我必须在db2dsdriver.cfg中执行哪些规范才能连接到aDB2数据库？我得到SQL1532N错误

Question

我安装了Python 3.4和ibm_db来连接到DB2数据库;我在Python解释器中看到安装了ibm_db 2.0.7，但在连接到DB2数据库时，我收到了SQL1532N错误消息，因此我认为我需要配置db2dsdriver.cfg，并且为此我得到了db2dsdriver.xsd文件，但是我没有知道我必须改变什么。我应该将所有“数据库”更改为我尝试连接的DB2实例中数据库的实际名称？还有什么我必须改变？

顺便说一下，我的Windows 10中没有安装db2dsdriver.cfg，并且关于我认为它是从db2dsdriver.xsd动态创建的一些信息，它位于Python34下的\cfg子目录中。

Answer 1

的error message corresponding to SQL1532N写着：

的db2dsdriver.cfg中的配置文件中包含数据库别名 “数据库别名” 多个条目。

这可能意味着你做有db2dsdriver.cfg一个副本standard locations之一。根据您安装的驱动程序包，它可能在C:\ProgramData\IBM\DB2\<driver_copy_name or other path>\cfg之下。

.xsd文件描述了模式的配置文件，没有必要编辑它。您需要找到实际的.cfg文件并从中删除重复的数据库记录，只留下您需要的一个。
