Coherence, Oracle Database XE etc. And I am a newbie to it Do you have any tips to help me get started?? Thanks and regards Anil
I never tried it, but when you're booting from a OVMs 3.2.7 CD you can choose the p2vm option, which I assume, would convert your installation into a guest fpr OVM.
Maybe you should read up on that in the OVM documentation. -
Coherence*Web on GlassFish Server Issues
Hi!
We are using Coherence 3.7.1.8 in our application in GlassFish 3.1.2 both as application cache and for storing session data (Coherence*Web) so it can be shared between multiple EARs and App server instances. Session data sharing between EARs in the same container works fine, but when we try to share session data between application server instances the server stops responding and has to be restarted. The only thing we get on the log is this exception:

Multiple iCloud accounts / iOS 8 iPhone cellular / Coherence
Hello,
My partner and I share a photo library, a music library, and a keychain. In iOS 7, we would just sign into the same iCloud account, and then for FaceTime and iMessage sign into a different account, each respective account associated with our own iPhone mobile number.
It seems this strategy doesn't work in iOS 8 -- to use iPhone cellular or Coherence, you have to be signed into the same account.
Associating the accounts mentioned above under a family account doesn't help.
If each of us signs into our own iCloud account, we will have different Photo Streams which for now means our pictures can't both end up in the same iPhoto library, and, down the line, we will need iCloud Photo Libraries (probably 500 gigs worth), with no good way to sync them across accounts. We would also lose shared keychain. We could keep the same music library because of the family account.
Is there any way to work around this? Ideally, we would sign into our own iCloud accounts but for Drive, Photo Stream/Photo Library, and Keychain, be able to connect that feature with another library. Or at least have a way to share the whole library between accounts, not just the single Family Album.
Thanks!EDIT: It seems this strategy doesn't work in iOS 8 -- to use iPhone cellular or Coherence, you have to be signed into the same account in FaceTime as the main iCloud account.

How to specify index for cache in coherence-cache-config.xml

We want to apply indexing on cache data.
Suppose i have a EMPLOYEE object in coherence cache.
and i want to use employeeID for indexing purpose.
Can anybody help me to achieve this at Congregational level i.e. using xml file (coherence-cache-config.xml) .
