New Features in Message Queue 4.4.2

Message Queue 4.4.2 is a minor release that includes a number of feature enhancements and bug fixes. This section describes the new features included in this release.

• Message Queue now supports literal IPv6 addresses as broker host names when the hostname:port format is used. Previously, literal IPv6 addresses were only supported for the hostname format. If you use a literal IPv6 address, its format must conform to RFC2732, Format for Literal IPv6 Addresses in URL's.

• To address situations related to failover and restart of brokers in enhanced clusters, these features have been added:

  The -reset takeover-then-exit option of the imqbrokerd command

  The imq.cluster.ha.takeoverWaitTimeout broker property

• To provide more configurable control of connections to a JDBC data store, these broker properties have been added:

  imq.persist.jdbc.connection.timeoutIdle

  imq.persist.jdbc.connection.validateOnGet

  imq.persist.jdbc.connection.validationQuery

• To control generation of informational log messages about successful message transfers across a JMS bridge, the log-message-transfer attribute has been added to the jmsbridge element in the XML configuration file for a JMS bridge.

• To enable the STOMP bridge service to bind to a specific network interface, the imq.bridge.stomp.hostname broker property has been added.
