Latest DSTv17 Timezone Patches Available for E-Business Suite R12

Hourglass iconIf your E-Business Suite Release 11i or 12 environment is configured to support Daylight Saving Time (DST) or international time zones, it's important to keep your timezone definition files up-to-date. They were last changed in August 2011 and released as DSTv16.

DSTv17 is now available and certified with Oracle E-Business Suite Release 12. The DSTv17 update includes the timezone information from Olson tzdata 2011j. 

DSTv17 is an interim release.  Its primary purpose is to include the new DST rules for Russia which take effect from 30th October 2011.  At this time the clocks will not move back one hour but will remain on "summer time" instead.

Patches for this release are available on a request-only basis.  If you require this patch for your operating system/patch configuration, you must request it explicitly from Oracle Support.

Is Your Apps Environment Affected?

When a country or region changes DST rules or their time zone definitions, your Oracle E-Business Suite environment will require patching if:

  • Your Oracle E-Business Suite environment is located in the affected country or region OR
  • Your Oracle E-Business Suite environment is located outside the affected country or region but you conduct business or have customers or suppliers in the affected country or region

We last discussed the DSTv16 patches on this blog. The latest DSTv17 timezone definition file is cumulative and includes all DST changes released in earlier time zone definition files. DSTv17 includes changes to the following timezones since the DSTv16 release:

  • Africa/Nairobi,
  • Africa/Dar_es_Salaam,
  • Africa/Kampala,
  • America/St_Johns,
  • America/Goose_Bay,
  • America/Resolute,
  • Asia/Yekaterinburg,
  • Asia/Omsk,
  • Asia/Novosibirsk,
  • Asia/Krasnoyarsk,
  • Asia/Irkutsk,
  • Asia/Yakutsk,
  • Asia/Vladivostok,
  • Asia/Magadan,
  • Asia/Kamchatka,
  • Asia/Anadyr,
  • Asia/Sakhalin,
  • America/Metlakatla,
  • Europe/Kaliningrad,
  • Europe/Moscow,
  • Europe/Samara,
  • Europe/Volgograd,
  • Pacific/Apia,
  • Canada/Newfoundland,
  • W-SU

What Patches Are Required?

In case you haven't been following our previous time zone or Daylight Saving Time (DST)-related articles, international timezone definitions for E-Business Suite environments are captured in a series of patches for the database and application tier servers in your environment. The actual scope and number of patches that need to be applied depend on whether you've applied previous DST or timezone-related patches. Some sysadmins have remarked to me that it generally takes more time to read the various timezone documents than it takes to apply these patches, but your mileage may vary.

We've published the following Notes which identify the various components in your E-Business Suite environment that may need DST patches:

What happened to EBS 11i?

The certification of DST v17 with Oracle E-Business Suite Release 11i is still in progress.  Oracle's Revenue Recognition rules prohibit us from discussing certification and release dates. You're welcome to monitor or subscribe to this blog for updates, which I'll post as soon as soon as they're available.

Given the importance of the Olson time zone database to Oracle Apps (and heck, Oracle in general), are there plans for Oracle to host its own Olson time zone database since Olson no longer supports the time zone database?

Apparently I might have missed something in my news feed - it appears ICANN announced today it is taking over the Olson time zone database.

Still, given that Oracle (and its customers) relies on the tzdata and Oracle has two of it's own operating systems (OL, Solaris)...

Anyhow, more info

As always, thanks to Steven and the EBS Development group for this blog to keep us informed about DST patches and such!
