For better or worse, I have had some experience with SAP consultants.

You will find that an unusually large percentage of them will insist that
everything be done "by the book"

The problem is that the book they are going by is often outdated
or just plain wrong.

I have however had the pleasure of working with some SAP folk
that are very good.  A couple of them have even been very good
with the database side.

You will find by searching on the SAP support site that there are
internal folks there that are extremely good with Oracle.  These
can be your ally when dealing poorly informed SAP consultants
and  BASIS admins.

For instance, you will find this SAP note quite invaluable:
825653 - Oracle: Common misconceptions

It can be used to refute some of the misconceptions
held by SAP folks, and as it comes from SAP, they
must pay attention.  :)

It may or may not be necessary.

I can't recall under what circumstances you may need to use
this in an SAP context.  If you do however, then connections
to the database need to be controlled via SQLNet invited nodes.

There is someone a couple years ago I had this discussion with,
and that is how they had it setup.

Personally, I don't allow it to be set here.

If you do allow it to be set, another precaution is to be sure that
the SAP accounts created in the database are created to include
the domain name.

This requires that the the env (or registry) variable
which is the default anyway.

eg.  assuming a DEV system,  and a domain of MYDOMAIN.COM, the users
would be:

Sorry, that is a fact.
It is required for the SAP DBA utilities.

If not allowed, the SAP BASIS admins will not be able to do any
jobs that require DBA access.

It may just be required for the system to work at all, I don't know.
