weblogic.management.configuration
Interface JTAMBean

All Superinterfaces:

ConfigurationMBean

public interface JTAMBean
extends ConfigurationMBean

This interface provides access to the JTA configuration attributes. The methods defined herein are applicable for JTA configuration at the domain level.

Deprecation of MBeanHome and Type-Safe Interfaces

This is a type-safe interface for a WebLogic Server MBean, which you can import into your client classes and access through weblogic.management.MBeanHome. As of 9.0, the MBeanHome interface and all type-safe interfaces for WebLogic Server MBeans are deprecated. Instead, client classes that interact with WebLogic Server MBeans should use standard JMX design patterns in which clients use the javax.management.MBeanServerConnection interface to discover MBeans, attributes, and attribute types at runtime. For more information, see "Developing Manageable Applications with JMX."

getTimeoutSeconds

int getTimeoutSeconds()

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.

Returns:

Transaction timeout in seconds.

Default Value:

30

setTimeoutSeconds

void setTimeoutSeconds(int timeout)
                       throws InvalidAttributeValueException,
                              DistributedManagementException

Sets the value of the TimeoutSeconds attribute.

Parameters:

timeout - Transaction timeout in seconds.

Throws:

InvalidAttributeValueException

DistributedManagementException

See Also:

JTAMBean.getTimeoutSeconds()

Maximum Value:

java.lang.Integer.MAX_VALUE

Minimum Value:

1

getAbandonTimeoutSeconds

int getAbandonTimeoutSeconds()

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.

Returns:

Abandon timeout in seconds. Default is 24 hours.

Default Value:

86400

setAbandonTimeoutSeconds

void setAbandonTimeoutSeconds(int timeout)
                              throws InvalidAttributeValueException,
                                     DistributedManagementException

Sets the value of the AbandonTimeoutSeconds attribute.

Parameters:

timeout - Abandon timeout in seconds.

Throws:

InvalidAttributeValueException

DistributedManagementException

Maximum Value:

java.lang.Integer.MAX_VALUE

Minimum Value:

1

getForgetHeuristics

boolean getForgetHeuristics()

Specifies 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.

Returns:

true if heuristic transactions are to be forgotten in affected resource managers, false otherwise.

Default Value:

true

setForgetHeuristics

void setForgetHeuristics(boolean forget)
                         throws InvalidAttributeValueException,
                                DistributedManagementException

Sets the value of the ForgetHeuristics attribute.

Parameters:

forget - Whether or not to forget heuristic transactions in affected resource managers.

Throws:

InvalidAttributeValueException

DistributedManagementException

See Also:

JTAMBean.getForgetHeuristics()

getBeforeCompletionIterationLimit

int getBeforeCompletionIterationLimit()

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.

Returns:

The maximum beforeCompletion iterations

Default Value:

10

setBeforeCompletionIterationLimit

void setBeforeCompletionIterationLimit(int iterations)
                                       throws InvalidAttributeValueException,
                                              DistributedManagementException

Sets the value of the BeforeCompletionIterationLimit attribute.

Parameters:

iterations - The maximum number of beforeCompletion iterations among registered objects.

getUnregisterResourceGracePeriod

int getUnregisterResourceGracePeriod()

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.

Returns:

The unregisterResource grace period in seconds.

Default Value:

30

setUnregisterResourceGracePeriod

void setUnregisterResourceGracePeriod(int seconds)
                                      throws InvalidAttributeValueException,
                                             DistributedManagementException

Sets the unregisterResource grace period.

Parameters:

seconds - The new grace period value.

Throws:

InvalidAttributeValueException

Maximum Value:

java.lang.Integer.MAX_VALUE

Minimum Value:

0

getSecurityInteropMode

String getSecurityInteropMode()

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.

Returns:

The security interoperability mode.

Default Value:

"default"

Valid Values:

"default", "performance", "compatibility"

setSecurityInteropMode

void setSecurityInteropMode(String mode)
                            throws InvalidAttributeValueException,
                                   DistributedManagementException

Sets the value of the SecurityInteropMode attribute.

Throws:

InvalidAttributeValueException

DistributedManagementException
