A server is an instance of WebLogic Server that runs in its own Java Virtual Machine (JVM) and has its own configuration.
This page summarizes each server that has been configured in the current WebLogic Server domain.
When you create a domain, you also create an Administration Server, which distributes configuration changes to other servers in the domain. In a typical production environment, you create one or more Managed Servers in the domain to host business applications and use the Administration Server only to configure and monitor the Managed Servers.
Name Description Create
Creates a new server instance.
Deletes the selected server instance.
Starts the selected server.
Resumes the selected server.
Suspends the selected server.
Shuts down the selected server.
Restarts SSL for the selected server.
Name Description Name
The alphanumeric name for this server instance.
The type of server (dynamic or explicitly configured).
The status of the server.
The cluster, or group of WebLogic Server instances, to which this server belongs.
If set, the server will listen for cluster multicast events.
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.
Virtual Machine Name
When WLS is running on JRVE, this specifies the name of the virtual machine running this server
Return the machine on which the server is running. This will be different from the configuration if the server gets migrated automatically.
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.
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.
Status of Last Action
Status information related to this task.
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.
The IP address or DNS name this server uses to listen for incoming connections. For example, enter
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:
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.
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.
Expected To Run
If this server expected to run if the domain is started.
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.
SSL Listen Port
The TCP/IP port at which this server listens for SSL connection requests.
SSL Listen Port Enabled
Indicates whether the default SSL listen port is enabled on the server
Specifies whether this server has IIOP support enabled for both the regular (non-SSL) and SSL ports.
Default IIOP Username
The user name of the default IIOP user. (Requires you to enable IIOP.)
Whether or not HTTP support is enabled on the regular port or SSL port.
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
The number of backlogged, new TCP connection requests that should be allowed for this server's regular and SSL ports.
Setting the backlog to
0may prevent this server from accepting any incoming connection on some operating systems.
Currently Open Sockets
The current number of sockets registered for socket muxing on this server.
Total Sockets Opened
The total number of registrations for socket muxing on this sever.
Heap Size Current
The current size (in bytes) of the JVM heap.
Heap Free Current
The current amount of memory (in bytes) that is available in the JVM heap.
The version of the operating system on which the JVM is running.
The current load that this server's Virtual Machine is placing on all processors in the host computer.
The version of this WebLogic Server instance (server).
User Lockout Total
Invalid Login Attempts Total
Login Attempts While Locked Total
Invalid Login Users High
Locked Users Current Count
Indicates whether JACC (Java Authorization Contract for Containers) was enabled on the commandline for the jvm hosting this server
