<li>The lock manager may now be fully partitioned, improving performance

on some multi-CPU systems. [#15880]</li>
|

|
|
<li>Replication groups are now architecture-neutral, supporting
|

connections between differing architectures (big-endian or
|
|||
|
|
little-endian, independent of structure padding). [#15787] [#15840]</li>
|

|
|
<li>Java: A new Direct Persistence Layer adds a built-in Plain Old Java Object (POJO)-based
|
|||
|
|
persistent object model, which provides support for complex object models without
|
|||
|
|
compromises in performance. For an introduction to the Direct Persistence Layer
|
|||
|
|
API, see Getting Started with Data Storage. [#15936]</li>
|

<li>Add the DB_ENV->set_intermediate_dir_mode method to support the
|
|||
|
|
creation of intermediate directories needed during recovery. [#15097]</li>
|
|||
|
|
<li>The DB_ENV->failchk method can now abort transactions for threads,
|
|||
|
|
which have failed while blocked on a concurrency lock. This
|
|||
|
|
significantly decreases the need for database environment recovery after
|
|||
|

thread of control failure. [#15626]</li>
|

|
|
<li>Replication Manager clients now can be configured to monitor the
|

|
|
connection to the master using heartbeat messages, in order to promptly
|
|||
|
|
discover connection failures. [#15714]</li>
|

they are created, improving performance on some systems. [#15758]</li>

<li>A new Direct Persistence Layer adds a built-in Plain Old Java Object (POJO)-based persistent object model, which provides support for complex object models without compromises in performance. For an introduction to the Direct Persistence Layer API, see Getting Started with Data Storage. [#15936]</li>
|

<li>Fixed a bug in the remove method of the Iterator instances returned by the StoredCollection.iterator method in the collections package. This bug caused ArrayIndexOutOfBoundsException in some cases when calling next, previous, hasNext or hasPrevious after calling remove. (Note that this issue does not apply to StoredIterator instances returned by the StoredCollection.storedIterator method.) This bug was reported in this forum thread: <a class="ulink" href="http://forums.oracle.com/forums/thread.jspa?messageID=2187896" target="_top">http://forums.oracle.com/forums/thread.jspa?messageID=2187896</a> [#15858]</li>

<li>Fixed a bug in the remove method of the StoredIterator instances returned by StoredCollection.storedIterator method in the collections package. If the sequence of methods next-remove-previous was called, previous would sometimes return the removed record. If the sequence of methods previous-remove-next was called, next would sometimes return the removed record. (Note that this issue does not apply to Iterator instances returned by the StoredCollection.iterator method.) [#15909]</li>
|
|||
|
|
<li>Fixed a bug that causes a memory leak for applications where many Environment objects are opened and closed and the CurrentTransaction or TransactionRunner class is used. The problem was reported in this JE Forum thread: <a class="ulink" href="http://forums.oracle.com/forums/thread.jspa?messageID=1782659" target="_top">http://forums.oracle.com/forums/thread.jspa?messageID=1782659</a> [#15444] </li>
|
|||
|

<li>Added StoredContainer.areKeyRangesAllowed method. Key ranges and the methods
|
|||
|
|
in SortedMap and SortedSet such as subMap and subSet are now explicitly disallowed
|
|||
|
|
for RECNO and QUEUE databases -- they are only supported for BTREE databases.

Before, using key ranges in a RECNO or QUEUE database did not work, but was not

explicitly prohibited in the Collections API. [#15936] </li>
