This is the central configuration file for the database. If the database
is running in a servlet-context, the configuration file will be read from
the WEB-INF directory of the web application. Otherwise, the configuration
is read from the directory specified by the exist.home system property.

Any unique attributes specified can also be overridden using a Java system
property, typically specified on the command line, of the form:
org.element.element....attribute
where the nesting of the element names follows the structure of the
XML configuration document, as was shown above.
For example, to override the value of the cache size to be 128MB you could
specify:
-Dorg.exist.db-connection.cacheSize=128M
on your JVM startup command line or options. Note that this only works
for unique, non-repeating elements, so you can't override things like
the transformer attribute element values or the XQuery module builtin
definitions, since they are not unique.
For detailed and latest information please consult the eXist documentation:

Configures the database backend.
- cacheSize:
the maximum amount of memory to use for database page buffers.
Each database file has an associated page buffer for B+-tree and
data pages. However, the memory specified via cacheSize is shared
between all page buffers. It represents an absolute maximum, which
would be occupied if all page buffers were completely full.
The cacheSize should typically not be more than half of the size of
the JVM heap size (set by the JVM -Xmx parameter). It can be larger
if you have a large-memory JVM (usually a 64bit JVM)
- checkMaxCacheSize:
specifies whether eXist should check the max cache size on startup
and reduce it if it is too large.
This value should normally be set to true.
Only set this value to false if:
a) You know what you are doing!
b) You have a JVM with tons of memory (typically using a 64-bit
JVM, which is the scenario this setting is intended for).
c) You are really sure you've complied with a) and b) above.
Setting this value to false may cause memory issues which may lead to
database corruptions, since it disables the automated max cache size
checks! You have been warned! ;-)
- collectionCache:
maximum amount of memory (in megabytes) to use for collection caches.
Memory calculation is just approximate. If your collections are very
different in size, it might be possible that the actual amount of
memory used exceeds the specified limit. You should thus be careful
with this setting.
- database:
selects a database backend. Currently, "native" is the only valid setting.
- files:
path to the directory where database files are stored.
- pageSize:
the size of one page on the disk. This is the smallest unit
transferred from and to the database files. Should be a multiple of
the operating system's file system page size (usually 4096).
- nodesBuffer:
size of the temporary buffer used by eXist for caching index
data while indexing a document. If set to -1, eXist will use the
entire free memory to buffer index entries and will flush the
cache once the memory is full.
If set to a value > 0, the buffer will be fixed to the given size.
The specified number corresponds to the number of nodes the
buffer can hold, in thousands. Usually, a good default could be
nodesBuffer="1000".
- cacheShrinkThreshold:
The minimum number of pages that must be read from a
cache between check intervals to be not considered for
shrinking. This is a measure for the "load" of the cache. Caches
with high load will never be shrinked. A negative value means that
shrinkage will not be performed.
- minDiskSpace:
The amount of disk space (in megabytes) which should be available for
the database to continue operations. If free disk space goes below
the configured limit, eXist-db will flush all buffers to disk and
switch to read-only mode in order to prevent potential data loss.
Set the limit large enough to allow all pending operations to
complete. Set to -1 to disable. The default is 1 gigabyte.
- posix-chown-restricted:
As defined by POSIX.1 for _POSIX_CHOWN_RESTRICTED.
When posix-chown-restricted="true" (the default) then:
1. Only a superuser process can change the user ID of the file.
2. A non-superuser process can change the group ID of the file
if the process owns the file (the effective user ID equals
the user ID of the file), and group equals either the
effective group ID of the process or one of the
process’s supplementary group IDs.
This means that when posix-chown-restricted="true", you can’t change
the user ID of your files. You can change the group ID of files that
you own, but only to groups that you belong to.
When posix-chown-restricted="false" you can change the user ID of
any file that you own, effectively "giving away the file" to
another user. Such a setting has negative security implications,
further details can be seen in the "Rationale" section for the
chown function in the POSIX.1-2017 (Issue 7, 2018 edition) standard.
See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/chown.html#tag_16_59_07
- preserve-on-copy
When copying Collections and Documents within the database, the
default (`false`), is not to preserve their attributes
(modification time, mode, user-id, group-id, and ACL).
NOTE: Not preserving attributes, is inline with both the GNU and
BSD `cp` commands, and therefore expected behaviour; The target
Collection or Document is created following the rules of the
target parent, and the effective user and their umask.
Setting preserve-on-copy="true" changes the default behaviour
so that the target Collection or Document of a copy, has the same
attributes as the source.
The preserve-on-copy setting can be overridden on a case-by-case
basis by setting the `preserve` flag to either `true` or `false`
when calling xmldb:copy(), or via any other API that supports copy.
Omitting the preserve flag when calling a copy operation, implies
the behaviour that is set in this configuration.
=====================================================================
The settings below are very conservative to avoid out-of-memory
exceptions on machines with limited memory (256MB).
Increase the buffer settings for elements_buffers and words_buffers if
you have some more memory to waste. If you deal with lots of
collections, you can also increase the collectionCacheSize value

