【问题描述】:
出于培训目的,我正在尝试在 Oracle 12c 和 Cassandra 3.9.0 之间创建一个 DBLink,两者都安装在本地计算机上。
为此,我执行了link 中描述的步骤。 不幸的是,最后我完成了错误消息:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
Unable to retrieve columns for table [LOCAL]. {42000,NativeErr = -1}
ORA-02063: preceding 2 lines from TO_CASSANDRA
28500. 00000 - "connection from ORACLE to a non-Oracle system returned this message:"
*Cause: The cause is explained in the forwarded message.
*Action: See the non-Oracle system's documentation of the forwarded
message.
请给我一些关于我做错了什么的提示吗?
谢谢,
