3.12 Deploying a process for the output of the performance analysis trace file

This section describes the deployment of a program that outputs the performance analysis trace file. This process must be deployed always on the Application Server system. Make sure that you deploy the process on the Application Server machine. You may or may not deploy the process on the EJB client machine.

The performance analysis trace file is output by the PRF daemon (performance tracer).

Organization of this section
(1) Features of the system configuration
(2) Required software and the processes to be invoked on the respective machines

(1) Features of the system configuration

Deploy the PRF daemon on a machine with Application Server and the EJB client application running.

The following figure shows an example of deploying the PRF daemon:

Note: For other legend items, see 3.2 Description of the system configuration.

Features
  • The trace file for analyzing the system performance can be output.
  • The trace file can be used for identifying the points where error has occurred.
Mechanism to output the performance analysis trace
When a request is processed between the client and the server, each functionality layer of Application Server or the EJB client application outputs the performance analysis information in a buffer. The PRF daemon outputs this trace information in the files of each machine. You can use Management Server to collect the trace information output in the files.

(2) Required software and the processes to be invoked on the respective machines

Invoke the following process to output the performance analysis trace file:

The other required software and the processes to be invoked in Application Server are different for each system configuration, depending on the functionality used. Deploy the required software and processes as per the functionality used.
