Updated Red Hat Enterprise MRG Realtime packages that add enhancements are nowavailable for Red Hat Enterprise MRG 2.5.

Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation ITinfrastructure for enterprise computing. MRG offers increased performance,reliability, interoperability, and faster computing for enterprise customers. MRG Realtime provides the highest levels of predictability for consistentlow-latency response times to meet the needs of time-sensitive workloads. MRGRealtime provides new levels of determinism by optimizing lengthy kernel codepaths to ensure that they do not become bottlenecks. This allows for betterprioritization of applications, resulting in consistent, predictable responsetimes for high-priority applications.This update provides bug fixes for the following packages: * The rt-setup package configures settings required by the Red Hat EnterpriseLinux real-time environment, such as creating the realtime group, addingrealtime user privileges to PAM (Pluggable Authentication Models), enabling theconfiguration of kdump in real time, and disabling the irqbalance daemon bydefault.* The rteval package contains a utility for measuring various aspects ofreal-time behavior on systems under load. The script unpacks the hackbenchstress test and benchmark utility, and the kernel source code from therteval-loads package, builds hackbench, and then goes into a loop, runninghackbench and compiling a kernel tree. During that loop, the cyclictest programis run to measure event response times. After the run time completes, astatistical analysis of the event response times is performed and printed to thescreen.This update adds the following enhancements:* MRG-Realtime stores release information in a database that is used to createthe 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 theMRG-Realtime releases. (BZ#1230400)* The rteval executable changed from using the libxslt library to the lxmllibrary from python and it caused the report generation to fail after a rtevalrun completed. The rteval specfile was modified to require the python-lxmlpackage which allowed the rteval report generation to succeed. (BZ#1241120)Users of the real-time capabilities of Red Hat Enterprise MRG 2.5, which islayered on Red Hat Enterprise Linux 6, are advised to upgrade to these updatedpackages which add this enhancement.
