Use this page to create health policies, which are used to perform a variety of health based assessments on clusters, dynamic clusters, and application server instances running on nodes. To view this administrative console page, click Operational Policies > Health Policies > New.
The excessive memory usage condition is a detection-based health policy that restarts as a method for cleaning up memory leaks. You can use this policy to perform health-based assessments on clusters, dynamic clusters, and application server instances running on nodes. In the case of dynamic clusters, regardless of the health policy you are using, the minimum number of dynamic cluster instances remains up and running.
Extended information about the health policy fields:
Percentage of maximum JVM heap size to monitor for | The excessive memory usage condition policy restarts members when the memory usage exceeds a percentage of your heap size over time. The total memory used percentage is used with the time-over-memory threshold value to determine when to restart members. Acceptable values for this field are whole numbers between 1 and 99. |
Time period over which the JVM heap threshold must breach | The excessive memory usage policy restarts members when the memory usage exceeds a percentage of your heap size over time. Acceptable values for this field are between 1 second and 60 minutes. |
