Original Document Release
|
In 2007, the beginning and ending dates for Daylight Saving Time (DST) in the United States will change to comply with the Energy Policy Act of 2005. Under the new law, Daylight Saving Time will begin on the second Sunday of March and end on the first Sunday of November, extending the timeframe by four weeks. Due to this DST change, operating system and application software updates might be required to ensure that the system clock on HP products is accurate.
This is not unique to HP products. All devices that automatically adjust for Daylight Saving Time and support operating systems or software relying on a local time zone that observes DST will be affected by the 2007 DST change.

Several other countries, including Canada and Bermuda, are implementing the same DST change, and other countries are expected to make similar changes. For a complete listing of the World Wide Daylight Saving time schedule and which countries are changing DST schedules along with the US, go to the following URL:

SCOPE
This document outlines the actions needed for HP OpenView Storage Area Manager (HP OpenView SAM). For information on the US 2007 Daylight Saving Time Changes for HP products not addressed in this communication, go to the following URL:

DETAILS
Businesses and individuals whose environments are sensitive to date and time transactions and utilize a local time zone might be impacted by changes in the Daylight Saving Time rules. Some applications perform date and time manipulation and can make automatic decisions based on Daylight Saving Time rules.
Major operating systems, including HP-UX, Windows, Solaris, and Linux, are affected by changes in DST rules and have patches available. These patches can be obtained from your OS vendor. In addition, applications that depend on the Java Runtime Environment (JRE) are also affected because the JREs refer to inbuilt DST rules. Major JRE vendors have released an updater that can be used to update their installed JREs with the new DST rules.
HP OpenView SAM (OVSAM) is a Java based application that redistributes JREs whose DST rules do not comply with the United States Energy Policy Act of 2005. These non compliant JREs are deployed on the HP OpenView SAM Management Server, Client, Manager of Managers (MoM) and the Host Agents.
HP recommends that the entire OVSAM operating environment be updated with the new DST rules using vendor specific JRE updaters and patch updates to operating systems.
The impact of not updating or partially updating the OVSAM operating environment would result in inconsistencies in scheduled data collections, billing, reporting, event handling, and logging, where the actual execution or time reported will be one hour off from the time intended. This impact will be experienced only during three weeks in March and one week in November, starting in 2007.
For instructions on how to update the DST rules of JREs for your currently installed version of HP OpenView SAM, refer to Appendix - Instructions to update JREs redistributed by HP OpenView SAM, included below.
NOTE: The procedure for updating the JRE patches detailed in the appendix is applicable for both HP OpenView SAM 3.1 and HP OpenView SAM 3.2. However, for the JREs redistributed by HP OpenView SAM for HP-UX 11.20 and 11.23 on PA-9000 hosts for HP OpenView SAM 3.1, there are no DST updaters available.

Instructions to update IBM JRE redistributed by HP OpenView SAM on AIX Systems
These steps are applicable for Host Agent on 32-Bit AIX systems supported by HP OpenView SAM. For 64-Bit AIX systems, similar steps need to be followed using the IBM Time Zone Update Utility for Java - JTZU Version 1.1.7a - AIX PPC 64-bit (jtzu-aixppc64-1.1.7a.zip).
-
Download the
IBM Time Zone Update Utility for Java (JTZU Version 1.1.7a - AIX PPC 32-bit)
from
http://www-128.ibm.com/developerworks/java/jdk/dst/index.html.
-
Unzip the
jtzu-aixppc32-1.1.7a.zip
to a temporary location on the host on which the OpenView Storage Area Manager host agent is installed.
-
Open the script
runjtzenv.sh
in a text editor and make the following changes:
-
Change the line
JAVA_HOME=/*ENTER JAVA PATH UPTO JRE*/
to
JAVA_HOME=/opt/sanmgr/jre
-
Change the line
NOGUI=false
to
NOGUI=true
-
Open the file
DirectorySearch.txt
in a text editor.
-
Remove the existing lines and add the line
+/opt/sanmgr/jre
-
Execute the script
runjtzu.sh.
This will create a file
SDKList.txt
with the JRE that needs to be updated.
-
Open the file
runjtzu.sh
in a text editor and change the line
DISCOVERONLY=true
to
DISCOVERONLY=false
-
Execute the script
runjtzu.sh.
If the DST information in the JRE is older, it will update it with the timezone information with the new DST rules.
-
Restart the HP OpenView SAM Host Agent for the DST changes to take effect.
-
Repeat steps 2 to 9 for each system on which the JRE used by HP OpenView SAM needs to be updated.
