DbTxn.abort

APIRef

import com.sleepycat.db.*;

public void abort() throws DbException;

Description

The DbTxn.abort method causes an abnormal termination of the transaction.

The log is played backwards and any necessary recovery operations are initiated through the recover function specified to DbEnv.open. After the log processing is completed, all locks held by the transaction are released. As is the case for DbTxn.commit, applications that require strict two-phase locking should not explicitly release any locks.

In the case of nested transactions, aborting the parent transaction causes all children of that transaction to be aborted.

The DbTxn.abort method throws an exception that encapsulates a non-zero error value on failure.

Errors

If a fatal error occurs in Berkeley DB, the DbTxn.abort method will fail and throw a DbRunRecoveryException, at which point all subsequent database calls will fail in the same way.

In addition, the DbTxn.abort method may fail and throw an exception encapsulating a non-zero error for the following conditions:

EINVAL
The transaction was already aborted.

In addition, the DbTxn.abort method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
