 用dba账户使用下面脚本授予报错账户访问外部网络服务的权限，以SCOTT为例：

 1 BEGIN

 2 

 3   -- Only uncomment the following line if ACL "network_services.xml" has already been created

 4   --DBMS_NETWORK_ACL_ADMIN.DROP_ACL('network_services.xml');

 5 

 6   DBMS_NETWORK_ACL_ADMIN.CREATE_ACL(

 7     acl => 'network_services.xml',

 8     description => 'NETWORK ACL',

 9     principal => 'SCOTT',

10     is_grant => true,

11     privilege => 'connect');

12 

13   DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(

14     acl => 'network_services.xml',

15     principal => 'SCOTT',

16     is_grant => true,

17     privilege => 'resolve');

18 

19   DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL(

20     acl => 'network_services.xml',

21     host => '*');

22 

23   COMMIT;
