ORoracle账号A-02069: global_names parameter must be set to TRUE for this operation
数据库中突然出现下面这样的错误：
ORA-02069: global_names parameter must be set to TRUE for this operation
https://forums.oracle.com/thread/472482
关于此的解答来自上面的论坛：
when global_names is TRUE, the database link name MUST be same as the global db name of the database to which the link connects to.
也就是说，如果global_names设置为true，那么目标数据库链路的名称也必须和数据库的全局名一样
我们再来看看，Oracle文档对这个错误的说明和建议：
[lubinsu@localhost ~]$ oerr ora 02069
02069, 00000, "global_names parameter must be set to TRUE for this operation"
// *Cause: A remote mapping of the statement is required but cannot be achieved
// because global_names should be set to TRUE for it to be achieved
// *Action: Issue alter session set global_names = true if possible
解决方法，alter session set global_names = true scope=both;
