DDM file between v7r3 and v5r4

This involves two machines, one running v7r3, the other v5r4.

I was trying to determine if I can have an RPGLE program on v7r3 read a SQL ALIAS table that points to a remote table.

On v5r4 there's a multi-member file of which I only want a particular member.  So on that machine, I created an alias:

 CREATE ALIAS mylib/myAlias for mylib/myFile (myMbr)

On v7r3,

 CREATE ALIAS mylib/myFile FOR rmtv5r4/mylib/myAlias

So far so good.  On v7r3, a "SELECT * FROM mylib/myFile" returns the records from myMbr on the remote v5r4 machine.

I wrote RPGLE program TESTALIAS on v7r3 which reads the first record from myFile, displays the key fields, then ends. The first issue was it wouldn't compile because it couldn't get the external field definitions from myFile.  So I copied the file definition from v5r4 to v7r3 as myDefn and used that in the EXTDESC key field on the file spec.  That got it compiled.

Here's the fun part.  When I ran it I got some errors:

CALL TESTALIAS
 [CPI9160] Database connection started over TCP/IP.
 [CPI9200] DDM object SYSCDEP1 in UTLIB uses remote object UTLIB/SYSCDEM1.
 [CPF9162] Cannot establish DDM connection with remote system.
    Cause . . . . . :   An error occurred during distributed data management (DDM)
      initialization while attempting to establish a connection at the remote
      location OCAL 0000.
    Recovery  . . . :   See previously listed message CPF4364. Correct the errors
      and then try the request again.  If message CPD3E34 is listed, see the
      message listed before it for meaning of error code.

The "Recovery" is interesting because there is no "previously listed message CPF4364". However,
 the "Cause" hints at the problem with "remote location OCAL  0000."

Has anyone seenanything like this?
