How to update time zone data in BW

There are two options to update time zone data

1. Update JRE

If there is a JRE update release that incorporates the updated time zone data, upgrade to that release. This is the approach recommended by Oracle.

Information on the time zone data in each JRE update release can be found in the release notes at the following links -

https://www.oracle.com/java/technologies/javase/11all-relnotes.html

There are a few different options to upgrade JRE -

a. Install TRA service pack release that includes the JRE update, if one is available.
b. Install TIBCO Supplement for Oracle Java release that includes the JRE update, if one is available.
c. Download the JRE update from Oracle and install the same (only for customers with an appropriate license from Oracle to download and use the update).
