% source /<install_path>/<version>/<platform>/etc/vovrc.csh
% vovsh -x 'vtk_generic_get project info; puts $info(product)'If vovserver loses a feature, it will keep running for a grace period of five days.
If the vovserver fails to get the appropriate license upon startup, or if the grace period expires, it will go into "License Violation", which essentially means that dispatching to remote taskers is disabled. Every other behavior remains fully functional.
