acl使用示例

declare
  v_count  number;
  uprinciple varchar2(20);
  principle  varchar2(20);
 
begin

uprinciple := upper('&wssl_user');
select count(1)  into v_count from dba_network_acls where acl like '%httprepuestpermission01.xml%';

if v_count <> 0 then
   dbms_network_acl_admin.drop_acl(acl=> 'httprepuestpermission01.xml');
      commit;

end if;
--1.0 创建 ACL 以及相关操作
  dbms_network_acl_admin.create_acl(acl         => 'httprepuestpermission01.xml',
                                    description => 'Network permissions',
                                    principal   => uprinciple,
                                    is_grant    => TRUE,
                                    privilege   => 'connect',
                                    start_date  => systimestamp,
                                    end_date  => null);
commit;

--1.1 授予普通用户可以使用ACL的权限  
  dbms_network_acl_admin.add_privilege(acl        => 'httprepuestpermission01.xml',
                                       principal  => uprinciple, --要使用acl的用户
                                       is_grant   => true,
                                       privilege  => 'connect',
                                       start_date => systimestamp,
                                       end_date   => null);
                                      commit;

--1.2授予普通用户可以使用ACL的权限
  dbms_network_acl_admin.assign_acl(acl        => 'httprepuestpermission01.xml',  
                                      host       => '&url_ip',      --要访问的目标主机
                                      lower_port => &url_port,                 --要访问的端口
                                      upper_port => &url_port);  
                                      commit;

end;
