How many concurrent jobs can I run on a single harvest agent?
Our experience with fairly modern, x86-based PCs, running any more than 5 concurrent harvests on a single (dedicated) machine is probably too many (but this will depend on the JVM memory settings). We usually limit ourselves to two concurrent harvests on machines that are shared with other applications. If you need more concurrent harvests, just add additional servers running as harvest agents. You can have as many harvest agents as you have spare hardware. We are using the CATALINA_OPTS=”-server -Dcom.sun.management.jmxremote.port=9004″ option (and we are using jconsole to monitor our tomcat installs) but why is this necessary for running WCT when its only used for remote monitoring (which is great but not necessary for running apps out of tomcat)? The CATALINA_OPTS=”-server -Dcom.sun.management.jmxremote.port=9004 setting should only be required on tomcat instances that are running as a harvest agent. The Heritix harvester needs to register its objects with JMX to function properly.
