OPMN and process monitoring

Synopsis: OPMN and process monitoring - This article will outline the methods by which OPMN manages OC4J containers and the HTTP Server instances. The communication between the Process Manager and the OC4J containers and the HTTP Server instances will be outlined wherein death detection and restart will form part of OPMN's responsibilities. Tuning OC4J containers' heap requirements will highlight the activity of the GC thread that might make full GC scans anytime during the lifetime of the container. The efficiencies introduced by making the containers redundant will also be discussed.
