Tangosol 2.5.1 and WKA

Hi,
Can anyone confirm whether WKA (Well Known Addresses) is supported in v.2.5.1?

Pinakin,
The multicast-less discovery protocol (WKA) was introduce at Coherence 3.0 and is not supported for 2.5.x.
Regards,
Gene

Declaring "tangosol.pof.enabled=" and "tangosol.pof.config=" in xml config

Dear all,
Is there a way to declare "tangosol.pof.enabled=true" and "tangosol.pof.config=my-pof-config.xml" in coherence xml config (e.g. tangosol-coherence-override.xml) ratherthan using the "-Dtangosol.pof.config=" and "-Dtangosol.pof.config=".
We are looking for this because deploying the same config file on both our application servers and our pure coherence nodes is the easiest way we have to be sure that the configurations are in sync.
We have lost several hours last week figuring that we forgot to declare these "-Dtangosol.pof..xxx" environment variables in our J2EE servers and we would like to prevent this to reoccur.
Cyrille

For versions earlier than 3.6, if you don't want to set POF to be the default with the tangosol.pof.enabled switch, you have to add the full serializer definition to your cache config:
<serializer>
<class-name>com.tangosol.io.pof.ConfigurablePofContext</class-name>

<init-params>
<init-param>
<param-type>String</param-type>
<param-value>pof-config.xml</param-value>
</init-param>
</init-params>
</serializer>
From Coherence 3.6, you can add a <serializer/> element to the scheme in
the cache config file:
<distributed-scheme>
<scheme-name>example-distributed</scheme-name>
<service-name>DistributedCache</service-name>
<serializer>pof</serializer>
You can also define the default serialisation method in the cache
config file:
<cache-config>
<defaults>
<serializer>pof</serializer>
</defaults>
Both of these refer to a set of serializers defined in the operational config file that you can override using an
operational overrides file. E.g.

<?xml version="1.0" encoding="UTF-8"?>
<coherence>
<cluster-config>
<serializers>
<serializer id="pof">
<class-name>com.tangosol.io.pof.ConfigurablePofContext</class-name>
<init-params>
<init-param>
<param-type>String</param-type>
<param-value>my-pof-config.xml</param-value>
</init-param>
</init-params>
</serializer>
</serializers>
</cluster-config>
</coherence>

Coherence and Multicast Issues

We are using Coherence 3.7.1 as a part of EAR application. These are deployed on WL Servers using multicast. We have observed if multicast is disabled on a node while deployment but enabled later, id does not joins the cluster, A redeployment is required after multicast is re-enabled.
Any suggestions on this will be appreciated.
Though one option option is to run the the multicast-test.cmd utility manually before deployment and view the result, is there a way to automate this process without manual intervention.
Using Unicast and WKA are not possible
Looking forward to suggestions.

This sounds like a problem in lccs. Could you check the difference in code in WebcamSubscriber#playStream() between 10.0 and 10.1? (I cannot do this as 10.1 is not open source.) Whatever the problem is, it's initiated from that method.

Issue with "unknown user type 6" on Coherence 3.5.2

Having an issue with a cluster which is running using an internally developed cluster starter tool. This tool, and the associated cluster, all use POF, and upon attempting to connect a non-storing member to the cluster from java, the following exception is raised...

There is no serialiser configured in the cache config, instead we just set tangosol.pof.enabled=true, and set the pof config file to what is seen above. The thing which is very confusing about this error is that unlike other clients which we connect, and in fact the servers they connect to, this client never attempts to load the cache configuration file. The point at which this should happen, prior to pof loading, shows:
2011-07-11 15:54:57.260/1.391 Oracle Coherence GE 3.5.2/463p2 <Info> (thread=Main Thread, member=n/a): Loaded cache conf
iguration from "jar:file:/C:/Program%20Files/Oracle/coherence/3.5.2b463P2/lib/coherence.jar!/reports/report-group.xml"
I have tried every combination of classpath entries I can think of, and no matter what, it never shows an attempt to load the application-cache-config.xml supplied in the startup. Does anyone have any experience with something like this?

