In order to prepare a development web server running Redhat Linux 9 for 2007 DST changes, I upgraded its glibc from 2.3.2-27 to 2.3.2-71 to take advantage of tzdata rpm packages updated for 2007 DST changes.

• glibc-2.3.2-64 is the earliest version of glibc RPM that has separated timezone data into a new rpm named tzdata (More details can be found here).
• A backend Sybase ASE server also runs RHL 9, but with a newer glibc-2.3.2-71. The latter was recommended by Michael Peppler for Sybase ASE 12.5 on RHL9 to get around certain bugs in the glibc RPM package shipped with the original RHL9. Read the rest of this entry »

In my previous post, I theorized that tzdata RPM from FC1 (Fedora Core 1) updates repository would be useful to prepare old Linux systems such as RHL 9 (redhat Linux 9) or older, without having to upgrade glibc and glibc-common packages. It turned out that the original RHL 9 release had /usr/share/zoneinfo as part of glibc rpm package. It remains to be the case unless glibc rpm is upgraded to version 2.3.2-64 (Mon Jul 28 2003) or newer. Therefore, the glibc actually does need to be upgraded to at least 2.3.2-64, to take advantage of the steps to prepare older Linux systems for 2007 DST changes using an updated tzdata rpm as discussed in an earlier post.
