Overview

This bean represents a machine on which servers may be booted. A server is bound to a machine by calling to ServerMBean.setMachine(). Although it is typical that one MachineMBean refers to one physical machine and vice versa, it is possible to have a multihomed machine represented by multiple MachineMBeans. The only restriction is that each MachineMBean be configured with non-overlapping addresses. A configuration may contain one or more of MachineMBeans which may be looked up by their logical names.

      Operations

      This section describes the following operations:


      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

      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
