15.5.1 Trace collection point

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.

Organization of this subsection

(1) Trace collection during the startup and termination of the J2EE server
(2) Trace collection in each function layer
(3) Trace collection during the startup and termination of application methods
(4) Return codes for each trace

(1) 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 on trace collection when a J2EE server starts or terminates, see 8.22 Trace collection points when a J2EE server is started or terminated in the manual uCosminexus Application Server Maintenance and Migration Guide.

(2) Trace collection in each function layer

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

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

Figure 15‒2: Function layers and trace collection points (in the case of Web client configuration)

Figure 15‒3: Function layers and trace collection points (in the case of a system for executing batch applications)

Figure 15‒4: Function layers and trace collection points (in the case of EJB client, TPBroker client, or TPBroker OTM client configuration (CTM usage))

Figure 15‒5: 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 15-6.

Reference note

Apart from the function layers described in Table 15-6, 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 15-6 for which the PRF trace can be collected, and their event IDs.

(3) 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 trace information, see 8.23 Trace collection points of an application in the uCosminexus Application Server Maintenance and Migration Guide.

(4) 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
