Examples of TransactionController

TransactionController is used to begin, commit and rollback local transactions @author Ludovic Orban
org.apache.derby.iapi.store.access.TransactionController
The TransactionController interface provides methods that an access client can use to control a transaction, which include the methods for gaining access to resources (conglomerates, scans, etc.) in the transaction controller's storage manager. TransactionControllers are obtained from an AccessFactory via the getTransaction method.
Each transaction controller is associated with a transaction context which provides error cleanup when standard exceptions are thrown anywhere in the system. The transaction context performs the following actions in response to cleanupOnError:
- If the error is an instance of StandardException that has a severity less than ExceptionSeverity.TRANSACTION_SEVERITY all resources remain unaffected.
- If the error is an instance of StandardException that has a severity equal to ExceptionSeverity.TRANSACTION_SEVERITY, then all resources are released. An attempt to use any resource obtained from this transaction controller after such an error will result in an error. The transaction controller itself remains valid, however.
- If the error is an instance of StandardException that has a severity greater than ExceptionSeverity.TRANSACTION_SEVERITY, then all resources are released and the context is popped from the stack. Attempting to use this controller or any resources obtained from it will result in an error.
Transactions are obtained from an AccessFactory. @see AccessFactory#getTransaction @see org.apache.derby.iapi.error.StandardException @see PersistentSet
org.apache.jmeter.control.TransactionController
Transaction Controller to measure transaction times There are two different modes for the controller: - generate additional total sample after nested samples (as in JMeter 2.2) - generate parent sampler containing the nested samples
