Configuration Options

Name	Description
Timeout Seconds	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. MBean Attribute: JTAMBean.TimeoutSeconds Minimum value: 1 Maximum value: 2147483647
Abandon Timeout Seconds	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. MBean Attribute: JTAMBean.AbandonTimeoutSeconds Minimum value: 1 Maximum value: 2147483647
Before Completion Iteration Limit	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. MBean Attribute: JTAMBean.BeforeCompletionIterationLimit Minimum value: 1 Maximum value: 2147483647
Max Transactions	The maximum number of simultaneous in-progress transactions allowed on a server in this WebLogic Server domain. MBean Attribute: JTAMBean.MaxTransactions Minimum value: 1 Maximum value: 2147483647
Max Unique Name Statistics	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." MBean Attribute: JTAMBean.MaxUniqueNameStatistics Maximum value: 2147483647
Checkpoint Interval Seconds	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. MBean Attribute: JTAMBean.CheckpointIntervalSeconds Minimum value: 10 Maximum value: 1800
Forget Heuristics	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. MBean Attribute: JTAMBean.ForgetHeuristics
Unregister Resource Grace Period	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. MBean Attribute: JTAMBean.UnregisterResourceGracePeriod Maximum value: 2147483647
Execute XA Calls In Parallel	Indicates that XA calls are executed in parallel if there are available threads. MBean Attribute: JTAMBean.ParallelXAEnabled
Enable Two Phase Commit	Indicates that the two-phase commit protocol is used to coordinate transactions across two or more resource managers. If not selected: Two-phase commit is disabled and any attempt to use two-phase commit results in a RollbackException being thrown. All transaction logging is disabled, including checkpoint records. MBean Attribute: JTAMBean.TwoPhaseEnabled Changes take effect after you redeploy the module or restart the server.
Enable Tightly Coupled Transactions	Indicates tight coupling of transaction branches that span different transaction manager systems. When enabled, WebLogic uses the transaction identifier of a transaction imported by the InterposedTransactionManager for XA calls rather than an internally mapped Xid. This applies to inter-domain WebLogic transactions and transactions imported from Tuxedo. This allows for tight coupling of transaction branches for transactions that span across different transaction manager systems. If a transaction between WebLogic and Tuxedo resources uses a GridLink Data Source with GridLink Affinity enabled, the XA Affinity context is automatically used for the transaction. MBean Attribute: JTAClusterMBean.TightlyCoupledTransactionsEnabled
Enable Cluster-Wide Recovery	Indicates that cluster-wide recovery is used for distributed transactions. When enabled, recovery operations for a distributed transaction are applied to all the servers of the cluster hosting a InterposedTransactionManager rather than just the server hosting the InterposedTransactionManager. MBean Attribute: JTAClusterMBean.ClusterwideRecoveryEnabled
Write recovery logs when determiners configured	Indicates two-phase transaction recovery logs are written even if one or more determiners are configured. MBean Attribute: JTAMBean.TLOGWriteWhenDeterminerExistsEnabled
Determiners	Select a transaction resource (determiner) from the list of resources. For JMS, select WebLogic JMS as the determiner. When a determiner is configured, the determiner's in-doubt transaction records are used during transaction recovery. MBean Attribute: JTAMBean.Determiners

Advanced Configuration Options

Name	Description
Security Interoperability Mode	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. MBean Attribute: JTAMBean.SecurityInteropMode Changes take effect after you redeploy the module or restart the server.
Completion Timeout	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. The default value is 0, which sets the value to approximately twice the default transaction-timeout value with a maximum value of 120 seconds. This value provides backward compatibility for prior releases without this setting. If the specified value is -1, the maximum value supported by this attribute is used. If the specified value exceeds the value set for abandon-timeout-seconds, the value of abandon-timeout-seconds is used. MBean Attribute: JTAMBean.CompletionTimeoutSeconds Minimum value: -1 Maximum value: 2147483647
Maximum Duration of XA Calls	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. MBean Attribute: JTAMBean.MaxXACallMillis Maximum value: 9223372036854775807
Maximum Duration XA Resource Unavailable	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. MBean Attribute: JTAMBean.MaxResourceUnavailableMillis Maximum value: 9223372036854775807
Maximum Resource Requests on a Server	Maximum number of concurrent requests to resources allowed for each server. MBean Attribute: JTAMBean.MaxResourceRequestsOnServer Minimum value: 10 Maximum value: 2147483647
Web Service Transactions Transport Security Mode	Specifies transport security mode required by WebService Transaction endpoints. Transport Security options: SSLNotRequired All WebService Transaction protocol messages are exchanged over the HTTP channel. SSLRequired All WebService Transaction protocol messages are and can only be exchanged over the HTTPS. ClientCertRequired All WebService Transaction protocol messages are and can only be exchanged over the HTTPS, and WLS enforces the presence of client certificate MBean Attribute: JTAMBean.WSATTransportSecurityMode
Web Service Transactions Issued Token Enabled	Specifies whether to use issuedtoken to enable authentication between the WS-AT coordinator and participant. MBean Attribute: JTAMBean.WSATIssuedTokenEnabled
Recovery Site Name	The name of the site whose transactions this site/domain will recover in the event that intra-cluster transaction service migration is not successful or efficient. MBean Attribute: JTAMBean.RecoverySiteName
Cross Site Recovery Retry Interval	The interval at which a lease for a given server in a recovery domain will be checked for takeover eligibility. MBean Attribute: JTAMBean.CrossSiteRecoveryRetryInterval Minimum value: 1 Maximum value: 2147483647
Cross Site Recovery Lease Expiration	The time in seconds after which a lease expires making it eligible for recovery by another site. MBean Attribute: JTAMBean.CrossSiteRecoveryLeaseExpiration Minimum value: 1 Maximum value: 2147483647
Cross Site Recovery Lease Update	The time in seconds in which to update a lease timestamp. MBean Attribute: JTAMBean.CrossSiteRecoveryLeaseUpdate Minimum value: 1 Maximum value: 2147483647
