Quorum voting is used by both the live and the backup to decide what to do if a replication connection is disconnected.
Basically, the server will request each live server in the cluster to vote as to whether it thinks the server it is replicating to or from is still alive.
You can also configure the time for which the quorum manager will wait for the quorum vote response.
Currently, the value is hardcoded as 30 sec. We should change this 30-second wait to be configurable.
This option was removed in JRE 10 and its presence causes error on startup.
Artemis still does not compile on JDK 9 and up, so what I tried was
to compile on JDK 1.8 and then start Artemis on 1.8 and 10.
That now works for me.
It avoid using the system clock to perform the locks logic
by using the DBMS time.
It contains several improvements on the JDBC error handling
and an improved observability thanks to debug logs.
JdbcNodeManager is configured to use the same network timeout
value of the journal and to validate all the timeout values
related to a correct HA behaviour.
It allows a user to customize the max allowed distance between system and DB time,
improving HA reliability by shutting down the broker when the misalignment
exceeds configured limit.
The JDBC Lock Acquisition Timeout is no longer exposed to any user configuration and defaulted to infinite to match the behaviour of the journal (file-based) one.
Exclusive Queue documents added to detail behaviour and how to configure.
Also update docuents for last-value queue to cover addtional ways to configure
We provide a feature to mask passwords in the configuration files.
However, passwords in the bootstrap.xml (when the console is
secured with HTTPS) cannot be masked. This enhancement has
been opened to allow passwords in the bootstrap.xml to be masked
using the built-in masking feature provided by the broker.
Also the LDAPLoginModule configuration (in login.config) has a
connection password attribute that also needs this mask support.
In addition the ENC() syntax is supported for password masking
to replace the old 'mask-password' flag.
Apply fix so that when using JNDI via tomcat resource it works.
Replace original extract of JNDIStorable taken from Qpid, and use ActiveMQ5's as fits better to address this issue. (which primary use case is users migrating from 5.x)
Refactored ActiveMQConnectionFactory to externalise and turn into reference by StringRefAddr's instead of custom RefAddr which isnt standard.
Refactored ActiveMQDestinations similar
Refactored ActiveMQDestination to remove redundent and duplicated name field and ensured getters still behave the same
Openwire clients create consumers to advisory topics to receive
notifications. As a result there are internal queues created
on advisory topics. Those consumer shouldn't be exposed via
management APIs which are used by the Console
To fix that the broker doesn't register any queues from
advisory addresses.
Also refactors a code to remove Openwire specific contants
from AddressInfo class.
Added a new trustAll flag which will support trusting any client
keystore when doing testing against a broker. This setting should not
be used in production and is strictly for testing.
Update Tranformer to be able to handle initiation via propertiers (map<string, string>)
Update Configuration to have more specific transfromer configuration type, and to take properties.
Support back compatibility.
Add AddHeadersTransformer which is a main use case, and can act as example also.
Update Control's to expose new property configuration
Add test cases
Update examples for new transformer config style
- it is now possible to disable the TimedBuffer
- this is increasing the default on libaio maxAIO to 4k
- The Auto Tuning on the journal will use asynchronous writes to simulate what would happen on faster disks
- If you set datasync=false on the CLI, the system will suggest mapped and disable the buffer timeout
This closes#1436
This commit superseeds #1436 since it's now disabling the timed buffer through the CLI
* add Jolokia to the initial list of ways to access management API
* remove mentions of core queues, etc. (pre-addressing change)
* activemq.notifications can be consumed with any client
* activemq.management can be accessed only with Core or Core JMS clients
* *.management.*Control are interfaces, not classes
* remove ObjectNames from the summary of management methods.
IMO that made the short paragraphs hard to read.
And one can intuitively find them in jconsole,
or use the Builder class to construct them in code.
* move the note about empty filter to the queue management section
* add code snippet for creating ObjectName with ObjectNameBuilder
* mention web console and bin/artemis for interactive management
* fix few typos
delegate to the jdk saslServer. Allow acceptor configuration of supported mechanismis; saslMechanisms=<a,b>
and allow login config scope for krb5 to be configured via saslLoginConfigScope=x
Add extra configuration to address-settings to be able to
control / enable address/queue deletion by pattern,
rather than a global toggle.
Add support in the reload logic to remove address
and/or queues if the address matches an address setting,
where it is enabled.
Add topic and queue cache maps in Session.
Add configuration to use cache or not with defaulting to false, which keeps existing behaviour as the default.
the IntelliJ import wizard doesn't contain a sentence
like:"Select "Import from existing model".
This should be changed to "import project from external model" to be
conform and the IntelliJ IDEA version should be updated, too.
Added a wait-for-activation option to shared-store master HA policies.
This option is enabled by default to ensure unchanged server startup behavior.
If this option is enabled, ActiveMQServer.start() with a shared-store master server will not return
before the server has been activated.
If this options is disabled, start() will return after a background activation thread has been started.
The caller can use waitForActivation() to wait until server is activated, or just check the current activation status.
Broker should support full qualified queue names (FQQN)
as well as bare queue names. This means when clients access
to a queue they have two equivalent ways to do so. One way
is by queue names and the other is by FQQN (i.e. address::qname)
names. Currently only receiving is supported.

