Hi everyone,
Does anyone know that the day light saving change have any impact on MQ application? We are running 5.0 or 5.2 and 5.3. I know there is not much we can do about 5.0. But I am not sure whether there are any patches to 5.2, or higher; whether MQ application gets the time from system, if that is the case, we should be fine since the server is already patched.
Any inputs are appreciated. |

Hummm...so for WebSphere MQ 6 is says to apply For US Time Zone Updates: Apply WebSphere MQ V6.0.2.0 refresh pack. I applied this about 2 months ago. I just downloaded it again and check the refresh pack to the one I downloaded 2 months ago and it seems to be the same.
So I'm okay then right?
Thanks,
Lex |

so I just checked and our servers are running the correct time; however our WMQ 6 environment is still an hour behind...refresh pack 2 has already been applied about a month ago.
anyone else see this yet? does mq need to be restarted?

Did you apply any of the OS DST patches ?

| Only strange thing we have seen so far is messages on a test environement coming up with some strange date...I believe it is something like 17 September 17,1729. We got this after an OS patch and we are still working on it....it is on Solaris MQ 6.0.1 coming from Z/OS. Messages are fine going to Z/OS and fine leaving. |

We didn't face any issues for MQ 6.0.2.0 and 5.3 , the logs reflecting the DST timings.
Thanks and Regards

Our servers had the MS DST patches applied and the server OS time was correct; however, Eclipse was still showing times one hour behind. I contacted IBM and it's the Eclipse JRE that needed to be updated. Here's there email support message to me:
| Code: |
Here are the instructions I mentioned in my voicemail..
The JVM that is installed with the Eclipse GUI needs to be updated using the JAVA Time Zone Utility (JTZU) tool...
Send me an email if you have any questions.. (websphere_support@mainz.ibm.com)..
Hello L2,
Customers need to ensure that the JRE being used by eclipse (which can be customized be customers) is up to date by running the JTZU against
the specified version that they are using. The actions that need to be
taken are as follows ....
- identify the JDK in use by eclipse
This is achieved by launching the WebSphere MQ explorer, and then
following the menu tree ...
Window ->Preferences -> Java -> Installed JREs
.
A list of one or more installed JREs are displayed in the panel.
One of these JREs will be 'checked' indicating that it is the one
that eclipse will use to run java code (MQ Explorer in this case)
against. Make a note of this location for example C:\JDK\J150
- Download and extract the appropriate JTZU from ...
.
http://www-128.ibm.com/developerworks/java/jdk/dst/index.html
.
- use the command and change directories to the extract location.
- alter the runjtzuenv.bat file to set the location of a JVM that the
tool will be launched under. for example...
rem set JAVA_HOME to the a Java installation directory
set JAVA_HOME=c:\jdk\j142\jre
rem set NOGUI
set NOGUI=false
rem set DISCOVERONLY
set DISCOVERONLY=true
rem set SILENTPATCH
set SILENTPATCH=false
This would instruct the tool to run against a JRE (in this case 1.4.2) at a location c:\jdk\j142\jre
- launch the tool using runjtzu.bat
- select 'Interactive mode' and click start button
- ensure customer make a note of the warning message regarding applying
maintenance
- enter the location of the java runtime being used by eclipse,
for example c:\jdk\J150\jre (please note that '\jre' is needed here)
- click update to begin the update process.
.
.
Customer should then re-test the MQExplorer and determine if the problem
persists.
