Issue/Introduction

Starting in 2019, the Daylight Summer Time (DST) will be decommissioned in Brazil.

This article explains how to configure your DSERIES environment for this change.

Environment

Release : 11.3.x,12.x

Component : CA WORKLOAD AUTOMATION DE (DSERIES)

Resolution

 

1- Before starting the procedure, ensure that the Operational System where DSERIES server is installed is patched accordingly:

 

2- Initially, you must patch the java JRE of DE server by doing the following:

a- Stop DE server service (If running in HA, stop standby server first);

Copy the "tzupdater.jar" file to <DE_server_install>\jre\bin directory;

OBS: The "tzupdater.jar" file is extracted from tzupdater-2_2_0.zip file, which can be downloaded from the following Oracle site:

https://www.oracle.com/technetwork/java/javase/downloads/index.html

b- Download the file attached on this article, rename it to "tzdata2019c-1.tar.gz" , then copy it to a temporary place (C:\temp\ (windows), or /tmp (Linux/Unix)).

c- From <DE_server_install>\jre\bin directory, run the following command:

(windows) java -jar tzupdater.jar -l file:///C:\temp\tzdata2019c-1.tar.gz -v -f

(linux) java -jar tzupdater.jar -v -l file:///tmp/tzdata2019c-1.tar.gz -v -f

d- Start DE server (If running in HA, start primary server first);

3- Then, you must patch the java JRE of Desktop Client by doing the following in the machine where it is installed:

a- Copy the "tzupdater.jar" file to "<Desktop_client_install>\jre\bin\" directory;

b- Copy the "tzdata2019c-1.tar.gz" file (attached in this article), to "C:\temp\" directory;

c- From <Desktop_client_install>\jre\bin\ directory, run the following command:

java -jar tzupdater.jar -l file:///C:\temp\tzdata2019c-1.tar.gz -v -f

4- (OPTIONAL) You can also patch the java JRE of the Workload System Agents in your environment. The only expected impact of not doing this, is that the agent logs timestamps will be stamped 1 hour ahead of the server during the old DST period (from november to february). No other impacts are expected for workload server.

a- Stop agent service;

b- Copy the "tzupdater.jar" file to <agent_install>\jre\bin directory;

c- Copy the "tzdata2019c-1.tar.gz" file (attached in this article), to C:\temp\ (windows), or /tmp (Linux/Unix);

d- From <agent_install>\jre\bin directory, run the following command:

(windows) java -jar tzupdater.jar -l file:///C:\temp\tzdata2019c-1.tar.gz -v -f

(linux) java -jar tzupdater.jar -v -l file:///tmp/tzdata2019c-1.tar.gz -v -f

e- Start agent service;
