Confluence has a small number of obscure configuration and debugging settings that can be enabled through Java system properties. System properties are usually set by passing the -D flag to the Java virtual machine in which Confluence is running. (Refer to the full instructions.)

Property

Since

Default Value

Module...

Effect

atlassian.forceSchemaUpdate

1.0

true

atlassian-config

By default, Confluence will only run its database schema update when it detects that it has been upgraded. This flag will force Confluence to perform the schema update on system startup.

confluence.home

1.0

Any filesystem path

Confluence and atlassian-config

If this system property is set, Confluence will ignore the contents of the confluence-init.properties file, and use this property as the setting for the Confluence Home directory.

confluence.devmode

1.0

true

Confluence

Enables additional debugging options that may be of use to Confluence developers. Do not enable this flag on a production system.

confluence.disable.mailpolling

2.4

false

Confluence

If set to "true", will prevent Confluence from retrieving mail for archiving within spaces. Manually triggering "check for new mail" via the web UI will still work. This property has no effect on outgoing mail

confluence.i18n.reloadbundles

1.0

true

Confluence

Setting this property will cause Confluence to reload its i18n resource bundles every time an internationalised string is looked up. This can be useful when testing translations, but will make Confluence run insanely slowly.

confluence.ignore.debug.logging

1.0

true

Confluence

Confluence will normally log a severe error message if it detects that DEBUG level logging is enabled (as DEBUG logging generally causes a significant degradation in system performance). Setting this property will suppress the error message.

confluence.jmx.disabled

3.0

false

Confluence

If set to "true", will disable Confluence's JMX monitoring. This has the same effect as setting the "enabled" property to false in WEB-INF/classes/jmxContext.xml

confluence.optimize.index.modulo

2.2

20

Confluence

Number of index queue flushes before the index is optimised.

confluence.plugins.bundled.disable

2.9

false

Confluence

Starts confluence without bundled plugins. May be useful in a development environment to make Confluence start quicker, but since bundled plugins are necessary for some of Confluence's core functionality, this property should not be set on a production system.

atlassian.mail.fetchdisabled

1.0

false

atlassian-mail

Disables mail fetching services for IMAP and POP

atlassian.mail.senddisabled

1.0

false

atlassian-mail

Disables sending of mail

atlassian.disable.caches

2.4

true

atlassian-plugins, atlassian-cache-servlet

Setting this property will disable conditional get and expires: headers on some web resources. This will significantly slow down the user experience, but is useful in devlopment if you are frequently changing static resources and don't want to continually flush your browser cache.

org.osgi.framework.bootdelegation

2.10

empty

atlassian-plugins

Comma-separated list of package names to provide from application for OSGi plugins. Typically required when profiling Confluence. For example: "com.jprofiler.,com.yourkit.".

confluence.diff.timeout

3.1

1000

Confluence

Number of milliseconds to wait for a diff operation (comparing two page versions) to complete before aborting with an error message.

atlassian.user.experimentalMapping

2.10

false

Confluence

Setting this property changes the relationship between local users and local groups to reduce performance degradation when adding a local user to a local group with a large number of users. Please note, setting this property can slow down other user management functions. We recommend that you set it only if you are experiencing performance problems when adding local users to large local groups. Please refer to CONF-12319, fixed in Confluence 3.1.1.

confluence.import.use-experimental-importer

3.2

false

Confluence

Setting this property changes Confluence to use the Experimental XML Importer. It is designed to be a more stable implementation but, at the time of the release of 3.2, the importer is largely untested and thus not supported.
