To see if you NEED DSTv30, please see the documents :
Mongolia no longer observes DST From 2017 - Impact on Oracle RDBMS (Doc ID 2288061.1)
Haiti Resumes DST in 2017 - Impact on Oracle RDBMS (Doc ID 2288041.1)
RDBMS DSTv30 Patch 25881255 and OJVM DSTv30 Patch 25881271 are proactively done for all supported versions and platforms
There are no "PSU DST patches" , for example an Oracle DST patch for 188.8.131.52 can be applied using Opatch on *any* 184.108.40.206 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 DSTv30 update includes the timezone information from the IANA ( http://www.iana.org/time-zones ) data tzdata2017b.tar 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 DSTv30 patch (and not included in DSTv29) are:
- Haiti resumed observance of DST in 2017
- Mongolia no longer observes DST.
- Chile's Region of Magallanes moves from -04/-03 to -03 year round, hiving off a new timezone America/Punta_Arenas.
Compared to DSTv29 this is the list of updated timezones in DSTv30 for non historical dates ( meaning update to the timezone after 1970):
This note will give an overview on what checks to perform before applying the DSTv30 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
