Oracle 升级timezone version

1. timezone version 的背景

背景描述：

如果需要支持一个国际化的应用，那么数据库端的国际化特性的支持也就显得尤其重要。

Oracle中有很多特性支持国际化，如字符集、时区等等。如果相关参数设置不当，或者

由于对相关特性不够了解，以至于在设计阶段没有考虑完全，那么肯定会对应用造成一定

的损失

Database Time Zone只和TIMESTAMP WITH LOCAL TIME ZONE数据类型相关！其实数据库timezone

只是一个计算的标尺，TIMESTAMP WITH LOCAL TIME ZONE数据类型从客户端传入数据库后，转为

数据库时区存入数据库。在需要进行相关计算的时候，Oracle先把时间转换为标准时间(UTC)，

完成计算后再把结果转换为数据库时区的时间保存到数据库。

如果timezone version 不同会出现以下错误

Oracle TTS ORA-39322: Cannot use transportable tablespace with different timezone version

2. 如何查看，不同数据库版本的值是多少

数据库版本 11.2.0.1.0 SQL> select * from v$version; BANNER ------------------------------------------------------------------------------------------------------------------------ Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production PL/SQL Release 11.2.0.1.0 - Production CORE 11.2.0.1.0 Production TNS for Linux: Version 11.2.0.1.0 - Production NLSRTL Version 11.2.0.1.0 - Production 5 rows selected. SQL> SELECT NAME,VALUE$ FROM PROPS$ WHERE NAME='DST_PRIMARY_TT_VERSION'; NAME VALUE$ -------------------------------------------------- DST_PRIMARY_TT_VERSION 11 SQL> SELECT * FROM v$timezone_file; FILENAME VERSION -------------------- ---------- timezlrg_14.dat 11 数据库版本 11.2.0.4.0 SQL> select * from v$version; BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production PL/SQL Release 11.2.0.4.0 - Production CORE 11.2.0.4.0 Production TNS for 64-bit Windows: Version 11.2.0.4.0 - Production NLSRTL Version 11.2.0.4.0 - Production SQL> SELECT NAME,VALUE$ FROM PROPS$ WHERE NAME='DST_PRIMARY_TT_VERSION'; NAME NAME VALUE$ -------------------------------------------------- DST_PRIMARY_TT_VERSION 14 SQL> SELECT * FROM v$timezone_file; FILENAME VERSION -------------------- ---------- timezlrg_14.dat 14 数据库版本 12.2.0.1.0 SQL> select * from v$version; BANNER -------------------------------------------------------------------------------- CON_ID ---------- Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production 0 PL/SQL Release 12.2.0.1.0 - Production 0 CORE 12.2.0.1.0 Production 0 BANNER -------------------------------------------------------------------------------- CON_ID ---------- TNS for Linux: Version 12.2.0.1.0 - Production 0 NLSRTL Version 12.2.0.1.0 - Production 0 SQL> SELECT NAME,VALUE$ FROM PROPS$ WHERE NAME='DST_PRIMARY_TT_VERSION'; NAME VALUE$ -------------------------------------------------- DST_PRIMARY_TT_VERSION 26 SQL> SELECT version FROM v$timezone_file; VERSION ---------- 26

3 升级说明

根据当前timezone的版本，又分三种情况：

1）等于14：这已经是11g需要的版本了，所以升级前后都不需要做任何事，这种情况很罕见。

注意：11.2.0.1.0的timezone最高支持到11，可以通过升级数据库到11.2.0.3.0，将timezone升级到14

2）高于14：升级前，必须得给11g软件打上该timezone版本的DST补丁，这种情况也很罕见。

3）低于14：大多数都是这种情况，在升级前不需要在11g软件层面打补丁，在升级后需要再数据库层面将Timezone升级至14，具体看后面的步骤