I guess your non-storing JAVA code does not specify -Dtangosol.pof.enabled=true and the -Dtangosol.pof.config =<POF file location> on joining the cluster. Post the startup java command and the complete logs.
If application-cache-config is not loaded then coherence-cache-config.xml should be loaded by default and set -Dtangosol.coherence.cacheconfig=<application-cache-config>

Can't setup PofAnnotationSerializer in pof-config.xml

Hi,
i have class annotated with @Portable and @PortableProperty, and pof-config.xml for setup serializer:
      <user-type>
         <type-id>1001</type-id>
         <class-name>entity.dto.base.EmployeeBaseDTO</class-name>
         <serializer>
            <class-name>com.tangosol.io.pof.PofAnnotationSerializer</class-name>
                <init-params>
                <init-param>
                    <param-type>int</param-type>
                    <param-value>1001</param-value>
                 </init-param>
                 <init-param>
                    <param-type>java.lang.Class</param-type>
                    <param-value>entity.dto.base.EmployeeBaseDTO</param-value>
                 </init-param>
              </init-params>
         </serializer>
      </user-type>
While starting Coherence 3.7.1 cluster, I get error:
Unable to instantiate PofSerializer class: com.tangosol.io.pof.PofAnnotationSerializer (Config=...\pof-config.xml, Type-Id=1001,
Class-Name=entity.dto.base.EmployeeBaseDTO))
java.lang.InstantiationException: Could not find a constructor for com.tangosol.io.pof.PofAnnotationSerializer(java.lang.Integer, com.tangosol.run.xml.SimpleElement)
Why second PofAnnotationSerializer contructor parameter is com.tangosol.run.xml.SimpleElement and not java.lang.Class ?
BTW setup PofAnnotationSerializer programatically works fine:
SimplePofContext pofCtx = new SimplePofContext();
int typeId = 1001;
pofCtx.registerUserType(typeId, EmployeeBaseDTO.class , new PofAnnotationSerializer<EmployeeBaseDTO>(typeId++, EmployeeBaseDTO.class, true));
Thanks,
L.V.

OK, so to enable auto indexing then yes, you need to specify the serializer in the POF configuration, as it says in the documentation 19.3.3 Enabling Automatic Indexing.
So in your case the configuration should look like this
      <user-type>
         <type-id>1001</type-id>
         <class-name>entity.dto.base.EmployeeBaseDTO</class-name>
         <serializer>
            <class-name>com.tangosol.io.pof.PofAnnotationSerializer</class-name>
                <init-params>
                <init-param>
                    <param-type>int</param-type>
                    <param-value>{type-id}</param-value>
                 </init-param>
                 <init-param>
                    <param-type>class</param-type>
                    <param-value>{class}</param-value>
                 </init-param>
                 <init-param>
                    <param-type>boolean</param-type>
                    <param-value>true</param-value>
                 </init-param>
              </init-params>
         </serializer>
      </user-type>
You do not replace the param-values that are inside { } or change the param-type values as these are macros that Coherence will automatically replace with the correct values.
Regarding your error, I'm not sure if that is related to your original question/issue.

Can I create different Coherence nodes in the same cluster with defferent?

Can I create different Coherence nodes in the same cluster with defferent cache-config.xml file ?
Can a cache be distributed in these deffirent nodes?

Yes. You can create different Coherence nodes in the same cluster with defferent cache-config.xml files as long as you use the same tangosol-coherence.xml file and the same tangosol-coherence-override.xml file. But you cannot store the cache data in the different nodes (started with different cache-config file). In other word, a node only create caches in their own's modes which are started with the same cache-config.xml file.
See the following demo:
I start a cache server using the cache config file examples-cache-server.xml. Then I start a storage-disabled cache console (cache client) using the cache config file coherence-cache-config.xml. Both of them using the same tangosol-coherence.xml file and the same tangosol-coherence-override.xml file.
The cache server uses a cache service PartitionedPofCache. But the client side is using the Distributedcache service. The cluster address is same 224.3.5.2.
The cluster name is also samme. They know each other.

Different distributed caches within the cluster

Hi,
i've three machines n1 , n2 and n3 respectively that host tangosol. 2 of them act as the primary distributed cache and the third one acts as the secondary cache. i also have weblogic running on n1 and based on some requests pumps data on to the distributed cache on n1 and n2. i've a listener configured on n1 and n2 and on the entry deleted event i would like to populate tangosol distributed service running on n3. all the 3 nodes are within the same cluster.
i would like to ensure that the data directly coming from weblogic should only be distributed across n1 and n2 and NOT n3. for e.g. i do not start an instance of tangosol on node n3. and an object gets pruned from either n1 or n2. so ideally i should get a storage not configured exception which does not happen.
The point is the moment is say CacheFactory.getCache("Dist:n3") in the cache listener, tangosol does populate the secondary cache by creating an instance of Dist:n3 on either n1 or n2 depending from where the object has been pruned.
from my understanding i dont think we can have a config file on n1 and n2 that does not have a scheme for n3. i tried doing that and got an illegalstate exception.
my next step was to define the Dist:n3 scheme on n1 and n2 with local storage false and have a similar config file on n3 with local-storage for Dist:n3 as true and local storage for the primary cache as false.
can i configure local-storage specific to a cache rather than to a node.
i also have an EJB deployed on weblogic that also entertains a getData request. i.e. this ejb will also check the primary cache and the secondary cache for data. i would have the statement
NamedCahe n3 = CacheFactory.getCache("n3") in the bean as well.

