Class EnvironmentConfig</H2>
<PRE>
java.lang.Object
<IMG SRC="../../../resources/inherit.gif" ALT="extended by "><B>com.sleepycat.db.EnvironmentConfig</B>
</PRE>
<DL>
<DT><B>All Implemented Interfaces:</B> <DD>java.lang.Cloneable</DD>
</DL>
<HR>
<DL>
<DT><PRE>public class <B>EnvironmentConfig</B><DT>extends java.lang.Object<DT>implements java.lang.Cloneable</DL>
</PRE>
<P>
Specifies the attributes of an environment.
<p>
To change the default settings for a database environment, an application
creates a configuration object, customizes settings and uses it for
environment construction. The set methods of this class validate the
configuration values when the method is invoked. An
IllegalArgumentException is thrown if the value is not valid for that
attribute.
<p>
All commonly used environment attributes have convenience setter/getter
methods defined in this class. For example, to change the default
transaction timeout setting for an environment, the application should
do the following:
<p>
<blockquote><pre>
// customize an environment configuration
EnvironmentConfig envConfig = new EnvironmentConfig();
envConfig.setTxnTimeout(10000); // will throw if timeout value is invalid
// Open the environment.
Environment myEnvironment = new Environment(home, envConfig);
</pre></blockquote>
<p>
Additional parameters are described in the example.properties file found at
the top level of the distribution package. These additional parameters
will not be needed by most applications. This category of
properties can be specified for the EnvironmentConfig object through a
Properties object read by EnvironmentConfig(Properties), or
individually through EnvironmentConfig.setConfigParam().
<p>
For example, an application can change the default btree node size with:
<blockquote><pre>
envConfig.setConfigParam("je.nodeMaxEntries", "256");
</pre></blockquote>
<p>
Environment configuration follows this order of precedence:
<ol>
<li>Configuration parameters specified in <environment
home>/je.properties take first precedence.
<li>Configuration parameters set in the EnvironmentConfig object used
at Environment construction are next.
<li>Any configuration parameters not set by the application are set to
system defaults, described in the example.properties file.
</ol>
<p>
An EnvironmentConfig can be used to specify both mutable and immutable
environment properties. Immutable properties may be specified when the
first Environment handle (instance) is opened for a given physical
environment. When more handles are opened for the same environment, the
following rules apply:
<p>
<ol>
<li>Immutable properties must equal the original values specified when
constructing an Environment handle for an already open environment. When a
mismatch occurs, an exception is thrown.
<li>Mutable properties are ignored when constructing an Environment
handle for an already open environment.
</ol>
<p>
After an Environment has been constructed, its mutable properties may
be changed using
<A HREF="../../../com/sleepycat/db/Environment.html#setConfig(com.sleepycat.db.EnvironmentConfig)"><CODE>Environment.setConfig(com.sleepycat.db.EnvironmentConfig)</CODE></A>.

<PRE>
public void <B>setCacheSize</B>(long cacheSize)</PRE>
<DL>
<DD>Set the size of the shared memory buffer pool, that is, the size of the
cache.
<p>
The cache should be the size of the normal working data set of the
application, with some small amount of additional memory for unusual
situations. (Note: the working set is not the same as the number of
pages accessed simultaneously, and is usually much larger.)
<p>
The default cache size is 256KB, and may not be specified as less than
20KB. Any cache size less than 500MB is automatically increased by 25%
to account for buffer pool overhead; cache sizes larger than 500MB are
used as specified. The current maximum size of a single cache is 4GB.
(All sizes are in powers-of-two, that is, 256KB is 2^18 not 256,000.)
<p>
The database environment's cache size may also be set using the environment's
DB_CONFIG file. The syntax of the entry in that file is a single line
with the string "set_cachesize", one or more whitespace characters, and the cache size specified in three parts: the gigabytes of cache, the
additional bytes of cache, and the number of caches, also separated by
whitespace characters. For example, "set_cachesize 2 524288000 3" would
create a 2.5GB logical cache, split between three physical caches.
Because the DB_CONFIG file is read when the database environment is
opened, it will silently overrule configuration done before that time.
<p>
This method configures a database environment, including all threads
of control accessing the database environment, not only the operations
performed using a specified <A HREF="../../../com/sleepycat/db/Environment.html" title="class in com.sleepycat.db"><CODE>Environment</CODE></A> handle.
<p>
This method may not be called after the
environment has been opened.
If joining an existing database environment, any

