    Coherence cache server start up issue

    974632
      Hi ,

      Coherence is able to resolve my Spring bean. However I see the following repeatedly when DCS starts up (see highlighted part below). The cache configuration is read repeatedly from my coherence-cache-config.xml in the application. I have tried renaming this file as well. Still does not work.

      Need suggestions to resolve this issue urgently. Thanks.

          Hi,

          Without seeing the config it is hard to say for certain what is going on. Do you have some dependency in your Spring Bean so that when it is constructed it is calling into CacheFactory. This could cause it to go into a never ending loop as the CacheFactory has not finished being initialised when the Spring bean gets created.

            Hi,

            Thanks for the response.

            Please find some of the config file snippets below:

            I have the following in my spring config file - applicationContext-beans.xml:
                 <bean id="myCacheBean"
                 class="com.tangosol.coherence.hibernate.HibernateCacheStore"
                 scope="prototype">
                 <property name="sessionFactory" ref="sessionFactory" />
                 </bean>


            tangosol-coherence-override.xml - (I am using coherence-cache-config.xml which is the default name):
                 <configurable-cache-factory-config>
                      <class-name system-property="tangosol.coherence.cachefactory">
                           com.tangosol.coherence.spring.SpringAwareCacheFactory
                      </class-name>
                      <init-params>
                           <init-param id="1">
                      <param-type>java.lang.String</param-type>
                      <param-value system-property="tangosol.coherence.springconfig">applicationContext-beans.xml</param-value>
                           </init-param>
                      </init-params>
                 </configurable-cache-factory-config>


            coherence-cache-config.xml:

                      <cache-mapping>
                           <cache-name>myCache</cache-name>
                           <scheme-name>replicated-db-backed</scheme-name>
                      </cache-mapping>

                      <replicated-scheme>
                           <scheme-name>replicated-db-backed</scheme-name>
                           <service-name>ReplicatedCache</service-name>

                           <read-write-backing-map-scheme>
                 <internal-cache-scheme>
                 <local-scheme></local-scheme>
                 </internal-cache-scheme>     
                           <cachestore-scheme>
                                     <scheme-name>myCacheScheme</scheme-name>
                      <class-scheme>
                      <class-name>
                      spring-bean:myCacheBean
                      </class-name>
                           <init-param>
                                               <param-name>setEntityName</param-name>
                                               <param-value>myCache</param-value>
                                          </init-param>
                      </class-scheme>
                      </cachestore-scheme>     
                      
                      
                                </read-write-backing-map-scheme>
                           </backing-map-scheme>
                           
                      </replicated-scheme>


            Am I missing something or is something wrong in the configuration above. Appreciate any pointers, Thanks in advance.

              Also, I see

              INFO: Initializing Spring root WebApplicationContext

              printed first and then the above Coherence DCS output. Looks like Spring comes into picture first, As per your suggestion it does look like its going to indefinite loop waiting for
              com.tangosol.coherence.spring.SpringAwareCacheFactory to be initialized?
              Can you please suggest how to get rid of this problem? Thanks.
