<div class="block">Statistics for a single environment. Statistics provide indicators for
|
||
|
|
system monitoring and performance tuning.
|
||
|
|
|
||
|
|
<p>Each statistic has a name and a getter method in this class. For example,
|
||
|
|
the <code>cacheTotalBytes</code> stat is returned by the <a href="../../../com/sleepycat/je/EnvironmentStats.html#getCacheTotalBytes--"><code>getCacheTotalBytes()</code></a> method. Statistics are categorized into several
|
||
|
|
groups, for example, <code>cacheTotalBytes</code> is in the <code>Cache</code>
|
||
|
|
group. Each stat and group has a name and a description.</p>
|
||
|
|
|
||
|
|
<p>Viewing the statistics through <a href="../../../com/sleepycat/je/EnvironmentStats.html#toString--"><code>toString()</code></a> shows the stat names
|
||
|
|
and values organized by group. Viewing the stats with <a href="../../../com/sleepycat/je/EnvironmentStats.html#toStringVerbose--"><code>toStringVerbose()</code></a> additionally shows the description of each stat and
|
||
|
|
group.</p>
|
||
|
|
|
||
|
|
<p>Statistics are periodically output in CSV format to the je.stat.csv file
|
||
|
|
(see <a href="../../../com/sleepycat/je/EnvironmentConfig.html#STATS_COLLECT"><code>EnvironmentConfig.STATS_COLLECT</code></a>). The column header in the .csv
|
||
|
|
file has <code>group:stat</code> format, where 'group' is the group name and
|
||
|
|
'stat' is the stat name. In Oracle NoSQL DB, in the addition to the .csv
|
||
|
|
file, JE stats are output in the .stat files.</p>
|
||
|
|
|
||
|
|
<p>Stat values may also be obtained via JMX using the <a
|
||
|
|
href="../../../../jconsole/JConsole-plugin.html">JEMonitor mbean</a>.
|
||
|
|
In Oracle NoSQL DB, JE stats are obtained via a different JMX interface in
|
||
|
|
JSON format. The JSON format uses property names of the form <code>group_stat</code> where 'group' is the group name and 'stat' is the stat name.</p>
|
||
|
|
|
||
|
|
<p>The stat groups are listed below. Each group name links to a summary of
|
||
|
|
the statistics in the group.</p>

<h3><a name="cache">Cache Statistics</a></h3>
|

|
|
<p style="margin-left: 2em">Group Name: "Cache"
|
||
|
|
<br/>Description: "The main cache resides in the Java heap and holds data, keys, Btree internal nodes, locks and JE metadata."</p>
|
||

<p style="margin-left: 2em">Group Name: "OffHeap"
|

|
|
<br/>Description: "The optional off-heap cache resides outside the Java heap and serves as an overflow area for the main cache."</p>
|
||
|
|
|
||
|
|
<p>The JE cache consists of the main (in-heap) cache and and optional
|
||
|
|
off-heap cache. The vast majority of the cache is occupied by Btree nodes,
|
||
|
|
including internal nodes (INs) and leaf nodes (LNs). INs contain record keys
|
||
|
|
while LNs contain record data.</p>
|
||
|
|
|
||
|
|
<p>Each IN refers to a configured maximum number of child nodes (<a href="../../../com/sleepycat/je/EnvironmentConfig.html#NODE_MAX_ENTRIES"><code>EnvironmentConfig.NODE_MAX_ENTRIES</code></a>). The INs form a Btree of at least 2
|
||
|
|
levels. With a large data set the Btree will normally have 4 or 5 levels.
|
||
|
|
The top level is a single node, the root IN. Levels are numbered from the
|
||
|
|
bottom up, starting with level 1 for bottom level INs (BINs). Levels are
|
||
|
|
added at the top when the root IN splits.</p>
|
||
|
|
|
||
|
|
<p>When an off-heap cache is configured, it serves as an overflow for the
|
||
|
|
main cache. See <a href="../../../com/sleepycat/je/EnvironmentConfig.html#MAX_OFF_HEAP_MEMORY"><code>EnvironmentConfig.MAX_OFF_HEAP_MEMORY</code></a>.</p>
|
||
|
|
|
||
|
|
<h4><a name="cacheSizing">Cache Statistics: Sizing</a></h4>
|
||
|
|
|
||
|
|
<p>Operation performance is often directly proportional to how much of the
|
||
|
|
active data set is cached. BINs and LNs form the vast majority of the cache.
|
||
|
|
Caching of BINs and LNs have different performance impacts, and behavior
|
||
|
|
varies depending on whether an off-heap cache is configured and which <a href="../../../com/sleepycat/je/CacheMode.html" title="enum in com.sleepycat.je"><code>CacheMode</code></a> is used.</p>
|
||
|
|
|
||
|
|
<p>Main cache current usage is indicated by the following stats. Note that
|
||
|
|
there is currently no stat for the number of LNs in the main cache.</p>

