With the EADs session failover functionality, pass the root AP information generated on the J2EE server to EADs clients. By considering root AP information as a key, you can compare the performance analysis trace output by a J2EE server, communication trace log of the EADs client, and performance analysis trace of the EADs server, and track a series of access to the EADs server for which the EADs session failover functionality was a starting point.

Root AP information is output to the output performance analysis trace or communication trace log in the following order:

1. The EADs session failover functionality outputs the performance analysis trace
2. The EADs client outputs the communication trace log
3. The EADs server outputs the performance analysis trace
