Enabling Checkpointing

The following sections describe how to enable SFSB checkpointing:

• Server Instance and EJB Container Levels

• Application and EJB Module Levels

• SFSB Level

Server Instance and EJB Container Levels

To enable SFSB checkpointing at the server instance or EJB container level, see Choosing a Persistence Store.

Application and EJB Module Levels

To enable SFSB checkpointing at the application or EJB module level during deployment, use the asadmin deploy or asadmin deploydir command with the --availabilityenabled option set to true. For details, see the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Reference Manual.

SFSB Level

To enable SFSB checkpointing at the SFSB level, set availability-enabled="true" in the ejb element of the SFSB’s sun-ejb-jar.xml file as follows:

<sun-ejb-jar>
   ...
   <enterprise-beans>
      ...
      <ejb availability-enabled="true">
         <ejb-name>MySFSB</ejb-name>
      </ejb>
   ...
   </enterprise-beans>
</sun-ejb-jar>
