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
