All Implemented Interfaces:

JournalConstants

public class RenamingJournalRecoveryLog
extends JournalRecoveryLog

A production-oriented implementation of JournalRecoveryLog.

The name of the log file contains a time-stamp, so we can be sure that it won't over-write an existing log file. Also, the name is prefixed with an '_' (underscore) while the recovery is in progress, so we can see when it finishes.