<p>A cache miss is considered a miss only when the object is not found in
|
||
|
|
either cache. Misses often result in file I/O and are a primary indicator
|
||
|
|
of cache performance. Fetches (access requests) and misses are indicated

<p>When the number of LN misses (<code>nLNsFetchMiss</code>) or the number of
|
||
|
|
BIN misses (<code>nBINsFetchMiss + nFullBINsMiss</code>) are significant, the
|
||
|
|
JE cache may be undersized, as discussed below. But note that it is not
|
||
|
|
practical to correlate the number of fetches and misses directly to
|
||
|
|
application operations, because LNs are sometimes
|
||
|
|
<a href="../../../com/sleepycat/je/EnvironmentConfig.html#TREE_MAX_EMBEDDED_LN"><code>embedded</code></a>, BINs are sometimes
|
||
|
|
accessed multiple times per operation, and internal Btree accesses are
|
||
|
|
included in the stat values.</p>
|
||
|
|
|
||
|
|
<p>Ideally, all BINs and LNs for the active data set should fit in cache so
|
||
|
|
that operations do not result in fetch misses, which often perform random
|
||
|
|
read I/O. When this is not practical, which is often the case for large
|
||
|
|
data sets, the next best thing is to ensure that all BINs fit in cache,
|
||
|
|
so that an operation will perform at most one random read I/O to fetch
|
||
|
|
the LN. The <a href="../../../com/sleepycat/je/util/DbCacheSize.html" title="class in com.sleepycat.je.util"><code>DbCacheSize</code></a> javadoc describes how to size the cache
|
||
|
|
to ensure that all BINs and/or LNs fit in cache.</p>
|
||
|
|
|
||
|
|
<p>Normally <a href="../../../com/sleepycat/je/EnvironmentConfig.html#MAX_MEMORY_PERCENT"><code>EnvironmentConfig.MAX_MEMORY_PERCENT</code></a> determines the JE
|
||
|
|
cache size as a value relative to the JVM heap size, i.e., the heap size
|
||
|
|
determines the cache size.</p>
|
||
|
|
|
||
|
|
<p>For configuring cache size and behavior, see:</p>

|
|
|

|
|
<p>When using Oracle NoSQL DB, a sizing exercise and <a href="../../../com/sleepycat/je/util/DbCacheSize.html" title="class in com.sleepycat.je.util"><code>DbCacheSize</code></a> are
|
||
|
|
used to determine the cache size needed to hold all BINs in memory. The
|
||
|
|
memory available to each node is divided between a 32 GB heap for the JVM
|
||
|
|
process (so that CompressedOops may be used) and the off-heap cache (when
|
||
|
|
more than 32 GB of memory is available).</p>
|
||
|
|
|
||
|
|
<p>It is also important not to configured the cache size too large, relative
|
||
|
|
to the JVM heap size. If there is not enough free space in the heap, Java
|
||
|
|
GC pauses may become a problem. Increasing the default value for <code>MAX_MEMORY_PERCENT</code>, or setting <code>MAX_MEMORY</code> (which overrides <code>MAX_MEMORY_PERCENT</code>), should be done carefully.</p>
|
||
|
|
|
||
|
|
<p>Java GC performance may also be improved by using <a href="../../../com/sleepycat/je/CacheMode.html#EVICT_LN"><code>CacheMode.EVICT_LN</code></a>. Record data sizes should also be kept below 1 MB to
|
||
|
|
avoid "humongous objects" (see Java GC documentation).</p>
|
||
|
|
|
||
|
|
<p>When using Oracle NoSQL DB, by default, <code>MAX_MEMORY_PERCENT</code> is
|
||
|
|
set to 70% and <a href="../../../com/sleepycat/je/CacheMode.html#EVICT_LN"><code>CacheMode.EVICT_LN</code></a> is used. The LOB (large object)
|
||
|
|
API is implemented using multiple JE records per LOB where the data size of
|
||
|
|
each record is 1 MB or less.</p>
|
||
|
|
|
||
|
|
<p>When a shared cache is configured, the main and off-heap cache may be
|
||
|
|
shared by multiple JE Environments in a single JVM process. See:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentConfig.html#SHARED_CACHE"><code>EnvironmentConfig.SHARED_CACHE</code></a></li>

