Domain: Control: Servers

Buttons     Column Display     

Use this page to change the state of the server instances configured in this WebLogic Server domain. Control operations on Managed Servers require starting the Node Manager. Starting Managed Servers in Standby mode requires the domain-wide administration port.

Buttons

Name Description
Start

Unlocks a server and enables it to receive new requests.

Servers can be locked with the java weblogic.Admin LOCK command. In a locked state, a server instance accepts only administrative logins.

MBean Attribute:
ServerRuntimeMBean.start

Resume

Resume suspended server. Allow new requests. This operation transitions the server into RUNNING state.

MBean Attribute:
ServerRuntimeMBean.resume

Suspend

Suspend server. Deny new requests (except by privileged users). Allow pending requests to complete. This operation transitions the server into ADMIN state. Applications and resources are fully available to administrators in ADMIN state. But non-admin users are denied access to applications and resources

Transitions the server from RUNNING to ADMIN state gracefully.

Applications are in admin mode. Inflight work is completed. Applications and resources are fully available to administrators in ADMIN state. But non-admin users are denied access to applications and resources

MBean Attribute:
ServerRuntimeMBean.suspend

Shutdown

Gracefully shuts down the server after handling inflight work.

Gracefully shuts down the server after handling inflight work; optionally ignores pending HTTP sessions while handling inflight work.

The following inflight work is allowed to complete before shutdown:

  • Pending transaction's and TLOG checkpoint

  • Pending HTTP sessions

  • Pending JMS work

  • Pending work in the execute queues

  • RMI requests with transaction context

Further administrative calls are accepted while the server is completing inflight work. For example a forceShutdown command can be issued to quickly shutdown the server if graceful shutdown takes a long time.

MBean Attribute:
ServerRuntimeMBean.shutdown

Restart SSL

Restart all SSL channels on which the server is listening. This could be necessary because of some change that the server is not aware of, for instance updates to the keystore.

MBean Attribute:
ServerRuntimeMBean.restartSSLChannels

Column Display

Name Description
Name

The alphanumeric name for this server instance.

MBean Attribute:
ServerMBean.Name

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

Type

The type of server (dynamic or explicitly configured).

Status

The status of the server.

Cluster

The cluster, or group of WebLogic Server instances, to which this server belongs.

If set, the server will listen for cluster multicast events.

MBean Attribute:
ServerMBean.Cluster

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

Machine

The WebLogic Server host computer (machine) on which this server is meant to run.

If you want to use Node Manager to start this server, you must assign the server to a machine and you must configure the machine for Node Manager.

You cannot change this value if a server instance is already running.

MBean Attribute:
ServerMBean.Machine

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

Virtual Machine Name

When WLS is running on JRVE, this specifies the name of the virtual machine running this server

MBean Attribute:
ServerMBean.VirtualMachineName

Current Machine
State

The current life cycle state of this server.

For example, a server can be in a RUNNING state in which it can receive and process requests or in an ADMIN state in which it can receive only administrative requests.

MBean Attribute:
ServerRuntimeMBean.State

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

Status of Last Action

Status information related to this task.

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.

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.

Notes:

To resolve a DNS name to an IP address, WebLogic Server must be able to contact an appropriate DNS server or obtain the IP address mapping locally. Therefore, if you specify a DNS name for the listen address, you must either leave a port open long enough for the WebLogic Server instance to connect to a DNS server and cache its mapping or you must specify the IP address mapping in a local file. If you specify an IP address for ListenAddress and then a client request specifies a DNS name, WebLogic Server will attempt to resolve the DNS name, but if it cannot access DNS name mapping, the request fails.

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.

Cluster Weight

The proportion of the load that this server will bear, relative to other servers in a cluster.

If all servers have the default weight or the same weight, each bears an equal proportion of the load. If one server has weight 50 and all other servers have weight 100, the 50-weight server will bear half as much load as any other server.

MBean Attribute:
ServerMBean.ClusterWeight

Minimum value: 1

Maximum value: 100

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

Expected To Run

If this server expected to run if the domain is started.

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

SSL Enabled
SSL Listen Port

The TCP/IP port at which this server listens for SSL connection requests.

MBean Attribute:
SSLMBean.ListenPort

Minimum value: 1

Maximum value: 65535

SSL Listen Port Enabled

Indicates whether the server can be reached through the default SSL listen port.

If the administration port is enabled for the WebLogic Server domain, then administrative traffic travels over the administration port and application traffic travels over the Listen Port and SSL Listen Port. If the administration port is disabled, then all traffic travels over the Listen Port and SSL Listen Port.

MBean Attribute:
SSLMBean.Enabled

Secure value: true

IIOP Enabled

Specifies whether this server has IIOP support enabled for both the regular (non-SSL) and SSL ports.

MBean Attribute:
ServerMBean.IIOPEnabled

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

Default IIOP Username

The user name of the default IIOP user. (Requires you to enable IIOP.)

MBean Attribute:
ServerMBean.DefaultIIOPUser

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

HTTPD Enabled

Whether or not HTTP support is enabled on the regular port or SSL port.

MBean Attribute:
ServerMBean.HttpdEnabled

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

Listen Thread Start Delay Secs

Returns the maximum time that the server will wait for server sockets to bind before starting a listen thread.

Properties to consider for removal

MBean Attribute:
ServerMBean.ListenThreadStartDelaySecs

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

Accept Backlog

The number of backlogged, new TCP connection requests that should be allowed for this server's regular and SSL ports.
