All,
Last week, HP ran an on-line seminar regarding best practices for the changes to Daylight Saving Time. As part of the seminar, HP
supplied a small script for obtaining a system's DST readiness. It runs on HP-UX, Linux, and Tru64. It tests the OS readiness, Java
readiness, and on HP-UX supplies applications that could have aC++ issues. The software was released under the Open Software License
agreement and I checked with my local HP representative and he verified that it was okay to share the scripts with the user group.
The scripts ran as advertised on my HP-UX and Linux (Redhat/SuSE) systems and, with a little tweaking, I was able to run them on our
AIX and Solaris systems as well.
This script brought to light a number of issues in our environment including the fact that our RedHat servers were not ready to go! We
had applied the tztab patch but, on some of the servers, the patch did not automatically copy the timezone information from
/usr/share/zoneinfo/America/New_York to /etc/localtime! The issue, according to a Red Hat faq is as follows:
A caveat of only updating tzdata is there is no built in mechanism to update /etc/localtime to the latest timezone unless the
system is already running glibc-common version 2.3.2-95.40 or greater.
A link to the full article is here: http://kbase.redhat.com/faq/FAQ_79_9950
Anyway, I found this script to be of great value so I wanted to pass it on. Normally I would not include an attachment in a post, but
it's very small (24 KB) and since DST is less than two weeks away I thought it important to get this to everyone as soon as possible.
If this is a huge breach in etiquette I apologize in advance.