|

|
</ul>
|
||
|
|
|
||
|
|
<p>When using Oracle NoSQL DB, the JE shared cache feature is not used
|
||
|
|
because each node only uses a single JE Environment.</p>

|

Ideally, key suffixes are small enough to be stored using the <a href="../../../com/sleepycat/je/EnvironmentConfig.html#TREE_COMPACT_MAX_KEY_LENGTH"><code>compact key format</code></a>. The

<h4><a name="cacheUnexpectedSizes">Cache Statistics: Unexpected
|

|
|
Sizes</a></h4>
|
||
|
|
|
||
|
|
<p>Although the Btree normally occupies the vast majority of the cache, it
|
||
|
|
is possible that record locks occupy unexpected amounts of cache when
|
||
|
|
large transactions are used, or when cursors or transactions are left open
|
||
|
|
due to application bugs. The following stat indicates the amount of cache
|
||
|
|
used by record locks:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentStats.html#getLockBytes--"><code>getLockBytes()</code></a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>To reduce the amount of memory used for record locks:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Use a small number of write operations per transaction. Write
|
||
|
|
locks are held until the end of a transaction.</li>
|
||
|
|
<li>For transactions using Serializable isolation or RepeatableRead
|
||
|
|
isolation (the default), use a small number of read operations per
|
||
|
|
transaction.</li>
|
||
|
|
<li>To read large numbers of records, use <a href="../../../com/sleepycat/je/LockMode.html#READ_COMMITTED"><code>LockMode.READ_COMMITTED</code></a> isolation or use a null Transaction (which
|
||
|
|
implies ReadCommitted). With ReadCommitted isolation, locks are
|
||
|
|
released after each read operation. Using <a href="../../../com/sleepycat/je/LockMode.html#READ_UNCOMMITTED"><code>LockMode.READ_UNCOMMITTED</code></a> will also avoid record locks, but does not
|
||
|
|
provide any transactional guarantees.</li>
|
||
|
|
<li>Ensure that all cursors and transactions are closed
|
||
|
|
promptly.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>Note that the above guidelines are also important for reducing contention
|
||
|
|
when records are accessed concurrently from multiple threads and
|
||
|
|
transactions. When using Oracle NoSQL DB, the application should avoid
|
||
|
|
performing a large number of write operations in a single request. For read
|
||
|
|
operations, NoSQL DB uses ReadCommitted isolation to avoid accumulation of
|
||
|
|
locks.</p>
|
||
|
|
|
||
|
|
<p>Another unexpected use of cache is possible when using a <a href="../../../com/sleepycat/je/DiskOrderedCursor.html" title="class in com.sleepycat.je"><code>DiskOrderedCursor</code></a> or when calling <a href="../../../com/sleepycat/je/Database.html#count--"><code>Database.count()</code></a>. The amount of

|
|
cache used by these operations is indicated by:</p>

<ul>

||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentStats.html#getDOSBytes--"><code>getDOSBytes()</code></a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><code>DiskOrderedCursor</code> and <code>Database.count</code> should normally be
|
||
|
|
explicitly constrained to use a maximum amount of cache memory. See:</p>
|
||
|
|
<ul>

