方法一： jingtai = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.111)(PORT = 1523)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = prod.enmoedu.com)——取自global_name，可以理解为service_name等同于global_name ) ) global_name又是来自Db_name. Db_domain 要修改global_name，执行ALTER DATABASE RENAME GLOBAL_NAME TO <db_name.db_domain> 方法2： jingtai2 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.111)(PORT = 1523)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SID = prod)——取自instance_name； ) )
