Talend Studio: Set a JVM property for all the Jobs executed by a JobServer on Windows / Linux

[TalendSolutionExpert]

In some cases, it is necessary to set a JVM property, for example -Dfile.encoding=UTF-8, for all Jobs executed by a JobServer.

Resolution

For the JobServer Windows Service created by the installer:

1. Edit the wrapper.conf file located in the folder \jobserver\TalendServices\conf, and add the line:

   wrapper.app.env._JAVA_OPTIONS=-Dfile.encoding=UTF-8

   Under the paragraph:

   #*******************************************************************
   # Application environment properties.
   #*******************************************************************
   # Adds an environment to the application

   Example:

   #*******************************************************************
   # Application environment properties.
   #*******************************************************************
   # Adds an environment to the application
   wrapper.app.env._JAVA_OPTIONS=-Dfile.encoding=UTF-8

2. Restart the JobServer.

For a JobServer created with jsl_static64.exe:

1. In the jsl_static64.ini file, add the following to the beginning of the file:

   [defines]
   _JAVA_OPTIONS=-Dfile.encoding=UTF-8
   export=_JAVA_OPTIONS

2. Restart the JobServer.

For a JobServer running on Linux:

Service:
      Edit the /etc/systemd/system/talend-rjs*.service
      Add:
       Environment=_JAVA_OPTIONS=-Duser.timezone=Europe/Berlin
      systemctl daemon-reload
      stop / start jobserver  Manual:
  	Option 1, for all users:
  		Edit /etc/profile (see: https://unix.stackexchange.com/a/151735/239457 )
  	Option 2, for specific user:
  		Edit ~/.bashrc  	Add: _JAVA_OPTIONS='-Duser.timezone=Europe/Vienna'
  	Add: export _JAVA_OPTIONS
  	Log OUT, start a new shell.
  	Start talend jobserver (nohup / screen / etc)

Verify:

After starting the job we will see:

    Starting job hello_world at 11:12 29/01/2020.
    Picked up _JAVA_OPTIONS: -Duser.timezone=Europe/Berlin
