Red Hat Enterprise MRG Messaging and Grid Version 1.1.1

Red Hat Enterprise MRG Messaging and Grid Update 1.1.1 is now available for
Red Hat Enterprise Linux 4.
This new release includes updated amqp, python-qpid, qpid-java,
qpidc, rhm and rhm-docs packages that fix bugs and add enhancements.

Red Hat Enterprise MRG (Messaging, Real-time and Grid) is a real-time IT
infrastructure for enterprise computing. MRG Messaging implements the
Advanced Message Queuing Protocol (AMQP) standard, adding persistence
options, kernel optimizations, and operating system services.

This update moves Red Hat Enterprise MRG to version 1.1.1 and includes
numerous bug fixes and enhancements.

Messaging enhancements include:

* The C++ and JMS clients and the qpidd broker now support full
SASL using the Cyrus library. This includes GSSAPI for authentication and
SASL negotiated security layers.

* The C++ and Java clients can now use heartbeats sent by the broker to
detect a failed connection/broker more rapidly.

* A new max-session-rate option has been added to qpidd to enable users to
set the maximum publication rate per session.

* A disaster recovery feature was added. Queue changes can now be
replicated from a data center to a passive replica at another site.

* Changes can now be made atomically for an incoming stream of messages
when a queue is bound with a given key in a direct exchange.

* New C++ API for interaction with the Qpid Management Framework

* Support has been added for Realtime threads in the JMS client.

Messaging bug fixes include:

* Several bugs relating to the stability of the persistence plugin for
qpidd were found and fixed.

* The qpid-config tool now correctly displays the LVQ_NO_BROWSE option for
queues on which that has been configured.

* A bug caused the broker to fail when a message without the required
header was sent to an LVQ. This has been corrected by ensuring that these
messages are handled as FIFO.

* A bug stopping the publication of events by a QMF agent was fixed.

Grid enhancements include:

* Remote configuration tools have been enhanced to allow listing of
configured nodes and explicit indication of default values during
configuration.

Grid bug fixes include:

* Periodic expressions are not evaluated by the JobRouter for managed
jobs. This provides the ability to stop routing jobs with systematic errors.

* The man and --help pages have been corrected to include a more accurate
description of the -name option arguments.

* A particular configuration was causing the condor_startd to stop working.
This error was resolved by causing the daemon to check for a NULL condition.

* Fixed memory leak in Condor's SOAP interface. Leak resulted in loss of
buffered data on each connection.

* Condor logs, lock files and run files are more tightly integrated with
Red Hat Enterprise Linux standards. Log files once found in ~condor/log/
are now available from /var/log/condor, and condor_master's pid file is
in /var/run/condor.

* Condor's init script was improved to remove an arbitrary 5 second delay
to allow for condor_master to shutdown. A delay is now only present if
the condor_master's shutdown is delayed.
