With the EADs session failover functionality, global session information is stored in the EADs server cache. Hence, you cannot destroy an HTTP session with stopping the J2EE application or the J2EE sever. Destroy an HTTP session by deleting global session information from the EADs server cache.

Execute the following procedures for deleting global session information:

1. Stop the J2EE applications or J2EE server.
   Stop all J2EE applications including other replicated J2EE applications or all J2EE servers.
   
2. Delete global session information stored in a cache on the EADs server.
   Use the cjezclearsession command and delete global session information stored in a cache on the EADs server. For details on the procedures for deleting global session information, see 7.8.1 Deleting global session information on an EADs server (session information storage destination server) .
   
3. Start the J2EE application.
