How to set serverTimeZone in Oracle JDBC database URL?

Question

I'm getting an error when I try to start a spring-boot application with Oracle connection:

csm-security              | 2022-06-29 19:26:21.571  INFO [csm-security,,] 1 --- [           main] w.s.c.ServletWebServerApplicationContext : Root WebApplicationContext: initialization completed in 2402 ms

csm-security              | ORA-01882: timezone region not found

I've tried to put useTimezone and serverTimezone on my application.properties but it didn't work:

spring.datasource.url=jdbc:oracle:thin:@192.1..1.1:1521:desastg?useTimezone=true&serverTimezone=UTC

I've also tried to put this:

spring.datasource.hikari.data-source-properties.oracle.jdbc.timezoneAsRegion=true

spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
spring.jpa.properties.hibernate.jdbc.time_zone=UTC

Answer 1

My server timezone was:

Command: timedatectl

Time zone: America/Argentina/Buenos_Aires (-03, -0300)

And in Oracle was:

Sql:SELECT DBTIMEZONE FROM dual;

+00:00

So I have to change on application.properties to put timezoneAsRegion to false:

spring.datasource.hikari.data-source-properties.oracle.jdbc.timezoneAsRegion=false

According to Oracle documentation when timezoneAsRegion is set to true it uses default JVM timezone rather than convert to a GMT offset.
