Oracle dbms_dst Database is using a timezone file older than version 11 tips

Oracle Database Tips by Donald BurlesonApril 12, 2015

Question:  I am on Oracle 11g and I get this message in my alert log:

Database is using a timezone file older than version 11.

What is the dbms_dst package and how to I use dbms_dst to change my timezone file?

Answer:  The dbms_dst package is used to adjust for daylight savings time.  You need to run dbms_dst when you see the "Database is using a timezone file older than version 11" message in your alert log. You can check your timezone value with this query:

select * from v$timezone_file;

If the timezone file does not say 11, then you run dbms_dst as per the  instructions in "Steps to Upgrade Time Zone File and Timestamp with Time Zone Data" in the Oracle Database 11g Globalization Support Guide.
