List of startInternalTransaction() Examples

Examples of startInternalTransaction()

org.apache.derby.iapi.store.raw.RawStoreFactory.startInternalTransaction()

Create an internal transaction.

Starting an internal transaction always performs the following steps.

Create an raw store internal transaction context
Create a new idle internal transaction and then link it to the context.

AN internal transaction is identical to a user transaction with the exception that

Logical operations are not supported

Savepoints are not supported

Containers are not closed when commit() is called.

Pages are not unlatched (since containers are not closed) when commit() is called.

During recovery time internal transactions are rolled back before user transactions.

Raw Store Internal Transaction Context Behaviour
The cleanupOnError() method of this context behaves as follows:

If error is an instance of StandardException that has a severity less than ExceptionSeverity.TRANSACTION_SEVERITY then the internal transaction is aborted, the internal transaction is closed, the context is popped off the stack, and an exception of severity Transaction exception is re-thrown.

If error is an instance of StandardException that has a severity greater than or equal to ExceptionSeverity.TRANSACTION_SEVERITY then the context's internal transaction is aborted, the internal transaction is closed and the context is popped off the stack.

If error is not an instance of StandardException then the context's internal transaction is aborted, the internal transaction is closed and the context is popped off the stack.
