RE: YAIQ - Yet another ignorant question: multiple LPARs.

Okay. I was trying to make a generic comment.

DRDA is an architecture. All DB2 instances support DRDA.

The Relaional Database Directory is the i object that is used to
describe the connection to other database machines and instances that
support DRDA. You can put other databases in there too, but you have to
install a driver. The driver for DRDA databases is supplied with the
system.

When you create a DDM file, you specify a relational database directory
entry.

When you CONNECT with SQL you specify a relational database directory
entry.

A relational database directory is often referenced as a remote
relational database directory.

Not the same thing. I should have said DDM *usually* *uses* DRDA. When
you use DDM to connect to a remote database, you *usually* use the i
DRDA driver. When you use SQL to connect to a remote database, you
*usually* use the i DRDA driver.

I am not so sure they are the same.  DDM can't be used by SQL.  DRDA had
better be.
