Change Oracle timezone tips

Oracle Database Tips by Donald BurlesonMay 2, 2016

Question: What do I do to change my Oracle timezone?  I need to change my Oracle timezone and I need to know what parameters to change.

Answer:  First, see my notes on Oracle timezone. To see your local time zone, enter:


 The time_zone is normally set at database creation time:

SQL> create database . . .     set time_zone='+00:00';

To change the Oracle time zone for an existing Oracle database, we change the time_zone parameter and then bounce the database.

SQL> alter database set time_zone = '-05:00';
SQL> shutdown immediate
SQL> startup

For OMS, log into the OMS repository as the SYSMAN user, the above command 'emctl resetTZ agent' tells you exactly what needs to be executed in the repository.

SQL> exec mgmt_target.set_agent_tzrgn('', 'Etc/GMT-6');
SQL> commit;
SQL> emctl start agent -- (or emctl start dbconsole)
