public void commit() throws DbException;





Description



HThe DbTxn.commit method ends the transaction specified by the tid argument.

FIf DB_TXN_NOSYNC was not specified, a commit log record is written and;flushed to disk, as are all previously written log records.

BIf the transaction is nested, its locks are acquired by the parent.transaction, otherwise its locks are released.7Note: nested transactions are not yet supported.

GAny applications that require strict two-phase locking must not releaseFany locks explicitly, leaving them all to be released by DbTxn.commit.

The DbTxn.commitHmethod throws an exception that encapsulates an errno on failure.
