Red Hat Enterprise MRG Grid 2.1 bug fix and enhancement update

Updated Grid component packages that add various enhancements and fix multiple
bugs are now available for Red Hat Enterprise MRG 2 for Red Hat Enterprise Linux
5.

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 Grid provides high-throughput computing and enables enterprises to achieve
higher peak computing capacity as well as improved infrastructure utilization by
leveraging their existing technology to build high performance grids. MRG Grid
provides a job-queueing mechanism, scheduling policy, and a priority scheme, as
well as resource monitoring and resource management. Users submit their jobs to
MRG Grid, where they are placed into a queue. MRG Grid then chooses when and
where to run the jobs based upon a policy, carefully monitors their progress,
and ultimately informs the user upon completion.

These updated packages for Red Hat Enterprise Linux 5 provide numerous
enhancements and bug fixes for the Grid component of MRG. Some of the most
important enhancements include:

* Inventory - integration of configuration management (wallaby) inventory into
the management console (cumin)

* Node grouping and feature application - integration of configuration
management tagging/feature application into the management console

* Performance and utilization - speedup in configuration management for saving
and activating configuration; increased utilization through improved re-use of
scheduler resources, signal escalation management and claim re-use; elimination
of expensive disk operations for parallel jobs

* Suspend and continue for jobs - ability to stop in place and later resume
jobs

* SSL security mechanism for the Aviary API

* Simplified configuration management database upgrades, via database patching
tool

* Availability of Cluster Suite managed HA of the scheduler

* Configuration management command-line tools from the wallaby shell, as
Technology Preview

* Operational Data Store command-line tools, as Technology Preview

* Cumin and Aviary integration, as Technology Preview

Space precludes documenting all of these changes in this advisory. Refer to the
Red Hat Enterprise MRG 2 Technical Notes document for information on these
changes:

All users of the Grid capabilities of Red Hat Enterprise MRG 2 are advised to
upgrade to these updated packages, which resolve the issues and add the
enhancements noted in the Red Hat Enterprise MRG 2 Technical Notes.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
