В Oracle11g для любого пакета, выполняющего внешние сетевые вызовы (UTL_SMTP, UTL_MAIL) необходимо создать список ACL, включить в него пользователя или роль и предоставить списку привилегию сетевого уровня.
Посмотреть, есть ли какие-либо ACL в базе можно так:
select acl , host , lower_port , upper_port from DBA_NETWORK_ACLS;
Создаем список ACL, включаем в него пользователя и предоставляем списку привилегию сетевого уровня:
begin
dbms_network_acl_admin.create_acl(
acl => 'mail-server.xml'
,description => 'Permission to make connections to mail server'
,principal => 'SCOTT'
,is_grant => TRUE
,privilege => 'connect'
);
dbms_network_acl_admin.assign_acl(
acl => 'mail-server.xml'
,host => 'my-SMTP-servername'
,lower_port => 25
,upper_port => NULL /* открывается только порт 25*/
);
end;
ещё пример:
begin
-- Создание списка ACL
dbms_network_acl_admin.create_acl(
acl => 'oracle-permissions.xml'
,description => 'Network permissions for www.oracle.com'
,principal => 'WEBROLE'
,is_grant => TRUE
,privilege => 'connect'
,start_date => SYSTIMESTAMP
,end_date => NULL
);
-- Назначение привилегий
dbms_network_acl_admin.create_acl(
acl => 'oracle-permissions.xml'
,description => 'Network permissions for www.oracle.com'
,principal => 'WEDROLE'
,is_grant => TRUE
,privilege => 'connect'
,start_date => SYSTIMESTAMP
,end_date => NULL
);
-- Определение допустимых адресов
dbms_network_acl_admin.assign_acl(
acl => 'oracle-permissions.xml'
,host => 'www.oracle.com'
,lower_port =>80
,upper_port => 80
);
end;

procedure change_assign_acl;
