Shutdown class in cluster env.

Question

I have a shutdown class that basically cleans up some data from
          database. In clustering env., obviously, I don't
          want the cleanup to happen unless all my WL servers in the cluster are
          shutdown, can someone tell me how can
          I achieve this? thanks

Startup/Shutdown Class will be available in 9.0.4.
However you can use a work around in 9.0.2/9.0.3 to simulate the Startup/Shutdown class:
Following are the steps required to achieve this functionality:
1) Write and compile your startup class as an application client. This class must contain a main method that will be called by OC4J during startup.
2) Create a META-INF/Manifest.mf file for the application-client, for example
Manifest-Version: 1.0
Main-Class: Oracle9iASStartup
3) Create a deployment descriptor for the application client as follows:
<application-client>
<display-name>Oracle9iASStartup</display-name>
</application-client>
4) Create the application-client jar file for your startup class with the above Manifest and deployment descriptor.
5) Create an EAR file for the application-client module with the an OC4J-specific deployment descriptor orion-application.xml as follows:
<orion-application>
<client-module path="startup-class-client.jar" auto-start="true" user="anonymous" />
</orion-application>
Build your EAR and deploy your application with auto-start set to "true".