- sync-period:
defines how often the database will flush its
internal buffers to disk. The sync thread will interrupt
normal database operation after the specified number of
milliseconds and write all dirty pages to disk.
- wait-before-shutdown:
defines how long the database instance will wait for running
operations to complete before it forces a shutdown. Forcing
a shutdown may leave the db in an unclean state and may
trigger a recovery run on restart.
Setting wait-before-shutdown="-1" means that the server will

Settings for the journaling and recovery of the database. With
recovery enabled, the database is able to recover from an unclean
database shutdown due to, for example, power failures, OS reboots,
and hanging processes. For this to work correctly, all database
operations must be logged to a journal file.
- enabled:
if this attribute is set to yes, automatic recovery is enabled.
- journal-dir:
this attribute sets the directory where journal files are to be
written. If no directory is specified, the default path is to
the data directory.
- size:
this attributes sets the maximum allowed size of the journal
file. Once the journal reaches this limit, a checkpoint will be
triggered and the journal will be cleaned. However, the database
waits for running transactions to return before processing this
checkpoint. In the event one of these transactions writes a lot
of data to the journal file, the file will grow until the
transaction has completed. Hence, the size limit is not enforced
in all cases.
- sync-on-commit:
this attribute determines whether or not to protect the journal
during operating system failures. That is, it determines whether
the database forces a file-sync on the journal after every
commit.
If this attribute is set to "yes", the journal is protected
against operating system failures. However, this will slow
performance - especially on Windows systems.
If set to "no", eXist will rely on the operating system to flush
out the journal contents to disk. In the worst case scenario,
in which there is a complete system failure, some committed
transactions might not have yet been written to the journal,
and so will be rolled back.
- group-commit:
If set to "yes", eXist will not sync the journal file
immediately after every transaction commit. Instead,
it will wait until the current file buffer (32kb)
is really full. This can speed up eXist on some systems
where a file sync is an expensive operation (mainly windows
XP; not necessary on Linux). However, group-comit="yes"
will increase the risk of an already committed
operation being rolled back after a database crash.
- force-restart:
Try to restart the db even if crash recovery failed. This is
dangerous because there might be corruptions inside the
data files. The transaction log will be cleared, all locks removed
and the db reindexed.
Set this option to "yes" if you need to make sure that the db is
online, even after a fatal crash. Errors encountered during recovery
are written to the log files. Scan the log files to see if any problems
occurred.
- consistency-check:
If set to "yes", a consistency check will be run on the database
if an error was detected during crash recovery. This option requires
force-restart to be set to "yes", otherwise it has no effect.
The consistency check outputs a report to the directory {files}/sanity
and if inconsistencies are found in the db, it writes an emergency
backup to the same directory.

This is the global configuration for the query watchdog. The
watchdog monitors all query processes, and can terminate any
long-running queries if they exceed one of the predefined limits.
These limits are as follows:
- output-size-limit:
this attribute limits the size of XML fragments constructed
using XQuery, and thus sets the maximum amount of main memory a
query is allowed to use. This limit is expressed as the maximum
number of nodes allowed for an in-memory DOM tree. The purpose
of this option is to avoid memory shortages on the server in
cases where users are allowed to run queries that produce very
large output fragments.
- query-timeout:
this attribute sets the maximum amount of time (expressed in
milliseconds) that the query can take before it is killed..
-->

Settings for the Database Lock Manager
- upgrade-check
Used by developers for diagnosing illegal lock upgrade issues. When enabled
checks for lock upgrading within the same thread, i.e. READ_LOCK -> WRITE_LOCK
are enabled. When an illegal upgrade is detected a LockException is thrown.
Such behaviour will likely corrupt any database writes, and should only be
used by developers when debugging database issues.
This can also be set via the Java System Properties `org.exist.lock-manager.upgrade-check`,
or (legacy) `exist.lockmanager.upgrade.check`.
- warn-wait-on-read-for-write
Used by developers for diagnosing lock performance issues. When enabled
checks for detecting when a thread wants to acquire the WRITE_LOCK
but another thread holds the READ_LOCK are enabled. When such operations
are detected a log message is written to locks.log at WARN level.
This can also be set via the Java System Properties `org.exist.lock-manager.warn-wait-on-read-for-write`,
or (legacy) `exist.lockmanager.warn.waitonreadforwrite`.
- paths-multi-writer
Set to true to enable Multi-Writer/Multi-Reader semantics for
the database Collection/Document Hierarchy as opposed to the default (false)
for Single-Writer/Multi-Reader.
NOTE: Whilst enabling Multiple-Writers on the Collection and Document Hierarchy can improve concurrent
through-put for write-heavy workloads, it can also can lead to deadlocks unless the User's
Collection Hierarchy is carefully designed to isolate query/database writes between Collection combs.
It is highly recommended that users leave this as the default setting. For more information, see:
"Locking and Cache Improvements for eXist-db", 2018-02-05, Section "Attempt 6" Page 58 -
https://www.evolvedbinary.com/technical-reports/exist-db/locking-and-cache-improvements/
This can also be set via the Java System Properties `org.exist.lock-manager.paths-multiple-writers`,

