RDBMS DSTv35 Patch 31335037 31335037 31335037 31335037 31335037 31335037 3133503731335037 31335037 31335037 31335037 31335037 31335037 31335037 31335037 31335037 31335037 31335037 31335037 and OJVM DSTv35 Patch are proactively done for all supported versions and platforms
There are no "PSU DST patches" , for example an Oracle DST patch for 22.214.171.124 can be applied using Opatch on *any* 126.96.36.199 PSU (same goes for any other Oracle RDBMS version)
Note that backports to versions who are NOT in Premier Support are possible / available for download only for customers with a valid Extended Support .
Exceptions for other version/platform combination are only possible for customers with an existing Extended Support contract for the specific version/platform combination or platforms with Extended Support Fee Waiver Period.
Please log a 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 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 a 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 DSTv35 update includes the timezone information from the IANA ( http://www.iana.org/time-zones ) data tzcode2020a.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 DSTv35 patch (and not included in DSTv34) are listed below
++ Canada's Yukon advanced to -07 year-round on 2020-03-08.
++ America/Nuuk renamed from America/Godthab.
++ zic now supports expiration dates for leap second lists.
This note will give an overview on what checks to perform before applying the DSTv35 update.
Note that all DST patches are always cumulative, which means they contain also ALL the previous DST changes / corrections.
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
