Question

我在ms word上使用bi发布者加载项...当我试图在oracle apex 5.1中打印报告时出现错误 ORA-20001：无法访问打印引擎，因为指定的URL不正确或需要指定代理URL。因为我在堆栈溢出时发现了一些解决方案所以我试着在连接为sysdba

的sqlplus命令行上运行它

DECLARE
  ACL_PATH  VARCHAR2(4000);
BEGIN
  -- Look for the ACL currently assigned to '*' and give APEX_050100
  -- the "connect" privilege if APEX_050100 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_050100',
     'connect') IS NULL THEN
      DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(ACL_PATH,
     'APEX_050100', 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_050100', TRUE, 'connect');
  DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('power_users.xml','*');
END;
/
COMMIT;

DECLARE
  ACL_PATH  VARCHAR2(4000);
BEGIN
  -- Look for the ACL currently assigned to 'localhost' and give     APEX_050100
  -- 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_050100',
     'connect') IS NULL THEN
      DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(ACL_PATH,
     'APEX_050100', 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_050100', TRUE, 'connect');
  DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('local-access-users.xml','localhost');
END;
/
COMMIT;

执行后，我再次尝试打印报告，然后发生以下错误：

Error occurred while painting error page: ORA-01403: no data found ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1324 ORA-12570: TNS:packet reader failure

我该如何解决这个问题？

首先，ORA-20001是用户定义的错误。

我只重新订购了第一个街区。改变了陈述的顺序。在select语句之后放置异常。因为，当发生异常时，DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE不会在您的情况下运行。

DECLARE
  ACL_PATH  VARCHAR2(4000);
BEGIN
  -- Look for the ACL currently assigned to '*' and give APEX_050100
  -- the "connect" privilege if APEX_050100 does not have the privilege yet.
  BEGIN
      SELECT ACL INTO ACL_PATH FROM DBA_NETWORK_ACLS WHERE HOST = '*' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;

    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_050100', TRUE, 'connect');
             DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('power_users.xml','*');
  END;

  IF DBMS_NETWORK_ACL_ADMIN.CHECK_PRIVILEGE(ACL_PATH, 'APEX_050100',
     'connect') IS NULL THEN
      DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(ACL_PATH,
     'APEX_050100', TRUE, 'connect');
  END IF;
END;
/
COMMIT;
