Weblogic 이나 Amberpoint 등등의 JVM 을 쓰는 플랫폼 기반에서 도는 어플리케이션들은 대부분 OS 타임을 읽지 않고 JAVA쪽 타임을 읽는군요..으아아악~~패닉 상태입니다..이거 다시 여기저기 engage 하려면 시간 걸리는데..이번주안에 완료 안되면 대형사고로 직결될수 있는~~~

다음은 Java.Sun 에서 캡춰한 부분입니다..

Updating the Java Runtime Environment With the Latest Timezone Data

Sun Microsystems makes every effort to ship each JRE update release with the most up-to-date Olson timezone data possible. Including current timezone data in each update of the JRE software, however, does not address earlier JRE releases that have already been installed and that are otherwise functioning adequately. The Java SE platform's timezone data is not read from the local or host operating system (OS), so OS timezone patches will not update the JRE software's timezone data. Consequently, older JRE releases might have outdated DST rules that have been superseded by changes in timezone boundaries or DST rules that are implemented after that release. As a result, applications running on an older JRE implementation in a region that has changed its DST rules might report the incorrect time after the date that the new DST rules were implemented. This can have serious consequences for software applications.

If you have installed the latest update release of the Java SE platform 6, or J2SE platform 5.0, 1.4.2 or 1.3.1, then you already have a recent version of the Olson timezone data. However, more recent Olson data that affects your timezone might have been released after the latest JRE update release. Consequently, if you are concerned about application failures that may result from any DST changes, you should perform the following steps:

1. Check which version of the Olson timezone data is included in your JRE version. See Timezone Data Versions in the JRE Software.
2. If the latest timezone data for your region is not in your JRE implementation, then update your JRE version with the most recent update release.
3. If the latest timezone data for your region is still not correct, then you should download and run the TZUpdater tool.

Ideally, installing the latest JRE update release is the preferred vehicle for delivering both timezone data updates and other product improvements, such as security fixes. However, if the timezone rules in your region change and you are unable to use the latest JRE update release, then you will need to update the platform's timezone data without altering other system configurations and dependencies. If for any reason you cannot upgrade your JRE software to the most recent update release, you can use a tool that can modify the timezone data within your existing JRE software without requiring you to update the whole platform. This tool, TZUpdater, updates older installed JRE implementations with the most recent timezone data.

The TZUpdater tool works on version 1.4 and later of the JRE software and on all the platforms that are supported by Sun. The tool is designed and built to provide full compatibility with any existing, previously installed JRE software on your system. For details of the latest release of the TZUpdater tool, see the TZUpdater README.

Even if you do upgrade to the latest update release of the JRE software, it is still possible that the latest timezone data for your region is not included. In this case, you should run the TZUpdater tool. See Timezone Data Versions in the JRE Software to see which version of the Olson timezone data is included in which JRE update release.

On Windows, Linux, and the Solaris 9 and Solaris 10 operating systems, the J2SE 1.3.1 platform completed the Sun End of Life (EOL) process when the Java SE 6 platform was released on December 11, 2006. A paid Java Vintage Support Offering is available for those customers who are interested in continued support for the 1.3.1 release. Please contact your Sun sales representative for details. On the Solaris 8 operating system, the J2SE 1.3.1 platform will continue in the EOL process until the the end of its five year Vintage Support Period in 2009. During this EOL transition period, products continue to be supported on Solaris 8 per existing customer support agreements.

However, customers with support contracts running the J2SE 1.3.1 platform can download a version of TZUpdater for JDK/JRE version 1.3.1 from the SunSolve Support Solutions site.

Customers using older Java platform versions that have completed the Sun EOL process, such as the 1.1 and 1.2 release families, should upgrade to a release family that is currently supported in order to obtain the latest DST rules. EOL products are not supported under standard support contracts. A paid Java Vintage Support Offering is available for those customers who are interested in continued support for a specific EOL release. Please contact your Sun sales representative for details.

한국은 썸머타임제가 없지만 미국이나 호주 등은 열심히 하고 있습니다.
이거 IT쪽 사람들에겐 골치거리 중에 하나입니다. 매번 3월 마지막주에 시간 변경이 있었는데..
이번년엔 4월 첫째주로 바뀌었네요...덕분에 Unix OS box 들은 전부 patch 깔고 reboot을 해야됩니다..

하필이면 이번엔 제가 코디네이션을 하게 되었는데요...
회사 내부적으로 사용하고 있는 130개 Application 에 의존성 가만해서 Reboot 스케쥴 잡고 Application 관리 개발부서 (저희부서)와 중형서버 관리부서간에 Implementation 계획을 수립해서 follow up 한다는게 장난이 아니네요..
분에 제가 Backend 에서 직접 지원하는 Application 말고 다른 Appl 도 전반적으로 볼수 있는 많은 기회가 되긴 합니다... 가장 문제가 되는 부분은 의존성이 가장 많은 SSO platform 인 Netegrity 나 Weblogic 기반에서 돌고 있는 Vignette 등등이 아닐까 하네요...에궁..잠시 중간에 머리 식히려고 주저리 주저리 해봅니다...

얼마전 요약해서 상관한테 보낸 메일 입니다.
아마도 BEA 전반에 관련된 Admin 업무가 추가 될듯 합니다..에궁..

FYI, I have surveyed Weblogic Server version 10 including 10.3 that will be released on June-2008.

Please refer to followings. I have summarized new features. :)

If you need further information including high level cost estimation to upgrade, please let me know.

Weblogic Server 10
