Sure, assign a specific path to your monitor resource and let each node symlink this to local version to use, eg. use /opt/IBM/ITM_A/tmp/current/kddsignl in MonitorProcess and then make ''ln -s /opt/IBM/ITM_A/<local version> /opt/IBM/ITM_A/current" where <local version> equals either tmp/dbkrmtna41_or_AIS1DEQ2 or tmp/dbkrmtna42_or_AIS1DEQ2

That's another way, use a wrapper script that figure out on which node it's executing and then use the right version. But I'll prefer using the 'current' symlink over this IMhO :) _______________________________________________ Veritas-ha maillist - Veritas-ha@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-ha