Settings for the Lock Table
- disabled
Disables the database lock table which tracks database locks. The Lock Table is enabled by default
and allows reporting on database locking via JMX.
NOTE: Tracking locks via the Lock Table imposes a small overhead per-Lock. Once users
have finished testing their system to ensure correct operation, they may wish to disable
this in production to ensure the absolute best performance.
This can also be set via the Java System Properties `org.exist.lock-manager.lock-table.disabled`,
or (legacy) `exist.locktable.disable`.
- trace-stack-depth
When set above 0, this captures n frames of each threads stack that performs a try/lock/release
operation. These frames are visible from JMX reporting.
In addition, when the logging level for the Lock Table is set in log4j2.xml to TRACE the lock
events are written to the locks.log file.
This can also be set via the Java System Properties `org.exist.lock-manager.lock-table.trace-stack-depth`,
or (legacy) `exist.locktable.trace.stack.depth`.
-->
<lock-table disabled="false" trace-stack-depth="0"/>
<!-- Settings for Document Locking
- use-path-locks
Set to true to have documents participate in the same hierarchical
path based locking strategy as Collections.
This has a performance and concurrency impact, but will ensure
that you cannot have deadlocks between Collections and Documents.
NOTE: in future this will likely be set to `true` by default.
This can also be set via the Java System Property `org.exist.lock-manager.document.use-path-locks`.

<!--
Settings for the Binary Manager:
- cache
Defines the class to use to Cache InputStreams when reading binary documents
from the database or from a read once source such as a http request (e.g. request:get-data()).
There are currently three options available:
- org.exist.util.io.FileFilterInputStreamCache
Default. Temporary binary streams are cached to a temporary file on disk.
- org.exist.util.io.MemoryMappedFileFilterInputStreamCache
Temporary binary streams are cached to a temporary file on disk which
has been mapped into memory. Faster than FileFilterInputStreamCache.
Not reliable on Windows platforms.
- org.exist.util.io.MemoryFilterInputStreamCache
Temporary binary streams are cached in memory.
This is the fastest approach. However it can result in out of memory
errors under heavy load or if using large binary files.
Where temporary files are used, they will be deleted after use.
However, due to a bug in the JVM on Windows platforms, temporary files cannot be deleted, so instead
they are re-cycled and re-used and deleted if the database is restarted.

Settings for the indexer:

- index-depth:
defines the maximum nesting depth of nodes which will be indexed
in the DOM index. Nodes below the specified nesting depth will
not be indexed in the DOM file. This has only an effect when
retrieving query results or for some types of XPath subexpressions,
like equality comparisons.
- suppress-whitespace:
should leading or trailing whitespace be removed from a text node?
Set to "leading", "trailing", "both" or "none".
Changing the parameter will only have an effect on newly loaded
files, not old ones.

-->
<scheduler>
<!--
Job definitions:
- type:
The type of the job to schedule. Must be either "system"
or "user".
system - System jobs require the database to be in a consistent state.
All database operations will be stopped until the method returns or
throws an exception. Any exception will be caught and a warning written to
the log.
user - User jobs may be scheduled at any time and may be mutually exclusive
or non-exclusive
- class:
If the job is written in Java then this should be the name of the
class that extends either -
org.exist.storage.SystemTask
org.exist.scheduler.UserJavaJob
- xquery:
If the job is written in XQuery (not suitable for system jobs) then
this should be a path to an XQuery stored in the database. e.g.
/db/myCollection/myJob.xql
XQuery job's will be launched under the guest account initially,
although the running XQuery may switch permissions through
calls to xmldb:login().
- cron-trigger:
To define a firing pattern for the Job using Cron style syntax
use this attribute otherwise for a periodic job use the period
attribute. Not applicable to startup jobs.
- unschedule-on-exception:
Boolean: yes/true, no/false. Default: true. If true and an exception is
encountered then the job is unscheduled for further execution until a
restart; otherwise, the exception is ignored.
- period:
Can be used to define an explicit period for firing the job instead
of a Cron style syntax. The period should be in milliseconds.
Not applicable to startup jobs.
- delay:
Can be used with a period to delay the start of a job. If unspecified jobs
will start as soon as the database and scheduler are initialised.
- repeat:
Can be used with a period to define for how many periods a job should be
executed. If unspecified jobs will repeat for every period indefinitely.

