RHBA-2014:0803 - Bug Fix Advisory

Topic

Updated Messaging component packages that fix multiple bugs are now available
for Red Hat Enterprise MRG 2 for Red Hat Enterprise Linux 5.

Description

Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT
infrastructure for enterprise computing. MRG offers increased performance,
reliability, interoperability, and faster computing for enterprise customers.

MRG Messaging is a high-speed reliable messaging distribution for Linux based on
AMQP (Advanced Message Queuing Protocol), an open protocol standard for
enterprise messaging that is designed to make mission critical messaging widely
available as a standard service, and to make enterprise messaging interoperable
across platforms, programming languages, and vendors. MRG Messaging includes an
AMQP 0-10 messaging broker; AMQP 0-10 client libraries for C++, Java JMS, and
Python; as well as persistence libraries and management tools.

This update fixes multiple bugs. Documentation for these changes will be
available shortly from the Technical Notes document linked to in the References
section. All users of the Messaging capabilities of Red Hat Enterprise MRG 2.3
are advised to upgrade to these updated packages, which resolve the issues noted
in the Red Hat Enterprise MRG 2 Technical Notes. After installing the updated
packages, stop the cluster by either running "service qpidd stop" on all nodes,
or "qpid-cluster --all-stop" on any one of the cluster nodes. Once stopped,
restart the cluster with "service qpidd start" on all nodes for the update to
take effect.