<li><a href="../../../com/sleepycat/je/DiskOrderedCursorConfig.html#setInternalMemoryLimit-long-"><code>DiskOrderedCursorConfig.setInternalMemoryLimit(long)</code></a></li>

<h4><a name="cacheEviction">Cache Statistics: Eviction</a></h4>
|
||
|
|
|
||
|
|
<p>Eviction is removal of Btree node from the cache in order to make room
|
||
|
|
for newly added nodes. See <a href="../../../com/sleepycat/je/CacheMode.html" title="enum in com.sleepycat.je"><code>CacheMode</code></a> for a description of
|
||
|
|
eviction.</p>
|
||
|
|
|
||
|
|
<p>Normally eviction is performed via background threads in the eviction

thread pools. Disabling the eviction pool threads is not recommended.</p>

<p>Eviction stats are important indicator of cache efficiency and provide a

deeper understanding of cache behavior. Main cache eviction is indicated

|

by:</p>

|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>Note that objects evicted from the main cache are moved to the off-heap
|
||
|
|
cache whenever possible.</p>
|
||
|
|
|
||
|
|
<p>Off-heap cache eviction is indicated by:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentStats.html#getOffHeapLNsEvicted--"><code>getOffHeapLNsEvicted()</code></a></li>

<li><a href="../../../com/sleepycat/je/EnvironmentStats.html#getOffHeapDirtyNodesEvicted--"><code>getOffHeapDirtyNodesEvicted()</code></a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>When analyzing Java GC performance, the most relevant stats are <code>NLNsEvicted</code>, <code>NNodesMutated</code> and <code>NNodesEvicted</code>, which all
|
||
|
|
indicate eviction from the main cache based on LRU. Large values for these
|
||
|
|
stats indicate that many old generation Java objects are being GC'd, which
|
||
|
|
is often a cause of GC pauses.</p>
|
||
|
|
|
||
|
|
<p>Note that <a href="../../../com/sleepycat/je/CacheMode.html#EVICT_LN"><code>CacheMode.EVICT_LN</code></a> is used or when LNs are <a href="../../../com/sleepycat/je/EnvironmentConfig.html#TREE_MAX_EMBEDDED_LN"><code>embedded</code></a>, <code>NLNsEvicted</code> will
|
||
|
|
be close to zero because LNs are not evicted based on LRU. And if an
|
||
|
|
off-heap cache is configured, <code>NNodesMutated</code> will be close to zero
|
||
|
|
because BIN mutation takes place in the off-heap cache. If any of the three
|
||
|
|
values are large, this points to a potential GC performance problem. The GC
|
||
|
|
logs should be consulted to confirm this.</p>
|
||
|
|
|
||
|
|
<p>Large values for <code>NDirtyNodesEvicted</code> or <code>OffHeapDirtyNodesEvicted</code> indicate that the cache is severely undersized and
|
||
|
|
there is a risk of using all available disk space and severe performance
|
||
|
|
problems. Dirty nodes are evicted last (after evicting all non-dirty nodes)
|
||
|
|
because they must be written to disk. This causes excessive writing and JE
|
||
|
|
log cleaning may be unproductive.</p>
|
||
|
|
|
||
|
|
<p>Note that when an off-heap cache is configured, <code>NDirtyNodesEvicted</code> will be zero because dirty nodes in the main cache are
|
||
|
|
moved to the off-heap cache if they don't fit in the main cache, and are
|
||
|
|
evicted completely and written to disk only when they don't fit in the
|
||
|
|
off-heap cache.</p>
|
||
|
|
|
||
|
|
<p>Another type of eviction tuning for the main cache involves changing the
|
||
|
|
number of bytes evicted each time an evictor thread is awoken:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentConfig.html#EVICTOR_EVICT_BYTES"><code>EnvironmentConfig.EVICTOR_EVICT_BYTES</code></a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>If the number of bytes is too large, it may cause a noticeable spike in
|
||
|
|
eviction activity, reducing resources available to other threads. If the
|
||
|
|
number of bytes is too small, the overhead of waking the evictor threads
|
||
|
|
more often may be noticeable. The default values for this parameter is
|
||
|
|
generally a good compromise. This parameter also impacts critical eviction,
|
||
|
|
which is described next.</p>
|
||
|
|
|
||
|
|
<p>Note that the corresponding parameter for the off-heap cache, <a href="../../../com/sleepycat/je/EnvironmentConfig.html#OFFHEAP_EVICT_BYTES"><code>EnvironmentConfig.OFFHEAP_EVICT_BYTES</code></a>, works differently and is described
|
||
|

