【问题描述】：
我们计划安装UTL_MAIL 软件包，目前正在我们的开发环境中测试安装步骤。
在成功安装UTL_MAIL 包脚本并创建足够的PUBLIC 同义词和授权后，
我们在运行下面的测试匿名块时收到错误ORA-29278：
BEGIN
UTL_MAIL.SEND(sender => 'xxx@oracle.com'
, recipients => 'Migs.Isip.23@gmail.com'
, subject => 'Testmail'
, message => 'Hello');
END;
错误消息的详细信息：
ORA-29278: SMTP transient error: 421 4.3.2 Service not available
ORA-06512: at "SYS.UTL_MAIL", line 662
ORA-06512: at "SYS.UTL_MAIL", line 679
ORA-06512: at line 3
29278. 00000 - "SMTP transient error: %s"
*Cause: A SMTP transient error occurred.
*Action: Correct the error and retry the SMTP operation.
根据相关链接 (Send Email Using PLSQL) 的研究， 我可能需要设置正确的访问控制列表 (ACL) 才能正常工作。但是，在执行下面的脚本时，我仍然遇到同样的错误。
DECLARE
-- ACL name to be used for email access reuse the same value for all
-- future calls
l_acl VARCHAR2 (30) := 'utl_smtp.xml';
-- Oracle user to be given permission to send email
l_principal VARCHAR2 (30) := 'APPS';
-- Name of email server
g_mailhost VARCHAR2 (60) := 'smtprelay.xxxxx.com';
l_cnt INTEGER;
PROCEDURE validate_smtp_server
AS
l_value v$parameter.VALUE%TYPE;
l_parameter v$parameter.name%TYPE := 'smtp_out_server';
BEGIN
SELECT VALUE
INTO l_value
FROM v$parameter
WHERE name = l_parameter;
IF l_value IS NULL
THEN
raise_application_error (
-20001
, 'Oracle parameter '
|| l_parameter
|| ' has not been set'
|| UTL_TCP.crlf
|| 'it s/b smtprelay.alorica.com'
);
END IF;
DBMS_OUTPUT.put_line ('parameter ' || l_parameter || ' value is ' || l_value);
END validate_smtp_server;
PROCEDURE create_if_needed (p_acl IN VARCHAR2)
AS
l_cnt INTEGER;
BEGIN
SELECT COUNT (*) c
INTO l_cnt
FROM dba_network_acls a
WHERE SUBSTR (acl, INSTR (acl, '/', -1) + 1) = p_acl;
IF l_cnt = 0
THEN
DBMS_OUTPUT.put_line ('creating acl ' || p_acl);
DBMS_NETWORK_ACL_ADMIN.create_acl (
acl => p_acl
, description => 'Allow use of utl_smtp'
, principal => l_principal
, is_grant => TRUE
, privilege => 'connect'
);
DBMS_NETWORK_ACL_ADMIN.assign_acl (acl => p_acl, HOST => g_mailhost);
COMMIT;
ELSE
DBMS_OUTPUT.put_line (p_acl || ' acl already exists');
END IF;
END create_if_needed;
PROCEDURE add_if_needed (
p_principal IN VARCHAR2
, p_acl IN VARCHAR2
)
AS
l_cnt INTEGER;
BEGIN
SELECT COUNT (*) c
INTO l_cnt
FROM dba_network_acl_privileges
WHERE SUBSTR (acl, INSTR (acl, '/', -1) + 1) = p_acl
AND principal = p_principal;
IF l_cnt = 0
THEN
DBMS_NETWORK_ACL_ADMIN.add_privilege (
acl => 'utl_smtp.xml'
, principal => p_principal
, is_grant => TRUE
, privilege => 'connect'
);
COMMIT;
DBMS_OUTPUT.put_line ('access to ' || p_acl || ' added for ' || p_principal);
ELSE
DBMS_OUTPUT.put_line (p_principal || ' already has access to ' || p_acl);
END IF;
END add_if_needed;
BEGIN
EXECUTE IMMEDIATE 'grant execute on utl_mail to ' || l_principal;
create_if_needed (p_acl => l_acl);
add_if_needed (p_principal => l_principal, p_acl => l_acl);
DBMS_OUTPUT.put_line ('Verification SQL:');
DBMS_OUTPUT.put_line (' SELECT * FROM dba_network_acls;');
DBMS_OUTPUT.put_line (' SELECT * FROM dba_network_acl_privileges;');
COMMIT;
validate_smtp_server;
END;
为此我还可以采取哪些其他步骤或需要向 DBA 提供哪些其他说明？
Oracle 数据库版本：
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
PL/SQL Release 11.2.0.4.0 - Production
"CORE 11.2.0.4.0 Production"
TNS for Solaris: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production
非常感谢。
