ImportErrorLogger

public class EventErrorLogger
extends Object

A simple logger for logging events that failed to be applied by DBSynchronizer. The output is two XML files, one a root file and another containing the actual XML elements. The root file name is the same as the one provided in the constructor. If not provided, it is failedevents.xml. The other file is with _entries appended to its name. The generated XML can then be provided to replay-failed-dmls GFXD command from the command line.

rollFileIfRequired

public String rollFileIfRequired(String logfile,
                        org.slf4j.Logger logger)
