Output destination

When the target is a J2EE server

• In Windows
  working-directory^#\ejb\server-name\javacore*.txt
  
• In UNIX
  working-directory^#/ejb/server-name/javacore*.txt
  

# The working-directory indicates a directory specified in the user definition of a J2EE server (ejb.public.directory in the usrconf.cfg file). The default values are as follows:

• In Windows
  Cosminexus-installation-directory\CC\server\public
  
• In UNIX
  /opt/Cosminexus/CC/server/public
  

When the target is a SFO server

• In Windows
  Cosminexus-installation-directory\CC\server\public\ejb\server-name\javacore*.txt
  
• In UNIX
  /opt/Cosminexus/CC/server/public/ejb/server-name/javacore*.txt
  

When the target is a CORBA naming service and CMT

• In Windows
  Cosminexus-installation-directory\TPB\logj\javacore*.txt
  
• In UNIX
  /opt/Cosminexus/TPB/logj/javacore*.txt
