New DST and Java on VMS

[Dave Gudewicz]

Is there any VMS / Java specific information available regarding the upcoming DST changes?

Found references to Java on UNIX, but could not locate anything VMS related.

I understand that Java keeps its own time (someone here might confirm this) and therefore needs to have a patch applied to obey the new DST rules.

Hi Dave,

This link was posted by Kerry Main (HP) a few days ago.

Are you on the Encompass VMS sig mailing list?

Andy,

Yes I am on the Encompass list you mentioned but the page you (and Kerry) referenced is labeled "HP-UX 11.0 and 11i".

I did see this earlier this week and wondered it applied to VMS as well. Thus the question.

Has anyone here applied the referenced patch on a VMS system?

Took a quick look at the VMS java page here:

http://h18012.www1.hp.com/java/alpha/

Noticed that the kit version numbers are all of lower versions than the ones listed on the HP-UX 11.0 and 11i page and there is no mention of new DST rules.

Dave,

This is what I came up with by comparing the VMS Java release notes and from Sun's Java website their notes on the minimum versions that contain the new rules. It appears VMS has at least one version of Java on both platforms that contains the new time zone code.

Sun
Java SE6 or later
J2SE 5.0 update 6 or later (10 is the latest)
J2SE 1.4.2_11 or later (13 is the latest)
J2SE 1.3.1_18 or later (19 is the latest)

VMS Alpha Java
Java 1.3.1-7 based on Sun J2SDK 1.3.1_10 (No)
Java 1.4.2-5 based on Sun J2SDK 1.4.2_11 (Yes)
Java 5.0-2 based on Sun J2SE 1.5.0_06 (Yes)

VMS I64 Java
Java 1.4.2-3 based on Sun J2SDK 1.4.2_09 (No)
Java 5.0-2 based on Sun J2SE 1.5.0_10 (Yes)

Sun has a "TZupdater" on their download site for that can update the rules in Java 1.4 and above. HP appears to have a version of TZupdater for HPUX on the HPUX Java website.

The HP Service Tools (WEBES, ISEE, etc.) have even older JREs embedded in them.

Has anyone heard anything officially from HP on the state of the Java versions and/or the Service Tools?

I heard today from Kerry Main that an updated VMS/Java web page with DST information is in the works.

I logged a call with HP support, and they sent me this link:

Thomas,

That is the Sun web page I referenced in my earlier reply.

Ok, sorry about that. We're using V1.1.8-5 of the JAVA JRE. I'm trying to find out if we'll be affected, and if there's a workaround. I know that there's no patch available.
