I believe what Jack's asking though is if the Java update is necessary, as updating Java on a server can have other impacts, especially if there's an Application Server on it.

Re: [Veritas-bu] NetBackup and New Daylight Saving Time Rules
I submitted a ticket with Symantec on this issue. Here is there response. John Stephens [EMAIL PROTECTED] == Known issues for the NetBackup Java Administration console (all versions): All currently supported versions of NetBackup (5.0, 5.1, 6.0) use the Java Runtime Environment (JRE) version 1.4.0 for the NetBackup Java Administration console. The JRE does not use the operating systems time zone database. Instead it has it's own implementation of time zone information and DST rules. Version 1.4.0 of the JRE does not contain the updated time zone information for 2007 and will cause the NetBackup Java Administration console to switch to DST on the wrong day. This will cause any reports in the NetBackup Java Administration console to report the wrong start and end times for jobs in the Activity Monitor. The NetBackup Java Administration also passes time zone information to other NetBackup commands such as bpplinfo, bpschedule, bpplsched, bppllist, and bpplschedrep using the -tzo setting. This can potentially impact the scheduling of backups. The upcoming NetBackup 6.5 release has an upgraded JRE version 1.4.2, which has accounted for the new DST rules. Hence this issue would not exist in NetBackup 6.5. There are workarounds to solve the problem for the NetBackup 6.0 and 5.x releases. Workarounds for known DST issues: There are two options for updating the JRE to properly handle the transition to and from daylight savings time. Option1: Using tools to update the JRE Time Zone Database There are tools available from Sun, IBM, HP to correct the time zone database in the Java Runtime Environment. It will be necessary to download and run this tool in order to update the NetBackup implementation of the JRE. For Solaris and Linux systems go to: http://java.sun.com/javase/tzupdater_README.html a) Under the Installation section select the link to the Sun Java SE download site b) On the downloads page select the JDK US DST Timezone Update Tool - 1.0 from the list to download the update tool. b) It will be necessary to log in using a valid Sun Online account to download. There is an option to register and create a new account if needed. c) Once you are logged in agree to the license, this is required to download the tool. d) Click on the Java(TM) 2 SDK, Standard Edition - US DST timezone tool 1.0.0 to download the tzupdater-1_0_0.zip file e) Extract the files to a temporary directory on the system. (ex. /tmp/javatz on Solaris and Linux, C:\javatz on Windows) f) Update the NetBackup implementation of the JRE. For Solaris and Linux systems: # cd /usr/openv/java/jre/bin # ./java -jar /tmp/javatz/tzupdater2006p/tzupdater.jar -u -v For Windows systems: % cd install_dir\VERITAS\Java\jre\bin % java -jar C:\javatz\tzupdater2006p\tzupdater.jar -u -v For AIX systems go to: http://www-128.ibm.com/developerworks/java/jdk/dst/index.html a) Click on the download link for the appropriate platform b) Extract the files to a temporary directory on the system (ex. /tmp/javatz) c) Edit the /tmp/javatz/runjtzuenv.sh file and set the configuration values JAVA_HOME=/usr/openv/java/jre NOGUI=false DISCOVERONLY=true d) Launch the IBM Time Zone Update Utility for Java. This is a GUI utility and the system DISPLAY setting must point to a valid system. # export DISPLAY=hostname:0 # sh /tmp/javatz/runjtzu.sh e) Select Interactive Mode and click Start f) Enter the location of the NetBackup implementation of the JRE (/usr/openv/java/jre/bin) and click Update g) Select Exit once the upgrade is complete For HP-UX systems go to: http://www.hp.com/products1/unix/java/DST-US.html a) Click on the JDK - TZupdater 1.0 link b) Accept the license and fill in the required contact information then click Finish c) Download the tzupdater_1.0.tar file d) Extract the files to a temporary directory on the system (ex. /tmp/javatz) e) Update the NetBackup implementation of the JRE. # cd /usr/openv/java/jre/bin # ./java -jar /tmp/javatz/tzupdater.jar -u -v For Tru64 platform, there are no tools available for updating the timezone database. There is no updated JRE available for this platform with the DST fixes. So Tru64 will continue to have the issue for 6.5 release as well. Hence the second workaround as suggested below will be the only way to resolve the problem for Tru64. Option2: Manually changing the DST through the Java GUI The following steps can be manually performed in the GUI to work around this issue: 1. Launch the NetBackup Java Administration console. 2. Go to File Adjust Application Time Zone... 3. Check the Use custom time zone box to set a custom time zone. 4. Verify the base time zone and offset are set correctly. These should be inherited from existing time zone. 5. Under the Daylight savings time starts section select Absolute date from the Use method: pull down. Then enter the correct
Re: [Veritas-bu] NetBackup and New Daylight Saving Time Rules
It's probably because Java is advertised as being platform independent. If you had a compile for an OS that didn't do DST (OS400 maybe?) it would be nice if the Java did.

Re: [Veritas-bu] NetBackup and New Daylight Saving Time Rules
