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


Attributes

This section describes the following attributes:


AbandonTimeoutSeconds

Specifies the maximum amount of time, in seconds, a transaction manager persists in attempting to complete the second phase of a two-phase commit transaction.

During the second phase of a two-phase commit transaction, the transaction manager continues to try to complete the transaction until all resource managers indicate that the transaction is completed. 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 rolls 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 performs 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 synchronization occurs.

       
Privileges Read/Write
Typeint
Default Value10
Minimum value1
Maximum value2147483647

CachingDisabled

Private property that disables caching in proxies.

       
Privileges Read only
Typeboolean
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
Typeint
Default Value300
Minimum value10
Maximum value1800

CompletionTimeoutSeconds

Specifies the maximum amount of time, in seconds, a transaction manager waits for all resource managers to respond and indicate if the transaction can be committed or rolled back.

       
Privileges Read/Write
Typeint
Default Value0
Minimum value-1
Maximum value2147483647

ForgetHeuristics

Specifies whether the transaction manager automatically performs 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
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 time, in milliseconds, that a resource is declared dead. After the duration, the resource is 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 are maintained.

The first 1001 unique transaction names are maintained as their own transaction name and stored in each statistic. After the 1001st transaction name is reached, the transaction name is stored as weblogic.transaction.statistics.namedOverflow, and the transaction statistic is also merged and maintained in weblogic.transaction.statistics.namedOverflow.

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 time duration, in milliseconds, for 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

Notes

Optional information that you can include to describe this configuration.

WebLogic Server 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

ObjectName

Returns the ObjectName under which this MBean is registered in the MBean server.

Deprecated.

       
Privileges Read only

Typeboolean
Default Valuetrue

Parent

Return the immediate parent for this MBean

       
Privileges Read/Write
Type

Registered

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

Deprecated.

       
Privileges Read only
Typeboolean
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:



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

SerializeEnlistmentsGCIntervalMillis

Privileges Read/Write
Typelong
Default Value30000
Minimum value0

TimeoutSeconds

Specifies the maximum amount of time, in seconds, an active transaction is allowed to be in the first phase of a two-phase commit transaction. If the specified amount of time expires, the transaction is automatically rolled back.

       
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 amount of time, in seconds, a transaction manager waits for transactions involving the resource to complete before unregistering a resource. This grace period helps 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 blocks until the call returns 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 outstanding transactions are associated with the resource, the unregisterResource call returns and a log message is written to the server on which the resource was previously registered.

       
Privileges Read/Write
Typeint
Default Value30
Minimum value0
Maximum value2147483647

Default ValueSSLNotRequired
Legal Values
  • SSLNotRequired
  • SSLRequired
  • ClientCertRequired


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
