ORA-23327: imported deferred rpc data does not match string of importing db
Cause: Deferred rpc queues were imported from a database with a different global name or operating system than importing database.
Action: Deferred rpc data should only be imported into a database with the same global name and hardware and operating system.
ORA-23327 错误是一个延迟的远程程序调用（RPC）表示引入的RPC数据与导入数据库的字符串不匹配的报错，它会在将远程程序调用导入本地数据库时出现。ORA-23327常在导入导出（import/export）或使用exp/imp注册RPC时报出。
常见的案例是：当试图在现有的日志文件或dmp文件的基础上操作RPC时，ORA-23327经常会出现。
