Designing a system configurationThe Java installation path setting made by the Builder (with Java Installation Path in theJVM monitor tab in Cluster Property) is shared by the servers in the cluster. The versionand update of Java VM used for JVM monitoring must be the same on every server in thecluster.The management port number setting made by the Builder (with Management Port in theConnection Setting dialog box opened from the JVM monitor tab in Cluster Property) isshared by all the servers in the cluster.Application monitoring is disabled when an application to be monitored on the IA32 versionis running on an x86_64 version OS or when an application to be monitored on an x86_64version is running on an IA32 version OS.If a large value such as 3,000 or more is specified as the maximum Java heap size by theBuilder (by using Maximum Java Heap Size on the JVM monitor tab in Cluster Property),The Java Resource Agent will fail to start up. The maximum heap size differs depending onthe environment, so be sure to specify a value based on the capacity of the mounted systemmemory.Using SingleServerSafe is recommended if you want to use the target Java VM loadcalculation function of the coordination load balancer.Mail reportingThe mail reporting function is not supported by STARTTLS and SSL.Requirements for network warning lightWhen using “DN-1000S” or “DN-1500GL,” do not set your password for the warning light.To play an audio file as a warning, you must register the audio file for “DN-1500GL”beforehand.
