Access Points

You can access this MBean from the following MBean attributes:


    Attributes

    This section describes the following attributes:


    AbandonTimeoutSeconds

    The transaction abandon timeout seconds for transactions in the second phase of the two-phase commit (prepared and later).

    During the second phase of the two-phase commit process, the transaction manager will continue to try to complete the transaction until all resource managers indicate that the transaction is completed. Using this timeout, you can set the maximum time that a transaction manager will persist in attempting to complete a transaction during the second phase of the transaction. After the abandon transaction timer expires, no further attempt is made to resolve the transaction. If the transaction is in a prepared state before being abandoned, the transaction manager will roll back the transaction to release any locks held on behalf of the abandoned transaction.

           
    Privileges Read/Write
    Typeint
    Default Value86400
    Minimum value1
    Maximum value2147483647

    BeforeCompletionIterationLimit

    The maximum number of cycles that the transaction manager will perform the beforeCompletion synchronization callback for this WebLogic Server domain.

    Nothing prevents a Synchronization object from registering another during beforeCompletion, even those whose beforeCompletions have already been called. For example, an EJB can call another in its ejbStore() method. To accommodate this, the transaction manager calls all Synchronization objects, then repeats the cycle if new ones have been registered. This count sets a limit to the number of cycles that can happen.

           
    Privileges Read/Write
    Typeint
    Default Value10
    Minimum value1
    Maximum value2147483647

    CheckpointIntervalSeconds

    The interval at which the transaction manager creates a new transaction log file and checks all old transaction log files to see if they are ready to be deleted.

           
    Privileges Read/Write
    Typeint
    Default Value300
    Minimum value10
    Maximum value1800

    ForgetHeuristics

    Specifies whether the transaction manager will automatically perform an XAResource forget operation for heuristic transaction completions.

    When enabled, the transaction manager automatically performs an XA Resource forget() operation for all resources as soon as the transaction learns of a heuristic outcome. Disable this feature only if you know what to do with the resource when it reports a heuristic decision.

           
    Privileges Read/Write
    Typeboolean
    Default Valuetrue

    MaxResourceRequestsOnServer

    Maximum number of concurrent requests to resources allowed for each server.

           
    Privileges Read/Write
    Typeint
    Default Value50
    Minimum value10
    Maximum value2147483647

    MaxResourceUnavailableMillis

    Maximum duration in milliseconds that a resource is declared dead. After the duration, the resource will be declared available again, even if the resource provider does not explicitly re-register the resource.

           
    Privileges Read/Write
    Typelong
    Default Value1800000
    Minimum value0
    Maximum value9223372036854775807

    MaxTransactions

    The maximum number of simultaneous in-progress transactions allowed on a server in this WebLogic Server domain.

           
    Privileges Read/Write
    Typeint
    Default Value10000
    Minimum value1
    Maximum value2147483647

    MaxUniqueNameStatistics

    The maximum number of unique transaction names for which statistics will be maintained.

    A transaction name typically represents a category of business transactions (such as "funds-transfer")

           
    Privileges Read/Write
    Typeint
    Default Value1000
    Minimum value0
    Maximum value2147483647

    MaxXACallMillis

    Maximum allowed duration of XA calls to resources. If a particular XA call to a resource exceeds the limit, the resource is declared unavailable.

           
    Privileges Read/Write
    Typelong
    Default Value120000
    Minimum value0
    Maximum value9223372036854775807

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

    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.

           
    Privileges Read/Write
    Typejava.lang.String

    Parent

    Return the immediate parent for this MBean

           
    Privileges Read/Write
    Type
    Redeploy or Restart required Changes take effect after you redeploy the module or restart the server.

    SecurityInteropMode

    Specifies the security mode to use for XA calls in cross-domain transactions. Only applies to transactions in which some participating resources are running on older versions of WebLogic Server.

    In previous releases of WebLogic Server, the transaction coordinator used the kernel identity when calling to remote resources, however calls were made over a non-secure channel. In the current release, remote calls made as the kernel identity must use a secure channel, which causes an interoperability problem with previous WebLogic domains and a possible performance problem in JTA with an admin channel enabled. The security interoperability mode setting enables you to control the XA call behavior.

    Security Interoperability Mode options:



           
    Privileges Read/Write
    Typejava.lang.String
    Default Valuedefault
    Legal Values
    • default
    • performance
    • compatibility

    SerializeEnlistmentsGCIntervalMillis

    The interval at which internal objects used to serialize resource enlistment are cleaned up.

           
    Privileges Read/Write
    Typelong
    Default Value30000
    Minimum value0

    TimeoutSeconds

    The transaction timeout seconds for active transactions, before the prepared state.

    If the transaction is still in the "active" state after this time (counting from begin()), it is automatically rolled back. Once the transaction moves on to the prepared state, however, this timeout does not apply; the transaction is retried until all the resources are committed.

           
    Privileges Read/Write
    Typeint
    Default Value30
    Minimum value1
    Maximum value2147483647

    Type

    Returns the type of the MBean.

           
    Privileges Read only
    Typejava.lang.String
    Redeploy or Restart required Changes take effect after you redeploy the module or restart the server.

    UnregisterResourceGracePeriod

    The grace period (number of seconds) that the transaction manager waits for transactions involving the resource to complete before unregistering a resource. The grace period can help minimize the risk of abandoned transactions because of an unregistered resource, such as a JDBC data source module packaged with an application.

    During the specified grace period, the unregisterResource call will block until the call can return, and no new transactions are started for the associated resource. If the number of outstanding transactions for the resource goes to 0, the unregisterResource call returns immediately.

    At the end of the grace period, if there are still outstanding transactions associated with the resource, the unregisterResource call returns and a log message is written on the server on which the resource was previously registered.

           
    Privileges Read/Write
    Typeint
    Default Value30
    Minimum value0
    Maximum value2147483647


    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

    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

    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