Default settings for the serializer. Most of these can be changed
by client code:
- add-exist-id:
for debugging: add an exist:id attribute to every element, showing
the internal node identifier (as a long int) assigned to this node.
Possible values are: "none", "element", "all". "all" displays the
node of every element node; "element" displays the id only for the
root nodes of the returned XML fragments.
- compress-output:
should the output be compressed when serializing documents?
Sometimes useful with remote clients.
Remember to add a statement like this to your client code:
service.setProperty("compress-output", "yes");
to uncompress the retrieved result in the client too.
- enable-xinclude:
should the database expand XInclude tags by default?
- enable-xsl:
should the database evaluate XSL processing instructions
when serializing documents?
- indent:
should the serializer pretty-print (indent) XML?
- match-tagging-attributes:
matches for attribute values can also be tagged using the character
sequence "||" to demarcate the matching text string. Since this
changes the content of the attribute value, the feature is disabled
by default.
- match-tagging-elements:
the database can highlight matches in the text content of a node by
tagging the matching text string with <exist:match>. Clearly, this
only works for XPath expressions using the some indexes.
Set the parameter to "yes" to enable this feature.

- "org.apache.xalan.processor.TransformerFactoryImpl"
- caching:
You can enable or disable xsl caching by this option.
This option is set to "yes" by default.
For further details see - http://atomic.exist-db.org/wiki/HowTo/XSLT2/
You can also include attribute child elements, if you wish to pass in
attributes to your particular TransformerFactory as follows:
<transformer class="net.sf.saxon.TransformerFactoryImpl">
<attribute name="http://saxon.sf.net/feature/version-warning"
value="false" type="boolean"/>
</transformer>
The example above sets Saxon to suppress warnings when executing a
XSLT 1.0 stylesheet with the XSLT 2.0 processor. Check the
documentation for your selected TransformerFactory to determine which
attributes can be set. Valid types include "boolean", "integer"
and "string". Anything else will be treated as type "string".
-->
<transformer class="net.sf.saxon.TransformerFactoryImpl" caching="yes">
<attribute name="http://saxon.sf.net/feature/version-warning" value="false" type="boolean"/>
</transformer>
<!--
Settings for XML validation
- mode
should XML source files be validated against a schema or DTD before
storing them? The setting is passed to the XML parser. The actual
effects depend on the parser you use. eXist comes with Xerces which
can validate against both: schemas and DTDs.
Possible values: "yes", "no", "auto". "auto" will leave validation
to the parser.
-->
<validation mode="no">
<!--
Specify the location of one or more catalog files. Catalogs are
used to resolve external entities in XML documents.
"${WEBAPP_HOME}" and "${EXIST_HOME}" can be used as magic string.
-->
<entity-resolver>
<catalog uri="${WEBAPP_HOME}/WEB-INF/catalog.xml"/>
</entity-resolver>
</validation>
<!--
Define modules that contain xQuery functions.
- enable-java-binding:
eXist supports calls to arbitrary Java methods from within
XQuery. Setting to "yes" might introduce a security risk.
- disable-deprecated-functions:
Set to "yes" to disable deprecated functions
- enable-query-rewriting:
Set to "yes" to enable the new query-rewriting optimizer. This
is work in progress and may lead to incorrect queries. Use at your
own risk.
- backwardCompatible:
Set to "yes" to enable backward compatibility (untyped argument
checks for instance)
- enforce-index-use
When set to "strict", eXist will not use a range index unless all
collections in the context sequence define it. When set to
"always", the query engine will still use an index, even if only
one collection has it defined. It thus leaves it to the user to
properly define indexes and if you forget to specify an index on
a particular collection, it will be missing in the results.
- raise-error-on-failed-retrieval
Set to "yes" if a call to doc(), xmldb:document(), collection() or
xmldb:xcollection() should raise an error (FODC0002) when an
XML resource can not be retrieved.
Set to "no" if a call to doc(), xmldb:document(), collection() or
xmldb:xcollection() should return an empty sequence when an
XML resource can not be retrieved.

Inserting new nodes into a document can lead to fragmentation
in the DOM storage file.
- allowed-fragmentation:
defines the maximum number of page splits allowed within a document
before a defragmentation run will be triggered.
- enable-consistency-checks:
for debugging only. If the parameter is set to "yes", a consistency
check will be run on every modified document after every XUpdate
request. It checks if the persistent DOM is complete and all
pointers in the structural index point to valid storage addresses
containing valid nodes.
