All the items below must be validated:
A) Ensure the Operating System DST(Daylight Saving Time) start date is correct, on November 4, 2018 at 12:00 AM.
B) Ensure the JRE tzdata on the UIM machines have the update for DST change:
https://www.oracle.com/technetwork/java/javase/tzdata-versions-138805.html
The JRE tzdata version should be tzdata2018c or above.
Here are the steps to check the version and update the tzdata:
1) Download the Java Time Zone Updater Tool
https://www.oracle.com/technetwork/java/javase/downloads/index.html
2) Extract the Time Zone Updater 2.2.0 (tzupdater-2.2.0.zip) file and save the tzupdater.jar file in the C:\Program Files (x86)\Nimsoft\jre\jre8u102\bin\ directory
3) In a DOS-Prompt window as Administrator, navigate to the C:\Program Files (x86)\Nimsoft\jre\jre8u102\bin\ directory and run the following syntax to check the version of tzupdater.jar file:
java -jar tzupdater.jar -V
If the machine does not have access to the internet you will get the message above.
Regardless of the message, you will see the JRE tzdata version: tzdata2016d. (This version does not support the new DST change)
4) Download the file: tzupdater-2_2_0.zip from https://www.oracle.com/technetwork/java/javase/downloads/tzupdater-download-513681.html
and the tzdata2018g.tar.gz file from https://data.iana.org/time-zones/releases/ save it at C:\tmp\ directory of the UIM Server and UIM Portal Servers:
5) In a DOS-Prompt window as Administrator, navigate to the C:\Program Files (x86)\Nimsoft\jre\jre8u102\bin\ directory and run the following syntax to manually patch the installation with the tzdata2018g (timezone data):
C:\Program Files (x86)\Nimsoft\jre\jre8u102\bin>java -jar tzupdater.jar -l file:///C:/tmp/tzdata2018e.tar.gz
Successfully updated to tzdata2018g version.
If the UIM servers have access to the internet, you can run this syntax:
In a DOS-Prompt window as Administrator, navigate to the C:\Program Files (x86)\Nimsoft\jre\jre8u102\bin\ directory and run the following syntax to manually patch the installation with the tzdata2018f (timezone data):
C:\Program Files (x86)\Nimsoft\jre\jre8u102\bin>java -jar tzupdater.jar -l https://data.iana.org/time-zones/releases/tzdata2018f.tar.gz
Or
java -jar tzupdater.jar -l
Using https://data.iana.org/time-zones/releases/tzdata2018e.tar.gz as source for tzdata bundle.
6) Restart the Wasp probe from the UMP Portal Server