Hi Jigar,
i've three machines n1 , n2 and n3 respectively that
host tangosol. 2 of them act as the primary
distributed cache and the third one acts as the
secondary cache.First, I am curious as to the requirements that drive this configuration setup.
i would like to ensure that the data directly coming
from weblogic should only be distributed across n1
and n2 and NOT n3. for e.g. i do not start an
instance of tangosol on node n3. and an object gets
pruned from either n1 or n2. so ideally i should get
a storage not configured exception which does not
happen.
The point is the moment is say
CacheFactory.getCache("Dist:n3") in the cache
listener, tangosol does populate the secondary cache
by creating an instance of Dist:n3 on either n1 or n2
depending from where the object has been pruned.
from my understanding i dont think we can have a
config file on n1 and n2 that does not have a scheme
for n3. i tried doing that and got an illegalstate
exception.
my next step was to define the Dist:n3 scheme on n1
and n2 with local storage false and have a similar
config file on n3 with local-storage for Dist:n3 as
true and local storage for the primary cache as
false.
can i configure local-storage specific to a cache
rather than to a node.
i also have an EJB deployed on weblogic that also
entertains a getData request. i.e. this ejb will also
check the primary cache and the secondary cache for
data. i would have the statement
NamedCahe n3 = CacheFactory.getCache("n3") in the
bean as well.In this scenario, I would recommend having the "primary" and "secondary" caches on different cache services (i.e. distributed-scheme/service-name). Then you can configure local storage on a service by service basis (i.e. distributed-scheme/local-storage).

Daylight Savings Changes 2007

Daylight Savings time will be altered in 2007 as seen in http://geography.about.com/cs/daylightsavings/a/dst.htm
Is Coherence certified to handle these changes? We have already found issues in the OS and JDK that need to be patched.

Coherence will correctly handle daylight savings changes once the JDK has been patched.
Without the JDK patch, only the Coherence logging function will be incorrect, in that the logged messages will reflect the incorrect (unpatched) "timezone".
Coherence has very careful handling of "wall clock time" functionality to avoid being impacted by network time daemons, system clock irregularities, time zone shifts, etc.

Querying a collection object

I have an objects as follows
Entity {
key k;
Collection<Person> personList;
Person{
Address address;
Address{
String zipcode;
I want to get all the Entities coming under "zipcode=123456".
Please help me how to get it using the query.
TIA.

Hi,
One way might be to write a custom extractor that extends com.tangosol.util.extractor.AbstractExtractor and overrides extractFromEntry() to extract the collection of zip codes from a cached Entity (the value of the passed in Map.Entry). Then you could write a query using that extractor ...
ValueExtractor extractor = new CustomEntityZipExtractor();
Filter filter = new ContainsFilter(extractor, "123456");
Set entries = cache.entrySet(filter);Thanks

Hi Kevek,
I would strongly recommend starting with one of the working .NET examples shipped with Coherence for .NET. I think this will really help illustrate the basic tasks that must be done to get a C# application to interact with a remote Coherence NamedCache. The User Guide also contains step-by-step instructions on building each of the examples (ContactCache.Windows and ContactCache.Web).
Java serialization is tightly bound to the Java language and cannot be natively understood by a .NET application. This is exactly why we invented POF. It allows user types to be serialized in a language independent format so that C# applications can parse data sent by Java applications, and visa versa. Of course, to serialize and deserialize your user types to and from a POF stream, you need to use the POF APIs. There is no magic way of converting your Externalizable implementations to POF implementations.
Having said that, if you have implemented ExternalizableLite in your user types, you can use the com.tangosol.io.pof.PofOutputStream and com.tangosol.io.pof.PofInputStream classes to directly adapt your ExternalizableLite implementations to a POF implementation, but with some limitations (no schema evolution and other advanced POF features).
Regards,
Jason

Concurrent GC Behavior?