<DD>Set the number of shared memory buffer pools, that is, the number of

<p>
It is possible to specify caches larger than 4GB and/or large enough
they cannot be allocated contiguously on some architectures. For
example, some releases of Solaris limit the amount of memory that may
be allocated contiguously by a process. This method allows applications
to break the cache broken up into a number of equally sized, separate
pieces of memory.
<p>
<p>
The database environment's cache size may also be set using the environment's
DB_CONFIG file. The syntax of the entry in that file is a single line
with the string "set_cachesize", one or more whitespace characters, and the cache size specified in three parts: the gigabytes of cache, the
additional bytes of cache, and the number of caches, also separated by
whitespace characters. For example, "set_cachesize 2 524288000 3" would

<p>
In some applications, the expense of page-faulting the underlying
shared memory regions can affect performance. For example, if the
page-fault occurs while holding a lock, other lock requests can
convoy, and overall throughput may decrease. This method
configures Berkeley DB to page-fault shared regions into memory when
initially creating or joining a database environment. In addition,
Berkeley DB will write the shared regions when creating an
environment, forcing the underlying virtual memory and filesystems
to instantiate both the necessary memory and the necessary disk
space. This can also avoid out-of-disk space failures later on.

Lock timeouts are checked whenever a thread of control blocks on a lock

As timeouts are only checked when the lock request first blocks or when
deadlock detection is performed, the accuracy of the timeout depends on
how often deadlock detection is performed.

When choosing log buffer and file sizes for in-memory logs, applications
should ensure the in-memory log buffer size is large enough that no
transaction will ever span the entire buffer, and avoid a state where the
in-memory buffer is full and no space can be freed because a transaction
that started in the first log "file" is still active.

Berkeley DB overwrites files using alternating 0xff, 0x00 and 0xff

journaling or logging filesystems will require operating system
support and probably modification of the Berkeley DB sources.

This flag should not be specified if more than a single process is

<DL>
<DD>Sets the clock skew ratio among replication group members based on the
fastest and slowest measurements among the group for use with master leases.
Calling this method is optional, the default values for clock skew assume no
skew. The user must also configure leases via the
<A HREF="../../../com/sleepycat/db/Environment.html#setReplicationConfig(com.sleepycat.db.ReplicationConfig, boolean)"><CODE>Environment.setReplicationConfig(com.sleepycat.db.ReplicationConfig, boolean)</CODE></A> method. Additionally, the user must
also set the master lease timeout via the
<A HREF="../../../com/sleepycat/db/Environment.html#setReplicationTimeout(com.sleepycat.db.ReplicationTimeoutType, int)"><CODE>Environment.setReplicationTimeout(com.sleepycat.db.ReplicationTimeoutType, int)</CODE></A> method and the number of sites in
the replication group via the (@link #setReplicationNumSites} method. These
methods may be called in any order. For a description of the clock skew
values, see <a href="../../../../ref/rep/clock_skew.html">Clock skew</a>.
For a description of master leases, see
<a href="../../../../ref/rep/lease.html">Master leases</a>.
<p>
These arguments can be used to express either raw measurements of a clock
timing experiment or a percentage across machines. For instance a group of
sites have a 2% variance, then <code>replicationClockskewFast</code> should be given as
102, and <code>replicationClockskewSlow</code> should be set at 100. Or, for a 0.03%
difference, you can use 10003 and 10000 respectively.
<p>
The database environment's replication subsystem may also be configured using
the environment's
<a href="../../../../ref/env/db_config.html#DB_CONFIG">DB_CONFIG</a> file.
The syntax of the entry in that file is a single line with the string
"rep_set_clockskew", one or more whitespace characters, and the clockskew
specified in two parts: the replicationClockskewFast and the replicationClockskewSlow. For example,
"rep_set_clockskew 102 100". Because the
<a href="../../../../ref/env/db_config.html#DB_CONFIG">DB_CONFIG</a> file is
read when the database environment is opened, it will silently overrule
configuration done before that time.

