从Oracle 10g迁移到11g驱动程序后无法打开连接

我有一个使用Oracle DB的应用程序，它使用c3p0和hibernate。 升级到Hibernate 4之后我得到了一个异常

建议的解决方案是将Oracle驱动程序从10g升级到11g。为此，我用ojdbc6.jar替换了ojdbc14.jar（实际上是ojdbc6_g.jar用于调试符号）。之后该应用程序不再启动异常

我从c3p0看不到任何东西，而不是Oracle 11g驱动程序。 它似乎是由于c3p0 0.9.2正在使用log4j而不是slf4j，所以在添加log4j-over-slf4j后我可以看到Oracle驱动程序抛出异常，c3p0正在记录为警告（原文如此！）

通过向启动JRE的命令提供参数-Duser.timezone=GMT可以解决此问题。但问题是为什么我在Linux上运行Java 8必须这样做？我的时区设置正确：

$ date +'%:z %Z'
+03:00 EEST

为什么我必须另外设置一个变量？

2 个答案:

答案 0 :(得分：1)

JDBC 11.2以后在连接到服务器时使用时区名称（通常从操作系统获得）。有很多原因可以解决这个问题，主要是为了避免在使用UTC的固定偏移量连接时发生的许多与DST相关的问题。

但是，如果数据库不理解时区id，则会抛出此错误。

有多种方法可以解决这个问题，最好的方法是将服务器更新为了解时区的版本，或使用最新的时区补丁修补现有服务器。

或者，通过在执行前在环境中设置TZ或使用-Duser.timezone = XXXX在JVM中更改它来更改客户端使用的时区。

最后，您还可以使用-Doracle.jdbc.timezoneAsRegion = false来恢复在连接上发送固定偏移量。建议不要这样做，因为它可能会重新引入不正确的DST相关行为。

答案 1 :(得分：0)

一切似乎都在客户端。 TimeZone.getDefault().getID()返回Europe/Helsinki。但是Oracle DB表V$TIMEZONE_NAMES不包含Europe/Helsinki，导致ORA-01882: timezone region not found异常。

需要将DSTv15 Timezone Patches应用于数据库以获取Europe/Helsinki。否则，必须在客户端明确设置-Duser.timezone=EET以避免此解决方案并遵循异常。
