Kirill Loifman Often in a complex enterprise Infrastructure Oracle DBAs face issues by enabling SMTP mail traffic on the databases through corporate email gateway servers. Imagine you have to provide your database applications an ability to send emails via Simple Mail Transfer Protocol SMTP protocol from Oracle database. Below I give a detail action plan to accomplish the same. My test example includes an Oracle database 1. R2 running on Linux Red. Hat 6 and a Microsoft Exchange corporate server. Oracle packages SYS. UTLSMTP and SYS. UTLTCPCheck if Oracle packages SYS. UTLSMTP and SYS. UTLTCP are available on Oracle database and you have EXECUTE grants on them. Check SMTP access of database Linux server on mail server Check whether you are able to contact the email gateway server via SMTP from the database Linux box telnet smtpserver 2. If you see blank screen or an error telnet Unable to connect to remote host Connection refused,your DB server is not recognized by the SMTP server. In this case you have to apply for mail SMTP access. Otherwise type the following commands to test sending email from Linux to your corporate email account. Sender OK. rcpt to myemailmycompany. Kp System Astrology Software. Recipient OK. data Start mail input. SMTP and orcl DB. Apply for mail SMTP access. Contact your mail exchange admins and apply for SMTP access on your corporate smtp mail gateway server. Below is an example Please allow SMTP traffic at smtpgate. Hostname. com IP 9. Function Oracle production DB Outgoing email myappmycompany. Amount emails per month around 5. After that your mail admins will add a sender IP address to a corporate SMTP mail server to allow the sender Linux server access the SMTP server. This will enable the SMTP server sending emails on behalf of the sender your Oracle database Linux box. Note that the mail server can check if the sender email exists. If not, you can send an email from a dummy email account. Sending email from Oracle database via SMTP. Place twice in the below procedure your actual smtpserver name. Connection utlsmtp. Data varchar. 23. Connection UTLsmtp. UTLsmtp. heloobj. Connection, lt smtpserver. UTLsmtp. mailobj. Connection, fromm. UTLsmtp. rcptobj. Connection, too. UTLsmtp. Connection.

In case of following ORA error go to step 2 and 3 ORA 2. SMTP transient error 4. Service not available. ORA 0. 65. 12 at SYS. UTLSMTP, line 2. ORA 0. SYS. UTLSMTP, line 9. ORA 0. 65. 12 at SYS. UTLSMTP, line 1. The ORA 2. SMTP transient error 4. Service not available error indicates that the problemis not with the UTLSMTP package but the fact that your database servers network configuration doesnot allow it to contact an external SMTP server. In case a following Oracle error, go to next step and enable ACL in Oracle 1. ERROR at line 1 ORA 2. SMTP transient error 4. Service not available. ORA 0. 65. 12 at SYS. UTLSMTP, line 5. ORA 0. SYS. UTLSMTP, line 1. ORA 0. 65. 12 at SYS. UTLSMTP, line 6. ORA 0. TESTMAIL, line 3. ORA 2. 42. 47 network access denied by access control list ACLORA 0. Enable access control list ACL for your network hosts on 1. The network utility family of PLSQL packages, such as UTLTCP, UTLINADDR, UTLHTTP, UTLSMTP, and UTLMAIL, allow Oracle users to make network callouts from the database using raw TCP or using higher level protocols built on raw TCP. As of Oracle 1. 1g a new package DBMSNETWORKACLADMIN allows fine grained control over network hosts access using access control lists ACL implemented by XML DB. Below I show major steps that are required to enable ACL for user SCOTT. You have to run them as SYS or SYSDBA user. Read Oracle documentation for more details. Create an ACL with one database user in Oracle database. BEGIN. DBMSNETWORKACLADMIN. CREATEACL. acl smtp gate permissions. Permissions for smtp gate. SCOTT. isgrant TRUE. Assign an ACL to one or more network hosts. BEGIN. DBMSNETWORKACLADMIN. ASSIGNACL. acl smtp gate permissions. Confirm the created ACL is correct. SELECT host, lowerport, upperport, acl. FROM   dbanetworkacls. TOCHARstartdate, DD MON YYYY HH2. MI AS startdate. TOCHARenddate, DD MON YYYY AS enddate. FROM   dbanetworkaclprivileges. So that was my action plan for providing your applications an ability to send email via SMTP protocol from an Oracle database Linux server using a real example with UTLSMTP package including ORA error handling and ACL creation on Oracle 1.
