MemoryException	This exception is thrown when a `DatabaseEntry` passed to a `Database` or `Cursor` method is not large enough to hold a value being returned.
MetaCheckSumFailException	A MetaCheckSumFailException is thrown when a checksum mismatch is detected on a database metadata page.
ReplicationDuplicateMasterException	The replication group has more than one master.

Package com.sleepycat.db Description

Berkeley DB Java API
[reference guide] [Java programming notes].

This package is a wrapper around the Berkeley DB library. It uses JNI to provide access to Berkeley DB, which is implemented in C. That means that a shared library or DLL must be available when applications use this package.

There are also several utilities provided with Berkeley DB that make administrative tasks possible from the command line. For more information, see the page Berkeley DB Supporting Utilities.
