今天一个10g的客户端，连接12c的数据库，报错：

而这个客户端连接其他12c的数据库是没有问题的。
这是因为建立的service已经是非标准的service，包含了failover type等参数。见下面的Test Case：

该问题是Bug 8599395 : EZCONNECT ERRORS WITH SP2-0642: SQL*PLUS INTERNAL ERROR STATE 2130, CONTEXT 0:0:
解决方法：
建议升级客户端到11.2以上，或者按照bug文档中的workaround也可以：

1 2 3 4 5 |
Workaround: ----------- LOCAL naming resolution works -- 使用tnsnames.ora文件连接 Use standard service works -- 使用标准的service，去掉failover type的参数设置 Do not put port number in the command -- 使用1521默认端口，ezconnect的时候，不写端口号 |
