oracle数据库修改时区

1、查看当前数据库时区

SQL> select dbtimezone from dual; DBTIMEZONE ------------ +00:00

2、查看会话时区

SQL> select sessiontimezone from dual; SESSIONTIMEZONE -------------------------------------------------------------------------------- +08:00

可以看到会话时区是北京时区。和数据库 时区不一致。

3、修改数据库的时区为CST

alter database set time_zone='+8:00'; SQL> alter database set time_zone='+8:00'; Database altered.

4、重启数据库

SQL> shutdown immediate Database closed. Database dismounted. ORACLE instance shut down. SQL> startup ORACLE instance started.

SQL> select sessiontimezone, dbtimezone from dual; SESSIONTIMEZONE -------------------------------------------------------------------------------- DBTIMEZONE ------------ +08:00 +08:00
