mysql - 从 Oracle 迁移到 MySql

Question

我想从 oracle 迁移到 MySql。我正在使用 MySql 迁移工具 5.0。 迁移向导中出了点问题。

错误信息是

两个 SQL 服务器都在本地主机上运行。

我该如何解决这些错误？

Answer 1

您可以将使用的服务名称添加到oracle数据库中，或者将输入的值'OracleServiceXE'修改为正确的值'XE'。输入的值看起来很像默认的 Windows 服务名称，可能会与 Oracle 数据库服务名称混淆。

将当前实例服务名称更改为 OracleServiceXE:

alter system set service_name = 'OracleServiceXE';

lsnrctl 服务

还应在 wards 后显示服务名称，除非数据库实例处于受限状态，在这种情况下使用服务名称的连接将失败。
