In a number of situations it is recommended or required to set Java options to specify the behavior of the JVM.
- Recommendations: JS7 - FAQ - Which Java Options are recommended?
- Troubleshooting: JS7 - Troubleshooting - Connection reset or Timeout reached (30s) for process and other articles.
Java options are set individually for the respective JS7 componentsproducts, the Controller, Agent and JOC Cockpit.

directory of the installation run- for a Controller:
js7_controller_<controller-id>w.exe
- where
<controller-id>
corresponds to the Controller ID the Controller has been installed with. - Example:
C:\Program Files\sos-berlin.com\js7\controller\my-controller\service\js7_controller_mycontrollerw.exe
- where
- for an Agent:
js7_agent_<port>w.exe

<port>
corresponds to the port that the Agent is operated with. - Example:
C:\Program Files\sos-berlin.com\js7\agent_4445\service\js7_agent_4445w.exe

When running the JOC Cockpit as a daemon then the following line can be added to the
$HOME/.jocrc
file of the JOC Cockpit run-time account. This file is created by the installer and it is used if it exists and is executable. The$HOME
directory is identified from the/etc/passwd
file during installation.
