我們計劃安裝UTL_MAIL
軟件包,目前我們正在測試開發環境中的安裝步驟。 後成功地安裝UTL_MAIL
包裝腳本和創建充分PUBLIC
同義詞和資助, 運行測試時,我們所得到的是錯誤ORA-29278
匿名塊如下:ORA-29278:SMTP瞬態錯誤:運行UTL_MAIL時服務不可用
BEGIN
UTL_MAIL.SEND(sender => '[email protected]'
, recipients => '[email protected]'
, subject => 'Testmail'
, message => 'Hello');
END;
錯誤消息的
的詳細介紹:
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.
根據相關鏈接研究(Send Email Using PLSQL), 我可能需要設置正確的訪問控制列表(ACL)才能使其工作。但是,在執行下面的腳本時,我仍然得到相同的錯誤。
DECLARE
-- ACL name to be used for email access reuse the same value for all
-- future calls
l_acl VARCHAR2 (30) := 'utl_smtp.xml';

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

IF l_value IS NULL
THEN

, 'Oracle parameter '

|| UTL_TCP.crlf

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)

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 (

DBMS_OUTPUT.put_line (' SELECT * FROM dba_network_acls;');

我可以採取哪些其他步驟或需要向DBA提供哪些其他說明?
Oracle數據庫版本:
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
非常感謝你。
嗨,我面臨與我的應用程序類似的問題。我無法發送電子郵件,而且我在公司網絡內。我想更深入地與你討論。我也得到「SMTP瞬態錯誤:421服務不可用」。 –
@RaviShankar你還在使用PL/SQL嗎? –
是的!我正在使用PL/SQL。 –
