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.
getTimeoutSeconds in interface JTAMBeanint getAbandonTimeoutSeconds()
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.
getAbandonTimeoutSeconds in interface JTAMBeanint getCompletionTimeoutSeconds()
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.
transaction-timeout value with a maximum value of 120 seconds. This
value provides backward compatibility for prior releases without this setting.abandon-timeout-seconds,
the value of abandon-timeout-seconds is used. getCompletionTimeoutSeconds in interface JTAMBeanboolean getForgetHeuristics()
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.
getForgetHeuristics in interface JTAMBeanint getBeforeCompletionIterationLimit()
The maximum number of cycles that the transaction manager
performs the beforeCompletion synchronization callback for
this cluster.
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.
getBeforeCompletionIterationLimit in interface JTAMBeanint getMaxTransactions()
The maximum number of simultaneous in-progress transactions allowed on a server in this cluster.
getMaxTransactions in interface JTAMBeanint getMaxUniqueNameStatistics()
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."
getMaxUniqueNameStatistics in interface JTAMBeanint getMaxResourceRequestsOnServer()
Maximum number of concurrent requests to resources allowed for each server.
getMaxResourceRequestsOnServer in interface JTAMBeanlong getMaxXACallMillis()
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.
getMaxXACallMillis in interface JTAMBeanlong getMaxResourceUnavailableMillis()
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.
getMaxResourceUnavailableMillis in interface JTAMBeanlong getRecoveryThresholdMillis()
The interval that recovery is attempted until the resource becomes available.
getRecoveryThresholdMillis in interface JTAMBeanint getMigrationCheckpointIntervalSeconds()
The time interval, in seconds, that the checkpoint is done for the migrated transaction logs (TLOGs).
getMigrationCheckpointIntervalSeconds in interface JTAMBeanlong getMaxTransactionsHealthIntervalMillis()
The interval for which the transaction map must be full for the JTA subsystem to declare its health as CRITICAL.
getMaxTransactionsHealthIntervalMillis in interface JTAMBeanint getPurgeResourceFromCheckpointIntervalSeconds()
The interval that a particular resource must be accessed within for it to be included in the checkpoint record.
getPurgeResourceFromCheckpointIntervalSeconds in interface JTAMBeanint getCheckpointIntervalSeconds()
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.
getCheckpointIntervalSeconds in interface JTAMBeanlong getSerializeEnlistmentsGCIntervalMillis()
The time interval, in milliseconds, at which internal objects used to serialize resource enlistment are cleaned up.
getSerializeEnlistmentsGCIntervalMillis in interface JTAMBeanboolean getParallelXAEnabled()
Indicates that XA calls are executed in parallel if there are available threads.
getParallelXAEnabled in interface JTAMBeanjava.lang.String getParallelXADispatchPolicy()
The dispatch policy to use when performing XA operations in parallel.
getParallelXADispatchPolicy in interface JTAMBeanint getUnregisterResourceGracePeriod()
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.
getUnregisterResourceGracePeriod in interface JTAMBeanjava.lang.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:
anonymous otherwise.
Man-in-the-middle attacks are possible if the admin channel is not enabled.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.getSecurityInteropMode in interface JTAMBeanboolean isTwoPhaseEnabled()
Indicates that the two-phase commit protocol is used to coordinate transactions across two or more resource managers.
If not selected:
isTwoPhaseEnabled in interface JTAMBeanboolean isClusterwideRecoveryEnabled()
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.
isClusterwideRecoveryEnabled in interface JTAMBeanboolean isTightlyCoupledTransactionsEnabled()
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.
isTightlyCoupledTransactionsEnabled in interface JTAMBeanjava.lang.String[] getDeterminers()
Specifies a list of one or more transaction resources (determiners) separated by line breaks. A determiner's in-doubt transaction records are used during transaction recovery when a TLog is not present.
getDeterminers in interface JTAMBeanboolean isTLOGWriteWhenDeterminerExistsEnabled()
Indicates two-phase transaction recovery logs are written even if one or more determiners are configured.
isTLOGWriteWhenDeterminerExistsEnabled in interface JTAMBeanint getShutdownGracePeriod()
Indicates how long the server should wait for active transactions to complete before allowing shutdown.
getShutdownGracePeriod in interface JTAMBeanint getMaxRetrySecondsBeforeDeterminerFail()
The maximum amount of time, in seconds, WebLogic Server waits for the determiner to recover from a failure. If the determiner does not recover after this period, WebLogic Server sets the TLog health state to HEALTH_FAILED.
getMaxRetrySecondsBeforeDeterminerFail in interface JTAMBean@Deprecated java.lang.String getRecoverySiteName()
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.

getCrossDomainRecoveryRetryInterval in interface JTAMBean@Deprecated int getCrossSiteRecoveryRetryInterval()
The interval at which a lease for a given server in a recovery domain will be checked for takeover eligibility.
getCrossSiteRecoveryRetryInterval in interface JTAMBean@Deprecated int getCrossSiteRecoveryLeaseExpiration()
The time after which a lease expires making it eligible for recovery by another site.
getCrossSiteRecoveryLeaseExpiration in interface JTAMBean@Deprecated int getCrossSiteRecoveryLeaseUpdate()
The time in seconds in which to update at lease timestamp.
getCrossSiteRecoveryLeaseUpdate in interface JTAMBean
