2014. Moscow goes back to winter

Not having found a more smart targets, we decided to return the Winter Time. So in the night of 25/26.10 Moscow will set time upon hour ago.

It is very joyful news for any Russian sysadmins which always waiting for a possibility to work in the weekends. It is the sarcasm.

My quick way for WAS admins and others.

OS update

Windows.
Install the update http://support.microsoft.com/kb/2998527
The update is installed without a restart.

Red Hat (CentOS), for other Linux (I don't use them) I think, the same.

Update tzdata files online, or download and install:

RH5: 
rpm -ivh --replacefiles tzdata-2014h-2.el5.x86_64.rpm
rpm -ivh --replacefiles tzdata-java-2014h-2.el5.x86_64.rpm 
RH6:
rpm -ivh --replacefiles tzdata-java-2014h-1.el6.noarch.rpm
rpm -ivh --replacefiles tzdata-2014h-1.el6.noarch.rpm

You can run the command for checking. If the result the same - it's OK. Otherwise you'll get nothing.

zdump -v Europe/Moscow |grep 2014 

Europe/Moscow  Sat Oct 25 21:59:59 2014 UTC = Sun Oct 26 01:59:59 2014 MSK isdst=0 gmtoff=14400

Europe/Moscow  Sat Oct 25 22:00:00 2014 UTC = Sun Oct 26 01:00:00 2014 MSK isdst=0 gmtoff=10800

Oracle Java update

Download http://www.oracle.com/technetwork/java/javase/tzdata-versions-138805.html

Unpack, stop Oracle, and run

./java -jar tzupdater.jar -u -v

java.vendor: Sun Microsystems Inc.
java.version: 1.5.0_30
JRE time zone data version: tzdata2011e

IBM Java update

Download https://www.ibm.com/developerworks/java/jdk/dst/jtzu.html
Unpack, stop all Java processes, (make executable for Linux), insert JAVA_HOME into runjtzuenv file and run runjtzu.

After that I used the second option with automatic search mode (Non-interactive mode).

You can use the small utility for checking your Java after updating (I made it using Integration Designer):

package ru.vl.checkDateTime;

import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

public class GetCurrentDateTime {
  public static void main(String[] args) {

       DateFormat dateFormat = new SimpleDateFormat("dd.MM.yyyy HH:mm:ss zzzz Z");
       //get current date time with Date()
       Date date = new Date();
       System.out.println(dateFormat.format(date));

       //get current date time with Calendar()
       Calendar cal = Calendar.getInstance();
       System.out.println(dateFormat.format(cal.getTime()));

  }
}

Before updating:

java -jar checkDateTime.jar

09.10.2014 12:08:06 Moscow Standard Time +0400
09.10.2014 12:08:06 Moscow Standard Time +0400

After:

/opt/ibm/bpm8/java/jre/bin/java -jar checkDateTime.jar
09.11.2014 12:04:28 Moscow Standard Time +0300
09.11.2014 12:04:28 Moscow Standard Time +0300

/u01/app/oracle/product/jdk/jre/bin/java -jar checkDateTime.jar
09.11.2014 12:04:47 Moscow Standard Time +0300
09.11.2014 12:04:47 Moscow Standard Time +0300

It works.
