You can access this MBean from the following MBean attributes:

This section describes the following attributes:
Controls the flag that is used to initialize COM in native mode.
By default, when jCOM initializes COM in native mode, it starts
COM with the COINIT_MULTITHREADED
. This causes COM to
use Multi-Threaded Apartment (MTA) thread model. In the MTA model,
calls to an object are not synchronized by COM. Multiple clients
can concurrently call an object that supports this model on
different threads, and the object must provide synchronization in
its interface/method implementations using synchronization objects
such as events, mutexes, semaphores, etc. MTA objects can receive
concurrent calls from multiple out-of-process clients through a
pool of COM-created threads belonging to the object's process.
If the server logs a Class Not Registered Message when starting
COM in native mode, try setting this property. This will cause jCOM
to start COM in native mode, using
COINIT_APARTMENTTHREADED
option instead of the
COINIT_MULTITHREADED
option. In a component that is
marked as Apartment Threaded, each method of that component will
execute on a thread that is associated with that component. This
separates the methods into their own "Apartments", with each
instance of a component corresponding to one apartment. While there
is only one thread inside of a component, each instance of that
component will have its own thread apartment.
Privileges | Read/Write |
Type | boolean |
Specifies whether this server should log memory usage.
Privileges | Read/Write |
Type | boolean |
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 |
Type | java.lang.String |
Specifies whether this server should use native DLLs to allow Java objects to interact with COM objects. (Supported on Windows only.)
Privileges | Read/Write |
Type | boolean |
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
<
. Carriage returns/line feeds are
preserved.
If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.
Privileges | Read/Write |
Type | java.lang.String |
The address of the primary domain controller this server uses for authenticating clients. (If not specified, COM clients will not be authenticated.)
Privileges | Read/Write |
Type | java.lang.String |
Return the immediate parent for this MBean
Privileges | Read/Write |
Type |
Specifies whether this server should prefetch the next element in a java.lang.Enumeration (that had been improperly converted from a COM VariantEnumeration type) so the correct value is returned when the hasMoreElements() method is called.
Some COM methods return a COM VariantEnumeration type. The
java2com tool automatically converts the returned type into a
java.lang.Enumeration. This is not a perfect match since COM
enumerations have no equivalent to the
hasMoreElements()
call. The client must continue to
call nextElement
until a
NoSuchElementException
occurs. Setting this property
will cause jCOM to prefetch the next element in behind the scenes
and return the correct value when hasMoreElements is called.
Privileges | Read/Write |
Type | boolean |
Returns the type of the MBean.
Privileges | Read only |
Type | java.lang.String |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
Specifies whether verbose logging is enabled.

Type | boolean |
This section describes the following operations:
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.
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.
Operation Name | "freezeCurrentValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Returns true if the specified attribute has been set explicitly in this MBean instance.
Operation Name | "isSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
boolean
|
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.
Operation Name | "restoreDefaultValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Restore the given property to its default value.
Operation Name | "unSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
