If you install the IBM Docs Conversion Server on a Linux environment as described in this article, it could be that the Symphony tasks will not start. In the error log file (/opt/IBM/ConnectionsDocs/Conversion/symphony/sym_monitor/error.log) you will see an error message that the XWindows system could not be startet:
/opt/IBM/ConnectionsDocs/Conversion/symphony/inst7/ibm_lotus_symphony2/program/soffice.bin X11 error: Can’t open display: :0 Set DISPLAY environment variable, use -display option or check permissions of your X-Server (See “man X” resp. “man xhost” for details)
In this case you need to add the parameter “-headless” to the template file “/opt/IBM/ConnectionsDocs/Conversion/symphony/sym_monitor/template.sh” so that it then looks like that:
$1 -headless -invisible -conversionmode -hidemenu -nofirststartwizard "-accept=socket,host=0.0.0.0,port=${2};urp;StarOffice.ServiceManager" & After that, reboot the machine and then the Symphony soffice tasks should be running.
