<p class="MsoNormal">Berkeley DB Java Edition 5.0.55 is a patch
release consisting of fixes for a number of issues. We strongly
recommend that users of the 5.0.x version upgrade to this
release. These fixes include:<o:p></o:p></p>
<ul type="disc">
<li class="MsoNormal" style="margin-bottom: 11pt;"> [#21537]
Fixed a critical bug that causes a database to be entirely
deleted after a crash (or abnormal shutdown, i.e., when not
calling Environment.close). The bug occurs when the database
is renamed just prior to the crash (or abnormal shutdown).
This bug was introduced in JE 5.0.48.</li>
<li class="MsoNormal" style="margin-bottom: 11pt;">[#21492]
Fixed an inefficiency in the Checkpointer which manifests
itself as
a large amount of time being spent in
<code>com.sleepycat.je.recovery.DirtyINMap.removeNextNode()</code>
calling
<code>java.util.HashMap$HashIterator.remove()</code> calling
<code>java.util.HashMap.removeEntryForKey()</code>. </li>
<li class="MsoNormal"
style="mso-margin-top-alt:auto;margin-bottom:11.0pt;mso-list:l0
level1 lfo3">[#21106]
An enhancement has been made to <code>DbVerify</code> to show
a histogram of
BIN counts by utilization percentage.This is a sample of the
output:
<pre>Verifying database p10
Checking tree for p10
BTree: Composition of btree, types and counts of nodes.
binCount=3,207
binEntriesHistogram=[40-49%: 3,093; 50-59%: 10; 60-69%: 22; 70-79%: 26;
80-89%: 21; 90-99%: 35]
binsByLevel=[level 1: count=3,207]
deletedLNCount=0

insByLevel=[level 2: count=48; level 3: count=1]