Adjust slow-consumer detection logic to use the number of messages in
the queue and not just the number of messages added since the last
check. This means the getRate() method now returns the rate of messages
which it *could* have dispatched since the last check rather than the
rate at which it received messages. This is a more reliable metric to
ensure the slow-consumer detection logic doesn't flag a consumer as
slow unfairly. Although the reliability will come at a performance cost
since getMessageCount() must lock the queue.
Currently there is no documentation about updating ActiveMQ Artemis in the Artemis user manual. This commit adds a brief description of the steps necessary to update Artemis to newer versions.
- user passwords for PropertiesLoginModule stored using PBKDF2 algothrim
by default
- implements cli user command to help create and manage user/roles
- adds a mask cli command to mask passwords
Adding instructions to set up test projects to work in eclipse that
depend on the unit-tests project. This is necessary so that the
generated logger can be found.
max-disk-usage = how much of a disk we can use before the system blocks
global-max-size = how much bytes we can take from memory for messages before we start enter into the configured page mode
This will also change the default created configuration into page-mode as that's more reliable for systems.
Implements a new feature for the broker whereby it may automatically create and
delete JMS topics which are not explicitly defined through the management API
or file-based configuration. A JMS topic is created in response to a sent
message or connected subscriber. The topic may subsequently be deleted when it
no longer has any subscribers. Auto-creation and auto-deletion can both be
turned on/off via address-setting.
using connector-name attribute got the following exception, -
'AMQ214019: Invalid configuration: org.xml.sax.SAXParseException; cvc-type.3.1.1: Element 'connector-ref' is a simple type,
so it cannot have attributes, excepting those whose namespace name is identical to
'http://www.w3.org/2001/XMLSchema-instance' and whose [local name] is one of 'type',
'nil', 'schemaLocation' or 'noNamespaceSchemaLocation'. However, the attribute, 'connector-name' was found.'
This feature required a bit of refactoring to the plugin interface itself as
well as a restriction on the configuration so that either only one plugin could
be specified or an ulimited number of security-setting matches. This was done
to prevent messy situations where a plugin could update settings from the XML
or even another plugin if there were overlapping matches.
Its now possible to also add the broker name to jmx tree avoiding clashes when multiple brokers are in a single vm. This is now the default but the old way can be used with some configuration

The failback process needs to be deterministic rather than relying on various
incarnations of Thread.sleep() at crucial points. Important aspects of this
change include:
1) Make the initial replication synchronization process block at the very
last step and wait for a response from the replica to ensure the replica has
as the necessary data. This is a critical piece of knowledge during the
failback process because it allows the soon-to-become-backup server to know
for sure when it can shut itself down and allow the soon-to-become-live
server to take over. Also, introduce a new configuration element called
"initial-replication-sync-timeout" to conrol how long this blocking will occur.
2) Set the state of the server as 'LIVE' only after the server is fully
started. This is necessary because once the soon-to-be-backup server shuts
down it needs to know that the soon-to-be-live server has started fully before
it restarts itself as the new backup. If the soon-to-be-backup server restarts
before the soon-to-be-live is fully started then it won't actually become a
backup server but instead will become a live server which will break the
failback process.
3) Wait to receive the announcement of a backup server before failing-back.
After I spent a whole afternoon trying to make IBM JDK to work under IDEA, I decided to add a note on the doc so other would have a chance to have it working faster than I did.
Lots of work on the test-suite in this commit including:
- Rename ServiceTestBase to ActiveMQTestBase
- Make AddressSettings fluent
- Remove unnecessary tearDown() implementations
- Use ActiveMQTestBase.create*Locator() instead of
ActiveMQClient.createServerLocator*(..)
- Use fluent ServerLocator methods
- Make sure all ActiveMQServers.newActiveMQServer invocations
are surrounded with addServer() where appropriate
- Create a few example tests to be references from hacking-guide
- Update hacking-guide with more info on writing tests
- Refactor config creation methods in ActiveMQTestBase
This has bothered me for awhile, but writing the hacking guide has
given me an opportunity to refactor some of our test-suite to be
simpler, more consistent, and easier to understand. This is
important if we want users to provide well-written tests. Our
test-suite is an important part of the code-base and it should be
easy to write good tests.
Basically I just consolidated CoreUnitTestCase, UnitTestCase, and
ServiceTestBase into a single class named ServiceTestBase. I also
simplified some of the configuration creation methods to reduce
duplicated code.
This is changing the default host to 0.0.0.0 per feedback from the community (activemq dev-list)
however if clustered is used some input or other properties will get input during the create process
I've also done some other changes based on some small issues I have encountered
https://issues.apache.org/jira/browse/ACTIVEMQ6-89
I have done a lot of refactoring on this. So we can a different version of the interceptor for each protocol based on a base class now.
Just an abstract class over Stomp would be a bit hacky... this is a better approach.
I also did some review of the huge table we have,
removed a few columns such as the datatype and
embedded the default on the description. Just trying to make easier to render and read
Also a few fixes on the doc context such as adding links and improving configuration-index
I - Removing note about deprecated properties. Our configs are using it
II - useNIO property is irrelevant since we always use NIO now with the new netty
I have changed the OpenOffice files. Exported the pictures
As I exported the pictures I selected the group on the slide,
File->Export, JPG file, and selected selection only.
The size was the default size and that worked alright.
