This page is linked from the [[Getting Started]] Section.
The options listed on this page influence the way how database [[Commands|commands]] are executed and XQuery expressions are evaluated. Options are divided into [[#Global Options|global options]], which are valid for all BaseX instances, and local options, which are specific to a client or session. Values Two kinds of options are either ''strings'', ''numbers'' or ''booleans''.exist:
The {{Code|.basex}} * '''[[Configuration#Configuration FilesGlobal Options|configuration fileGlobal Options]] is parsed by every new local ''' are valid for all BaseX instanceinstances in the same JVM. It This is used to store particularly relevant if you are working with the client/server architecture.* '''Local options ''' (all remaining ones) are specific to disk:a client or session.
* Global Values of options can only be set via the configuration file are either ''strings'', ''numbers'' or system properties ''booleans''. Options are ''static'' and not bound to a single operation (see belowfor example, the next command).* Local Various ways exist to access and change options can also be specified in the configuration file after the {{Code|# Local Options}} comment.:
Various ways exist to access * The current value of an option can be requested with the {{Command|GET}} command. Local options can be changed via {{Command|SET}} (all global options, except for {{Option|DEBUG}}, can only be changed at startup time). If an option is of type ''boolean'', and change options:if no value is specified, its current value will be inverted.
* The current value of an option can be requested with the [[Commands#GET{{Code|GET]] and changed with the .basex}} [[CommandsConfiguration#SETConfiguration Files|SETconfiguration file]] commandis parsed by every new local BaseX instance. All values are ''static'': they stay valid until they are changed once again by another operationIt contains all global options. If an option is Local options can be specified at the end of type ''boolean'', and if no value is specified, its existing value will be inverted.the file after the {{Code|Local Options}} comment:
<syntaxhighlight lang="perl"># General OptionsDEBUG = false... # Local OptionsCHOP = false</syntaxhighlight> * Initial values for global options can also be specified via system properties, which can e.g. be passed on with the [httphttps://docs.oracle.com/javaseen/1.4.2java/docsjavase/tooldocs11/windowstools/java.html#options -D flag] on command line, or using [httphttps://docs.oracle.com/en/java/javase/611/docs/api/java.base/java/lang/System.html#setProperty(java.lang.String,%20javajava.lang.String) System.setProperty()] before creating a BaseX instance. The specified keys needs need to be prefixed with {{Code|org.basex.}}. An example:
<pre classsyntaxhighlight lang="brush:bashperl">
java -Dorg.basex.CHOP=false -cp basex.jar org.basex.BaseX -c"get chop"
CHOP: false
</presyntaxhighlight>
* Options If using the Mac OS X packaged application then global options can also be set in within the prolog of an XQuery expressionInfo. In plist file within the option declaration, options need to be bound to Contents folder of the [[Database Module]] namespaceapplication package. All values will be reset after the evaluation of a queryFor example:
<pre classsyntaxhighlight lang="brush:xqueryxml">declare option db:chop 'false';<key>JVMOptions</key><array> <string>-Dorg.basex..CHOP=false</string></array></presyntaxhighlight* In a [[Web Application]], the default can be adjusted in the {{Code|web.xml}} file as follows:
* Options can also be applied locally by using pragmas:<syntaxhighlight lang="xml"><context-param> <param-name>org.basex.chop</param-name> <param-value>false</param-value></context-param></syntaxhighlight>
<pre class="brush:xquery">(* In XQuery, local options can be set via option declarations and [[XQuery Extensions# db:chop false #) { parse-xml('<xml> hi </xml>') }</pre>Pragmas|pragmas]].
If options are implicitly changed by operations in the [[GUI]], the underlying commands will be listed in the [[GUI#Visualizations|Info View]].<br/><br/>

Read transactions will be favored, and transactions that access no databases can be evaluated even if local the limit of parallel transactions (databasespecified via {{Option|PARALLEL}}) or global (process) locking will has been reached. This prevents update operations from blocking all other requests. For example, the DBA can further be used for managing to see which jobs are running, even if the queue is full.* If fair locking is enabled, read and write transactions will be treated equally (first in, first out). This avoids starvation of update operations, and it should be used if the prompt evaluation of update operations is critical.

It can be changed after thatfor existing databases by running {{Command|OPTIMIZE}} with the {{Code|ALL}} keyword or [[Database_Module#db:optimize|db:optimize($db, true())]].* The advantage of incremental indexes is that After each update, the value index structures indexes will always be uprefreshed as well. Incremental updates are currently not available for the full-to-datetext index and database statistics.* The downside is that updates will take longer.
