You can use properties files to create or change trace
service properties and the associated trace log under a server.
Before you begin
Determine the changes that you want to make to your trace
service configuration or its configuration objects.
Start the
wsadmin scripting tool. To start wsadmin using the Jython language,
run the wsadmin -lang jython command from the bin directory
of the server profile.
Note: 這個主題參照一或多個應用程式伺服器日誌檔。
此外,在分散式和 IBM® i 系統上,另外也建議您可以配置伺服器來使用「高效能可延伸記載 (HPEL)」日誌和追蹤基礎架構,而不使用 SystemOut.log、SystemErr.log, trace.log 及 activity.log 檔案。HPEL 與原生 z/OS® 記載機能也可以一起使用。如果您使用 HPEL,則可以從伺服器設定檔 bin 目錄,利用 LogViewer 指令行工具來存取您所有的日誌和追蹤資訊。請參閱有關利用 HPEL 疑難排解應用程式的資訊,以取得更多使用 HPEL 的相關資訊。
About this task
Using a properties file, you can create, modify, or delete
a trace service object and its configuration properties.
Run
administrative commands using wsadmin to change a properties file
for a trace service, validate the properties, and apply them to your
configuration.
Table 1. Actions

Specify the properties to delete in the properties
file and then run the deleteConfigProperties command. |
Optionally, you can use interactive mode with the commands:
AdminTask.command_name('-interactive')
Procedure
- Create trace service properties.
- Specify TraceService properties in a properties file.
Open an editor and specify trace service properties and an
associated TraceLog under a server in a properties file. You can copy
the following example properties into an editor and modify the properties
as needed for your situation. The example shows a property under TraceService
with name myName and value myVal.

- Run the applyConfigProperties command
to create a TraceService configuration.
Running the applyConfigProperties command
applies the properties file to the configuration. In this Jython example,
the optional -reportFileName parameter produces a
report named report.txt:
AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt'])
- Modify existing trace service or associated TraceLog properties.
- Obtain a properties file for the trace service that
you want to change.
You can extract a properties file
for a TraceService using the extractConfigProperties command.
- Open the properties file in an editor and change the
properties as needed.
Ensure that the environment variables
in the properties file match your system.
- Run the applyConfigProperties command.
- Delete the trace service properties.
To delete
one or more properties, specify only those properties to delete in
the properties file and run deleteConfigProperties.
AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')
Results
You can use the properties file to configure and manage
the trace service object.
What to do next
Save the changes to your configuration.
