    Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run the following command at a shell prompt: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. On the i686 architecture, *.i686.rpm packages should be installed where available rather than *.i386.rpm. If you are unsure which architecture you are on, run the following command at a shell prompt: rpm -q --qf '%{arch}\n' glibc Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory only contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://rhn.redhat.com/help/latest-up2date.pxt
