Re: How to enable a event during a shutdown and start up ofservicemix-component

Hi Ganesh,

You can setup the ActiveMQ embedded in ServiceMix to persist current message exchanges in transit.

To do it, in the conf/activemq.xml, you can setup the persistenceAdapter :

 <amq:persistenceAdapter>
      <amq:journaledJDBC journalLogFiles="5" dataDirectory="/<shared>/data/amq"/>
 </amq:persistenceAdapter>

This configuration uses a Derby embedded database (file based), but you can setup persistence adapter on another database (like 
Oracle) :

<amq:persistenceAdapter>
      <amq:jdbcPersistenceAdapter dataSource="#oracle-ds" /> 
</amq:persistenceAdapter>

<bean id="oracle-ds" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
 	 <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> 
  <property name="url" value="jdbc:oracle:thin:@192.168.1.4:1521:mydbname" /> 
  <property name="username" value="smix_node1_ha" /> 
  <property name="password" value="smix_node1_ha" /> 
  <property name="poolPreparedStatements" value="true" /> 
</bean>

However, this configuration will persist message exchanges : if you shutdown your component or your SMX instance, the exchanges 
will be stored and when the component or SMX instance will start again, the exchanges will be reinjected in.

What kind of data do you want to store during a component shutdown ?

JB

Re: How to enable a event during a shutdown and start up ofservicemix-component

[navigator09 <ga...@gmail.com>]

Hi JB,


  I am trying to persist contents of datastructure defined inside
servicemix-camel component. The vector contains information about submitted
jobs. So before the servicemix camel component goes down the data inside
datastructure needs to be persisted. when the component starts up again, the
data structure has to be filled in with the persisted data, so that polling
for the jobs can continue. How do I do this?

Regards,
Ganesh
