ORA-01882: Timezone region not found
What it means
The time zone name is unknown to the server, or the client (JDBC driver) sends a region the database time zone file does not know.
How to fix it
Update the time zone file (DST patch), set the JVM -Duser.timezone to a known region, or use an offset like +02:00.
