我工作的先端5，要运行先端双publihser报告。我创建的实例在管理实例>顶点主机地址的报表打印：本地主机端口：7001打印服务器：/ xmlpserver /转换

现在创建的报表查询，但是当我点击“测试报告查询”它为我的错误ORA-20001：打印引擎无法达到的，因为无论是指定的URL不正确或代理URL需要指定。

请帮我。

这个错误的原因是：

ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.

是因为默认情况下，与网络服务交互的能力被禁用Oracle Database 12c 。因此，如果你正在运行Oracle Application Express 5.0与Oracle Database 12c ，你必须使用新的DBMS_NETWORK_ACL_ADMIN包授予连接权限的任何主机的APEX_050000数据库用户。

因此，你应该授予连接的privilages到APEX_050000

解：

其中的Oracle Application Express安装为连接到数据库SYS指定SYSDBA角色。（由SYS连接到SQLPLUS以SYSDBA用户）

然后运行以下PLSQL：

DECLARE
  ACL_PATH  VARCHAR2(4000);
BEGIN
  -- Look for the ACL currently assigned to '*' and give APEX_050000
  -- the "connect" privilege if APEX_050000 does not have the privilege yet.

  SELECT ACL INTO ACL_PATH FROM DBA_NETWORK_ACLS
   WHERE HOST = '*' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;

  IF DBMS_NETWORK_ACL_ADMIN.CHECK_PRIVILEGE(ACL_PATH, 'APEX_050000',
     'connect') IS NULL THEN
      DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(ACL_PATH,
     'APEX_050000', TRUE, 'connect');
  END IF;

EXCEPTION
  -- When no ACL has been assigned to '*'.
  WHEN NO_DATA_FOUND THEN
  DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('power_users.xml',
    'ACL that lets power users to connect to everywhere',
    'APEX_050000', TRUE, 'connect');
  DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('power_users.xml','*');
END;
/
COMMIT;

该运行后：

DECLARE
  ACL_PATH  VARCHAR2(4000);
BEGIN
  -- Look for the ACL currently assigned to 'localhost' and give APEX_050000
  -- the "connect" privilege if APEX_040200 does not have the privilege yet.
  SELECT ACL INTO ACL_PATH FROM DBA_NETWORK_ACLS
   WHERE HOST = 'localhost' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;

  IF DBMS_NETWORK_ACL_ADMIN.CHECK_PRIVILEGE(ACL_PATH, 'APEX_050000',
     'connect') IS NULL THEN
      DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(ACL_PATH,
     'APEX_050000', TRUE, 'connect');
  END IF;

EXCEPTION
  -- When no ACL has been assigned to 'localhost'.
  WHEN NO_DATA_FOUND THEN
  DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('local-access-users.xml',
    'ACL that lets users to connect to localhost',
    'APEX_050000', TRUE, 'connect');
  DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('local-access-users.xml','localhost');
END;
