Factory Methods No factory methods. Instances of this MBean are created automatically.

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    
Type int
Default Value 86400
Minimum value 1
Maximum value 2147483647

 

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    
Type int
Default Value 10
Minimum value 1
Maximum value 2147483647

 

CachingDisabled

Private property that disables caching in proxies.

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

 

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    
Type int
Default Value 300
Minimum value 10
Maximum value 1800

 

ForgetHeuristics

Whether the transaction manager will automatically perform an XA Resource 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    
Type boolean
Default Value true

 

MaxResourceRequestsOnServer

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

   
Privileges Read/Write    
Type int
Default Value 50
Minimum value 10

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    
Type int
Default Value 1000
Minimum value 0
Maximum value 2147483647

 

MaxXACallMillis

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.

Type

 

Registered

Returns false if the the MBean represented by this object has been unregistered.

Deprecated.

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

 

SecurityInteropMode

Specifies the security mode of the communication channel used for XA calls between servers that participate in a global transaction. All server instances in a domain must have the same security mode setting.

Security Interoperability Mode options:

  • default

    The transaction coordinator makes calls using the kernel identity over an admin channel if it is enabled, and anonymous otherwise. Man-in-the-middle attacks are possible if the admin channel is not enabled.

  • performance

    The transaction coordinator makes calls using anonymous at all times. This implies a security risk since a malicious third party could then try to affect the outcome of transactions using a man-in-the-middle attack.

  • compatibility

    The transaction coordinator makes calls as the kernel identity over an insecure channel. This is a high security risk because a successful man-in-the-middle attack would allow the attacker to gain administrative control over both domains. This setting should only be used when strong network security is in place.



   
Privileges Read/Write    
Type java.lang.String
Default Value default
Legal Values

  • default

  • performance

  • compatibility

 

SerializeEnlistmentsGCIntervalMillis

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

   
Privileges Read/Write    
Type long
Default Value 30000
Minimum value 0

 

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    
Type int
Default Value 30
Minimum value 1
Maximum value 2147483647

 

Type

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.

 

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    
Type int
Default Value 30
Minimum value 0
Maximum value 2147483647

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"    
Parameters Object [] {  attributeName }

where:

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

    attributeName

Signature String [] { "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"    
Parameters Object [] {  propertyName }

where:

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

    property to check

Signature String [] { "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"    
Parameters Object [] {  attributeName }

where:

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

    attributeName

Signature String [] { "java.lang.String" }
Returns void
Exceptions

  • javax.management.AttributeNotFoundException

 

unSet

Restore the given property to its default value.

Operation Name "unSet"    
Parameters Object [] {  propertyName }

where:

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

    property to restore

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