<p>Eviction is performed by eviction pool threads, calls to <a href="../../../com/sleepycat/je/Environment.html#evictMemory--"><code>Environment.evictMemory()</code></a> in application background threads, or via <a href="../../../com/sleepycat/je/CacheMode.html#EVICT_LN"><code>CacheMode.EVICT_LN</code></a> or <a href="../../../com/sleepycat/je/CacheMode.html#EVICT_BIN"><code>CacheMode.EVICT_BIN</code></a>. If these mechanisms are

|
|
not sufficient to evict memory from cache as quickly as CRUD operations are
|

|
|
adding memory to cache, then critical eviction comes into play. Critical
|

|
eviction is performed in-line in the thread performing the CRUD operation,

which is very undesirable since it increases operation latency.</p>

</ul>
|
||
|
|
|
||
|
|
<p>When using Oracle NoSQL DB, <code>EVICTOR_CRITICAL_PERCENTAGE</code> is set to
|
||
|
|
20% rather than using the JE default of 0%.</p>
|
||
|
|
|
||
|
|
<p>In the main cache, critical eviction uses the same parameter as
|
||
|
|
background eviction for determining how many bytes to evict at one
|
||
|
|
time:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentConfig.html#EVICTOR_EVICT_BYTES"><code>EnvironmentConfig.EVICTOR_EVICT_BYTES</code></a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>Be careful when increasing this value, since this will cause longer
|
||
|
|
operation latencies when critical eviction is occurring in the main
|
||
|
|
cache.</p>
|
||
|
|
|
||
|
|
<p>The corresponding parameter for the off-heap cache, <code>OFFHEAP_EVICT_BYTES</code>, works differently:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentConfig.html#OFFHEAP_EVICT_BYTES"><code>EnvironmentConfig.OFFHEAP_EVICT_BYTES</code></a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>Unlike in the main cache, <code>OFFHEAP_EVICT_BYTES</code> defines the goal
|
||
|
|
for background eviction to be below <code>MAX_OFF_HEAP_MEMORY</code>. The
|
||
|
|
background evictor threads for the off-heap cache attempt to maintain the
|
||
|
|
size of the off-heap cache at <code>MAX_OFF_HEAP_MEMORY -
|
||
|
|
OFFHEAP_EVICT_BYTES</code>. If the off-heap cache size grows larger than <code>MAX_OFF_HEAP_MEMORY</code>, critical off-heap eviction will occur. The default
|
||
|
|
value for <code>OFFHEAP_EVICT_BYTES</code> is fairly large to ensure that
|
||
|
|
critical eviction does not occur. Be careful when lowering this value.</p>
|
||
|
|
|
||
|
|
<p>This approach is intended to prevent the off-heap cache from exceeding
|
||
|
|
its maximum size. If the maximum is exceeded, there is a danger that the
|
||
|
|
JVM process will be killed by the OS. See <a href="../../../com/sleepycat/je/EnvironmentStats.html#getOffHeapAllocFailures--"><code>getOffHeapAllocFailures()</code></a>.</p>

<h4><a name="cacheLRUListContention">Cache Statistics: LRU List
|
||
|
|
Contention</a></h4>
|
||
|
|
|
||
|
|
<p>Another common tuning issue involves thread contention on the cache LRU
|
||
|
|
lists, although there is no stat to indicate such contention. Since each
|
||
|
|
time a node is accessed it must be moved to the end of the LRU list, a
|
||
|
|
single LRU list would cause contention among threads performing CRUD
|
||
|
|
operations. By default there are 4 LRU lists for each cache. If contention
|
||
|
|
is noticeable on internal Evictor.LRUList or OffHeapCache.LRUList methods,
|
||
|
|
consider increasing the number of LRU lists:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="../../../com/sleepycat/je/EnvironmentConfig.html#EVICTOR_N_LRU_LISTS"><code>EnvironmentConfig.EVICTOR_N_LRU_LISTS</code></a></li>

