Purpose

RDBMS DSTv38 Patch 32327201 32327201 32327201 32327201 32327201 32327201 3232720132327201 32327201 32327201 32327201 32327201 32327201 32327201 32327201 32327201 32327201 32327
and OJVM DSTv38 Patch  are proactively done for all supported versions and platforms

There are no "PSU DST patches", for example, an Oracle DST patch for 11.2.0.4 can be applied using Opatch on *any* 11.2.0.4 PSU (same goes for any other Oracle RDBMS version)



Note that backports to versions that are NOT in Premier Support are possible/available for download only for customers with a valid Extended Support.
Exceptions for another version/platform combinations are only possible for customers with an existing Extended Support contract for the specific version/platform combination or platforms with an Extended Support Fee Waiver Period.


Please log an SR if you need a backport to such a platform/version (if you need several, log 1 SR clearly stating which version/platforms you have an Extended Support contract for and need ).
See Note 412160.1, section "G) For what versions are DST patches provided / there is no DST version X for my Oracle RDBMS version?"


Please consult your Sales representative to enroll in an Extended Support contract if required.

If you log an SR requesting a backport or the password for versions in Extended Support and there is no Extended Support contract in place the patch cannot be provided. 

 The RDBMS DSTv38 update includes the timezone information from the IANA ( http://www.iana.org/time-zones ) data  tzdata2022a.tar.gz and contains all previous Oracle RDBMS DST updates.

A complete overview of timezone updates is found in Note 412160.1 Updated DST Transitions and New Time Zones in Oracle RDBMS and OJVM Time Zone File Patches.

 The changes included in the DSTv38 patch (and not included in DSTv38) are listed below  

Changes included in tzdata2022a

Palestine will spring forward on 2022-03-27, not -03-26.
zdump -v now outputs better failure indications.
Bug fixes for code that reads corrupted TZif data.

   

Scope

 This note will give an overview of what checks to perform before applying the DSTv38 update.

 Note that all DST patches are always cumulative, which means they contain also ALL the previous DST changes/corrections. 

Please note that SYSDATE is NOT affected by "Oracle DST patches" seen SYSDATE is purely depending on the OS to get the time. So even an "unpatched database" will return a correct SYSDATE if the server (OS) time is correct.

For "sysdate" you do not need any DST patch  note 1627439.1 How to diagnose wrong time ( SYSDATE and SYSTIMESTAMP) after DST change , server reboot , database restart or installation when connecting to a database on an Unix server

For more information about Timestamp with (local) Time Zone please check Note 340512.1 Timestamps & time zones - Frequently Asked Questions
