Question: How do I send a text message
from the OEM? I wish to create alerts to send text messages to
my phone from OEM. I am a beginner and want an easy solution
to sending OEM text messages to my phone.
Answer: Sending
a text message to your phone is done via e-mail, and start my
creating an e-mail address that routes to your texting service on
your cell phone. Then, you need to configure your OEM mail
server.
I don't recommend using OEM for sending e-mail alerts because a
custom solution is wide open, you know how it works, end-to-end, and
you can customize it far beyond the one-size-fits-all constraints of
the OEM Mail Server configuration. If you know Oracle, you can
create a more robust e-mail alert mechanism
using PL/SQL and utl_smtp to send text messages.
For automated notification, a SNMP interface can be
easily configured to have OEM send the DBA a notification e-mail
whenever the threshold value has been exceeded. This alert can be
an e-mail, a telephone message or an alert on the OEM2GO PDA device.

OEM e-mail server is not as robust as a custom tailored e-mail
program
I have more complete details on creating a custom monitoring and
e-mail alert infrastructure in my latest book "Oracle
Tuning: The Definitive Reference, 2nd Edition".
For experts, sending
e-mails in Oracle is normally done
within PL/SQL. Also, see my notes on using the
utl_smtp package for sending e-mails within Oracle to mobile
devices.
As for what e-mails alerts to send, you start by
defining your
own alert thresholds. You may also want to send email
alerts to your SMS mobile device for
suspicious alert log messages.