<li><a href="../../../com/sleepycat/je/EnvironmentConfig.html#OFFHEAP_N_LRU_LISTS"><code>EnvironmentConfig.OFFHEAP_N_LRU_LISTS</code></a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>However, note that increasing the number of LRU lists will decrease the
|
||
|
|
accuracy of the LRU.</p>

The log utilization is the percentage of the total log size (all .jdb

The obsolete portion of the log includes data that has expired at the

The <a href="../../../com/sleepycat/je/EnvironmentStats.html#getCurrentMinUtilization--"><code>minimum</code></a> and <a href="../../../com/sleepycat/je/EnvironmentStats.html#getCurrentMaxUtilization--"><code>maximum</code></a> utilization values are used to

drive cleaning.
|

|
<p>
|
||
|
|
The obsolete portion of the log includes data that has expired. An
|
||
|
|
expiration histogram is stored for each file and used to compute the
|
||
|
|
expired size. The minimum and maximum utilization are the lower and
|
||
|
|
upper bounds of computed utilization. They are different only when the
|
||
|
|
TTL feature is used, and some data in the file has expired while other
|
||
|
|
data has become obsolete for other reasons, such as record updates,
|
||
|
|
record deletions or checkpoints. In this case the strictly obsolete size
|
||
|
|
and the expired size may overlap because they are maintained separately.
|
||
|
|
<p>
|
||
|
|
If they overlap completely then the minimum utilization is correct,
|
||
|
|
while if there is no overlap then the maximum utilization is correct.
|
||
|
|
Both utilization values trigger cleaning, but when there is significant
|
||
|
|
overlap, the cleaner will perform two-pass cleaning.
|
||
|
|
<p>
|
||
|
|
In the first pass of two-pass cleaning, the file is read to recompute
|
||
|
|
obsolete and expired sizes, but the file is not cleaned. As a result of
|
||
|
|
recomputing the expired sizes, the strictly obsolete and expired sizes
|
||
|
|
will no longer overlap, and the minimum and maximum utilization will be
|
||
|
|
equal. If the file should still be cleaned, based on the recomputed
|
||
|
|
utilization, it is cleaned as usual, and in this case the number of
|
||
|
|
two-pass runs (this statistic) is incremented.
|
||
|
|
<p>
|
||
|
|
If the file should not be cleaned because its recomputed utilization is
|
||
|
|
higher than expected, the file will not be cleaned. Instead, its
|
||
|
|
recomputed expiration histogram, which has size information that now
|
||
|
|
does not overlap with the strictly obsolete data, is stored for future
|
||
|
|
use. By storing the revised histogram, the cleaner can select the most
|
||
|
|
appropriate files for cleaning in the future. In this case the number of
|
||
|
|
<a href="../../../com/sleepycat/je/EnvironmentStats.html#getNCleanerRevisalRuns--"><code>revisal runs</code></a> is incremented, and the
|
||

