This section describes attributes that provide access to other MBeans.


    EnabledServers

    The list of target servers for trap generation. If no server is specified, no trap will be generated.

    Relationship type: Reference.


    Attributes

    This section describes the following attributes:


    AttributeMBeanName

    The name of the MBean instance that you want to monitor. If you leave the name undefined, WebLogic Server monitors all instances of the MBean type that you specify in Monitored MBean Type.

    Do not enter the full JMX object name of the MBean instance. Instead, enter only the value that you provided when you created the instance. To create unique MBean object names, WebLogic Server encodes several name-value pairs into each object name. One of these pairs is Name=name, and this is the value that you enter for MBean Name. For example:
    "MedRec:Name=MedRecServer,
    Type=ServerRuntime"

    In the previous example, specify MedRecServer as the name of the MBean instance.

           
    Privileges Read/Write
    Typejava.lang.String

    AttributeMBeanType

    The MBean type that defines the attribute you want to monitor. Do not include the MBean suffix. For example, specify Server to monitor a ServerMBean.

    WebLogic Server does not support using Attribute Change notifications to monitor run-time attributes. Runtime MBeans always include the word Runtime in their names. For example, the ServerRuntime MBean provides access to runtime attributes while the Server MBean provides access to configuration attributes. To monitor changes in an MBean that includes Runtime in its name, use a String Monitor, Gauge Monitor, or Counter Monitor.

           
    Privileges Read/Write
    Typejava.lang.String

    AttributeName

    The name of the attribute that you want to monitor. This attribute must be in the WebLogic Server MIB.

           
    Privileges Read/Write
    Typejava.lang.String

    CachingDisabled

    Private property that disables caching in proxies.

           
    Privileges Read only

    Typejavax.management.MBeanInfo
    Redeploy or Restart required Changes take effect after you redeploy the module or restart the server.

    Name

    The user-specified name of this MBean instance.

    This name is included as one of the key properties in the MBean's javax.management.ObjectName:
    Name=user-specified-name

           
    Privileges Read/Write
    Typejava.lang.String

    Notes

    Optional information that you can include to describe this configuration.

    WebLogic Sever saves this note in the domain's configuration file (config.xml) as XML PCDATA. All left angle brackets (<) are converted to the XML entity &lt;. Carriage returns/line feeds are preserved.

    Note:

    If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.

    Operations

    This section describes the following operations:


    addEnabledServer

    Adds a feature to the EnabledServer attribute of the SNMPTrapSourceMBean object

       
    Operation Name"addEnabledServer"
    ParametersObject [] {  server }

    where:

    • server is an object of type weblogic.management.configuration.ServerMBean that specifies:

      The feature to be added to the EnabledServer attribute

    SignatureString [] { "weblogic.management.configuration.ServerMBean" }
    Returns boolean
    Exceptions
    • javax.management.InvalidAttributeValueException
    • weblogic.management.configuration.ConfigurationException

    freezeCurrentValue

    If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.

    Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.

    Note:

    To insure that you are freezing the default value, invoke the restoreDefaultValue operation before you invoke this.

    This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.

    Deprecated. 9.0.0.0

       
    Operation Name"freezeCurrentValue"
    ParametersObject [] {  attributeName }

    where:

    • attributeName is an object of type java.lang.String that specifies:

      attributeName

    SignatureString [] { "java.lang.String" }
    Returns void
    Exceptions
    • javax.management.AttributeNotFoundException
    • javax.management.MBeanException

    isSet

    Returns true if the specified attribute has been set explicitly in this MBean instance.

       
    Operation Name"isSet"
    ParametersObject [] {  propertyName }

    where:

    • propertyName is an object of type java.lang.String that specifies:

      property to check

    SignatureString [] { "java.lang.String" }
    Returns boolean

    removeEnabledServer

       
    Operation Name"removeEnabledServer"
    ParametersObject [] {  server }

    where:

    • server is an object of type weblogic.management.configuration.ServerMBean that specifies:

      server

    SignatureString [] { "weblogic.management.configuration.ServerMBean" }
    Returns boolean
    Exceptions
    • javax.management.InvalidAttributeValueException
    • weblogic.management.configuration.ConfigurationException

    restoreDefaultValue

    If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.

    Default values are subject to change if you update to a newer release of WebLogic Server. To prevent the value from changing if you update to a newer release, invoke the freezeCurrentValue operation.

    This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.

    Deprecated. 9.0.0.0

       
    Operation Name"restoreDefaultValue"
    ParametersObject [] {  attributeName }

    where:

    • attributeName is an object of type java.lang.String that specifies:

      attributeName

    SignatureString [] { "java.lang.String" }
    Returns void
    Exceptions
    • javax.management.AttributeNotFoundException

    unSet

    Restore the given property to its default value.

       
    Operation Name"unSet"
    ParametersObject [] {  propertyName }

    where:

    • propertyName is an object of type java.lang.String that specifies:

      property to restore

    SignatureString [] { "java.lang.String" }
    Returns void
