Topic
Updated Red Hat Enterprise MRG Realtime packages that fix a number of bugs are
available for Red Hat Enterprise MRG 2.5.
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 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.
- The rtcheck package provides an application that tests the running system for
real-time capabilities. This program can be used by real-time-enabled programs
to determine if the environment they are in is suitable for them to run
correctly.
- 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 the irqbalance daemon by
default.
This update fixes the following bugs:
- Restarting rtcheck using "service rtcheck restart" failed because the
/lib/lsb/init-function was not installed. rtcheck now requires the
redhat-lsb-core package, which provides the missing library that allows rtcheck
to function correctly. (BZ#1169737)
- MRG-Realtime stores release information in a database that is used to create
the contents of the /etc/mrg-rt-release file upon boot. The rt-setup package,
which manages this database, has been updated with new information about the
MRG-Realtime releases. (BZ#1169496)
Users of the real-time capabilities of Red Hat Enterprise MRG 2.5, which is
layered on Red Hat Enterprise Linux 6, are advised to upgrade to these updated
packages.
