Send Email with Email Delivery Service on Autonomous Database
Describes the steps to send email using UTL_SMTP on Autonomous Database on Dedicated Exadata Infrastructure.
To send email using
UTL_SMTP:
See UTL_SMTP for further reference.
See Notes on the Use of Database PL/SQL Packages for more information about using UTL_SMTP with Autonomous Database.
SMTP Send Email Sample Code
Shows sample code for sending email with UTL_SMTP on an Autonomous Database.
Sample Code
-- As ADMIN user, set up ACE to access SMTP host
connect admin/[password]@[ADBD-host]/[pdbname]_tp.atp.oraclecloud.com
begin
DBMS_NETWORK_ACL_ADMIN.APPEND_HOST_ACE (
host => '[SMTP_Server_address]',
lower_port => 25,
upper_port => 25,
ace => xs$ace_type(
privilege_list => xs$name_list('smtp'),
principal_name => '[database_user]',
principal_type => xs_acl.ptype_db));
end;
/
-- If using secure SMTP, set up ACE to wallet for certificate-based secure (TLS) email
declare
m_wallet_path VARCHAR2(512);
begin
select property_value into m_wallet_path
from database_properties
where property_name like '%SSL%';
m_wallet_path := 'file:' || m_wallet_path;
DBMS_NETWORK_ACL_ADMIN.APPEND_WALLET_ACE (
wallet_path => m_wallet_path,
ace => xs$ace_type(
privilege_list => xs$name_list('use_client_certificates'),
principal_name => '[database_user]',
principal_type => xs_acl.ptype_db));
end;
/
-- As ADMIN or regular database user with privileges set up above, use UTL_SMTP to send email
connect [database_user]/[password]@[ADBD-host]/[pdbname]_tp.atp.oraclecloud.com
