Depending on specific customer requirements and how the ROB-EX Scheduler system is deployed, it may be needed to further configure more advanced startup parameters of the ROB-EX Scheduler Multiuser Server service.

The service for production will be running as a Windows background service and the parameters are passed through to the service startup phase through entries in the Windows registry database.

  • Edit existing service settings using the Windows Regedit tool (Run->Regedit.exe). Note this is an advanced editing tool – only proceed if you know what you are doing.
  • Search for the node HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\ROB-EXServerG2Instance1x64\Parameters.
    • The Instance id may be different if multiple ROB-EX Scheduler Multiuser Server are installed on the same server. It will be a number from 1 and up and is assigned during installation (see Running multiple instances)
  • Edit the setting in questions by double clicking on the relevant row in the Parameter cell. This will open an editor. See detailed overview of frequently used settings in the table below.
  • Close the editor window by clicking OK
  • Close Regedit and restart the server service using the Windows Services manager (Run->services.msc). Also see Starting and stopping ROB-EX Server.

Frequently used settings

Regedit sub-folder Parameter Description
Java JvmMx Specify the maximum number of mega bytes memory the service client may grow to. The default value is 2000MB but for sites with a high number of objects (Production Orders, Operations, Materials, BOM-lines), or in case log-files contains OutOfMemoryException messages, increase this value to as an example 3000MB. Note the editor for this value by default show the value as a Hex number – switch to Decimal representation for easier interpretation of the value.
