最近我们已经从Oracle 10g切换到了11g,只是现在我注意到我的邮件功能不起作用,我现在收到错误:
ORA-24247: network access denied by access control list (ACL)
所以我做了一些谷歌搜索,并且能够发现Oracle 11g中的新功能现在限制用户使用包括utl_smtp在内的某些软件包。因为我正在寻找一个快速的解决方案,所以我没有阅读Oracle文档,而是寻求更简单的解决方案并且遇到了本教程:
https://www.pythian.com/blog/setting-up-network-acls-in-oracle-11g-for-dummies/
我搞砸了一下,但因为我不知道更好,我想我添加了两个单独的配置.xml文件。所以我的问题的第一部分是 - 我如何删除它?
第二个问题是:
在向我的用户添加一些授权后,我尝试测试它是否有效,但我很快意识到它没有:
SELECT DECODE(
DBMS_NETWORK_ACL_ADMIN.check_privilege('netacl.xml', 'TEST1', 'connect'),
1, 'GRANTED', 0, 'DENIED', NULL) privilege
FROM dual;
返回:
PRIVILE
-------
DENIED
为什么?(这已被分类)
问题的第三部分 - 在阅读后被拒绝我尝试解决它:
BEGIN
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE('netacl.xml' ,'TEST1', TRUE, 'connect');
END;
但这给了我一个错误:
Ora19279 - XQuery dynamic type mismatch.....(more text meaning nothing to me).
为什么?(我已经说明了,当你第二次同时允许同样的错误时,就会出现错误)
更新
我已经按照下面的kevinsky的建议回答,并且在这个过程中学到了很多,但是我仍然有问题。我仍然得到ORA-24247:访问控制列表(ACL)拒绝网络访问。因为我按照建议做了其他一切,我开始认为问题可能是我添加的第一个配置文件,但现在无法删除,因为我记不起它的名字了。如果有人能帮助我,我会非常感激。
结果(我正在尝试一些不同的事情):
select * from dba_network_acls;
返回
* | 25 | 25 | /sys/acls/utl_smtp.xml| ACLID...
myservername.com | 25 | 25 | /sys/acls/utl_smtp.xml| ACLID...
myDBName | 25 | 25 | /sys/acls/utl_smtp.xml| ACLID...
mailServerDomainName | 25 | 25 | /sys/acls/utl_smtp.xml| ACLID...
mailserver.myDomain.local | 25 | 25 | /sys/acls/utl_smtp.xml| ACLID...
答案 0 :(得分:3)
我做了这次升级,这是工作时间。对于版本12,必须以不同方式重做。每个过程调用都必须具有提交。一般的想法是您创建访问权限,添加详细信息,授予权限。你必须知道:
/*create the access permission to connect*/
BEGIN
DBMS_NETWORK_ACL_ADMIN.create_acl (
acl => 'utl_smtp.xml',
description => 'access to smtp email',
principal => 'YourUser',
is_grant => TRUE,
privilege => 'connect',
start_date => SYSTIMESTAMP,
end_date => NULL);
COMMIT;
END;
--add the privilege to resolve names
BEGIN
DBMS_NETWORK_ACL_ADMIN.add_privilege (
acl => 'utl_smtp.xml',
principal => 'YourUser',
is_grant => TRUE,
privilege => 'resolve');
COMMIT;
END;
--assign your mailserver
BEGIN
DBMS_NETWORK_ACL_ADMIN.assign_acl (
acl => 'utl_smtp.xml',
host => 'mailserver.YourDomain.local',
lower_port => 25,
upper_port => NULL);
commit;
END;
BEGIN
DBMS_NETWORK_ACL_ADMIN.assign_acl (
acl => 'utl_smtp.xml',
host => 'YourDBName',
lower_port => 25,
upper_port => NULL);
COMMIT;
END;
--more housekeeping
alter system set smtp_out_server = 'mailserver.YourDomain.local:25' scope = both;
--make sure the user can access the smtp packages
GRANT EXECUTE ON UTL_TCP TO YourUser;
GRANT EXECUTE ON UTL_SMTP TO YourUser;
GRANT EXECUTE ON UTL_MAIL TO YourUser;
--check your work
select * from dba_network_acls;
--verify permissions for your user
SELECT DECODE(
DBMS_NETWORK_ACL_ADMIN.CHECK_PRIVILEGE(
'utl_smtp.xml', 'YourUser', 'resolve'),
1, 'GRANTED', 0, 'DENIED', NULL) PRIVILEGE
FROM DUAL;
--if you have created access permissions you wish to delete
--using the information from the select use this to delete what you don't want
exec DBMS_NETWORK_ACL_ADMIN.DROP_ACL ('acl_utl_smtp.xml');