<DL>
<DD>Set a threshold for the minimum time that a client waits before requesting
retransmission of a missing message. Specifically, if the client detects a
gap in the sequence of incoming log records or database pages, Berkeley DB

retransmission of the missing record. Berkeley DB will double that amount
before requesting the same missing record again, and so on, up to a maximum
threshold, set by <A HREF="../../../com/sleepycat/db/EnvironmentConfig.html#setReplicationRequestMax(int)"><CODE>setReplicationRequestMax(int)</CODE></A>.
<p>
These values are thresholds only. Since Berkeley DB has no thread available

the Berkeley DB library to process an incoming replication message. Any
amount of time may have passed since the last message arrived and Berkeley DB
only checks whether the amount of time since a request was made is beyond the

By default the minimum is 40000 and the maximum is 1280000 (1.28 seconds).
These defaults are fairly arbitrary and the application likely needs to

<A NAME="setSegmentId(long)"><!-- --></A><H3>

<PRE>
public void <B>setSegmentId</B>(long segmentId)</PRE>
<DL>
<DD>Specify a base segment ID for database environment shared memory
regions created in system memory on VxWorks or systems supporting
X/Open-style shared memory interfaces; for example, UNIX systems
supporting <code>shmget</code> and related System V IPC interfaces.
<p>
This base segment ID will be used when database environment shared
memory regions are first created. It will be incremented a small
integer value each time a new shared memory region is created; that
is, if the base ID is 35, the first shared memory region created
will have a segment ID of 35, and the next one will have a segment
ID between 36 and 40 or so. A database environment always creates
a master shared memory region; an additional shared memory region
for each of the subsystems supported by the environment (Locking,
Logging, Memory Pool and Transaction); plus an additional shared
memory region for each additional memory pool cache that is
supported. Already existing regions with the same segment IDs will
be removed.
<p>
The intent behind this method is two-fold: without it, applications
have no way to ensure that two Berkeley DB applications don't
attempt to use the same segment IDs when creating different database
environments. In addition, by using the same segment IDs each time
the environment is created, previously created segments will be
removed, and the set of segments on the system will not grow without
bound.
The database environment's base segment ID may also be set using the environment's
DB_CONFIG file. The syntax of the entry in that file is a single line
with the string "set_shm_key", one or more whitespace characters, and the ID.
Because the DB_CONFIG file is read when the database environment is
opened, it will silently overrule configuration done before that time.
<p>
This method configures only operations performed using a single a
<A HREF="../../../com/sleepycat/db/Environment.html" title="class in com.sleepycat.db"><CODE>Environment</CODE></A> handle, not an entire database environment.

<p>
The files created to back in-memory access method databases will be
created relative to this path. These temporary files can be quite
large, depending on the size of the database.
<p>
If no directory is specified, the following alternatives are checked
in the specified order. The first existing directory path is used
for all temporary files.
<blockquote><ol>
<li>The value of the environment variable TMPDIR.
<li>The value of the environment variable TEMP.
<li>The value of the environment variable TMP.

<li>The directory /usr/tmp.
<li>The directory /temp.
<li>The directory /tmp.

<p>

<p>
Note: the GetTempPath interface is only checked on Win/32 platforms.

The database environment's temporary file directory may also be set using the environment's
DB_CONFIG file. The syntax of the entry in that file is a single line

<DL>
<DD>Configure the database environment to support at least txnMaxActive
active transactions.
<p>
This value bounds the size of the memory allocated for transactions.
Child transactions are counted as active until they either commit
or abort.
<p>
When all of the memory available in the database environment for
transactions is in use, calls to <A HREF="../../../com/sleepycat/db/Environment.html#beginTransaction(com.sleepycat.db.Transaction, com.sleepycat.db.TransactionConfig)"><CODE>Environment.beginTransaction</CODE></A>
will fail (until some active transactions complete). If this
interface is never called, the database environment is configured
to support at least 20 active transactions.
<p>
The database environment's number of active transactions may also be set using the environment's
DB_CONFIG file. The syntax of the entry in that file is a single line
with the string "set_tx_max", one or more whitespace characters, and the number of transactions.
Because the DB_CONFIG file is read when the database environment is
opened, it will silently overrule configuration done before that time.

<PRE>
public void <B>setTxnTimeout</B>(long txnTimeout)</PRE>
<DL>
<DD>Set the timeout value for the database environment
transactions.
<p>
Transaction timeouts are checked whenever a thread of control blocks on
a lock or when deadlock detection is performed. The lock is one
requested on behalf of a transaction, normally by the database access
methods underlying the application.
As timeouts are only checked when the lock request first blocks or when
deadlock detection is performed, the accuracy of the timeout depends on
how often deadlock detection is performed.
<p>

on a
per-transaction basis by <A HREF="../../../com/sleepycat/db/Transaction.html#setTxnTimeout(long)"><CODE>Transaction.setTxnTimeout</CODE></A>.

This means that transactions exhibit the ACI (atomicity, consistency,

integrity will be maintained, but if the system fails, it is possible
some number of the most recently committed transactions may be undone
during recovery. The number of transactions at risk is governed by how
often the system flushes dirty buffers to disk and how often the log is
checkpointed.