<p>Deletion of reserved files may be postponed for several reasons.
|
||
|
|
This occurs if an active file is protected (by a backup, for example),
|
||
|
|
and then the file is cleaned and becomes a reserved file. See
|
||
|
|
<a href="../../../com/sleepycat/je/EnvironmentStats.html#getProtectedLogSizeMap--"><code>getProtectedLogSizeMap()</code></a> for more information. In a
|
||
|
|
standalone JE environment, reserved files are normally deleted very
|
||
|
|
soon after being cleaned.</p>
|
||
|
|
|
||
|
|
<p>In an HA environment, reserved files are retained because they might
|
||
|
|
be used for replication to electable nodes that have been offline
|
||
|
|
for the <a href="../../../com/sleepycat/je/rep/ReplicationConfig.html#FEEDER_TIMEOUT"><code>ReplicationConfig.FEEDER_TIMEOUT</code></a>
|
||
|
|
interval or longer, or to offline secondary nodes. The replication
|
||
|
|
stream position of these nodes is unknown, so whether these files could
|
||
|
|
be used to avoid a network restore, when bringing these nodes online,
|
||
|
|
is also unknown. The files are retained just in case they can be used
|
||
|
|
for such replication. Files are reserved for replication on both master
|
||
|
|
and replicas, since a replica may become a master at a future time.
|
||
|
|
Such files will be deleted (oldest file first) to make room for a
|
||
|
|
write operation, if the write operation would have caused a disk limit
|
||
|
|
to be violated.</p>
|
||
|
|
|
||
|
|
<p>In NoSQL DB, this retention of reserved files has the additional
|
||
|
|
benefit of supplying the replication stream to subscribers of the
|
||
|
|
Stream API, when such subscribers need to replay the stream from an
|
||
|
|
earlier point in time.</p></div>

|
<p>This is the amount that can be logged by write operations, and
|
||
|
|
other JE activity such as checkpointing, without violating a disk
|
||
|
|
limit. The files making up <code>reservedLogSize</code> can be deleted to
|
||
|
|
make room for these write operations, so <code>availableLogSize</code> is
|
||
|
|
the sum of the current disk free space and the reserved size that is not
|
||
|
|
protected (<code>reservedLogSize</code> - <code>protectedLogSize</code>). The
|
||
|
|
current disk free space is calculated using the disk volume's free
|
||
|
|
space, <a href="../../../com/sleepycat/je/EnvironmentConfig.html#MAX_DISK"><code>EnvironmentConfig.MAX_DISK</code></a> and <a href="../../../com/sleepycat/je/EnvironmentConfig.html#FREE_DISK"><code>EnvironmentConfig.FREE_DISK</code></a>.</p>
|
||
|
|
|
||
|
|
<p>Note that when a record is written, the number of bytes includes JE
|
||
|
|
overheads for the record. Also, this causes Btree metadata to be
|
||
|
|
written during checkpoints, and other metadata is also written by JE.
|
||
|
|
So the space occupied on disk by a given set of records cannot be
|
||
|
|
calculated by simply summing the key/data sizes.</p>
|
||
|
|
|
||
|
|
<p>Also note that <code>availableLogSize</code> will be negative when a disk
|
||
|
|
limit has been violated, representing the amount that needs to be freed
|
||
|
|
before write operations are allowed.</p></div>

<p>When a BIN is considered for eviction based on LRU, if the BIN

Note that when an off-heap cache is configured, this stat value will be

zero because BIN mutation will take place only in the off-heap cache;

<p>When a BIN is stripped, all off-heap LNs that the BIN refers to are

evicted. The <a href="../../../com/sleepycat/je/EnvironmentStats.html#getOffHeapLNsEvicted--"><code>getOffHeapLNsEvicted()</code></a> stat is incremented

<p>A stripped BIN could be a BIN in main cache that is stripped of
|
||
|
|
off-heap LNs, or a BIN that is off-heap and also refers to off-heap
|
||
|
|
LNs. When a main cache BIN is stripped, it is removed from the
|
||
|
|
off-heap LRU. When an off-heap BIN is stripped, it is either modified
|
||
|
|
in place to remove the LN references (this is done when a small
|
||
|
|
number of LNs are referenced and the wasted space is small), or is
|
||
|
|
copied to a new, smaller off-heap block with no LN references.</p>
|
||
|
|
|
||
|
|
<p>After stripping an off-heap BIN, it is moved to the hot end of the
|
||
|
|
LRU list. Off-heap BINs are only mutated to BIN-deltas or evicted
|
||
|
|
completely when they do not refer to any off-heap LNs. This gives
|
||
|
|
BINs precedence over LNs in the cache.

avoids an LRU entry per off-heap LN, which would use excessive amounts

Note: Operations are currently counted as secondary DB (rather than

primary DB) operations only if the DB has been opened by the application

as a secondary DB. In particular the stats may be confusing on an HA

replica node if a secondary DB has not been opened by the application on
|

the replica.</div>