We are testing the use of Coherence in an 8 machine cluster where incoming requests can come to any node and get distributed by the invocable map interface to be updated on any other node in a distributed cache. When I set all 8 nodes to use concurrent GC and parallel collection (-Xmx1024m -Xms1024m -server -XX:+UseParNewGC -XX:+UseConcMarkSweepGC) the nodes have a 50-60% CPU overhead (x 2 cores means that more than 1 core is used by the process at all time!) except for the one node that gets few requests (it has about 30% CPU overhead).
Now the odd thing is this: I restarted one node using the classic GC behavior (just -Xmx1024m -Xms1024m -server) and... all the other nodes quickly dropped to almost zero CPU overhead, but that one node was at 50% CPU overhead. When I restarted it again with the parallel and concurrent GC settings, the other nodes picked up to 60% overhead (30% for the non-request node) and the restarted node hit 40% overhead. This is with a 32 bit Sun 1.5.0_11 vm on Linux.
I'm wondering what explains this behavior, how Tangosol responds to parallel and concurrent GC, and if there are guidelines for tuning GC that are particular to Tangosol. Also, this level of overhead does seem high to me, granting that the system hasn't been tuned yet. The servers are processing about 400 updates per second each, so about 3000 updates per second in total. What ballpark of CPU overhead on a modern Linux server would you expect to see?
Thanks,
Ron

I actually had already size limited the cache, with the maximum memory for the front of the distributed cache to 256 mb (i.e., the serialized data should be 1/4 of max heap size), using the simple disk spillover storage. A couple of other observations:
* when running all nodes with the concurrent collector, the system eventually settles down so that 1 core of 1 node is pegged and all other nodes are basically free. I've included a stack trace below
* We restarted our cluster yesterday and JMX data on that node shows:
- the one busy node has burned 19 hours 43 minutes of CPU.
- The ConcurrentMarkSweep collector has run 0 times using 0 seconds
- The ParNew collector has run 68000 times using 16 minutes
- The process heap has grown to 832 million bytes, less than the 1048 million byte maximum allowed, so it clearly isn't running out of memory
- Cache hits: 44000
- Cache misses: 36000
- Cache misses millis: 25
- Packets sent: 3.7 million
- PublisherSuccessRate: .9985
- ReceiverSuccessRate: .9990
- PacketPublisher Cpu 70126ms (0.1%)
Sometimes we see big spikes in network activity after a node goes up or down (e.g., we had 4 hours of 20 mb/s) but in this mode we are seeing extremely low network activity (basically no increase over the level we'd see without this process running)
Here's a sample thread dump on the busy node. Any idea why the CPU is pegged? The call to size() was a debugging call which we're removing to avoid any influence from that. We are seeing that these size calls aren't terminating, which itself is surprising to me.

Listening for new cachings getting created?

I'd like to be able to register my own MBeans on each distributed CacheServer for each cache that lives on that server. Is it possible to register a listener anywhere that gets called when a new cache gets created? Alternatively, is it possible to register a listener that is called after the cache factory has finished starting all the "autostart" caches?
I'm using version 3.3
thanks
sam
ps - I'm already registering my own custom global mbeans... but they are created before any of the caches get created.

Sam
You can specify your custom CacheFactory class in the override file so you can still use DefaultCacheServer
When I needed to intercept cache creation I extended DefaultConfigurableCacheFactory and overrode this method:
public NamedCache configureCache(CacheInfo cacheInfo, XmlElement xmlScheme, ClassLoader classLoader)
Then just call the super class version before or after doing whatever you need to.
The XML for the override file looks like this
<coherence>
     <configurable-cache-factory-config>
          <class-name>com.oracle.coherence.common.configuration.AdvancedConfigurableCacheFactory</class-name>
          <init-params>
               <init-param>
                      <param-type>java.lang.String</param-type>
                      <param-value system-property="tangosol.coherence.cacheconfig">coherence-cache-config.xml</param-value>
               </init-param>
          </init-params>
     </configurable-cache-factory-config>
</coherence>The above snippet is taken from the Incubator common library. You would replace com.oracle.coherence.common.configuration.AdvancedConfigurableCacheFactory with the name of your class.
You need to call the override file tangosol-coherence-override.xml and put it on the class path or if you call it anything else then specify the name as a JVM argument with -Dtangosol.coherence.override=<name of your file>

How to get Oracle Coherence caching running within CQ5

I've been trying to get Oracle Coherence running within CQ5 and I'm having problems with the setup. First, I've been successful in creating an OSGi bundle jar from coherence.jar and it does deploy successfully through the Felix OSGi console. But when I try to execute code using the Coherence classes, I get RMI marshalling run-time errors. I've resolved the other run-time errors that have to do with the Import-Package definition in manifest.mf for the bundle. I believe that the root problem that I'm facing is the deployment of the files tangosol-coherence-override.xml and the additional xml file that it points to. I don't believe that these two files are being found within CQ5 correctly. I've tried placing these files in the following locations:
1. Within coherence.jar itself (at the root directory)
2. In the CQ5 application's install folder
3. In the CQ5 application's src/main/resources folder
Has anyone ever deployed Oracle Coherence in CQ5 or can give me a suggestion on what to try? I appreciate any help or ideas.
Thanks! - Charlie

