The system log of an EJB client application is output in each process of the EJB client application. In the system log, you can share the log output destination subdirectory among the multiple processes. The operation mode for sharing the log output destination subdirectory among the multiple processes is called the shared subdirectory mode.

Hint

If you want to use an existing EJB client application created with a version earlier than 06-50 as it is, perform the operation in the exclusive subdirectory mode in which the log output destination subdirectory is created for each process. We recommend that you use the shared subdirectory mode for creating a new EJB client application because the exclusive subdirectory mode is used for compatibility with versions earlier than 06-50.

The following table describes operations in the shared subdirectory mode.

Default value of the ejbserver.client.log.appid key#	Ejbcl
Specification of the ejbserver.client.log.directorynum key#	Always disabled.
Number of files that can be specified in the ejbserver.logger.channels.define.channel-name.filenum key#	1 to 64

System property specified when an EJB client application is started.

Note

• When executing an EJB client application with the cjclstartap command, use the shared subdirectory mode.
• When using the user log functionality of an EJB client application, use the shared subdirectory mode.

• Specifying the operation mode
  For details on specifying the class path for using the shared subdirectory mode, see 3.7.4 Specifying JAR files in the class path of the EJB client application.
  
• Sharing a subdirectory
  When you are using the shared subdirectory mode, you can share the log output destination subdirectory. For details on sharing a subdirectory, see 3.8.4 Sharing the log output destination subdirectory among multiple processes.
