Examples of com.sleepycat.je.utilint.Tracer

com.sleepycat.je.utilint.Tracer
The Tracer generates debug messages that are sent to the java.util.Logging facility. There are three log handlers set up for logging -- the database log itself, an output file, and stdout (the "console"). By default, only the database file is enabled.