There are 3 options which is described below. The steps may slightly vary based on cq & Oracle Coherence version. The details mentioned below are for cq5.4 & Coherence 3.7.1
Option 1:- Oracle recommended way
*     Create a basic Web application directory
/Sample.jsp
/WEB-INF/web.xml
/WEB-INF/classes/tangosol-coherence-override.xml
/WEB-INF/lib/coherence.jar
*     jar -cvf hello.war *
*     Deploy the hello.war file by going to cq servlet engine at http://<host>:<port>/admin
*     Access your sample with http://<host>:<port>/<contextroot>/Sample.jsp
Option 2:- Combination of Option 1 & Option 3
*      Stop the cq
*      Place coherence.jar at <CQ_Install_Dir>/crx-quickstart/server/runtime/0/_/WEB-INF/lib/
*      Place tangosol-coherence-override.xml and all additional xml files at <CQ_Install_Dir>/crx-quickstart/server/runtime/0/_/WEB-INF/classes/
*      Modify <CQ_Install_Dir>/crx-quickstart/launchpad/sling.properties to add below properties
sling.bootdelegation.com.tangosol.net.cache=com.tangosol.net.cache
sling.bootdelegation.com.tangosol.net=com.tangosol.net
sling.bootdelegation.com.tangosol.util=com.tangosol.util
*       Start the cq
*       Verify jsp script etc... by putting into cache.. Same thing like
        <%
            String key = "k2";
            String value = "Hello World from cq!";
ClassLoader oldLoader = Thread.currentThread().getContextClassLoader();
ClassLoader newLoader = com.tangosol.net.CacheFactory.class.getClassLoader();
Thread.currentThread().setContextClassLoader(newLoader);
            CacheFactory.ensureCluster();
            NamedCache cache = CacheFactory.getCache("hello-example");
            cache.put(key, value);
            out.println((String)cache.get(key));
            CacheFactory.shutdown();
Thread.currentThread().setContextClassLoader(oldLoader);
         %>
Option 3 :-   The one you are trying by creating an OSGi bundle jar from coherence.jar & prefeerd approach also. I haven't tried this approach but just throughing some thaughts.
*    From some of oracle seminors I remembered oracle had a plans to have OSGi jar for Coherence. Try to get that instead of building the one ourself.
*    If it is not available then Looking at your problem as a workaround i can think of is try with putting the XML file in the repository & load xml in java class something like as
getClass().getClassLoader().getResourceAsStream("tangosol-coherence-override.xml")

          Tangosol Coherence: Clustered Replicated Cache for Weblogic


Warning: I upgraded a couple hours ago here in CA and things aren't exactly happening.
Maybe it's just my set-up here (OS X 10.4.10) but I'm scrambling to get the phone to work again without a restore to the old iPhone version. (I synced up before the upgrade so have all settings etc except a large number of pix which will be erased with restore).
What? After upgrading to v1.1.2 (via iTunes) the phone now only allows an "Emergency call" option, as displayed on iPhone's default slide to unlock screen as well as the only functional screen to follow - above the numbers keypad (rotating in other languages as "Appel d'urgence" and "Notruf"). "No service" is also new with the upgrade so any "Emergency call" option is also null and void.
In other words - back up all photos and movies from the phone as well as sync up with your MAC before upgrading to v1.1.2 and if anyone has any tips on how to restore without losing photos please hit me back.
Thanks.

Design question about Coherence as a event source

Hi Guys,
could you please help me with designing the following use case in the CEP way?
I have a Coherence cluster with several types of objects. Each object has its state. I would like to generate a specific warning event whenever the state of the object in Coherence has not changed in specific amount of time and store it back into Coherence (different named cache).
Is this something that can be implemented in CEP? How the flow in CEP would look like?
Kind Regards,
Martin

Martin,
You need to write a class that implements com.tangosol.util.MapListener interface and use that as a <wlevs:cache-listener> to the cache you configure in CEP spring file. The class must also be an event source, which sends insert events for cache update and insert events from Coherence (entryInserted, entryUpdated). These events must be sent to a downstream processor which has a non-event detection query configured. You can find more info for writing such a query at http://download.oracle.com/docs/cd/E14571_01/apirefs.1111/e12048/pattern_recog.htm.
Hope that helps,
Manju.
