A Red Hat training course is available for Red Hat AMQ

Chapter 2. Enhancements

  • ENTMQBR-428 - Implement SASL external

    AMQ Broker can now validate AMQP connections by using the identity of the connection’s SSL certificate rather than using traditional credentials such as a username and password. This benefits deployments where secure access is managed through SSL certificates.

  • ENTMQBR-831 - Broker should respond to changes in logging.properties at run-time

    AMQ Broker now retains the changes that you make to the logging.properties configuration file without restarting the broker.

  • ENTMQBR-893 - Masking of password does not work with login.config

    You can now mask passwords in the JAAS configuration file login.config. Previously, password masking was not supported for login.config, which meant that the passwords in the file were stored in plain text.

  • ENTMQBR-908 - Support masked passwords in bootstrap.xml

    You can now mask passwords in the broker.xml configuration file. Previously, password masking was not supported for broker.xml, which meant that the passwords in the file were stored in plain text.

  • ENTMQBR-935 - Should have Ability to split broker.xml into multiple files and import into broker.xml

    AMQ Broker now supports XML inclusions in the broker.xml configuration file, which enables you to break broker.xml into separate files. For example, if you have multiple brokers that share the same set of addresses and address settings, you can define the addresses in a separate file, and then include that file in each broker’s broker.xml configuration file.

  • ENTMQBR-1056 - Add Support for DB2 v11.latest

    The 7.2 version of AMQ Broker adds support for the database DB2, version 11.

  • ENTMQBR-1063 - Improve DB2 compatibility

    AMQ Broker now supports IBM DB2 versions 10.5 and 11.1 for message storage. The following enhancements have been made:

    • AUTO_INCREMENT is now supported on DB2.
    • You can now configure the maximum allowed time difference between the system time and DB2 time. This makes high availability more reliable, because the broker will be shut down automatically if the time difference exceeds the configured value.
    • Database tables can now be created externally. Concurrent table creation checking has been improved.

  • ENTMQBR-1271 - Allow custom etc and data directories to be used

    AMQ Broker 7.2 provides greater flexibility in storing a broker instance’s configuration files and data. Previously, a broker instance’s configuration files and data could only be stored in the etc/ and data/ directories within the broker instance’s directory. Now, you can store these files in any custom directory, including locations outside of the broker instance’s directory.

  • ENTMQBR-1282 - Support for exclusive consumers

    AMQ Broker now supports exclusive queues. An exclusive queue routes messages to a single consumer even if multiple consumers are present. In addition, the consumer that receives the messages will receive them with guaranteed message ordering so that they can be consumed in the same order in which they were produced.

  • ENTMQBR-1308 - Create an ActiveMQServerPlugin for logging various broker events

    Starting in AMQ Broker 7.2, logging has been improved through a new LoggingActiveMQServerPlugin. By using this plugin, you can configure highly-informative logging about many different types of events that would otherwise only be available through debug logs.

  • ENTMQBR-1367 - Support SSL Certificate Revocation List

    Starting in AMQ Broker 7.2, you can now specify an SSL certificate revocation list on an acceptor’s URL. If you are using SSL for client communication, this means that you can specify a list of certificates that have been revoked by the issuing certificate authority (CA) before their scheduled expiration date and should no longer be trusted.

  • ENTMQBR-1370 - Add user attribute to queue in XML/JMX

    When a queue is auto-created it is assigned the user name of the connecting client. This user name is now exposed as metadata on the queue and also in JMX and in the AMQ Console. You can also now configure a user on a pre-defined queue by modifying the broker.xml file. This enhancement makes it possible to understand and track with whom and how queues originated.

  • ENTMQBR-1385 - Add support for virtual topic consumers

    AMQ Broker now supports migrating existing OpenWire clients that use virtual topic subscriptions (an ActiveMQ 5.x-only feature) without requiring any changes to the client. This functionality maps the virtual topic concept to an Artemis fully qualified queue name (FQQN). By using a FQQN, you can create and access a standard Artemis topic subscriber queue.

  • ENTMQBR-1403 - Support referrals in LDAP login module

    AMQ Broker now supports LDAP referrals. If you use LDAP referrals in your LDAP infrastructure, you can now configure the broker to use these referrals to authenticate and authorize users. You can use the broker’s JAAS LDAP login module to control how the broker handles LDAP referrals.

  • ENTMQBR-1918 - [AMQ7, critical-analyzer] add extra detail to output for analyzing cause of timeout

    The logs for the Critical Analyzer now provide extra information about a slow-performing broker when you enable tracing on the package named org.apache.activemq.artemis.utils.critical.

  • ENTMQBR-1974 - Support masked passwords in management.xml

    AMQ Broker now supports masking the values of the key-store-password and trust-store-password settings the in management.xml file. These values are used when you secure remote JMX access with SSL.

  • ENTMQBR-2020 - Track routed and unrouted messages to an address

    Address metrics now include information about how many messages the address has received. This number is divided between routed and unrouted messages. Prior to this enhancement, it was impossible to determine if an address had received a message which was not routed, for example, in the case of a JMS topic with no subscriptions.
