The trace collection points are broadly classified into trace collection during the startup and termination of a J2EE server, trace collection during processing in each function layer, and trace collection during the startup and termination of application methods.

Trace collection during the startup and termination of the J2EE server

The trace information can be collected when the startup processing of the J2EE server ends, and when the termination processing of the J2EE server starts. The event IDs that can be acquired, and the references are as follows:

• Event ID
  0x8FFE to 0x8FFF
  
• Reference
  For details about trace collections during the startup and termination of the J2EE server, see 8.27 Trace collection points when a J2EE server is started or terminated.
  

Trace collection in each function layer

The following table describes the correspondence between the event IDs that can be acquired and the function layers.

Corresponds to the numbers in Figure 8-1 through Figure 8-4.

The following figures show the function layers for which the PRF trace is output, and the trace collection points for each system configuration.

Figure 8-1 Function layers and trace collection points (in the case of Web client configuration)

Figure 8-2 Function layers and trace collection points (in the case of a system for executing batch applications)

Figure 8-3 Function layers and trace collection points (in the case of EJB client, TPBroker client, or TPBroker OTM client configuration (CTM usage))

Figure 8-4 Functionality layers and trace collection points (In the TP1 inbound integrated function)

The trace collection points are divided in detail in each function layer, and the PRF trace collection level differs depending on the trace collection point. For details about trace collection points of each function layer, and the PRF trace collection level, see the references described in Table 8-2.

Reference note

Apart from the function layers described in Table 8-2, the PRF trace can be collected for some Application Server processes, component software, and related programs as well.

The following table describes the correspondence between the function layers other than those described in Table 8-2 for which the PRF trace can be collected, and their event IDs.

Trace collection during the startup and termination of application methods

You can collect the trace information when an application method starts and terminates. The trace information that you can collect is as follows:

• Method start and termination time
• Identity ID
• Package name, class name, method name
• Line number of the last line executed by the method
• Class name of the exception or error that occurs

For details on the trace information, see 8.28 Trace collection points of an application.

Return codes for each trace

For an entrance trace, the return code of each trace is always output as 0.

For an exit trace and the trace after invocation, the return codes are output as follows:

Normal termination: 0

Abnormal termination: Other than 0

In the trace based performance analysis, you can specify the following four types of PRF trace collection levels to output the trace. The number of trace collection points differs depending upon the PRF trace level used. For details about the trace collection points, and PRF trace collection levels, see the references described in Table 8-2.

• Standard level
  Output the trace information that can identify the boundaries (entrance and exit) of each function layer.
  
• Advanced level
  Output the trace information of processes in every function layer, in addition to the output contents of the standard level.
  
• Maintenance level
  This is the level for acquiring the maintenance information required when a failure occurs.
  
• Prevention level
  This is the level for preventing the output of trace information. This level can be set up only in the RMI function layer.
  

When the operation is performed by using the Management Server, the trace information is output by setting up a common level for all function layers, in the Easy Setup definition file.

In the next sections, the trace collection points for the trace collection levels Standard and Advanced are described. Because the Maintenance level is the level for collecting maintenance information, such as when a failure occurs, the information for this level need not usually be collected.
