The startd/ignore_error property (see svc.startd(1M)) lets you tell startd to ignore core and/or signal events in a service.

Sendmail is another application with such a constraint: you don't want a user to be able to restart sendmail by sending a signal to something running out of their .forward or by running broken programs out of their .forward. So in
/var/svc/manifest/network/smtp-sendmail.xml we do the following:

         <property_group name='startd' type='framework'>
                 <propval name='ignore_error' type='astring'
                     value='core,signal' />
         </property_group>

You lose most of your restart benefits (sendmail will still restart if its contract empties out), but you retain the ease of administration that SMF offers.

You'll might want to do something similar in your Oracle manifest.
