Topic
Updated Red Hat Enterprise MRG Realtime packages that fix several bugs are now
available for Red Hat Enterprise MRG 2.4.
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 Realtime provides the highest levels of predictability for consistent
low-latency response times to meet the needs of time sensitive workloads. MRG
Realtime provides new levels of determinism by optimizing lengthy kernel code
paths to ensure that they do not become bottlenecks. This allows for better
prioritization of applications, resulting in consistent, predictable response
times for high-priority applications.
This update provides bug fixes for the following packages:
- The rt-setup package configures settings required by the Red Hat Enterprise
Linux real-time environment, such as creating the realtime group, adding
realtime user privileges to PAM (Pluggable Authentication Models), enabling the
configuration of kdump in real time, and disabling irqbalance by default.
- The rtctl package contains a set of scripts, which are used to manipulate the
scheduling priorities of groups of system threads.
Bug Fixes:
- MRG-Realtime stores release information in a database that is used to create
the contents of the file /etc/mrg-rt-release upon boot. The rt-setup package,
which manages this database, was updated with new information about the
MRG-Realtime releases. (BZ#1072588)
- MRG-Realtime creates a /etc/rtgroups file and a file per kernel,
/etc/rtgroups-<kernel>, to have more control of default priorities per kernel
version. Having the multiple files, however, can cause confusion. To address
this, the information contained on the manpage was enhanced and a header was
added to every configuration file explaining which MRG version and kernel set
this file has effect. This change should make easier to understand the current
behavior of the rtctl configuration files and make it simpler to identify the
right configuration file to use. (BZ#1061597)
Users of the real-time capabilities of Red Hat Enterprise MRG 2.4, which is
layered on Red Hat Enterprise Linux 6, are advised to upgrade to these updated
packages to resolve these bugs.
