Use this guided activity to define health policies to detect and manage health conditions in your environment.

The conditions fall roughly into four categories: memory leaks, hung servers, preventative restarts, and storm drains. <br/><br/> <strong>Tip:</strong> It is recommended that you create high-level policies in supervised mode to widely monitor for health conditions. Once a problem has been identified in a particular application, server members can have more specific health policies applied to them in automatic mode to maintain availability until the issue can be fully resolved. <br/><br/> For more information: <br/> <IMG SRC="../com.ibm.ws.console.guidedactivity/images/topic.gif" border="0" alt="Online task documentation" align="absmiddle"/> <A target="help" HREF="http://www14.software.ibm.com/webapp/wsbroker/redirect?version=phil&product=was-nd-dist&topic=twve_odhealthpolicy"> Creating the health policy</A> <br/> <IMG SRC="../com.ibm.ws.console.guidedactivity/images/command_prompt.gif" border="0" alt="Online task documentation" align="absmiddle"/> <a target="help" href="http://www14.software.ibm.com/webapp/wsbroker/redirect?version=phil&product=was-nd-dist&topic=rwve_adtaskhealth"> Managing health policies with scripting</a> Once health policies have been defined, the health monitoring controller determines how often health policies are verified to monitor for problems, when and how servers can be restarted, and in what time periods are server restarts prohibited.
