coherence adapter to work with external remote cache

coherence adapter to work with external remote cache

I have followed the exact steps given in the URL below to make the coherence adapter to work with external remote cache

https://docs.oracle.com/cd/E15357_01/coh.360/e15726/gs_example.htm

1. create a file

example-config.xml

++

<?xml version="1.0"?>

<!DOCTYPE cache-config SYSTEM "cache-config.dtd">

<cache-config>

  <caching-scheme-mapping>

     <cache-mapping>

        <cache-name>dist-extend</cache-name>

        <scheme-name>extend</scheme-name>

     </cache-mapping>

  </caching-scheme-mapping>

  <caching-schemes>

     <distributed-scheme>

        <scheme-name>extend</scheme-name>

        <lease-granularity>member</lease-granularity>

        <backing-map-scheme>

           <local-scheme/>

        </backing-map-scheme>

        <autostart>true</autostart>

     </distributed-scheme>

     <proxy-scheme>

        <service-name>ExtendTcpProxyService</service-name>

        <thread-count>5</thread-count>

        <acceptor-config>

           <tcp-acceptor>

              <local-address>

                 <address>localhost</address>

                 <port>9099</port>

              </local-address>

           </tcp-acceptor>

        </acceptor-config>

        <autostart>true</autostart>

     </proxy-scheme>

  </caching-schemes>

</cache-config>

++

2. Create a file

extend-config.xml

++

<?xml version="1.0"?>

<!DOCTYPE cache-config SYSTEM "cache-config.dtd">

<cache-config>

 <caching-scheme-mapping>

   <cache-mapping>

     <cache-name>dist-extend</cache-name>

     <scheme-name>remote</scheme-name>

   </cache-mapping>

 </caching-scheme-mapping>

 <caching-schemes>

   <remote-cache-scheme>

     <scheme-name>remote</scheme-name>

     <service-name>ExtendTcpCacheService</service-name>

     <initiator-config>

       <tcp-initiator>

         <remote-addresses>

           <socket-address>

             <address>localhost</address>

             <port>9099</port>

           </socket-address>

         </remote-addresses>

         <connect-timeout>10s</connect-timeout>

       </tcp-initiator>

       <outgoing-message-handler>

         <request-timeout>5s</request-timeout>

       </outgoing-message-handler>

     </initiator-config>

   </remote-cache-scheme>

   <remote-invocation-scheme>

     <scheme-name>extend-invocation</scheme-name>

     <service-name>ExtendTcpInvocationService</service-name>

     <initiator-config>

       <tcp-initiator>

         <remote-addresses>

           <socket-address>

             <address>localhost</address>

             <port>9099</port>

           </socket-address>

         </remote-addresses>

         <connect-timeout>10s</connect-timeout>

       </tcp-initiator>

       <outgoing-message-handler>

         <request-timeout>5s</request-timeout>

       </outgoing-message-handler>

     </initiator-config>

   </remote-invocation-scheme>

 </caching-schemes>

</cache-config>

3. Run the external coherence server using the command

java -cp /fmw11g/soa12212/coherence/lib/coherence.jar:. -Dtangosol.coherence.cacheconfig=example-config.xml com.tangosol.net.DefaultCacheServer

4. Modify the Outbound Connection Pool Configuration Table for

eis/Coherence/Remote

with the following

CacheConfigLocation java.lang.String /home/oracle/extend-config.xml

ClassLoaderMode java.lang.String CUSTOM

ConnectionFactoryLocation java.lang.String <blank>

PojoJarFile java.lang.String <blank>

ServiceName java.lang.String  <blank>

WLSExtendProxy java.lang.Boolean false

Here blank means no value.

5. Deploy the SOA Project ,

extract the project Cohe1.zip and deploy the coherence soa project.

Refer to the uploaded file Cohe1.zip

6. Run the BPELProcess1 with the input as say TEST1234567890 ,

on successful execution this creates a cache entry with the key as test1 and value as "TEST1234567890".

Check the flow trace , if everything goes well this you should see no error's.

Now run BPELProcess2 , give input as any random value , this reads coherence with the key name as "test1" and get's the value for the key "test1".

Successful execution should give the result as "TEST1234567890"
