Name Description Change
Changes the server template for this server.
Name Description Name
An alphanumeric name for this server instance.
This field will not accept spaces.
The name must be unique for all configuration objects in the domain. Within a domain, each server, machine, cluster, JDBC connection pool, virtual host, and any other resource type must be named uniquely and must not use the same name as the domain.
The server name is not used as part of the URL for applications that are deployed on the server. It is for your identification purposes only. The server name displays in the console, and if you use WebLogic Server command-line utilities or APIs, you use this name to identify the server.
In order to define a unicode server name, the underlying operating system must support unicode characters.
After you have created a server, you cannot change its name. Instead, clone the server and provide a new name for the clone.
The template used to configure this server.
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.
The cluster, or group of WebLogic Server instances, to which this server belongs.
If set, the server will listen for cluster multicast events.
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.
Listen Port Enabled
Specifies whether this server can be reached through the default plain-text (non-SSL) listen port.
If you disable this listen port, you must enable the default SSL listen port.
You can define additional listen ports for this server by configuring network channels.
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.
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.
SSL Listen Port
The TCP/IP port at which this server listens for SSL connection requests.
Client Cert Proxy Enabled
Specifies whether the
HttpClusterServletproxies the client certificate in a special header.
By default (or if you specify
weblogic.xmldeployment descriptor for each web application that is deployed on this server determines whether the web application trusts certificates sent from the proxy server plugin. By default (or if the deployment descriptor specifies
false), users cannot log in to the web application from a proxy server plugin.
A value of
truecauses proxy-server plugins to pass identity certifications from clients to all web applications that are deployed on this server instance. A proxy-server plugin encodes each identify certification in the
WL-Proxy-Client-Certheader and passes the header to WebLogic Server instances. A WebLogic Server instance takes the certificate information from the header, trusting that it came from a secure source, and uses that information to authenticate the user.
If you specify
true, use a
weblogic.security.net.ConnectionFilterto ensure that this WebLogic Server instance accepts connections only from the machine on which the proxy-server plugin is running. Specifying
truewithout using a connection filter creates a security vulnerability because the
WL-Proxy-Client-Certheader can be spoofed.
A cluster can also specify whether the
HttpClusterServletproxies the client certificate in a special header. The cluster-level setting overrides the setting in individual servers that are part of the cluster.
The Java compiler to use for all applications hosted on this server that need to compile Java code.
Specifies the volume of diagnostic data that is automatically produced by WebLogic Server at run time. Note that the WLDF diagnostic volume setting does not affect explicitly configured diagnostic modules. For example, this controls the volume of events generated for Flight Recorder.
This attribute has the following settings:
No diagnostic data is produced.
Minimal amounts of automatic diagnostic data are produced. This is the default.
Additional diagnostic data is automatically generated beyond the amount generated for
Additional diagnostic data is automatically generated beyond the amount generated for
The JNDI name of a system resource data source used to override the default datasource.

When WLS is running on JRVE, this specifies the name of the virtual machine running this server
WebLogic Plug-In Enabled
Specifies whether this server uses the proprietary
Set this attribute to
trueto specify that this server instance uses the proprietary
WL-Proxy-Client-IPheader, which is recommended if the server instance will receive requests from a proxy plug-in. If the server instance is a member of a cluster that will receive proxied requests, enable the WebLogic plug-in at the cluster level. For servers that are members of a cluster, the setting at the cluster level overrides the server's setting. When the WebLogic plug-in is enabled at the cluster level, a call to
getRemoteAddrwill return the address of the browser client from the proprietary
WL-Proxy-Client-IPheader instead of the Web server.
Set this attrbute to
falseto disable the
weblogic-plugin-enabled=false, in the
Note: If you are using Oracle HTTP Server, the WebLogic Proxy Plug-In, or Oracle Traffic Director to distribute client requests to a Managed Server or a cluster, Oracle recommends setting this attribute to

Extra RMI Compiler Options
The options passed to the RMIC compiler during server-side generation.
Each EJB component can override the compiler options that you specify here.
Extra EJB Compiler Options
The options passed to the EJB compiler during server-side generation.
Each EJB component can override the compiler options that you specify here. The following options are valid:
Forces generation of wrapper classes. Without this flag the classes may not be regenerated if it is determined to be unnecessary.
Generate ejb stub and skel as part of ejbc. Avoid HotCodeGen to have better performance.
Keep the generated .java files.
- -compiler javac
Java compiler to exec. If not specified, the -compilerclass option will be used.
- -compilerclass com.sun.tools.javac.Main
Specifies the compiler class to invoke.
Compile debugging info into class file.
Passed through to Symantec's sj.
- -classpath path
Classpath to use.
- -source source
Flags passed through to java runtime.
External Listen Address
The external IP address or DNS name for this server.
This address will be sent with HTTP session cookies and with dynamic server lists to HTTP proxies. It will also be used by external application clients to enable the propagation of RMI traffic through network address translating (NAT) firewalls.
You must specify an external DNS name for configurations in which a firewall is performing network address translation, unless clients are accessing WebLogic Server using t3 and the default channel. For example, define the external DNS name for configurations in which a firewall is performing network address translation, and clients are accessing WebLogic Server using HTTP via a proxy plug-in.
Local Administration Port Override
Overrides the domain-wide administration port and specifies a different listen port on which this server listens for administrative requests. Valid only if the administrative channel is enabled for the domain.
By default, if you enable the domain's administrative channel, all servers in the domain use the same listen port to listen for administrative requests.
The state in which this server should be started. If you specify
STANDBY, you must also enable the domain-wide administration port.
RUNNINGstate, a server offers its services to clients and can operate as a full member of a cluster. In the
ADMINstate, the server is up and running, but available only for administration operations, allowing you to perform server and application-level administration tasks without risk to running applications. In the
STANDBYstate, a server instance does not process any request; its regular Listen Port is closed. The Administration Port is open. It only accepts life cycle commands that transition the server instance to either the
SHUTDOWNstate. Other Administration requests are not accepted. A
STANDBYserver's only purpose is to resume into the
RUNNINGstate quickly; it saves server startup time.
JDBC LLR Table Name
The table name for this server's Logging Last Resource (LLR) database table(s). WebLogic Server creates the table(s) and then uses them during transaction processing for the LLR transaction optimization. This setting must be unique for each server. The default table name is
This setting only applies if this server hosts one or more LLR-enabled JDBC data sources.
The format for the tables that WebLogic Server creates is [[[catalog.]schema.]name.] Each "." in the table name is significant, and schema generally corresponds to username in many databases.
IMPORTANT: If this value is changed but the LLR table already exists in the database, you must preserve the existing table's data. Consequently, when changing the table name, the existing database table must be renamed by a database administrator to match the new configured table name. Otherwise, transaction records may be lost, resulting in heuristic failures that aren't logged.
IMPORTANT: Each server's table name must be unique. Multiple LLR-enabled data sources within the same server may share the same table, but multiple servers must not share the same table. If multiple same-named servers share a table, the behavior is undefined and it is likely that transactions will not recover properly after a crash, creating heuristic hazards.
RMI JDBC Security
The security protocol used by an RMI client to access a data source. Values are:
Secure: All incoming JDBC calls require administrator authentication. All other subjects, including anonymous, are rejected. Requires a configured SSL listen port.
Compatibility: Use an unsecure channel with the application's subject and no check for inbound administrator authentication when using RMI to access a data source. This setting reflects the legacy implementation behavior for RMI access to a data source and is a potential security vulnerability as it provides a client uncontrolled access to a database.
The default value is Compatibility.
