Clusters: Control Servers

Column Display     Related Tasks     Related Topics

This page lets you start, resume, suspend, or shutdown the servers assigned to this cluster. To perform these operations on a Managed Server, Node Manager must be running on the machine where the server is installed. Also, the server must have been started using Node Manager.

To start a Managed Server in the Standby startup mode, you must configure the domain-wide administration port.

Column Display

You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.

The following table lists all of the data points that you can display in columns on this page.

Name Description
Server

The server instances in this WebLogic domain.

Machine

The WebLogic Server host computer (machine) on which a server instance runs.

State

The current state of a server instance.

Status of Last Action

Status information related to this task.

Health

The health state of the server as reported by the server's self-health monitoring.

For example, the server can report if it is overloaded by too many requests, if it needs more memory resources, or if it will soon fail for other reasons.

MBean Attribute:
ServerRuntimeMBean.HealthState

Listen Port

The default TCP port that this server uses to listen for regular (non-SSL) incoming connections.

Administrators must have the right privileges before binding to a port or else this operation will not be successful and it will render the console un-reachable.

If this port is disabled, the SSL port must be enabled. Additional ports can be configured using network channels. The cluster (multicast) port is configured separately.

MBean Attribute:
ServerMBean.ListenPort

Minimum value: 1

Maximum value: 65535

Listen Address

The IP address or DNS name this server uses to listen for incoming connections. For example, enter 12.34.5.67 or mymachine, respectively.

Note that the value you specify for the listen address is not the URL to the host machine and it does not include the communication protocol, listen port, or channel.

Servers can be reached through the following URL:

protocol://listen-address:listen-port

Any network channel that you configure for this server can override this listen address.

If a server's listen address is undefined, clients can reach the server through an IP address of the computer that hosts the server, a DNS name that resolves to the host, or the localhost string. The localhost string can be used only for requests from clients that are running on the same computer as the server.

If you want to limit the valid addresses for a server instance, specify one of the following:

  • IP address. If you provide an IP address, clients can specify either the IP address or a DNS name that maps to the IP address. Clients that specify an IP address and attempt to connect through an SSL port must disable hostname verification.

  • DNS name. If you provide a DNS name, clients can specify either the DNS name or the corresponding IP address.

Do not leave the listen address undefined on a computer that uses multiple IP address (a multihomed computer). On such a computer, the server will bind to all available IP addresses.

Note also that if you are using the demo certificates in a multi-server domain, Managed Server instances will fail to boot if you specify the fully-qualified DNS name. For information about this limitation and suggested workarounds, see "Limitation on CertGen Usage" in Administering Security for Oracle WebLogic Server.

MBean Attribute:
ServerMBean.ListenAddress

Changes take effect after you redeploy the module or restart the server.

Heap Size Current

The current size (in bytes) of the JVM heap.

MBean Attribute:
JVMRuntimeMBean.HeapSizeCurrent

Heap Free Current

The current amount of memory (in bytes) that is available in the JVM heap.

MBean Attribute:
JVMRuntimeMBean.HeapFreeCurrent

Java Version

The Java version of the JVM.

MBean Attribute:
JVMRuntimeMBean.JavaVersion

OS Version

The version of the operating system on which the JVM is running.

MBean Attribute:
JVMRuntimeMBean.OSVersion

WebLogic Version

The version of this WebLogic Server instance (server).

MBean Attribute:
ServerRuntimeMBean.WeblogicVersion

Processor Load

The current load that this server's Virtual Machine is placing on all processors in the host computer.
