I haven't done this before, but it should be possible. I think that if you
review the whitepaper and instructions on setting up a single-instance database
to be managed by Clusterware, that may help. In there, you'll see some
"special" setup steps using crs_setperm to set the ownership of a resource (the
application VIP) to be a different user (root). I think the same could be done
with an alternate listener resource and some other unprivileged user. In that
same whitepaper, you'll see instructions on how to set up a listener resource
manually which will also be helpful. If you combine the two sets of commands--I
think there may be a solution to your issue therein.
The whitepaper is on OTN under the RAC or Clusterware sections. Email me if you
don't find it.

Subject: CRS/RAC external-procedure handling
We're planning to migrate an existing application which requires an external
procedure into a recently-created 10.2.0.3 RAC environment on Solaris 10. At
this point we've created a separate IPC-only listener on each node to handle
extproc calls, and have validated that it allows us to invoke the procedure
successfully.
The next thing we'd like to do is get the extproc listener running as a limited
OS user, rather than under the oracle account. Can anyone tell me if this is
possible when the listener is managed through CRS? We don't mind writing a few
scripts, if necessary, but would prefer not to duplicate the CRS
monitoring/restart infrastructure.
My apologies if this is rather basic... I'll happily accept a pointer to the FM
to R. :) We're still a bit new to the whole CRS/RAC environment, and it's
entirely possible that I simply don't know where to look.
Thanx!
